Gastric flatulence

When inflammation, reflux, or tumors exist in the stomach and duodenum, gastric emptying is delayed, and food continuously exerts pressure on the gastric wall; simultaneously, excessive fermentation of food in the stomach produces a large amount of gas, further increasing intragastric pressure, thus resulting in upper abdominal fullness and a feeling of pressure, i.e., gastric bloating. Gastric bloating refers to a condition characterized by a persistent feeling of distension in the epigastric region, with visible abdominal distension. It may be accompanied by epigastric pain, nausea, vomiting, loss of appetite, and mental depression. After food is digested, absorbed, and transported through the digestive system, nutrients can be delivered to all parts of the body. The digestive system gradually ages with increasing age, and difficult-to-digest foods place a burden on the gastrointestinal tract, also affecting one's health.
