Implantation of a duodenal–jejunal bypass sleeve for managing obesity

The condition

Obesity is defined as a body mass index (BMI) of 30 kg/m² or more. Obesity increases the risk of other conditions such as type 2 diabetes. Changes to diet and exercise usually help to reduce weight, and sometimes drugs are offered. Surgery to help weight loss (known as bariatric surgery) is sometimes considered if the person is unable to lose enough weight.
