Type 2 diabetes can go into remission, meaning your blood sugar returns to normal levels without medication. This isn’t guaranteed for everyone, but a significant number of people achieve it through substantial weight loss, dietary changes, or surgery. Type 1 diabetes, which involves the immune system destroying insulin-producing cells, cannot currently be reversed. This article focuses primarily on type 2, since that’s what most people searching this phrase are living with.
What “Getting Rid of” Diabetes Actually Means
Doctors use the word “remission” rather than “cure” for a reason. The American Diabetes Association defines remission as maintaining an HbA1c below 6.5% for at least three months without taking any diabetes medication. That’s the same threshold used to diagnose diabetes in the first place, so remission essentially means your blood sugar no longer meets the criteria for the disease.
But remission isn’t permanent in every case. A large retrospective study tracking over 16,000 adults who achieved remission found that about 37% of them relapsed within three years. The underlying tendency toward insulin resistance doesn’t disappear entirely, which is why ongoing monitoring matters even after your numbers normalize. Think of it less like flipping a switch off and more like pushing a condition into the background, where it can stay quiet for years or even decades if you maintain the changes that got you there.
How Much Weight Loss It Takes
Weight loss is the single most powerful lever for putting type 2 diabetes into remission, and the amount matters. In a clinical trial that put participants on a very low-calorie diet (600 to 800 calories per day for three months), people who had been diagnosed within the past four years and lost an average of about 15 kilograms (33 pounds) achieved remission rates of 82%. That’s a striking number. Even people who had lived with diabetes for eight years or longer hit a 50% remission rate with similar weight loss.
The mechanism behind this is straightforward. Excess fat, particularly around the liver and pancreas, impairs your body’s ability to produce and respond to insulin. Losing enough weight reduces that fat, allowing the pancreas to function more effectively again. You don’t necessarily need to reach a “normal” BMI. What matters most is losing enough to relieve the metabolic stress on your organs.
Why Timing Matters
The longer you’ve had type 2 diabetes, the harder remission becomes. Years of elevated blood sugar gradually exhaust the insulin-producing beta cells in your pancreas. In the trial mentioned above, participants diagnosed within four years had remission rates roughly 32 percentage points higher than those diagnosed eight or more years ago, despite losing nearly the same amount of weight. Fasting blood sugar levels and a blood marker called C-peptide (which reflects how much insulin your pancreas still makes) were among the strongest predictors of success.
This doesn’t mean remission is impossible after a long diagnosis. Half of the longer-duration group still achieved it. But if remission is your goal, acting sooner gives you a significantly better chance.
Low-Carb Diets and Remission
Cutting carbohydrates is one of the most studied dietary strategies for diabetes remission. A systematic review published in The BMJ pooled data from randomized trials and found that at six months, 57% of people on low-carb diets achieved an HbA1c below 6.5%, compared with 31% on control diets. That’s a meaningful difference.
The picture gets more complicated when you tighten the definition. When remission required both normal blood sugar and no diabetes medication, the advantage of low-carb diets shrank considerably. By 12 months, the benefit was modest and statistically uncertain. This suggests that low-carb eating reliably improves blood sugar control, but the full package of remission (off all meds, sustained over time) depends on other factors too, especially total weight loss.
One important detail: people who were already using insulin saw much smaller benefits from low-carb diets than those who weren’t. For patients not on insulin, the results were dramatic. Only two people needed to follow a low-carb diet for one to achieve an HbA1c below 6.5%. For those on insulin, the numbers were far less favorable. This likely reflects the degree of pancreatic decline: if your body still produces a reasonable amount of insulin, reducing the carbohydrate load it has to handle can tip the balance back toward normal.
Bariatric Surgery
For people with obesity and type 2 diabetes who haven’t achieved remission through diet alone, bariatric surgery offers the highest remission rates of any intervention. Gastric bypass, in particular, produces results that go well beyond what weight loss alone would predict. At five years of follow-up, 75% of gastric bypass patients maintained diabetes remission. Sleeve gastrectomy, a simpler procedure, achieved 34.8% remission at the same timepoint.
The difference is stark. The odds of diabetes returning over five years were 5.5 times higher with sleeve gastrectomy compared to gastric bypass, even after adjusting for weight-related factors. Gastric bypass appears to trigger hormonal changes in the gut that improve blood sugar regulation independently of weight loss, which is why some patients see their blood sugar normalize within days of surgery, before they’ve lost significant weight.
Surgery isn’t a casual decision, and it comes with its own risks and lifelong dietary requirements. But for people with a BMI over 35 and poorly controlled diabetes, it’s one of the most effective options available.
What About Type 1 Diabetes?
Type 1 diabetes is a fundamentally different disease. The immune system destroys the cells that make insulin, and no amount of weight loss or dietary change can reverse that. There is currently no cure.
There are, however, treatments at various stages of development. Teplizumab, an immunotherapy drug, is FDA-approved to delay the onset of type 1 diabetes in people aged eight and older who are in the early stages of the disease. It doesn’t reverse or cure it; it buys time. Stem cell therapies that could potentially replace destroyed insulin-producing cells are in early proof-of-concept stages and are years away from broad use. Pancreas transplantation can achieve insulin independence, but it’s reserved for patients who already need a kidney transplant and are therefore already on immunosuppression drugs.
If you have type 1 diabetes, the honest answer is that “getting rid of it” isn’t possible right now. Management with insulin remains the standard of care.
Keeping Diabetes in Remission
Achieving remission is only half the challenge. The 37% relapse rate within three years tells you that maintaining it requires sustained effort. The factors that drove your diabetes in the first place, including genetics, insulin resistance, and metabolic tendencies, don’t vanish. Weight regain is the most common trigger for relapse.
What works for maintenance looks a lot like what works for getting there: regular physical activity, a dietary pattern you can actually sustain long-term (whether that’s low-carb, calorie-controlled, or Mediterranean-style), and consistent monitoring of your HbA1c. Most guidelines recommend checking at least once a year even after remission, since blood sugar can creep back up without obvious symptoms. The earlier you catch a rise, the easier it is to course-correct before you’re back on medication.
