The common causes of right upper abdominal distension are acute and chronic gastritis and indigestion. During the onset of chronic gastritis, the patient’s gastric motility will be abnormal, and the food intake will not be digested and decomposed well, and the patient will show right abdominal flatulence because the food will stop in the stomach for a long time and cannot be discharged by the digestive system. When indigestion occurs, the peristaltic function of the patient’s intestines and stomach will slow down, resulting in the prolonged retention of food in the digestive system. The right upper abdomen can be improved by using massage after the phenomenon of flatulence, and can also be treated with drugs that promote digestion, such as domperidone tablets and mosapride tablets.
