Up to 95% of patients with diabetes have type II diabetes. The pancreas produces insulin, but the body is unable to fully use it. Type II diabetes usually develops gradually in adults around the age of 30, but it can also develop in children. In most cases, insulin injections are not absolutely required (unlike Type I where it is imperative as pancreas do not produce any insulin in this type). Type II diabetes can also be managed with only a healthy diet and regular exercise. A prescription medicine is often used to assist the body in better managing sugar levels.
