If the stomach is uncomfortable, further relevant tests, such as electronic gastroscopy, are needed to rule out peptic tumors and peptic ulcers. If no clear peptic tumor, and peptic ulcer is seen in the e-gastroscopy, further monitoring of H. pylori needs to be improved. This is because H. pylori infection may also cause symptoms such as upper abdominal fullness, vague pain, nausea, acid reflux and belching. If H. pylori monitoring is negative, functional dyspepsia may be present, and digestive support medications such as Gastrointestinal Oral Liquid and gastrointestinal motility drug Mosapride should be taken.
