Acute enteritis and acute gastroenteritis are both common diseases in the gastroenterology department, and the difference between the two can be analyzed in terms of etiology and clinical manifestations: 1. etiology: acute enteritis is mainly caused by intestinal infection or unclean diet, chemical and drug poisoning, food allergies, etc.; acute gastroenteritis is an acute inflammation caused by various etiologies that simultaneously stimulate the gastrointestinal mucosa, and can generally be divided into infectious and non-infectious acute The abdominal pain that occurs in acute enteritis is mostly located in the periumbilical region, with varying degrees of pressure pain, generally paroxysmal dull pain or colic, mainly abdominal pain, diarrhea, accompanied by varying degrees of nausea, headache, bloating, weakness of the limbs, and severe diarrhea may lead to dehydration. In contrast, the pain of acute gastroenteritis first appears mostly in the upper abdomen, and as the disease progresses there may be irregular abdominal pain. Its clinical symptoms are mainly nausea and vomiting, accompanied by diarrhea, abdominal pain, weakness of the limbs and fever. The principles of treatment for both acute enteritis and acute gastroenteritis are to eliminate the causes, treat the symptoms, and correct the imbalance of water and electrolyte acid-base balance caused by diarrhea. Pay attention to dietary hygiene, wash hands regularly, and avoid eating uncooked food.
