Today there are many different forms of weight loss surgery performed around the world including that old favorite the Roux-en-Y gastric bypass, the relatively new lap band procedure and the perhaps not quite so well know, but extremely effective, gastric sleeve. Because weight loss surgery is considered by many insurance companies to be an elective medical procedure you often find that you have to pay for it yourself and, for an increasing number of people that means looking overseas for treatment. Medical tourism has grown considerably in recent years and more and more people are choosing exotic destinations such as Thailand for a range of procedures. It is no surprise therefore to find that weight loss surgery, including the gastric sleeve, has now joined the list of those procedures regularly being performed overseas.
