What causes sudden stomach pain in children?

Sudden abdominal pain in children may be caused by cold exposure, food poisoning, ascariasis, or acute appendicitis. 1. Abdominal cooling due to not covering with a blanket during sleep, excessive consumption of cold beverages, or exposure to air conditioning may lead to gastrointestinal dysfunction and cause abdominal pain. Use pepsin tablets, aluminum magnesium carbonate suspension, and bifidobacterium triple viable capsules under a doctor's guidance. 2. Consumption of unhygienic or raw/cold food may cause intestinal infection, resulting in symptoms such as abdominal pain and diarrhea. Use sodium bicarbonate injection, propantheline bromide, atropine, and anisodamine under a doctor's guidance. 3. Ascariasis is transmitted via the fecal-oral route; once infected, symptoms such as nausea, vomiting, and abdominal pain may occur. Use levamisole, mebendazole, or albendazole under a doctor's guidance. 4. Acute appendicitis: pain is located in the lower right abdomen and may be accompanied by fever; seek timely medical attention. If a child suddenly experiences abdominal pain, it is recommended to visit a reputable hospital promptly to avoid delaying treatment.
