Patients with irritable bowel syndrome may experience stomach discomfort, as irritable bowel syndrome may be a type of functional dyspepsia. Therefore, patients with functional dyspepsia may experience stomach discomfort, which manifests as bloating, early satiety, belching, acid reflux, heartburn, etc. Once patients experience stomach discomfort, it is recommended to visit the gastroenterology department of a reputable hospital as soon as possible to complete a gastroscopic examination and a carbon-13 breath test, as well as to check for Helicobacter pylori. When necessary, targeted symptomatic treatment should be conducted.
