Type 2 diabetes remission: what it means and what the evidence shows

Reviewed by the JForH team · 2026-10-30

Type 2 diabetes remission means your A1C stays below 6.5% at least 3 months after stopping all glucose-lowering medicine, according to a 2021 ADA, EASD and Diabetes UK consensus. It is not a cure, and diabetes can return. In the DiRECT trial, 46% of people in a doctor-supervised weight-loss program were in remission at 1 year and 36% at 2 years; results vary, and you should never stop medicine without your doctor.

What does type 2 diabetes remission mean?

In 2021 an international expert panel convened by the American Diabetes Association, with the European Association for the Study of Diabetes, Diabetes UK and the Endocrine Society, agreed on one definition. Type 2 diabetes is in remission when your HbA1c (A1C) stays below 6.5% when measured at least 3 months after you stop all glucose-lowering medicine.

• If A1C is not reliable for you, the panel allows a fasting glucose below 126 mg/dL, or an estimated A1C below 6.5% calculated from CGM data.
• After weight-loss surgery, remission should be checked at least 3 months after the operation. After diet and lifestyle changes, it should be checked at least 6 months after starting.
• Remission should be confirmed with regular A1C tests, at least once a year.

Is remission the same as a cure?

No. The panel chose the word "remission" on purpose. Diabetes can come back, especially if weight returns. People in remission still need regular A1C checks and the usual screening for eye, kidney, nerve and heart problems, because the risk built up over the years does not disappear.

A normal A1C while you still take diabetes medicine is good control, not remission. That includes metformin, insulin and GLP-1 medicines.

What did the DiRECT trial find?

DiRECT was a large trial run in 49 family practices in Scotland and northern England. It enrolled adults with type 2 diabetes diagnosed in the previous 6 years who were not on insulin and had overweight or obesity. People in the program stopped their diabetes and blood pressure medicines under supervision, followed a low-calorie formula diet (about 825 to 853 calories a day) for 3 to 5 months, then slowly went back to regular food with ongoing support.

The 5-year numbers come from an extension study in which only some people took part, so they are less certain than the earlier results. Of those in remission at 2 years, about 26% were still in remission at 5 years. People who stayed in remission longer had fewer serious medical problems over the 5 years.

How much weight loss is linked to remission?

In DiRECT, the more weight people lost, the more likely remission was. At 12 months, across everyone in the study:

At 2 years, 64% of people who had kept off at least 10 kg (22 lb) were in remission. Keeping the weight off is the hard part: only about 1 in 4 people in the program group had kept off 10 kg at 2 years.

Can a lifestyle program without a formula diet lead to remission?

Sometimes, but less often. In the US Look AHEAD study of about 4,500 adults with type 2 diabetes and overweight, an intensive lifestyle program of diet and physical activity led to partial or complete remission in 11.5% of people in the first year, compared with 2.0% in the comparison group. By year 4 that fell to 7.3%. Only 3.5% stayed in remission for all 4 years. Remission rates were higher, about 15% to 21%, in people who lost more weight, improved fitness more, had diabetes for a shorter time, had a lower A1C at the start or were not using insulin.

Can bariatric surgery put diabetes into remission?

It can, for some people with type 2 diabetes and obesity. In an Italian trial published in The Lancet in 2021, 60 adults with a BMI of 35 or higher were randomly assigned to medicines or to one of two types of weight-loss surgery and followed for 10 years. Remission lasted the whole 10 years in 37.5% of people who had surgery, and in 5.5% of those on medicines (one of whom later had surgery). More than half of those in remission at 2 years saw their diabetes return later, though their glucose stayed well controlled. Surgery carries real risks, and the ADA Standards of Care describe who may be a candidate.

Does a low-carb diet lead to remission?

The evidence is mixed. A 2021 review in The BMJ pooled randomized trials and found that, after 6 months, more people on low-carbohydrate diets had an A1C below 6.5% than people on other diets (about 57% versus 31%). But when the stricter rule was used, A1C below 6.5% while off all diabetes medicine, the difference was small and not statistically clear. Data at 12 months were limited. The ADA says reducing carbohydrates can improve glucose for some adults, and that very-low-carb eating showed its biggest effect in the first 6 months.

Who is most likely to reach remission?

Across these studies, remission was more likely in people who:

• Had type 2 diabetes for a shorter time (DiRECT enrolled people diagnosed within 6 years).
• Were not using insulin.
• Had a lower A1C at the start.
• Lost more weight and kept it off.

Remission is less likely after many years of diabetes or when insulin is already needed, but better glucose, weight and fitness still lower the risk of complications. Results vary from person to person.

Where do GLP-1 medicines fit?

GLP-1 receptor agonists and related medicines lower blood sugar and help many people lose weight. But under the 2021 definition, a normal A1C while you are still taking them is not remission, because remission is judged off all glucose-lowering medicine. When people without diabetes stopped semaglutide in the STEP 1 trial, they regained about two-thirds of the weight they had lost within a year, and most health measures moved back toward where they started. The study authors concluded that ongoing treatment was needed to keep the benefits. Whether to use, stay on or stop these medicines is a decision to make with your doctor.

Is it safe to stop diabetes medicine on your own?

No. Never stop or lower your diabetes medicine without your doctor. In DiRECT, medicines were stopped on day one under medical supervision because a very low-calorie diet plus insulin or a sulfonylurea can cause dangerous low blood sugar. Some medicines, such as blood pressure pills, may also need to be adjusted as weight drops. Your doctor can plan which medicines to reduce, in what order, and how to check your glucose while you do it.

What should you ask your doctor?

• Based on how long I have had diabetes and my medicines, is remission a realistic goal for me?
• How much weight loss would make a difference for me?
• Which of my medicines would need to change if I start a low-calorie or low-carb plan?
• How often should I check my glucose and A1C?
• Can I get support from a dietitian or a structured program?
