Gastroscopy should be done for frequent bloating because frequent bloating indicates indigestion. Dyspepsia can be either functional dyspepsia or organic dyspepsia. The cause of indigestion can be clarified through gastroscopy, and if it is organic indigestion, such as atrophic gastritis, gastric erosion, gastric polyps, it needs to be treated, which can block the development towards gastric cancer. If there is no organic lesion, and it is considered to be functional dyspepsia, it can be treated symptomatically, and the symptoms can be improved through diet, such as eating small meals, avoiding greasy food, eating more vegetables and fruits, keeping a happy mood, and exercising regularly.
