Acute gastroenteritis is generally considered an infectious disease, not merely a stomach ailment. Clinically, acute gastroenteritis is commonly thought to be caused by viruses or bacteria, especially due to insufficient hygiene. The typical clinical manifestations include abdominal pain, bloating, nausea, vomiting, diarrhea, etc. Of course, some patients may also experience fever. Diarrhea and vomiting are the most common symptoms observed clinically, with vomiting generally involving stomach contents without blood. Diarrhea is characterized by an increased frequency of bowel movements, with stools being loose and watery, particularly frequent at night, making the symptoms of diarrhea especially prominent in patients seeking medical attention. Treatment for patients generally focuses on symptomatic relief, although in cases of recurrent fever, the cautious use of antibiotics may be considered.
