Patients with gastritis usually do not have pain in the navel or around the navel. The main location of pain in gastritis is under the glabella, or in the left upper abdomen or epigastrium. The clinical manifestations of gastritis are usually paroxysmal distension, with regular episodes, closely related to diet, and mostly without radiating pain. The pain is limited in location and can be relieved by acid suppressant therapy. In the case of peptic ulcer patients, such as gastric ulcer, the typical manifestation is pain after eating, while the typical clinical manifestation of duodenal ulcer is pain when hungry, which can be relieved after eating. For patients with belly button pain, it is mostly considered to be intestinal spasm, or other abdominal organ problems. It is recommended that if the pain is more persistent in the navel area, or accompanied by other discomfort, it is recommended that the patient should go to the hospital in time to cooperate with the doctor to give examination and treatment.
