Obesity significantly increases the risk of developing diabetes, particularly type 2 diabetes. Excess body fat, especially in the abdominal area, contributes to insulin resistance, where the body's cells become less responsive to insulin. This can lead to higher blood glucose levels, triggering the onset of diabetes. Additionally, obesity is often associated with other risk factors such as high blood pressure and elevated cholesterol levels, further complicating its impact on metabolic health. Managing weight through diet and exercise is crucial for reducing the risk of diabetes and improving overall health outcomes.
