In this series, we so far grasped, who are more susceptible to Covid-19 and why, how a general population should diet; by reviewing the World Health Organisation’s (WHO) recommendations during Covid-19 crisis. We also understood the rationale behind those recommendations. However, those with chronic disease are at a higher risk. We learned that controlling such conditions will reduce the Covid-19 associated risk in such patients. Today, we will address what additional improvements can be considered by 463 million diabetes patients across the globe, of which, 1/6th patients are in India.
First and foremost, if you have not checked your blood glucose levels recently, you should get them checked. Especially if they are out of control, controlling them should be your priority. Higher blood glucose is a well-recognised contributor to inflammation as it takes part in the development of diabetes-related macrovascular (like coronary heart disease) and microvascular complications (like diabetic nephropathy and retinopathy) (1–3).
As small as five-per cent weight loss has shown to be potent in controlling blood glucose levels (4). In any disease related to insulin resistance, where the affected is overweight, gradually losing this weight should be a priority aim. In a study by Lean (5), optimal weight loss in people with diabetes (~10kg) with hypertension showed reduction not only in blood glucose levels but also a decline in hypertension. Hence, being in a moderate calorie deficit should be the priority. If you have very high blood glucose and you are being supervised by a clinical nutrition specialist, trying lower carbohydrate diet may provide additional benefits as shown by studies like Sato (6) and Hussain (7) in the short term. However, the long-term adherence issues are common, and that can lead to a reversal of achieved benefits. This can be seen in a study (8) which followed diabetic subjects for more almost four years.
In addition to this, aerobic (cardio) and anaerobic (weight training) exercise addition may prove beneficial as that has shown to affect blood glucose levels favourably (9). This is because blood glucose is used by exercise and insulin-resistant tissues get more sensitive because of the physical activity (9). Moreover, depression is widespread in type two diabetes patients (10), and the lockdown situation may contribute to additional mental challenges. Hence, making sure that you are mentally healthy is essential. In the case of mental issues, reaching psychologists should be the preference. Diabetes often coexists with various co-morbidities and hence, cause and manifestations of those conditions should be attended to as well.
We have previously discussed weight management and exercise implementations through various posts and blogs. We encourage you to go through them and revise WHO guidelines. Implement our two cents with proper support as needed, and let us know if this post was helpful.
