The stomach is the digestive organ in the abdomen that initially processes swallowed food. Food and water is swallowed down the esophagus into the stomach. It then passed into the intestines and ultimately wastes are excreted from the rectum and anus. Various stomach symptoms include stomach pain, acid reflux, delayed digestion, and other digestive symptoms. Stomach disorders include stomach cancer, hypersecretory disorders, stomach ulcers (peptic ulcers), gastritis, gastroparesis, and many other disorders.
