Type 1 diabetes is often referred to as insulin-dependent diabetes. It is also sometimes known as juvenile diabetes or early-onset diabetes because it often develops before the age of 40, usually during the teenage years.
In type 1 diabetes, the pancreas (a small gland behind the stomach) does not produce any insulin. Insulin is a hormone that regulates blood glucose levels. If the amount of glucose in the blood is too high, it can seriously damage the body’s organs.
If you have type 1 diabetes, you will need to take insulin injections for life. You must also make sure that your blood glucose levels stay balanced by eating a healthy diet, taking regular exercise and having regular blood tests.
