Type 2 diabetes is a long-term metabolic disorder where the body produces insulin, but the insulin cannot perform its function because the body resists it. Insulin is necessary for the body to be able to break down sugar as a source of energy. The result of insulin resistance is an excessive buildup of sugar in your blood.
Patients who have had weight loss surgery have less insulin resistance. Their risk for metabolic syndrome, high blood pressure, and high amount of fats in the blood also decreases.
A recent meta-analysis research study shows 76.8% of patients who had weight loss surgery had 100% cure of type 2 diabetes, and 86% had improvement in their diabetes control. Many patients with type 2 diabetes have demonstrated little or no need to take diabetes medication or insulin after weight loss surgery. These studies demonstrate that complete remission of type 2 diabetes is possible with some patients who have successfully lost a significant amount of excess weight with bariatric surgery.
