There are many reasons for stomach bloating, regurgitation and vomiting, the common ones are acute gastroenteritis, peptic ulcer and gastroesophageal reflux disease, which need to be treated after clarifying the cause of the disease, including general treatments such as supplemental fluids and rest, medications such as Domperidone, Clarithromycin, Omeprazole, etc. and surgical treatments. 1. Acute gastroenteritis: light diet, supplemental water, adequate rest. Antibiotics such as norfloxacin and amoxicillin can be used to fight bacterial infection. For quick relief of symptoms, domperidone (gastric stimulant), metoclopramide or ondansetron (antiemetic) can be used. 2. Peptic ulcer: treatment with oral medication. (1) Quadruple therapy, such as omeprazole, bismuth potassium citrate, clarithromycin, metronidazole, etc., is needed if Mycobacterium pylori infection is present. (2) Acid inhibitors: proton pump inhibitors, such as omeprazole, pantoprazole. (3) Gastric mucosal protectant: e.g. aluminum thioglycollate. (4) Surgery is needed if symptoms are severe and oral medications are ineffective. 3. Gastroesophageal Reflux Disease (GERD): For those with mild symptoms, oral proton pump inhibitors and gastric stimulants can be taken, together with weight reduction, alcohol cessation, avoiding food and drink before bedtime and elevating the head during sleep, etc. If the symptoms don’t get better or worsen with the oral medication, surgical treatment is needed. It is recommended to go to the hospital, under the guidance of the doctor for treatment.
