Diabetes is one of the oldest and most mysterious diseases known to civilized society. Other symptoms are extreme thirst, hunger, weakness, and weight loss. Diabetes can lead to blindness and kidney failure. It can also cause the loss of the lower limbs.
Onset depends on the type of diabetes a patient has.
Probably another 10 million have the disease but don't know it. Some people may go for 5-6 years before their disease is discovered. There are three population groups in the United States that are most affected by diabetes. Probably both genetics and diet. While there is no known cure, diabetes in most people can be controlled by diet, exercise and medications.
