Doctor's answer:

The main symptoms of gastroenteritis include, in addition to the usual nasal congestion, runny nose, and cough that we are familiar with, the primary manifestation of symptoms such as nausea, vomiting, and diarrhea, which are also typical of gastroenteritis. It presents with both symptoms of gastroenteritis and fever. However, in your description, there are no signs of fever at all, so it is not entirely ruled out as pediatric gastroenteritis. If there are indeed fever symptoms present, it can be confirmed as gastroenteritis with fever.
1. In the next two days, give the child more fluids and eat easily digestible foods, such as porridge or rice soup.
2. Take oral medications to regulate the balance of the gastrointestinal environment, such as probiotics like Mimi Ai, while also suggesting the use of anti-inflammatory drugs like cephalexin granules, which are effective for both the respiratory tract and the gastrointestinal tract.
3. If there is a significant increase in urine output, it indicates dehydration. It is recommended to administer intravenous fluids.
