Flatulence right after eating is related to indigestion, gastrointestinal dysfunction, improper diet and other factors. First of all, people with physical indigestion have relatively little secretion of digestive juices, and the difficulty of digesting food after ingesting food will relatively increase, thus causing pressure on the stomach wall and thus producing a feeling of bloating. Secondly, once the gastrointestinal dysfunction occurs, the food cannot be discharged into the duodenum in time, so it will ferment badly in the stomach and produce a lot of gas, resulting in increased pressure in the stomach, which will also cause gastric distension. Finally some people in the diet will prefer to eat beans, onions, sweet potatoes and other foods, this type of food, although nutritious, but is easy to produce gas food, in the process of digestion will produce a lot of gas, so the stomach will exist with the feeling of flatulence. People who are bloated after eating can properly massage their abdomen or use drugs such as domperidone and mosapride for relief.
