What is Bariatric Surgery?

“Bariatric surgery” is a surgery done for weight loss purpose. This term is from a Greek word “baros” meaning “weight”. The procedure evolved out of ulcer/cancer operation which involved the removal of part of the stomach or small intestine. Spontaneous weight loss seen in these patients, gave birth to the idea of similar surgery to treat morbid obesity. Thereafter after certain modifications, this surgical option in treatment of morbid obesity gradually established as a successful one!unt mollit anim id est laborum.

Bariatric surgery has proved to be one of the most effective treatments for achieving significant and sustained long-term weight loss in morbidly obese patients. It causes weight loss through substantial decline of hunger and increased satiety. Recently the understanding of neuro endocrine regulation of food intake and weight gain, especially regarding the role of gut hormones, has significantly increased. The changes in these hormones following bariatric surgery can partly explain the mechanism behind weight loss achieved through these procedures.

Surgical treatment of obesity has evolved over the last century, and is developed a satisfactory stage as a result of constant study, innovation and revisions of surgical procedures.
