Glucose levels and exercise – frequently asked questions

Nick Caracandas from Diabetic Athletic answers frequently answered questions regarding glucose levels and exercise.


Cardio

Q: What should I do if my blood glucose is high before I do cardio?

If your blood glucose is high pre-cardio, consider taking half (or less) of your usual correction dose and assess 25 minutes into training. A full correction dose might stimulate a hypo.

Q: What should I do if my blood glucose is low before I do cardio?

Consume an adequate amount of carbohydrates to bring blood glucose back into range. Cardiovascular exercise has the tendency to lower blood glucose, thereby having the potential to amplify the hypo. Short bouts of High-Intensity Interval Cardio can increase blood glucose levels. But the nature of the cardio after may lower blood glucose back down again, defeating the purpose.


Weight training

Q: What should I do if my blood glucose is high before I weight train?

If your blood glucose is high pre-weight training, consider taking your usual correction dose and assess 25 minutes into training. Strength training has the potential to increase blood glucose levels. Taking less than your normal correction dose may not account for the blood glucose rise that often accompanies this form of stressful training.

Q: What should I do if my blood glucose is low before I weight train?

Consume a liquid carbohydrate sports drink. This acts fast and won’t bloat you like a solid food meal. The number of carbs to consume will largely depend on the severity of your hypo. Weight training can increase your blood glucose levels. Accommodate this when eating and avoid over-treating your hypo with too many carbs, which will inescapably drive you into hyperglycaemia. Short bouts of High-Intensity Interval Cardio can increase blood glucose levels. The strength training that follows may increase blood glucose further and get you back into a safe range: 15-30 secs on with 45-60 sec active recovery. I personally use the bike and row sprints. The severity of your hypo will largely be down to how much insulin is circulating in your system. The more insulin, the more severe the hypo. Subsequently, carbohydrates may be needed.

Other

Q: As a female, will I get big and bulky like a bodybuilder if I lift weights?

No. You are not set up hormonally for rapid muscle gain compared to a male.

Q: What is the best form of cardio to burn fat?

A format you prefer and can consistently do on a regular basis.

Q: Can I train abs every day?

If you wish. Just make sure you hit them from different angles. Lateral, flexion, rotation, and extension.

Q:What if I am sore after a workout? is this a bad sign? Am I injured?

Not always.Soreness after a training session indicates you’ve pushed your body more than it’s normally exposed to. This dull pain is termed as Direct Onset of Muscle Soreness (DOMS). Don’t panic. It usually subsides after a few day recoveries. To recover well, you must have appropriate rest and food. You also need to manage your diabetes extremely well. Hyperglycaemia will jeopardise training recovery and prolong muscle soreness. The better the control in conjunction with good quality food and rest, the quicker DOMS will subside.

Q: Do you have to be sore and have a good workout?

No.

Q: Do I have to push myself to complete exhaustion every training session?

No. Never leave the gym feeling damaged, vile or lifeless. Stimulate don’t obliterate.

Q: When is the best time to weigh myself?

First thing in the morning after your bowel movement, without clothes on. Use the same scale every time to keep things accurate. If you do weigh later in the day, keep the time of weighing consistent over a number of weeks.

Esther Rodrigues – My hero calls me Mom

Esther Rodrigues, a T1D Mom, shares the joys of seeing her son, Mikyle, celebrate his 21st birthday.


Esther Rodrigues stays in Cape Town with her husband, Antonio, and  their three children, Kelsey, Mikyle and Jayden.

I am a T1D Mom, who is exceptionally proud of my son, Mikyle Rodrigues, who turned 21 on 20 May 2020.

Mikyle is a strong T1D Warrior who never gives up. In his quiet confidence, he has the strength of a lion, a will to survive and a burning desire to overcome all obstacles in his way.

Currently, my son’s life consists of studies, exercise, eating lots of food, playing PS4 and managing his Type 1 diabetes.

Our family and friends are supportive and assist us wherever possible. Two and a half years ago, Mikyle fell in love, and that gave him reason to live, reason to fight and unconditional love.

Diagnosis

Mikyle was diagnosed at the tender age of 10 in August 2009. I did not know anything about Type 1 diabetes. I was completely dumbfounded with the diagnosis. In the blink of an eye, without any warning, our lives changed forever. Nothing can prepare you for this…Google became my best friend.

As a T1D Mom, I did not know how I was going to do this. I felt as if there was a huge hole in the centre of the earth and I was being sucked in. It was only once we came home, with all the reading and research I did, that I realised what Type 1 diabetes was all about.

The first few years were fine until puberty struck and caused havoc in our lives. We pushed through as best we could but we were advised to look at an insulin pump. Pumps are very expensive and while trying to save towards one, Mikyle was gifted with his first insulin pump by another T1D Warrior, Rowena Carmyn Webb. Rowena gave it to Dr Tracy Janse Van Rensburg, Mikyle’s doctor at the time, to bless a child with it and Tracy chose Mikyle. Sadly, Rowena, an incredibly generous woman, passed away on 22 June.

Eating habits changed as a family

As a family, we love eating. We celebrate with food. Eating habits had to be altered, sugar was removed from our household and sugar-free drinks were bought. Xylitol was used for baking, because Mikyle has a sweet tooth.

I remember the highlight of his school camps were ending the day with hot chocolate topped with marshmallows. So, I searched high and low and made sure that I packed his sugar-free hot chocolate and sugar-free marshmallows when he went on school camps. I did everything in my power to convert the things he liked into sugar-free treats!

Insulin

Mikyle uses a Medtronic insulin pump and Humalog insulin. To test his glucose levels, he uses a Freestyle Optium Glucometer with Freestyle testing strips.

What Mikyle enjoys

Mikyle enjoys exercise, with his favourite being weight training and recently he started taking interest in cardio, specifically boxing.

Since he has joined the gym, he heals faster, and his immune system is much stronger. The blood glucose control is also much better.

Mikyle enjoys eating food. If you want to steal his heart then cook for him. He enjoys most foods, with emphasis on healthy foods. He is currently studying Dietetics (2ndyear) at Stellenbosch University so he knows the importance of consuming healthy foods.

Most of the time, he is playing games on his PlayStation, driving and spending time with his girlfriend, Tamia.

Lessons learnt

I was prepared to help my son grow into a strong, independent young man who could do anything he puts his mind to, but it turns out that he is stronger than I could ever have imagined. With many prayers and the grace of God, he celebrated his 21stbirthday with us as a family.

I believe that God gives his hardest battles to his strongest soldiers, and took some of the strongest women and made them T1D Moms.

My hero calls me mom.

Diabetic erectile dysfunction

Dr Larisse Badenhorst helps us understand why men who have diabetes may also suffer with diabetic erectile dysfunction.


Understanding erectile dysfunction

Erectile dysfunction (ED) is defined as the inability to get or maintain an erection firm enough for sex.

A lot must work together to get an erection. Men need healthy blood vessels, good blood supply, intact nerves, balanced and adequate hormones (these include oestrogen, testosterone and thyroid hormones), and a desire to be sexually stimulated.

This is a complex interaction of vascular, neurological, hormonal and psychological systems. It is therefore imperative to seek expert help when you are experiencing ED.

Screening, monitoring and appropriately treating diseases that are comorbid with erectile dysfunction is essential. This will enhance life quality and improved motivation in men with existing erectile dysfunction comorbidities or risk factors. 

Diabetic erectile dysfunction

Erectile dysfunction is a common and distressing complication of diabetes. Both Type 1 and type 2 are risk factors for the development of erection problems.

Many unique characteristics distinguish these two, including insulin and cholesterol levels, obesity status and inflammatory agent profiles. The causes in diabetic erectile dysfunction are multifactorial and it is found that it is more severe and more resistant to treatment when compared with non-diabetics. Erectile dysfunction in diabetics develops 10 to 15 years before men without diabetes.

There are many associated factors, namely advancing age, duration of diabetes, poor glycaemic control, high blood pressure, high cholesterol, sedentary lifestyle (which pertains to lack of exercise and increased weight), smoking, presence of other diabetic complications, depression and other psychological diseases, prostate problems and low testosterone levels.

As important as these are in leading to erectile dysfunction, the medication used in treating these conditions are as important. There are a lot of medicines used to treat other conditions that can make erectile dysfunction worse.

It’s vital to screen for these other conditions in erectile dysfunction sufferers. Premature ejaculation and low libido is commonly associated with diabetic erectile dysfunction. It is important to see to these as well if present.

Diminished erection spontaneity, rigidity (firmness) and/or sustaining capability also negatively affect mood, self-esteem, and confidence. These can compromise motivation to be compliant with medications that treat diseases comorbid with erectile dysfunction.

Managing erectile dysfunction

Seeking medical expertise is imperative to treat the cause and comorbid conditions that can lead to ED. The following treatment is important in diabetic erectile dysfunction, but also important to be addressed in non-diabetics.

Optimising glucose levels is vital, especially in young men with diabetes. Lifestyle modifications are important; these include dietary changes, cessation of smoking and weight loss. Managing other comorbidities adequately is also of utmost importance.

As said before, optimising treatment of diabetes and other comorbidities, and reviewing all medication used much be done, as these can play a vital role in worsening erectile dysfunction.

Tablets

Specific treatment for erectile dysfunction is phosphodiesterase type 5 inhibitors (PDE5I). These include tablets like Viagra, Cialis and Ciavor. These tablets work extremely well, but it is important to be prescribed by a medical professional who will make sure there are no contraindications in the use of these, as well as educating you on the side effects and risks.

Injections

Intracavernosal injections (these are injections administered directly into the penis) also work very well and are commonly used if PDE5I don’t work or contraindications to their use exist.

The dosage needed must be monitored by a medical expert because prolonged erections (known as priapism) can result from the use of the injectables and can have long-term effects.

Pumps

Vacuum devices or pumps are also available. They draw blood into the penis to then obtain an erection and a ring is used to then keep the blood within the penis to maintain the erection.

A common problem is that the device is not used correctly and therefore a lot of men think that it doesn’t work.

Platelet rich plasma

A newer treatment available is platelet rich plasma (PRP). This involves using the person’s own blood products to promote healing and rejuvenation in certain areas of the body. It has gained a lot of popularity in sexual medicine but is still seen as experimental in treating things like erectile dysfunction.

Treating possible underlying psychological problems are very important and seen as key in patients with performance problems.

With the pharmaceutical advances and expanded knowledge of the effects of lifestyle on sexual health, there is seldom a reason for a man to suffer bad erections in this day and age. The earlier you treat, the better the outcome for your general health as well as long-term effects.

Healthy herbs and spices for cooking

Dietitian, Retha Harmse, informs us on how to make low sodium meals by using healthy herbs and spices.


Wintertime calls for more comforting stews, soups and curries and suddenly cold salads seem much less appealing. But with that comes another risk that people living with diabetes need to steer clear of: falling in the high salt trap.

We run the risk of wanting quick and easy convenience during winter, using pre-packaged sauces or stock cubes to limit the time spent cooking in the cold kitchen and increase the time under a warm blanket or close to the heater.

These convenient alternatives unfortunately often have a very high sodium (salt) content, and with the risk of comorbidities already being increased in diabetes patients and needing to keep blood pressures in check, the convenient way is not the healthiest way.

Avoiding the high salt trap

Choose food and beverages that are lower in salt and prepare food with little or no added salt:

  • Choose fresh, simply prepared food as often as possible.
  • Limit packaged, processed, and ready-to-serve food, such as snack food, processed meats, regular canned and dried soups, frozen meals, cheese, gravies, dressings and sauces.
  • Use no added salt or reduced-sodium ingredients whenever possible.
  • Read labels – if the sodium content in the nutrition facts table is 5% or less of the DV (daily value), then the product is considered low in salt.

Practical tips to reduce salt in cooking

This may seem easier said than done, but remember breaking a habit does take time. Herewith a few step-by-step tips.

How to add less salt to food:

  1. One small step at a time
  • If you are used to adding salt at the table, try to break this habit first. Remove the saltshaker from the dinner table (often this already makes a huge difference – out of sight, out of mind).
  • Start using less salt and sodium rich spices (like stock cubes other salts, etc.) when you are cooking.
  • Reduce your salt intake gradually.
  1. Tips to cook with less salt
  • During the cooking process, taste your food as it may not need added salt.
  • Remember: if you’ve already added salty spices or a stock cube, you do not need to add salt too.

Healthy herbs and spices

But now you might ask: what should I use to flavour my food if I don’t use salt? To make your food tasty try these herbs and unsalted spices instead of salt:

  • Lemon juice or vinegar.
  • Herbs like Italian herbs mix, parsley or rosemary.
  • Spices like curry powder, paprika or pepper.
  • Garlic, ginger, chilli and onions.

Which foods to eat more often, only sometimes or eat less often

Foods low in salt
(eat more often)

  • Cakes, pastries and biscuits/ cookies
  • Table sauces (tomato sauce and mustard)
  • Salad dressings
  • Mayonnaise
  • Convenience meals

 Be salt aware

  1. Use little or no salt in cooking – try using extra herbs and spices instead such as black pepper.
  2. Leave the saltshaker off the table.
  3. Cut down on salty processed foods and ready meals and try and make your own if you can.
  4. Check out food labels for salt and go for lower salt choices. There can be a really big difference between different types and brands.
  5. Compare salt levels among similar products and try to choose those lower in salt.
  6. Ask in restaurants and take-aways for no added salt.
  7. Be wary of fancy gourmet salts and salt substitutes claiming to be better for your health than table salt. These product ranges are still likely to add some form of salt to your diet.

10 foods to build immunity

The Heart and Stroke Foundation South Africa advises what foods should be eaten to build immunity during this viral era.


While many people are stocking up on immune boosters, vitamin C tablets and green juices, we’ve put together a few ideas on the type of nourishment our bodies need as we fall into winter. More importantly, as we find ourselves caught up in this viral era, here are 10 top foods to build immunity, without compromising your diabetes.

  1. Citrus fruits

All citrus fruits, such as oranges, grapefruits and lemons are high in vitamin C, which acts as an antioxidant. Antioxidants help fight free radicals; a type of unstable molecule known to damage the immune system. Vitamin C also increases the production of white blood cells which are key to fighting infections.

Keep seedless oranges in a fruit bowl (up to four days with peels intact) for easy grab-and-go snacks.

When it comes to fruits, try to limit your intake to two fruits per day and where possible a fruit should be consumed with the skin on for that extra fibre.

  1. Spinach

Spinach is rich in vitamin C. It’s also packed with numerous antioxidants and beta carotene, which increases the infection-fighting ability of your immune system. Spinach is healthiest when it’s cooked as little as possible so that it retains its nutrients.

  1. Yoghurt

Yoghurt is a fermented food that naturally contains lots of probiotic cultures. These cultures help to increase the good bacteria in your gut – the place where more than 70% of your immune cells live.

  1. Oily fish

Salmon, tuna, sardines and other oily fish are a rich source of omega-3 fatty acids. Omega-3 fatty acids suppress inflammation and keep immunity in check.

Fatty fish also contain vitamin D which helps regulate the immune system and is thought to boost the body’s natural defences against diseases.

Vitamin B6 found in fatty fish is vital to supporting biochemical reactions in the immune system.

Make sardines in tomato sauce on toasted low-GI bread with a few slices of avo – creamy and delicious, or if you prefer add anchovies for a salty kick.

  1. Mushrooms

Mushrooms contain antioxidants that provide anti-inflammatory and immunity protection. Cooking mushrooms lowers their anti-inflammatory compounds so it is best to eat them raw or lightly cooked.

  1. Almonds

Almonds are packed with vitamin E, which is a powerful antioxidant. Maintaining ample levels of vitamin E is crucial for maintaining a healthy immune system.

Almonds are also a source of zinc; zinc is an essential mineral involved in the production of certain immune cells.

For a dose of protein and healthy fats, add a spoonful of almond butter to oatmeal.

  1. Green tea

Green tea has high levels of epigallocatechin gallate (EGCG) which is a powerful antioxidant that enhances your immune function.

  1. Ginger

Ginger is another ingredient many turn to after getting sick. It helps to decrease inflammation, which can reduce a sore throat and other inflammatory illnesses.

  1. Garlic

Early civilisations recognised garlic’s value in fighting infections. It’s immune-boosting properties come from a heavy concentration of sulphur-containing compounds, such as allicin.

  1. Turmeric

Research shows that high concentrations of curcumin, which gives turmeric its distinctive colour, help to prevent inflammation.

Use a pinch of turmeric in scrambled egg. If you or your family are new to turmeric, this is a great place to start because the colour is familiar and the flavour subtle.

Make tea by simmering turmeric with coconut milk to make an earthy and comforting beverage aka the popular Golden Milk.

This winter, plan your meals and snacks to include these top 10 powerful immune boosters.

Winter foot care advice

Podiatrist, Dennis Rehbock, shares winter foot care advice for people living with diabetes.


While winter in South Africa may not be extremely cold and snowy like other places in the world, it can be unpleasant and pose some dangers to the feet of a person living with diabetes.

Foot care is of great importance to a diabetic patient and should be practiced every day. But, in winter it’s even more important if the patient is high risk, such as poor circulation, Raynaud’s disease (a condition in which some areas of the body feel numb and cool in certain circumstances), peripheral neuropathy (weakness, numbness and pain from nerve damage, usually in the hands and feet), or any foot ulceration.

Winter foot care tips

  • Check your feet every day. Do this yourself if you can or get a family member or helper to do it. This will enable you to see any problems before they happen.
  • Inspect for any lesions, discolouration, swelling, dryness, corns, cracked heels, peeling skin (especially in between toes), pain and numbness. Anything new or unusual should be seen to as soon as possible.

Even in this COVID-19 lockdown period you may and should go to your podiatrist or diabetic doctor for any problem or foot problem that you are having.

Keep your feet dry and warm

  • Wash your feet daily. Dry them very well, especially in between the toes. Be gentle.
  • If necessary, use foot powder on them before you put your socks and shoes on.
  • If you have very dry feet then moisturise them daily after your bath or shower.
  • Use an urea-based cream that is especially for dry feet. There are many on the market these days.
  • Do not cream in between your toes. Rather keep that area dry. 

Socks

  • Any socks that are worn should be soft, warm, comfortable and should not have seams in them that could damage your skin. You do get special socks for diabetic feet to protect them.
  • The sock material should be a moisture-wicking material to keep the feet dry. Cotton, wool and merino wool is good for this purpose.
  • Modern sports and running socks are also made from materials like Drynamix and merino wool (see Falke and Balega socks).
  • Some sock materials are infused with silver and copper to help with bacteria.
  • Change your socks daily.

CAUTION: If you have cracked wet itchy skin in between your toes, go and see your podiatrist. It may be a fungus (Athlete’s foot) that needs treatment.

Shoes

  • In winter, it is best to wear closed shoes that will keep your feet warm and protected. They must keep your feet comfortably warm to help prevent chilblains, ulceration and Reynaud’s.
  • The shoes should fit well and not cause any pressure or friction. They must also have good traction to help prevent slipping and falling.
  • When you are around at home it is okay to wear thick soft warm sheepskin slippers.

CAUTION: Please do not heat your feet up in front of a fire, or a heater, or in any hot bath or footbath. Electric blankets must be used with extreme care.

Dry skin and hard skin

  • If you have dry skin on your feet, moisturise them as mentioned.
  • If you have hard skin, like corn, blisters and callouses, refrain from any self-treatment. Do not cut them yourself or use any acid-based creams on them. This is dangerous if you have poor peripheral circulation or peripheral neuropathy.
  • Go and see your podiatrist for professional treatment of these lesions.

CAUTION: Do not cut these lesions yourself.

Nail care

  • If you can reach your nails and see them well then you may carefully cut your own nails. Cut straight across and file them to make them smooth.
  • If you cannot reach or see them well then please do not cut them yourself. Go and see your podiatrist for regular foot care and they will cut your nails.
  • Other nail pathologies also need treatment. Damaged nails, ingrown nails, fungal nails can also be treated.

Peripheral nerve changes

  • Nerve changes in the feet can occur in patients living with diabetes. If your feet go numb (peripheral neuropathy), it can be a bad thing.
  • Nerve changes can affect your ability to balance, to feel pain and foot damage. Your ability to feel heat could also be affected and this may cause foot damage without you knowing.
  • Check the temperature of your bath before you get into it.
  • Do not sit in front of a heater or fire to warm your feet. You could burn them.
  • Keep your blood glucose levels well-controlled. Monitor your diet, exercise regularly, and avoid smoking.
  • Have your feet screened once or twice a year for neural and vascular changes.

Circulation

  • The peripheral circulation is often affected in people living with diabetes. This can lead to minor vascular lesions in the feet, like chilblains, and to more serious lesions, like ulceration.
  • Chilblains are a typical lesion that can occur in very cold weather, especially with sudden changes of temperature. If your circulation is also poor then you are at great risk of getting them.
  • The lesions present as red/blueish patches on the skin of the feet and toes. This can also occur on the hands or other exposed areas. The small blood vessels go into a spasm and are usually painful. They are usually self-limiting, but if necessary, they need treating.
  • Keeping your feet gently warm, and not smoking is important as smoking is a factor in the cause of chilblains. There are rub-on-creams that may help.
  • In more severe cases, oral medication may be necessary to improve the peripheral circulation.
  • Exercise also helps improve the peripheral circulation.
  • It’s been observed that COVID-19 positive patients may have chilblain-like symptoms on the feet. Painful lesions that look very much like chilblains can appear in these patients, so care must be takes in the diagnosis of the chilblains.

Summary

  • Go and see your podiatrist regularly (once or twice a year) or if you have any sudden foot problems in winter.
  • Do not treat your own feet. Look after them, observe them daily, but go for professional treatment when necessary.
  • Be very careful of using any unusual, untested products on your feet. Rather get professional advice.
  • Urea-based foot creams or heel balms are good to use for dry feet.
  • If you see any signs of infection or ulceration on your feet, go immediately to your foot care professional.
  • Smoking is bad for your peripheral circulation.
  • Exercise is good for your peripheral circulation. Get moving and go and walk or run.

How does menstruation affect blood glucose?

Dr Louise Johnson expands on how menstruation can affect blood glucose levels.


Women living with diabetes know that it’s nearly impossible to predict what blood glucose will do during menstruation. Glucose control is a lot more difficult for Type 1 patients than Type 2 diabetes.

Understanding menstruation

It’s important to realise that there are four hormones at interplay during the 28 to 32-day cycle: follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrogen and progesterone.

The primary function of these hormones is to prepare the body for pregnancy. There are three phases:

Follicular phase – the growing of the ovarian follicle (day 1-10)

Ovulatory phase – shedding of the egg cell (day 11-14)

Luteal phase – build-up of the endometrium (inner lining of the uterus (womb) and necrosis and shedding (menstruation) (day 15-28)

How hormones affect blood glucose

During each of these phases the different hormones will impact your glucose and insulin resistance differently.

Day 1 to 10: (follicular phase)

The first day of your period (menses) is the start of the first day of your cycle. Insulin sensitivity should be back to “normal” for the period of menstruation since the hormones oestrogen and progesterone are at the lowest value.

At the start of each menstrual cycle, the follicle starts to maturate by forming a large vesicle inside the follicle and then the mature follicle forms. The mature follicle will shed the egg cell (ovulation). The first 10 days, the oestrogen rises slowly.

Day 11-14 (ovulatory phase)

The follicle ruptures at day 14 and the ovum (egg cell) is extruded into the abdominal cavity. This ovum is picked up by the fimbria of the fallopian tubes. This process is ovulation.

During ovulation, the oestrogen level is at its highest and the LH has a burst of secretion from the pituitary. This marks the end of the follicular phase.

Blood glucose will begin to rise as well as insulin resistance. This is due to the rise of oestrogen, LH and FSH to its highest value. This spike of blood glucose will be two to three days. It’s accompanied by a slight rise in body temperature.

Day 15-20

During this phase, LH and FSH drops back to normal values and oestrogen decreases rapidly. Blood glucose values are easier to manage.

Day 21-28

This is the area of highest blood glucose due to rise in progesterone as well as oestrogen and hence insulin resistance. This is the three to seven days leading to your next menstruation. During this time, you would be more ‘resistant’ to basal insulin and would need a few more units to control your blood glucose. This can also be called the premenstrual syndrome (PMS) phase.

A study2 showed beautifully in different Type 1 diabetes patients with continuous glucose monitor (CGM) that the glucose varies between the luteal phase (day 21-28) and the follicular phase (day 1-10).

PMS

Premenstrual syndrome occurs a few days before the next menstruation. The symptoms can be worsened by poorly controlled blood glucose levels.

Symptoms such as tenderness, bloating, grumpiness, and cravings are a few common ones. The food cravings are due to the rise in progesterone. Usually chocolate or sweet things are craved. Manage this by light exercise, sugar-free or fat-free snacks, and extra insulin as needed.

It’s important to remember that not all females have a 28-day cycle. Some may have a slightly longer or shorter cycle. It can vary from 21 to 35 days.

Managing fluctuating hormones every month

  1. Keep a diary of your period for three months to establish the length of your cycle and the time of ovulation. This will help you to adapt better to higher blood glucose. There are apps that can be used such as mySugr, Clue and One Drop.
  2. Diarise your blood glucose for three months to establish the two periods of increased insulin resistance during ovulation and just before menstruation.
  3. There is a need to increase basal insulin with 25 to 40% during these two periods. Start low and slowly document your correct basal increase during these times to keep glucose levels controlled.

Why is it important to know your menstrual cycle?

The menstrual cycle affects your ability to control your glucose for about 35 years. Menarche (start of menstruation) at around 12 years of age to menopause at around 45 years of age is a significant duration of time to struggle with bad glucose control. This can lead to unnecessary complications both microvascular (eyes, feet, kidney) and yeast infections vaginally due to poor control.

Women on the contraceptive pill

There are a variety of contraceptive pills on the market. Your gynaecologist will suggest the correct one for you. It’s important to remember that the pill can increase insulin resistance and that you should increase your insulin accordingly with the help of your doctor.

This increase in insulin resistance occurs three to six months after the oral contraceptive is started. It is thought that the progesterone may induce insulin resistance through its inhibition of insulin signalling in the adipocytes (fat cells).3

Menstruation is the start of womanhood and should be a great time in a woman’s life. Fertility and the prospect to be able to have a baby should always be cherished and respected.

Remember that good control (HbA1c of 6%) is important before planning a baby. Discuss your menstrual problem and proper family planning with your doctor and enjoy being a woman.

Eat for energy this winter

Dietitian, Mignon Jordaan, advises us how to eat for energy this winter so the winter-blues will be a thing of the past.


Cold weather can be dreadful but the food that warms you up is often so delightful. If the desperate need for comfort food or the so-called winter-blues binge eating happens, there is a perfect explanation for this, and you’re not alone.

Research1 has shown that people with diabetes tend to have a higher average fasting glucose level and HbA1c value during the winter months. The findings in this study was mainly related to less physical activity and low immunity leading to seasonal infections (less sunlight exposure equals low vitamin D levels equals low immunity).

SAD

Seasonal affective disorder (SAD) is defined in the 2017 Journal of Global Diabetes and Clinical Metabolism as a seasonal depression and a mood disorder subset in which people that have normal mental health throughout most of the year experience depressive symptoms in the winter.

The typical symptoms to expect when you suffer from SAD are increased appetite, weight gain, declined energy levels, increased sleep desire, loss of interest in usually pleasurable or fulfilling activities, cravings for food items, irritability, and as ruminations of guilt and suicide.

The incidence of SAD in people living with diabetes was found to be high, especially those with diabetic retinopathy. Since diabetic patients may experience similar symptoms of depression, like when blood glucose levels are out of range, it’s important to be aware of symptoms of low mood, cravings and irritability. If symptoms don’t resolve after blood glucose levels normalise, it’s most likely SAD.

The happy hormone (serotonin) is released after a good carbohydrate-rich meal, and tends to be lower during the winter month which leads to more cravings for refined carbohydrates. You would crave a nice warm pizza or warm Malva pudding rather than a whole-wheat chicken wrap.

Avoid rebound hyperglycaemic effect

Many know that a simple carbohydrate, like pizza, will rise your blood glucose levels quickly and lead to a quick drop soon after, making you feel so low in energy and even more hungry for sugar (rebound hyperglycaemic effect).

By changing your mind-set about the type of food and the appropriate portion to keep you satisfied and warm during winter can have a positive impact on your food choices.

Overeating and binge-eating refined carbohydrates can easily be activated by environmental cues, like social gatherings, work functions or habitual hot chocolate every night after dinner, or even just because you’ve been misinformed about a food item that isn’t as nutritious as you might think.

10 ways to be beat low energy winter-blues

The effect of winter blues can be very frustrating and exhausting if you don’t know how to control it. Here are easy tips to minimise low energy.

1. Eat five to six small regular meals

This should be done every two to three hours and should contain a balanced amount of wholegrain starch, lean protein and unsaturated fat to ensure your blood glucose level stay stable for longer. Examples of meals and snacks:

  • Chicken stir fry with brown rice
  • Whole-wheat chicken vegetable pasta
  • Fruit and nuts
  • Whole-wheat crackers with unsweetened peanut butter

2. Make sure you are good to yourself

Have a treat once a week; this needs to be controlled very strictly. Keep it small and have it with a meal to prevent high blood sugar levels.

Recommended snack Teaspoons of sugar Non-recommended snack Teaspoons of sugar
Dark chocolate

½ teaspoon 50g chocolate bar 6 teaspoons
NOMU Skinny hot chocolate

1 Heaped teaspoon with 200ml low-fat milk

½ cup roasted spicy chickpeas tinned in brine/dried with added chilli spices of choice and roasted in oven

0 teaspoons 75g packet jelly babies 7 teaspoons

Comparison of the total teaspoons of sugar in healthy recommended snacks with the total teaspoons of sugar in typical sugary snacks

3. Increase your intake of vitamin D-rich food

Or Buy a vitamin D supplement to prevent vitamin D deficiency and increase your immunity.

Recommended daily allowance (RDA) for vitamin D

Age Male Female
1-13y years 600 IU (15mcg) 600 IU (15mcg)
14-18 years 600 IU (15mcg) 600 IU (15mcg)
19-50 years 600 IU (15mcg) 600 IU (15mcg)
51-70 years 600 IU (15mcg) 600 IU (15mcg)
>70 years

800 IU (20mcg)

800 IU (20mcg)

Food sources rich in vitamin D:

  • Fatty fish like salmon, tuna and mackerel
  • Beef liver, egg yolks and cheese
  • Fortified food like margarine, bread and cereals

4. Be physically active

Moderate physical activity, like brisk walking three to four times a week, will improve energy levels by more sunlight exposure and the release of the ‘good-feeling’ hormone, called dopamine.

5. Increase your fibre intake

Fibre improves the feeling of satiety and improves blood glucose control. Have five fruits and vegetables a day. Include a wide range of vegetables in a warm soup and add fruit to your snacks. This will help you to achieve the fibre recommendation.

6. Make a low-GI carbohydrate part of each meal.

Low-GI food ensures a steady release of sugar in the blood, leading to longer satiety and sustained energy throughout the day. Food sources include:

    • Low-GI seeded or whole-wheat bread
    • Cooled down and re-heated oats, maize meal, Maltabella porridge, potatoes or sweet potatoes
    • Fresh fruit, like apples, pears, strawberries, blueberries and cherries (and many more)
    • Legumes, like sugar or brown beans, hummus, chickpeas and lentils
    • Durum wheat pasta, sorghum, barley, brown rice or quinoa
    • Crackers, like Provita multigrain or whole-wheat

Have a look on http://www.gifoundation.com/ for more examples of low-GI food.

7. Boost the 5 HTP-precursor

The 5 HTP-precursor is responsible to convert serotonin in the body. You can boost your dietary intake of L-tryptophan, which the body converts to 5-HTP. Food sources include turkey, chicken, pumpkin seeds, spinach, milk, and bananas. There are minimal human studies to ensure the success for using a 5-HTP dietary supplement and dietary intake will be sufficient.

8. Make sure that vitamin B-rich food is part of your daily intake

This ensures the successful activation of serotonin. Food sources include wholegrain bread and pasta, lean meat and chicken, seeds and nuts, dark leafy vegetables, eggs and legumes.

9. Have a planned cooking-routine

Make sure you make cooking enjoyable during the winter time and include the whole family. Compile your own recipe book, loaded with delicious soups, stews and casseroles with nutritious ingredients. Have a look on Diabetes South Africa’s website at https://www.diabetessa.org.za/our-recipe-book/ for their amazing diabetic-friendly recipes.

10. Drink six to eight glasses of clean safe water a day

This prevents dehydration and fatigue. During winter, cold water can be difficult to consume so try a warm Rooibos or herbal tea topped with a slice of lemon or mint.

Stay energised this winter by making these 10 steps part of your daily routine and the winter-blues will be a thing of the past.
