The risk is high especially in men. At least three in every 100 people in the UK will develop diabetes and 1.8 million people in the UK are thought to have had their diabetes diagnosed (an increase of 400,000 in just eight years). However, it is estimated that there is a "missing million" – people who have diabetes but just don't know it. Men are one-and-a-half times more likely to get diabetes than women. People from Afro-Caribbean or Asian cultures living in the UK are four to five times more likely to develop diabetes than Caucasian members of the population.
