Gastromy refers to surgical procedures that are performed on the stomach. However, there are other terms synonymous with this word that are used to describe similar procedures. These include gastric surgery, stomach surgery, stomach reduction surgery, and bariatric surgery. All these terms describe surgeries that aim at reducing the size of the stomach. Gastric surgery is usually performed on individuals who are obese and need to reduce their weight. Stomach surgery, on the other hand, is used to treat conditions such as stomach cancer. Bariatric surgery is performed to reduce the risk of developing obesity-related complications such as diabetes and heart disease.
