Some people with diabetes are relatively obese and some are exceptionally thin. The reason why this happens is mainly due to the different pathogenesis of diabetes. Because insulin itself has a role in promoting protein and fat synthesis, patients who are particularly insulin deficient will show a lean body type, which is clinically known as type 1 diabetes, also called insulin-dependent diabetes. Obese patients are obese because of the presence of insulin resistance, that is, the amount of insulin secretion can be. However, due to reduced effectiveness, diabetes can also occur due to increased blood glucose. These patients are overweight or obese because insulin levels are significantly higher and also promote the synthesis of protein and fat. Therefore, whether a diabetic patient is obese or wasted varies according to the blood sugar level and the function of the islets.
