Nausea and vomiting after cholecystectomy is a normal postoperative reaction, but if it is combined with other symptoms such as fever, abdominal pain and jaundice, it is not a normal phenomenon and needs to be treated in time. After gallbladder removal, bile concentration will be affected to some extent, and bile excretion will be irregular, so after eating fatty food, there is a possibility of dyspepsia, such as nausea, steatorrhea, abdominal distension, etc., which is a normal postoperative reaction. This is a normal postoperative reaction. It can be improved by adjusting the dietary structure, such as quitting alcohol and avoiding high-fat food, and overeating should be avoided. However, if nausea is more severe after cholecystectomy and is combined with fever, abdominal pain, vomiting or jaundice, it may be post-cholecystectomy syndrome or adhesive bowel obstruction, which are not normal phenomena and require prompt medical treatment.
