What causes children to vomit when they have stomachache

Children with stomach pain and vomiting may be caused by allergic reactions, acute gastroenteritis, gastrointestinal colds and other reasons.

If the child's constitution is sensitive and often eats foods rich in foreign protein, it is easy to induce allergic reactions, causing abdominal pain, vomiting, diarrhea and other symptoms.

2. Acute gastroenteritis

Acute gastroenteritis can lead to severe decline in gastrointestinal function, children will stimulate the gastrointestinal tract after eating, but also cause symptoms of stomach pain and vomiting.

3. Gastrointestinal colds

Gastrointestinal colds are gastrointestinal disorders caused by viral infection. Children can stimulate abnormal gastrointestinal motility after eating, which can also cause the above symptoms.
