The thickening of the stomach wall may lead to epigastric pain, acid regurgitation, belching, nausea, vomiting, and burning sensation behind the sternum. Such pain can be manifested as dull pain, distention pain, or burning pain. Severe patients may also have hematemesis and tarry stool symptoms. The reason for the thickening of the gastric wall may be the inflammation and tumor of the stomach. Electronic gastroscopy and pathological biopsy are required to make a clear diagnosis of the disease.
