There are two main types of diabetes: type 1 and type 2. Type 2 is the most common and is often linked to being overweight. That means there are steps you can take to reduce your risk of developing it.
Type 1 diabetes is not linked to being overweight. Instead, the cells that produce insulin in the body are damaged for reasons that aren't yet fully understood. There are no lifestyle changes that can lower your risk of type 1 diabetes.
However, around 90% of people diagnosed with the condition have type 2 diabetes. If you maintain a healthy weight, you can reduce your risk of developing the condition.
If you think that you may already have symptoms of diabetes, see your GP.
