Diabetes is a disorder that comes from your lifestyle choices. Diabetes when your body can't produce any or enough insulin causing the glucose levels in your blood to rise. In type 1 diabetes, the body no longer makes insulin because the body's own immune system has attacked and destroyed the cells where insulin is made. In type 2 diabetes, the body either doesn't make enough insulin or can't use its own insulin as well as it should. The risk of having type 2 diabetes increases as a person gets older. Effects of diabetes are damage to the large blood vessels of the heart, brain and legs, damage to the small blood vessels, causing problems in the eyes, kidneys, feet and nerves. Diabetes are not curable but they are treatable. You can treat diabetes by lowering you r blood sugar levels.
