Belching is the sudden flow of gas, small amounts of digestive juices, and food from the stomach back into the esophagus and mouth. It may be caused by pyloric obstruction, indigestion and insufficient gastric power. 1. Pyloric Obstruction: Due to incomplete obstruction of the pylorus, stomach contents and small amount of gas cannot be discharged to the small intestine, therefore, it will easily flow back to the esophagus and mouth, resulting in picking up of breath. Ginseng Spleen Enhancing Pills can be taken for treatment and relief. 2. Indigestion: Poor digestion and decreased functioning of the digestive system will lead to reflux of food back to the esophagus and mouth, resulting in picking up of chi, which can be relieved by taking Gastric Strengthening Tablets or Lactobacillus Granules for treatment. 3. Insufficient Gastric Motility: Insufficient peristalsis due to contraction of stomach muscles will cause symptoms such as loss of appetite, nausea and vomiting, accompanied by symptoms such as food reflux. It can be treated with drugs such as domperidone tablets. When patients have the above symptoms, it is recommended that they go to the hospital for examination and diagnosis in time, and take medication under the guidance of the doctor.
