Diabetes is a chronic medical condition in which the body does not produce enough insulin or is unable to use it effectively. Symptoms of diabetes include increased thirst and hunger, frequent urination, fatigue, weight loss, blurred vision, and slow healing of cuts and bruises. Diagnosis of diabetes is made through blood tests that measure the amount of glucose (sugar) in the blood. Treatment for diabetes includes lifestyle changes such as eating a balanced diet, exercising regularly, and maintaining a healthy weight. Medication and insulin therapy may also be necessary to control and manage the disease.
