Type 1 diabetes (previously known as insulin-dependent, juvenile or childhood-onset) is characterized by deficient insulin production and requires daily administration of insulin.

Type 1 diabetes (sometimes called insulin-dependent, juvenile or childhood-onset diabetes) occurs when the pancreas does not produce enough insulin, a hormone that regulates blood sugar.

Type 1 diabetes, also known as juvenile diabetes, is a disease that often develops early in life and is separate from Type 2 diabetes, which often stems from obesity.
