What is type 2 diabetes?

Type 2 diabetes is the most common type of diabetes and differs from type 1 in that the body becomes either insulin resistant or produces too little insulin, rather than being completely unable to produce insulin.

There are two main types of diabetes. Type 1 and type 2. Type 2 is mainly affected by behavioural risk factors such as obesity, inactivity, unhealthy diet, alcohol consumption and smoking, but needs environmental triggers to set it off.

What happens in type 2 diabetes?

In type 2 diabetes the body either does not produce enough insulin or becomes insulin resistant, meaning that the body's cells stop reacting properly to insulin. If the blood glucose is not converted into energy by the cells, it accumulates in the blood, which can lead to starvation of the cells, and eventually high blood glucose levels can damage your eyes, kidneys, nerves or your heart. In the worst cases, the body will start finding other sources of energy and will start converting fat and muscle into energy. This can be a very dangerous complication of the diabetes.
