Obesity is associated with diabetes, heart disease, high blood pressure, some types of cancer and other medical problems. Mortality in men with 50% excess weight is double and 5 times more if they are diabetic.

In women, mortality increases by double the original and 8 times more if they are diabetic. The Bariatric surgery is the term used to refer to operations that help promote weight loss. Bariatric surgery procedures are only advised for people with severe obesity ie a body mass index greater than 40 or greater than 35 if they have associated diseases.

Bariatric Surgery

People considering bariatric surgery should consider the risks and possible benefits with their doctor. Bariatric surgery has associated risks and long-term consequences, and should only be considered as part of an approach in treating their obesity. Most bariatric surgeons believe that operations have better results when they help promote lifelong changes in behaviour and nutrition. To avoid complications that may represent a risk in the patient’s life, it is essential to continue a long-term follow up with doctors who are experienced in dealing with patients undergoing these procedures, as well as to oversee a life supplement of vitamins.

Body Mass Index

The BMI is calculated based on a person’s height and weight: weight in kilograms divided by the square of their height in meters. A BMI of 25 or more is considered overweight; 30 or more, obesity; and 40 or more, morbid obesity. Bariatric surgery can be offered to patients with severe obesity when medical treatments, including changes in lifestyle, such as healthy eating and regular exercise, have not been effective.
