The vague pain under the right rib cage after eating is related to chronic gastritis, gastric ulcer, dyspepsia, gastroptosis and other factors. In people with chronic gastritis, because of congestion and edema on the gastric mucosa, food will cause friction on the gastric mucosa after eating, so it will induce vague pain in the stomach, and because the stomach body is mainly located under the right rib cage of the human body, the performance of vague pain under the right rib cage will appear. In some people, ulcer surface will exist on the stomach body, and food will stimulate gastric acid secretion after food intake to help digestion of food, and once the digestive juices come into contact with the ulcer surface, it will lead to pain in the area of the ulcer surface. Some people who suffer from indigestion themselves will aggravate the symptoms of indigestion after excessive satiety. People with indigestion will experience stomach pain when their gastrointestinal burden increases after excessive satiety, which affects the digestive function of the stomach. Some people suffer from gastric prolapse themselves, and these people should try to avoid excessive satiety, otherwise it will cause the symptoms of gastric prolapse to worsen, and at the same time affect the digestive function of the stomach for food, so the hidden pain under the right rib cage will appear after eating full.
