People wearing trousers with large waist sizes should be worried about their increased risk to Type 2 diabetes.
Research presented at the Diabetes UK Annual Professional Conference (29 to 31 March) in Birmingham, suggested that large waistlines are more of a risk factor for Type 2 diabetes than weight.
Diabetes UK recommends that men and women should aim to have waists of less than 94cm and 80cm respectively.
Natasha Marsland, Care Advisor at Diabetes UK, said: "Fat around your belly is directly linked to Type 2 diabetes and heart disease. It's time men and women started worrying about their waists."
