A complete introduction to Type ll Diabetes. Symptoms | Causes | Complications | Prevention


Type ll diabetes is a chronic condition which affects the way the human body metabolizes sugar (glucose) an important source of fuel for the human body.

With type ll diabetes, your body either resists all effects of insulin. A hormone which regulates the movement of sugar into your cells or doesn’t produce enough insulin to maintain the normal glucose levels.

Type ll diabetes mostly used to be known as the adult-onset but nowadays mostly children are being diagnosed with the disorder, probably due to the rise in their childhood obesity. There is no cure for type ll diabetes, but eating well, losing weight, & exercising can help manage the disease. If exercise & diet are not enough to manage your blood sugar well, you may also need insulin therapy or medications.

  • The pancreas secretes insulin into the bloodstream.
