Diabetes is a disease where the body cannot properly regulate blood sugar levels. There are two main types of diabetes: type 1 where the body does not produce insulin and type 2 where the body does not properly use insulin. Risk factors for diabetes include family history, age, and obesity. Complications from uncontrolled diabetes can include damage to organs like the eyes, kidneys, and nerves. Treatment involves monitoring blood sugar levels, diet, exercise, and medication.
