Bloating and stomach distress are related to factors such as indigestion, improper diet, and digestive tract obstruction. The appearance of indigestion is related to factors such as insufficient secretion of digestive juices and insufficient gastrointestinal power. Since the food in the stomach cannot be discharged into the intestine in time, it will ferment badly and produce gas, resulting in stomach distension. Some people’s food in the stomach may even appear to rot, and cause irritation to the stomach wall, inducing stomach discomfort. If a large amount of spicy and gas-producing food is consumed in the daily diet, not only will the food irritate the mucous membrane of the stomach wall and cause pain in the stomach, but also a large amount of gas will be produced during digestion, leading to symptoms of distension in the abdomen. Gastrointestinal obstruction mainly includes pyloric obstruction and intestinal obstruction. When pyloric obstruction occurs, food in the stomach cannot enter the intestine through the pylorus, causing stomach discomfort. When intestinal obstruction occurs, the contents of the intestine cannot pass smoothly, resulting in excessive expansion of the intestinal wall, which will not only cause abdominal distension, but also stomach discomfort.
