Several reasons motivate people suffering from morbid obesity to resort to bariatric surgery:

• An important study by Dr. Christou has shown that bariatric surgery can reduce the risk of premature death by 89% in morbidly obese patients operated on and lose enough weight, when compared to morbidly obese patients who have not been made.
• Patients who are morbidly obese have much higher rates of type 2 diabetes, hypertension and heart disease than non-obese patients. These health problems are improved or eliminated following a successful weight loss in almost 90% of patients.
• Diets usually do not work long term. Only 3 to 5% of all people trying to lose weight by this method successfully maintain their weight over five years.
• Medical experts have determined that bariatric surgery was the only permanent solution for weight loss. The NIH of the United States has in fact met in 1991 and 1996, a pannel of experts and earned a decisive consensus that bariatric surgery was the best way to lose weight in the morbidly obese, when all other methods have failed for them. That consensus has since been repeated by other experts.
