Ramadan 2026: Fasting with Diabetes? Doctors Weigh In on Safety

As Muslims worldwide, including across Nigeria, commenced the Ramadan fast on Wednesday, February 18, 2026, a critical health query resurfaces for millions living with diabetes: Is it safe to fast? Medical experts have weighed in, offering crucial guidance that underscores the importance of individual health status and strict monitoring.

Doctors: Fasting Possible for Some, Not All

Speaking to Tribune, medical professionals affirmed that fasting with diabetes is indeed possible for some patients, contingent on factors like the type of diabetes, the individual's overall health, and, most critically, their level of blood sugar control. However, they issued a stern warning: patients with poorly controlled diabetes or those experiencing serious complications should refrain from fasting.

Diabetes is a chronic condition where the body either doesn't produce enough insulin or can't effectively use the insulin it makes, leading to disrupted blood glucose regulation. Fasting can significantly alter blood sugar levels, raising the risk of complications such as hypoglycaemia (dangerously low blood sugar) or hyperglycaemia (dangerously high blood sugar), especially during extended periods without food or water.

Who Should Avoid Fasting? Expert Advice from Dr. Aliyu Shehu

Dr. Aliyu Shehu of the Federal Teaching Hospital, Birnin Kebbi, clarified that while fasting is generally safe for many diabetic patients, clear contraindications exist. “The contraindications could be a diabetic patient with poorly controlled blood sugar, a diabetic patient who usually experiences hypoglycaemia with symptoms such as restlessness, excessive sweating, dizziness, tremors, or even loss of consciousness,” he explained. He also advised against fasting for patients on insulin injections or those with other serious diabetic complications.

Dr. Shehu noted that patients who manage their diabetes with oral medications taken once or twice daily can often adjust their drug schedule to align with the Sahur (pre-dawn) and Iftar (breaking fast) periods. However, those on insulin must consult their doctors before considering any fast.

Crucially, Dr. Shehu stressed that any diabetic patient experiencing symptoms of hypoglycaemia (dizziness, excessive sweating, restlessness, tremors) or hyperglycaemia (excessive thirst, excessive urination) must immediately break their fast and seek medical attention.

Type of Diabetes Matters: Insights from Dr. Jonas-Attabo Samson

Further elaborating on the matter, Dr. Jonas-Attabo Samson of the Federal Teaching Hospital, Katsina, highlighted the significance of the type of diabetes. “For people with type 1 diabetes mellitus, particularly if they are in need of insulin at multiple times of the day, it’s not recommended to fast,” he stated.

Conversely, for individuals with type 2 diabetes mellitus, fasting can be safer, especially if they do not have pre-existing chronic complications. However, Dr. Samson cautioned that patients with co-existing conditions like kidney disease, heart conditions, or frequent blood sugar fluctuations should also avoid fasting, regardless of their diabetes type.

Practical Guidance for Diabetic Fasting

For those cleared to fast, Dr. Samson recommended continuous glucose monitoring throughout the Ramadan period. He advised incorporating complex carbohydrates into the pre-dawn Sahur meal to provide sustained energy, while the Iftar meal should be lighter than Sahur to prevent sudden spikes in blood sugar. Both experts unanimously urged diabetic patients to assess their glycaemic control thoroughly and seek medical guidance before commencing the fast.

In conclusion, medical professionals reiterate that while the spiritual benefits of Ramadan fasting are profound, the health and safety of individuals, particularly those managing diabetes, must always take precedence. Consultation with a doctor remains the most critical step for any diabetic patient considering fasting.
