Fasting and Diabetes: Risks, Benefits, and Safety Measures

Do you find it tough to control your diabetes when fasting? Is keeping your blood sugar levels stable during fasting periods a hurdle for you? Remember, many others are in the same boat.

Hence, you must understand the concept of fasting and diabetes. It’s a significant move towards managing your health, especially during fasting times like Ramadan.

That’s why, we’ll explore hands-on approaches to handle diabetes while fasting. From changing your diet to controlling insulin, our goal is to provide you with the information you need to fast safely and successfully, even with diabetes.

Let’s start this journey together.

What are the Risks of Fasting and Diabetes?

If you’re living with diabetes, fasting can present certain challenges. A few key factors shape these challenges —

• The particular form of diabetes you’re dealing with
• The medication you’re using to keep your diabetes in check
• Whether your average blood sugar level (HbA1c) is currently within a safe range for you
• If you’re taking medications such as sulphonylureas and insulin that heighten the risk of hypoglycemia
• If you’re dealing with diabetes-related complications like vision impairment, nerve damage, or heart or kidney disease. Fasting could potentially worsen these issues.

For example, if you’re managing fasting and diabetes type 2 through diet and lifestyle changes alone. Or if you’re on a single diabetes medication that doesn’t increase your risk of hypoglycemia, fasting poses fewer risks if your average blood sugar level is healthy.

How to Adjust Insulin During Ramadan?

Ramadan, the holy fasting month, might require you to tweak your insulin strategy, especially if diabetes is a part of your life. The adjustment depends on several factors including your diet, existing insulin routine, and meal timings during the fast.

Basal Bolus Insulin Therapy

If you’re using basal-bolus insulin, Ramadan requires you to alter your insulin schedule. At sunset, during Iftar, take the entire dose you usually take in the morning. Take half of your usual evening dose at Sahur, the meal before dawn. If you eat dinner, move the entire dose you usually take at lunch to this meal.

For the basal part of your treatment, if you’re using NPH, take half of your dose at Sahur. If you’re using a basal analog, keep the same dose at bedtime.

Premix Insulin Therapy

In line with the South Asian Consensus Guideline, if premix insulin is part of your regimen, the timing and quantity of your doses need to change. Your usual morning dose should be taken at Iftar (the sunset meal), and half of your regular evening dose should be administered at Sahur (the pre-dawn meal).

For instance, if you normally consume 30 units while getting up and 20 units at night, you should increase it to 30 units during Iftar and 10 units during Sahur during Ramadan.

Split Insulin Therapy

If you’re on split insulin therapy, which includes short-acting and intermediate-acting insulin, you’ll need to make some adjustments. Move your entire morning short-acting dose to Iftar, and your entire lunch short-acting dose to dinner (if you have dinner).

At Sahur, keep half of your dinner short-acting dose and intermediate-acting dose.

Bi-phasic Insulin Therapy

If you’re using bi-phasic insulin, such as BILis 25, BIAsp 30, or BHI 30, along with Metformin, you’ll need to modify your routine during fasting. Take your usual breakfast dose of insulin at Iftar, and Metformin at Sahur.

Should your blood sugar levels rise too high by midday, consider adding insulin at Sahur. This should be half of your regular evening dose.

Bear in mind, that these are general suggestions. Your specific needs may vary based on your blood glucose readings. Always seek advice from your healthcare professional before altering your insulin schedule. It ensures your routine is customized to your unique needs.
