Digestive tract symptoms are generally poorly treated. Repeated upper abdominal pain, abdominal distension, acid reflux, heartburn and other symptoms occur. When the general treatment effect is not good, these discomfort symptoms of the upper digestive tract may indicate the existence of gastritis, peptic ulcer and other diseases.
