Diabetes of the Brain and Body
TYPE 1 Only about 5 percent of people with diabetes have type 1, which is typically diagnosed in children and young adults. The body attacks the insulin-producing cells in the pancreas, making it unable to regulate blood sugar. These patients need insulin therapy to survive.
TYPE 2 The most common type; either the pancreas does not produce enough insulin, or muscle, liver, and fat cells ignore insulin, leading to high blood sugar levels and increased risk of heart disease, stroke, blindness, nerve damage, and amputation.
TYPE 3 This controversial category refers to Alzheimer’s disease, which may arise when brain tissue becomes insulin resistant. It is like type 2 but primarily concerns the brain.
