Diabetes explained

Diabetes is a condition where someone has too much glucose – a type of sugar – in their blood. When people don’t have diabetes their blood sugar levels are controlled by a hormone called insulin that is produced in their pancreas.

If someone has diabetes, they’re either not producing insulin, or the insulin they do produce can’t work properly or there isn’t enough of it. This means that sugar builds up in their blood and can’t get into the cells of their body where it’s used for fuel. Too much sugar in the blood can lead to sight loss, foot ulcers, amputation, kidney failure, stroke and death; these are known as the complications of diabetes.

Type 2 diabetes

Type 2 diabetes develops when the body still makes some insulin but it’s not able to work properly or there isn’t enough. Some people can manage it with a healthy diet, regular physical activity and, if they need to, by losing weight. But the longer someone has Type 2, the more likely it is that they will need medication. About a quarter of people with Type 2 will eventually need to take insulin.

About 90% of people that have diabetes have type 2 and about 3 in 5 cases, type 2 can be prevented or at least delayed by making healthier food and lifestyle choices.
