Can Type 2 Diabetes Be Reversed? Here’s What Science Says
Share
Type 2 diabetes has long been seen as a lifelong condition. But recent research is changing that view. Experts now believe that type 2 diabetes remission is possible for many people. This doesn’t mean a “cure” but rather having healthy blood sugar levels without the need for diabetes medications.
What Is Remission?
Remission in type 2 diabetes means keeping your blood sugar (HbA1c) below 6.5% for at least three months without using glucose-lowering medicines. If you still take diabetes drugs, even for other reasons like weight or heart issues, it’s not considered remission.
Why Remission Matters
Achieving remission can:
- Lower your risk of heart and kidney disease
- Reduce or stop medication use
- Improve energy, mood, and overall quality of life
Even more importantly, remission may preserve the cells in your pancreas that help control blood sugar.
How Can You Achieve Remission?
There are several ways remission can be achieved. Let’s break them down.
1. Weight Loss Through Diet and Lifestyle
Losing 10% to 15% of your body weight—especially early after diagnosis—can lead to remission. In studies like the DiRECT and DIADEM-I trials, many people who followed low-calorie meal plans and stayed physically active were able to stop diabetes medications.
Key strategies include:
- Eating fewer calories (around 800 to 850 a day during meal replacement phases)
- Gradually reintroducing healthy foods
- Walking daily and staying active
Quick and significant weight loss helps reduce fat around the liver and pancreas, which improves insulin function.
2. New Diabetes Medications
Some newer drugs not only control blood sugar but also help people lose weight. These include:
- GLP-1 receptor agonists (like semaglutide)
- SGLT2 inhibitors
- Dual-action drugs like tirzepatide
These medications can help lower weight and blood sugar, and some people go into remission while using them. However, stopping the medication often leads to weight regain and rising blood sugar. So this might be called “pharmacological remission,” not true remission.
3. Metabolic Surgery
Weight loss surgery, like gastric bypass or sleeve gastrectomy, is currently the most effective method to achieve long-term remission. Surgery works not just by reducing the size of the stomach but also by changing hormones that control hunger and insulin. Some surgeries can lead to remission in over 60% of patients.
However, surgery is not for everyone. It’s usually recommended for people with a BMI over 35 and may have risks or side effects. But for many, the benefits—including reduced risk of heart disease and sleep apnea—can be life-changing.
Who Has the Best Chance at Remission?
You’re more likely to achieve and maintain remission if you:
- Are younger
- Were recently diagnosed
- Are not on insulin
- Have fewer medications
- Can lose a larger percentage of body weight
Doctors are now using tools like the DiaRem score and even gut bacteria profiles to predict who will respond best to treatment.
Final Thoughts
Type 2 diabetes remission is real and possible, especially if caught early and managed with weight loss, new medications, or surgery. It takes effort, commitment, and support—but the rewards are well worth it.
If you or a loved one is living with type 2 diabetes, talk to your doctor about whether remission is a realistic goal for you. The dream is no longer out of reach.
