General surgery is a surgical specialty that focuses on alimentary canal and abdominal contents including the esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. General surgeons also deal with diseases involving the skin, breast, soft tissue, trauma, peripheral artery disease and hernias and perform endoscopic as such as gastroscopy, colonoscopy and laparoscopic procedures.
Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch, where the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP). Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
The duodenal switch (DS) procedure, also known as a gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect.

Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, along the greater curvature, which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana. Weight loss is affected not only through the reduction of the organ's size, but by the removal of the portion of it that produces ghrelin, the hormone that stimulates appetite. Patients can lose 50-70 percent of excess weight over the course of the two years that follow the surgery. The procedure is irreversible, though in some uncommon cases, patients can regain the lost weight, via resumption of poor dietary habits, or dilation of the stomach over time, which can require gastric sleeve revision surgery to either repair the sleeve or convert it to another type of weight loss method that may produce better results, such as a gastric bypass or duodenal switch.
Bariatric surgery is a surgical procedure used to manage obesity and obesity-related conditions. Long term weight loss with bariatric surgery may be achieved through alteration of gut hormones, physical reduction of stomach size, reduction of nutrient absorption, or a combination of these. Standard of care procedures include Roux en-Y bypass, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch, from which weight loss is largely achieved by altering gut hormone levels responsible for hunger and satiety, leading to a new hormonal weight set point.
The American Society for Metabolic & Bariatric Surgery (ASMBS) is a non-profit medical organization dedicated to metabolic and bariatric surgery, and obesity-related diseases and conditions. It was established in 1983.
Revision weight loss surgery is a surgical procedure that is performed on patients who have already undergone a form of bariatric surgery, and have either had complications from such surgery or have not achieved significant weight loss results from the initial surgery. Procedures are usually performed laparoscopically, though open surgery may be required if prior bariatric surgery has resulted in extensive scarring.

In medicine, endoscopic sleeve gastroplasty (ESG) is a minimally-invasive, non-surgical (incisionless), endoscopic weight loss procedure that is part of the field of endoscopic bariatric therapies. To perform ESG, a physician sutures a patient’s stomach into a narrower, smaller tube-like configuration. The result is a more restricted stomach that forces patients to feel fuller sooner, eating fewer calories, which facilitates weight loss.

Edward Eaton Mason was an American surgeon, professor, and medical researcher who specialized in obesity surgery. He is known for developing restrictive gastric surgery for morbidly obese patients. Mason introduced the first gastric bypass surgery in 1966 and was the inventor of the first vertical banded gastroplasty surgery in 1980.
Stomach reduction surgery, also known as bariatric surgery, is a medical procedure aimed at facilitating weight loss by reducing the size of the stomach, thereby limiting food intake and promoting satiety with smaller portions. It is frequently used for cases where traditional weight loss approaches, consisting of diet and physical activity, have proven insufficient, or when obesity already significantly affects well-being and general health.
