The leading cause of type 2 diabetes is insulin resistance. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by facilitating the absorption of glucose into cells. In people with insulin resistance, the body's cells become less responsive to insulin, which means that glucose remains in the bloodstream instead of being absorbed into the cells. Over time, this leads to high blood sugar levels, which can cause damage to various organs and tissues in the body.
Insulin resistance is often associated with lifestyle factors such as a sedentary lifestyle, a diet high in processed and sugary foods, and obesity. Genetics and family history can also play a role in the development of insulin resistance and type 2 diabetes. While there is no cure for type 2 diabetes, it can often be managed through lifestyle changes such as regular exercise, a healthy diet, and medication if necessary.
