Vomiting is super hard to bear. It may be due to gastric ulcer, acute gastroenteritis, intestinal obstruction, etc. It can be relieved by general treatment, medication and surgery. 1. Gastric ulcer: metoclopramide can be given to stop vomiting. If Helicobacter pylori is present, amoxicillin, clarithromycin, omeprazole, colloidal bismuth pectin and other medications can be given. 2. Acute gastroenteritis: first of all, fasting and water prohibition, gastrointestinal rest for 4~6 hours after vomiting relief, you can drink a small amount of warm boiled water to promote intestinal peristalsis to restore the rhythm. If the bacterial infection, accompanied by diarrhea, can be given amoxicillin, bifidobacteria and other medications, vomiting and diarrhea may lead to severe acid-base electrolyte disorders, pay attention to rehydration to correct metabolic acidosis, replenish potassium chloride and other electrolytes to correct electrolyte disorders. 3. Intestinal obstruction: the obstruction can be unblocked through adhesion release surgery, intestinal resection and intestinal anastomosis, etc. to improve the vomiting. It is recommended to consult a doctor in time and use medication under the guidance of a physician, not self-medication.
