Blood Sugar Around 250 After Iftar During Ramadan – Should I Be Concerned?

Quick Answer

Answer by Dr. Albana Greca, MD, MMedSc

Hello Musa,

Yes, I would pay attention to this pattern. Your glucose before Iftar looks quite reasonable, but the large rise after your evening meal suggests that your body is having difficulty handling the amount of glucose entering your bloodstream after eating.

What Do Your Readings Mean?

Your readings become easier to understand when we compare them with common glucose targets.

For many nonpregnant adults with diabetes, a common target is 80–130 mg/dL (4.4–7.2 mmol/L) before meals and below 180 mg/dL (10.0 mmol/L) after meals. You can see more examples in our guide to good blood sugar levels.

Why Does Your Glucose Jump After Iftar?

After many hours without food, it can be tempting to eat a very large meal at Iftar. If that meal contains large portions of rice, bread, potatoes, sweets, dates, sweet drinks, desserts, or other carbohydrate-rich foods, glucose can rise quickly.

The problem is not Ramadan fasting alone. The amount and type of food eaten when the fast is broken can have a major effect on your glucose. Your diabetes medication timing may also influence the evening rise.

A reading around 250 mg/dL two hours after eating is considerably higher than the usual target. Our page about blood sugar after eating explains why repeated post-meal highs are important even when fasting readings look good.

How Can You Reduce the Iftar Spike?

Instead of breaking the fast with one very large meal, I would suggest:

• Keep the Iftar portion moderate.


• Limit sugary drinks, juice, desserts, and large portions of sweets.


• Reduce large portions of white rice, white bread, and other refined carbohydrates.


• Include vegetables, protein, beans, and high-fiber foods.


• Eat slowly rather than consuming a large amount of food quickly.


• Drink enough water between Iftar and Suhoor.


• If your doctor says it is safe, light walking after Iftar may help reduce the post-meal rise.

You do not need to avoid carbohydrates completely. The goal is to control the portion and combine carbohydrates with protein, vegetables, and fiber so glucose rises more gradually.

What About Your Diabetes Medication?

Ramadan changes the timing of meals, so diabetes medication sometimes needs to be adjusted. The correct change depends on which tablets or insulin you use.

Do not skip, double, move, or change your diabetes medication on your own. Speak with your doctor about the appropriate timing during Ramadan, especially if your post-Iftar glucose repeatedly reaches 250 mg/dL or higher.

Continue Checking During the Fast

I would monitor your glucose at different times rather than checking only before and after Iftar. Useful times include before Suhoor, during the fasting day, just before Iftar, and about 1–2 hours after starting Iftar.

Keeping a record of what you eat alongside these readings can help you identify which meals cause the largest rise.

When Should You Break the Fast?

Ramadan diabetes guidelines advise breaking the fast when glucose becomes dangerously low or high.

You should also stop fasting if you develop significant dizziness, confusion, severe weakness, dehydration, vomiting, or symptoms of very low or very high blood sugar. Our guide to low blood sugar while fasting explains why hypoglycemia should be treated promptly.

The Bottom Line

Musa, your glucose of 108–125 mg/dL (6.0–6.9 mmol/L) before Iftar is generally satisfactory for many adults with diabetes. The bigger concern is the rise to around 250 mg/dL (13.9 mmol/L) after your evening meal.

Try reducing the size and carbohydrate load of Iftar, continue monitoring your glucose, stay well hydrated between sunset and dawn, and ask your doctor to review your medication timing if these high post-meal readings continue.
