Hello. My name is Professor Tricia Tan. I'm a consultant in metabolic medicine and endocrinology at Imperial College. My lecture today will be on diabetes, obesity, and the mechanisms of remission of diabetes after bariatric surgery.
To start with, let me say that from now on whenever I mention diabetes, I will be particularly referring to type 2 diabetes, the most common type. The intimate relationship between diabetes and obesity has been clear for the last 50 years. This slide shows the progressive rise in obesity in the United States driven by the availability of cheap, tasty, and high-calorie foods, plus reduced opportunity to expend energy. This has been paralleled by the rise in diabetes' prevalence. The same story is being noted all over the world and UK is no exception.
This graph shows the prevalence of obesity in patients with diabetes. It serves to show that many diabetic patients are obese. Generally speaking, between 30% to 80% of patients with diabetes are obese on the BMI criteria, depending on ethnicity of the population studied. Chinese populations appeared to have a relatively low prevalence of obesity in diabetes by BMI criteria. However, if we'd look at waist circumference as a measure of visceral adiposity, the prevalence is higher. We can therefore say that there is clear relationship between obesity and diabetes, but the strength of this relationship depends on ethnicity of the population you are studying.
