Reversing Diabetes: Fact Or Fiction?

The idea of “reversing diabetes” has gained a lot of attention in recent years, especially with regards to Type 2 diabetes. To understand whether it’s fact or fiction, it’s important to break down what diabetes is and the current medical understanding of it.

Type 1 Diabetes

Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys insulin-producing cells in the pancreas. It typically develops in childhood or adolescence, and currently, there is no cure for it. Insulin therapy is required for life. Reversal of Type 1 diabetes is not currently possible.

Type 2 Diabetes

Type 2 diabetes, on the other hand, is a metabolic condition where the body either becomes resistant to insulin or doesn’t produce enough. It is often linked to lifestyle factors such as diet, exercise, and body weight. Here’s where the idea of “reversal” comes in.

Can Type 2 diabetes be reversed? In some cases, Type 2 diabetes can be put into remission (a term often preferred over “reversed”). This means that the blood sugar levels return to normal without the need for medication, but the underlying risk factors are still there, and the condition could return if lifestyle changes are not maintained. Remission is more likely if the person makes significant lifestyle changes, particularly:

1. Weight loss: Losing a substantial amount of weight (often 10-15% of body weight) has been shown to improve insulin sensitivity and in some cases, put Type 2 diabetes into remission.
2. Diet: Adopting a healthy, balanced diet low in processed foods and high in fiber, fruits, vegetables, and lean proteins can help manage blood sugar levels.
3. Exercise: Regular physical activity helps improve insulin sensitivity and can assist with weight management.
4. Bariatric surgery: For some individuals, weight-loss surgery has led to remission of Type 2 diabetes, particularly for those with severe obesity.

Clinical Evidence

Recent studies have shown that early intervention in Type 2 diabetes, especially within the first few years of diagnosis, increases the chances of remission. The DiRECT trial in the UK found that a significant portion of patients who followed a strict diet and lost weight were able to stop taking medication and had normal blood sugar levels.

However, even with these interventions, diabetes is still considered a chronic condition. The potential for remission doesn’t mean that the disease is “cured.” If lifestyle changes aren’t maintained, blood sugar levels can rise again.
