My stomach aches, how is to return a responsibility, these days did not eat what cold thing ah

Stomach pain may be induced by improper diet, abdominal cold and overeating, or may be induced by gastritis, gastric ulcer and duodenal ulcer. Gastrointestinal examination should be performed in hospital. If gastric ulcer is diagnosed, acid suppressants and gastric mucosal protective agents should be taken as prescribed.
