A disease in which one or more raw areas develop in the membranes lining the esophagus, stomach, and duodenum. The affected areas are damaged by strong acids and digestive enzymes secreted by stomach glands. The two main types of peptic ulcer disease are duodenal ulcers and gastric ulcers. Duodenal ulcers occur primarily on the duodenal bulb, which is the first part of the duodenum, the part of the small intestine into which the stomach empties. Gastric ulcers can occur anywhere in the stomach.
Gastric erosion is a gastrointestinal condition characterized by the erosion of the stomach lining caused by the acidic properties present in the digestive juices.
