It is true that the entire stomach can be removed. Generally, this is considered a major abdominal surgery
, and is only reserved for patients that have been diagnosed with stomach cancer, in which removal of the stomach is considered necessary as part of the treatment plan. When the stomach is removed completely, the esophagus may need to be directly connected to the first part of the small intestine. Sometimes, smaller portions of the stomach are removed for conditions such as severe ulcers which can cause bleeding
or perforation of the stomach wall. In certain types of weight loss
surgeries, large portions of the stomach may be "bypassed," making the remaining stomach much smaller and helping curb excessive appetites.
