Type 2 diabetes is the most common form of diabetes, affecting around 90% of all people with the condition. It develops when the body becomes resistant to insulin or stops producing enough of it, causing blood glucose to rise.
Most people are diagnosed in adulthood, often after a routine blood test. Many have lived with raised glucose for years before symptoms appear.
