About Diabetes
Diabetes is a lifelong condition that causes a person's blood sugar level to become too high.
There are 2 main types of diabetes:
Type 1 diabetes
Where the body's immune system attacks and destroys the cells that produce insulin
Type 2 diabetes
Where the body does not produce enough insulin, or the body's cells do not react to insulin
Type 2 diabetes is far more common than type 1. In the UK, around 90% of all adults with diabetes have type 2.
During pregnancy, some women have such high levels of blood glucose that their body is unable to produce enough insulin to absorb it all. This is known as gestational diabetes.
Symptoms of Diabetes
Visit your GP as soon as possible if you experience the main symptoms of diabetes, which include:
- feeling very thirsty
- peeing more frequently than usual, particularly at night
- feeling very tired
- weight loss and loss of muscle bulk
- itching around the penis or vagina, or frequent episodes of thrush
- cuts or wounds that heal slowly
- blurred vision
Type 1 diabetes can develop quickly over weeks or even days.
Many people have type 2 diabetes for years without realising because the early symptoms tend to be general.
