Diabetes is a disease in which the body is unable to properly use insulin to process the sugar in the blood. Type 1 diabetes is when the pancreas stops making insulin altogether. Type 2 diabetes occurs when insulin is produced by the body, but the body is unable to use the insulin made or does not produce enough insulin. Symptoms of diabetes include frequent urination, excessive thirst, extreme hunger, weight loss, fatigue, irritability and blurred vision. Diabetes can be treated by managing the diet, using insulin, medication, weight loss, physical therapies, acupuncture, biofeedback, and herbal medicine.
