Acute gastroenteritis refers to acute inflammation of the gastrointestinal tract, characterized by abdominal pain, nausea, and vomiting. This condition does not involve constipation. In cases of mild diarrhea caused by acute gastroenteritis, the general condition is good, with fewer than ten bowel movements, and the stool sometimes appears like egg drop soup. For more severe diarrhea, there might be more than ten bowel movements per day, and treatment should primarily focus on antidiarrheal, pain relief, and antiemetic medications. It is also important to rest adequately, hydrate promptly, and follow a diet of eating small, frequent meals. If the condition is severe, treatment might involve gastrointestinal decompression and parenteral nutrition.
