Type 1 diabetes is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy. Diagnosing is often impossible by yourself, and may often feel like you're venturing into a dark unknown. If you have some symptoms, you'll need to consult your physician to help to diagnose and treat diabetes.

Different factors, including genetics and some viruses, may contribute to type 1 diabetes. Although type 1 diabetes usually appears during childhood or adolescence, it can develop in adults. The signs and symptoms of type 1 diabetes often appear quickly and include:
- Increased thirst
- Frequent urination
- Extreme hunger
- Unintended weight loss
- Irritability and other mood changes
- Fatigue and weakness
- Blurred vision
Despite active research, type 1 diabetes still has no cure. Treatment focuses on managing blood sugar levels with insulin, diet and lifestyle to prevent complications. Many people can lead active lives with type 1 diabetes once blood sugars are within range.
