What is Bariatric Surgery?
Bariatric or weight loss surgery is a term that covers all the different surgical procedures used to help patients with weight related problems, lose weight.

Eligible patients are usually identified by their Body Mass Index (BMI) measurement, although other factors may also be taken into account.  Bariatric surgery can cure or greatly improve weight related illnesses like Type 2 diabetes, hypertension and obstructive sleep apnoea, as well as give the patient an improved quality of life.

Procedures fall into three main types:

Malabsorptive - these procedures involve bypassing a section of the small intestine thus reducing the amount of food absorbed into the body.

Restrictive - these procedures involve reducing the size of the stomach, usually by creating a small pouch at the top of the stomach which limits the amount of food that can be eaten.

Malabsorptive/Restrictive Combination - these procedures combine both techniques e.g. gastric bypass surgery in which a small stomach pouch is formed and its outlet connected to part of the small intestine.
