Obesity surgery is the most effective treatment for individuals with chronic weight problems who have been unable to achieve and maintain weight loss by other means. Weight loss surgery reduces health risks, improves mobility, restores self-confidence and self-esteem and improves long-term survival. In experienced hands, it is a remarkably safe form of obesity treatment. The Private Healthcare UK Guide to obesity and obesity surgery has been provided by Dr David Ashton who is widely recognised as one of the UK’s leading authorities on all aspects of weight loss and management of the post surgery patient. Dr Ashton is Medical Director of Healthier Weight the UK’s most comprehensive provider of weight management and obesity surgery programmes.

What types of obesity surgery are there?
The surgical treatment of obesity has been transformed during the last decade or so, largely due to developments in laparoscopic (keyhole) techniques and anaesthetics. Two types of surgical procedures used to promote weight loss are:
Restrictive surgery
During these procedures the stomach is made smaller so that it holds less food, making you feel full with smaller portions. Because you can only eat small quantities, your calorie intake falls and you lose weight. Restrictive procedures do not interfere with normal digestion and absorption of nutrients.
Malabsorptive surgery
This approach changes the body’s ability to absorb calories from food. By re-routing food in such a way as to exclude (bypass) a section of the small bowel (intestine), much of the calories and nutrients pass through without being absorbed. Again, fewer absorbed calories means weight loss.
Most modern surgical treatments for obesity involve pure restriction or a combination of restriction and malabsorption. The two most commonly performed operations for obesity are:
1. Laparoscopic adjustable gastric banding (LAGB) also known as lap banding/gastric banding
and
2. Gastric bypass ( combining both restrictive and malabsorptive elements)
Gastric banding is a purely restrictive procedure whilst gastric bypass combines restriction with a small malabsorptive component. Other less commonly performed procedures include biliopancreatic diversion (BPD), duodenal switch (BPD/DS) and variants.
A summary of the main benefits and risks of these two procedures is shown below:
