Diabetes is a disease that causes high glucose (a kind of sugar) in your blood. It happens when your body can not make or use enough insulin. While there is no cure, you can still live well with diabetes if you manage it well. 


What happens when you have diabetes

When you eat foods containing carbohydrates (such as bread, cereal and fruit), your body turns them into glucose. A hormone called insulin then moves the glucose out of your blood and into your muscle and fat cells. Insulin is made in your pancreas, which is a gland right below your stomach.

  • You get type 1 diabetes if your pancreas does not make enough insulin.
  • You get type 2 diabetes if your body cannot use the insulin it makes properly.

Some women get another kind of diabetes while they are pregnant called gestational diabetes.

If you have too much glucose in your blood, you may have a range of symptoms including feeling thirsty, needing to wee a lot and feeling tired. Some people with type 2 diabetes have no symptoms.

Managing diabetes

Diabetes is a serious condition that needs to be managed. Long term, it can lead to complications in several parts of your body including your eyes, feet and kidneys. You can reduce your risk of complications by carefully managing your diabetes.

Eating well and being physically active are important in preventing prediabetes and type 2 diabetes, and for treating all diabetes.
