The sudden appearance of regurgitation and vomiting is usually considered as the possibility of acute gastritis, in addition to acute pancreatitis and intestinal obstruction, cholecystitis, etc. can not be excluded. If there is no abdominal pain, oral domperidone tablets can be given to improve the vomiting symptoms. If the abdominal pain is accompanied by vomiting after eating food, the possibility of pancreatitis is more likely. It is recommended to fast from food and water, and to visit the hospital for abdominal ultrasound and blood and urine amylase measurement. If there is a recent anal cessation of exhaustion and defecation at the same time, the main consideration is the possibility of intestinal obstruction, mainly due to the symptoms caused by intestinal discomfort, in this case, it is recommended to take a standing abdominal plain film to check whether there is a liquid and gas plane, and if necessary, for enema or gastrointestinal decompression for further treatment. Regardless of the causes of regurgitation and vomiting, we should pay more attention to avoid electrolyte disorders caused by frequent vomiting.
