Gastric bypass can have a profound impact on Type 2 diabetes. Many people experience improvement or even remission of their diabetes symptoms following the surgery. This happens because gastric bypass surgery can improve the body’s ability to regulate blood sugar levels. Several factors are at play here. First, weight loss itself can improve blood sugar control. Second, bypassing a portion of the small intestine changes hormones in the gut that may influence insulin production and sensitivity. The exact mechanisms are still being studied, but the results are promising. It’s important to note that while gastric bypass surgery can significantly improve diabetes in many patients, it’s not a guaranteed cure and it’s still crucial to follow the guidance of a healthcare provider in managing diabetes.
