This is a very common and very important question.
When sugars become normal after weight loss and lifestyle changes, we usually call it diabetes remission, not permanent reversal.

Let me explain this simply.
Your weight loss and lifestyle changes have reduced insulin resistance. Because of that, your sugars are controlled, sometimes even without high doses of medicines. This is a success, but it does not mean diabetes has disappeared from the body.
In medicine, we do not use the word “cure” for type 2 diabetes.
Here is what you should clearly understand:
- Remission means sugars are normal for now.
- Reversal sounds permanent, but medicine cannot guarantee that.
- Diabetes can come back if weight increases or lifestyle slips.
That is why you should never stop diabetes medicines on your own.
Only your doctor can decide:
- Whether the dose can be reduced.
- Whether a medicine can be stopped.
- Whether you can be observed without medicines.
Even when medicines are stopped by a doctor, monitoring must continue.
What you should do practically:
- Continue the same lifestyle that helped you lose weight.
- Check HbA1c every 3 to 6 months.
- If HbA1c moves back into prediabetes or diabetes range, medicines may be needed again.
Think of diabetes like driving on a highway. Even if the road is clear now, you still need to keep your hands on the steering wheel. You cannot relax completely.
So yes, your effort has worked. But no, you should not stop medicines unless your doctor advises it. Remission needs maintenance, not overconfidence.
