Diabetes
People who have diabetes cannot successfully control their blood glucose levels. In type 1 diabetes, the pancreas cells in the body either produce little or no insulin.

Timeline

- We do not know what causes type 1 diabetes, but we think that the body's immune system attacks the pancreas cells.

Symptoms

- More frequent urination.
- Feeling of tiredness and fatigue.
- Weight loss.
- Blurred vision.
- Slow healing of wounds.

Treatment
- The main treatment is to inject insulin when blood glucose levels rise too high.
- Sufferers can also:
- Control their carbohydrate intake to prevent their blood glucose levels rising too high.
