Hello, my name is John Wilding. I'm professor of medicine at the University of Liverpool and a consultant physician at Aintree Hospitals in Liverpool in the UK. And I have an interest in treatment of obesity, particularly, with lifestyle and also with bariatric surgery.

We all know that the prevalence of obesity has been steadily increasing in England as well as around the world over the past 20 to 30 years, as is shown in this slide here. And although we're beginning to see a leveling off of this, it is now the fact that a quarter of the population are obese and this results in very significant health consequences for the individuals concerned.

The consequences of obesity are illustrated in this slide. These can be broadly thought of as those that result in the mechanical consequences of carrying excess body weight and these include problems such as joint pain, osteoarthritis, breathlessness, the development of obstructive sleep apnea, and for women who become pregnant, the increased risk during childbirth is significant. And indeed, in the United Kingdom, the greatest reason for maternal mortality is in fact, obesity. Many people also focus on the metabolic consequences of obesity and the number one consequence here is, of course, type 2 diabetes, which is also associated with an increased risk of cardiovascular disease. Non-alcoholic fatty liver disease, polycystic ovarian syndrome, and infertility, are also more common in the obese and it is well recognized that many cancers, particularly, those that are hormone-dependent such as breast cancer, endometrial cancer and prostrate cancer are also more common in obesity. The psychosocial consequences for obesity include depression, low income, and body image dysphoria. It's important to remember that these consequences of obesity are not independent and, in fact, interact with each other to create cycles of causation. And in many obese individuals, there are several comorbidities present in the same individual.
