Gastric flatulence may be caused by physiological factors such as overeating and pathological factors such as gastritis and gastric ulcer. Gastric flatulence can be treated by intestinal microecological agents such as Bacillus subtilis bifidus, proton pump inhibitors such as omeprazole and gastric stimulants such as cisapride. 1. Physiological factors: probiotics such as Lactobacillus, Bifidobacterium lactis triplex, Bacillus subtilis bifidus and other probiotics can effectively alleviate the symptoms of bloating, abdominal pain, nausea, loss of appetite, diarrhea, constipation, etc., promote gastrointestinal motility, and improve the digestion and absorption of food in the gastrointestinal tract. 2. Pathological factors: proton pump inhibitors: such as omeprazole, lansoprazole, epprazole, etc., can effectively inhibit the secretion of gastric acid, thereby relieving the symptoms of acid reflux, heartburn, nausea, bloating, stomach pain caused by excessive secretion of gastric acid, etc.; intestinal micro-ecological agents: such as Lactobacillus, Bifidobacterium lactis trilobium, Bacillus cereus bacillus bifidus, and other probiotic bacteria, which can effectively alleviate abdominal bloating, abdominal pain, nausea, loss of appetite, diarrhea, constipation and other symptoms, promote gastrointestinal motility and improve digestion and absorption of food in the gastrointestinal tract. Patients with flatulence are advised to consult a doctor in time for a clear diagnosis and targeted treatment. In addition, all of the above medications should be taken under the guidance of a doctor and should not be used without authorization.
