Diabetes is a lifelong condition that causes a person's blood sugar level to become too high.  The amount of sugar in your blood is controlled by a hormone called insulin, which is produced by the pancreas (a gland behind the stomach).  When food is digested and enters your bloodstream, insulin moves glucose out of the blood and into cells, where it's broken down to produce energy.

However, if you have diabetes, your body is unable to break glucose down into energy, either because there’s not enough insulin to move the glucose or the insulin produced doesn't work properly.

Although there are no lifestyle changes you can make to lower your risk of Type 1 diabetes, Type 2 diabetes is often linked to being overweight or inactive and is the most common type in the UK.

Diabetes can also cause other conditions, such as sight loss, kidney failure, heart attacks or stroke and, every year, around 22,000 people with diabetes die early.

The types of diabetes

Type 1 diabetes: Where the body's immune system attacks and destroys the cells that produce insulin

If your body can't produce enough insulin to control your blood glucose, you’ll need daily injections of insulin to keep your blood glucose levels under control.  It can take time to get used to managing Type 1 diabetes, but it won’t prevent you from still doing the things you enjoy. 

Type 2 diabetes: Where the body doesn't produce enough insulin or the body's cells don't react to insulin

Type 2 diabetes is far more common than Type 1 and is often linked to being overweight or inactive or having a family history diabetes.  If you have Type 2 diabetes or are at risk of developing it, you may need to make changes to your lifestyle, including changing your diet and exercise levels.
