Peptic Ulcer
There are three types of peptic ulcer: gastric ulcer, esophageal ulcer, and duodenal ulcer. A peptic ulcer is a sore along the stomach lining, esophagus, or small intestine with symptoms including cramps, heartburn, nausea, and vomiting. Duodenal ulcers cause a sharp and intense pain that runs through the top of the navel to the chest’s center. If the pain [6] is prolonged and without any form of relief, it may cause the person to feel nauseous or vomit.
It alters the normal state of your digestive tract and may cause feelings of nausea after prolonged cramps, when hungry, or immediately after eating.
