What is a 'normal' Body Mass Index (BMI) and what are the health implications of being over the normal range? In this section there are articles from a surgeon who specialises in obesity management, a dietician and a senior oncological gynaecologist. There are important implications in having a high BMI, for example, obesity is linked to endometrial cancer, with obese women three times as likely to get this disease as women who have a body weight in the healthy range, not to mention diabetes, high blood pressure, heart disease and high cholesterol, all of which are related to obesity. Chances of developing these conditions can be dramatically cut by sensibly reducing weight.
