Enteritis and gastroenteritis are different diseases, but they are interrelated. Enteritis and gastroenteritis occur in different places. Enteritis refers to inflammation of intestinal mucosa, including acute enteritis and chronic enteritis. The main symptom is diarrhea. Acute enteritis is often accompanied by fever, chills, nausea, vomiting, etc., while chronic enteritis is mainly characterized by abdominal pain, abdominal distention, bloody stool, mucus stool, pus and blood stool. The lesion of gastroenteritis is located in the gastrointestinal tract. In addition to the symptoms of the intestinal tract, there is also stomach discomfort, which is manifested by abdominal distention, pain, acid regurgitation, belching, and loss of appetite. Repeated attacks of gastroenteritis can also lead to body wasting and malnutrition. The causes of the two diseases are different. Enteritis can be caused by various reasons, while gastroenteritis is mostly caused by microbial infection, such as overeating, eating raw and cold, eating unclean, and using infected tableware.
