There is need for more research in the field of obesity. Until a time when a less invasive, effective, nonsurgical treatment is available, surgery offers the only long-term control of obesity.

Obesity is a hereditary disease.
The exact method of genetic transmission is not known. The expression of obesity varies with social, environmental, cultural, economic, and psychological influences. Rarely is obesity due to an eating disorder. It is highly probable that the obese person with eating disorders has the disorder as a result of the frustration or associated problems of obesity. Obesity is definitely not caused by a lack of willpower.
