What could be the reason for a 7-year-old child frequently experiencing stomach pain?

Abdominal pain in 7-year-old children is often due to poor diet, constipation, or other causes, and may also be related to ascariasis (roundworm infection). 1. Consuming excessive amounts of hard-to-digest, raw, cold, or chilled foods may increase the burden on the gastrointestinal tract and irritate the gastrointestinal mucosa, leading to symptoms such as bloating and dull abdominal pain. It is recommended to correct unhealthy eating habits, maintain a balanced diet, and engage in appropriate physical activity based on individual conditions. 2. If intestinal peristalsis is too slow, ingested food may accumulate in the gastrointestinal tract and remain undigested. Over time, this can lead to abnormally dry and hard stools with difficulty in defecation, accompanied by symptoms such as abdominal masses and tenderness upon pressure. Treatment under medical guidance may include medications such as enemas (e.g., glycerin suppositories) or Compound Aloe Capsules. 3. Ascariasis: This typically refers to infection of the intestinal mucosa by roundworms, possibly caused by poor dietary hygiene. It is recommended to follow medical advice for treatment with medications such as mebendazole tablets or albendazole tablets. It is advisable to seek timely medical evaluation and treatment.
