Does caffeine affect diabetes?

My father has diabetes, and he's always been a big tea drinker. His doctor recently told him to cut down on caffeine, but didn't elaborate much. Does caffeine actually affect diabetes or blood sugar levels?

As a diabetic for ten years, I can tell you that black coffee actually spikes my blood sugar temporarily. This is because caffeine can release stress hormones like adrenaline. If you are having coffee, always check your levels before and after to see how your body reacts.

For mild sugar control, we often use home remedies like methi seeds water in the morning. Caffeine in milk tea with sugar is definitely bad, but plain black coffee might affect everyone differently. If your fasting sugar is consistently high, please consult your doctor.

If your doctor allows, doing a 15-minute brisk walk right after having your morning coffee can help utilize that glucose and prevent any insulin spike. Staying active is the best way to counter any minor metabolic changes caused by caffeine.

Yes, caffeine can sometimes affect insulin sensitivity in some people. It is best to stick to just one small cup a day and avoid adding any sugar or heavy cream to it.

Bro, I noticed my sugar levels go slightly up if I drink too much energy drink or strong coffee during exams. It's basically the caffeine raising your cortisol. Keep it moderate and don't drink it late at night.

Hey, don't stress too much about your morning cup! Just try to avoid adding white sugar or sweet syrups to it. If you really love your tea or coffee, switch to stevia or drink it plain, and you will be completely fine.

I agree with others here. Just monitor your blood glucose levels regularly using a home monitor to see how coffee affects you personally.

I can only share what my endocrinologist told me during my last checkup. He said that while moderate coffee might be good for long-term prevention, acute caffeine intake can actually lower insulin sensitivity. So I have restricted myself to one unsweetened cup.
