General surgery is a surgical specialty that focuses on abdominal contents including the esophagus, stomach, small bowel, colon, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. A general surgeon performs a wide range of abdominal surgeries for many forms of intestinal and abdominal wall neoplasms, gallbladder disease, and gastric and pancreatic disease. They follow the patient through critical care and surgical recovery all the way to outpatient care.

Bariatric surgery (or weight loss surgery) includes a variety of procedures performed on people who are obese. Long-term weight loss through Standard of Care procedures (Roux en Y Bypass, Sleeve Gastrectomy, and Biliopancreatic Diversion with Duodenal Switch) is largely achieved by altering gut hormone levels that are responsible for hunger and satiety, thereby leading to a new hormonal weight set point. A doctor who specializes in this type of surgery is known as a bariatric surgeon.
