Bloating and gas after meals may be caused by physiologic factors such as excessive food intake at one time, and pathologic factors such as gastric ulcers and indigestion. 1. Physiological factors: If the patient consumes too much food at one time and a large amount of indigestible food, such as fried oil, nuts, etc., then the food will accumulate in the stomach because it is not easy to be digested. At this time, the food is not easy to digest and accumulates in the stomach, resulting in bloating and gas after meals. 2. Pathological factors: (1) Gastric ulcer: If the patient suffers from gastric ulcer disease and does not pay attention to diet in daily life, it will cause abnormal gastrointestinal function. It leads to the situation of bloating and holding breath after meals. (2) Indigestion: due to long-term diet irregularities, such as overeating, increasing the burden on the stomach and intestines. As the previous meal has not been digested completely, there is a large amount of food intake at this time. This leads to a large accumulation of food in the stomach, at which time indigestion occurs. At this time there may be bloating and holding breath after meals. It is recommended that when this symptom occurs, the cause of the disease should be identified in a timely manner, and the use of medication under the advice of a physician. At the same time, pay attention to diet regulation, avoid intake of stimulating spicy food, avoid overeating.
