Enteroendocrine Changes Facilitating Weight Loss Following Gastric Bypass

Obesity is a chronic, progressive and debilitating disease which affects psychological, biological and socials aspects of an individual’s life. As obesity is now globally accepted as an epidemic, increasing number of surgical operations are being performed due to the high rates of failure of the available conventional therapy options. The number of operations performed for the treatment of morbid obesity has increased steadily during the last two decades to an estimated number of nearly 180,000 operations per year in the US [1,2]. The majority of these procedures consist of various modifications of RNYGBP which is accepted as the gold standard procedure for the surgical treatment of morbid obesity [3].
