Belching after eating may be related to the food consumed. Eating more flatulent foods such as potatoes, sweet potatoes, yams, soy products or eating quickly can lead to belching after eating, and drinking drinks with gas can also lead to belching. In addition to food factors, it is related to the patient’s gastrointestinal motility and digestive function, and belching and burping after eating can also occur if the gastrointestinal motility is poor. Digestive dysfunction such as lack of digestive enzymes may also cause belching, and it is recommended to add gastrointestinal peristaltic drugs such as Mosapride and digestive enzyme preparations to treat the symptoms. If belching occurs frequently after eating, it is recommended that patients undergo H. pylori testing, gastroscopy, and ultrasound to rule out H. pylori infection, peptic ulcers, acute and chronic gastritis, and biliary and pancreatic diseases.
