When should you see a doctor for Abdominal pain - children under age 12?
Last updated September 7, 2026.
Most stomach aches in young children settle within a few hours, but you should call a doctor the same day if the pain is severe, keeps getting worse, or comes with fever, repeated vomiting, or signs of dehydration. What changes the answer is how the pain behaves over time and what comes with it. Pain that stays in one spot, especially the lower right side, or that makes your child curl up, limp, or refuse to walk needs prompt evaluation. Pain that comes and goes, eases after a bowel movement or passing gas, and lets your child play and eat is usually less concerning. Keeping a simple log of when the pain starts, what your child ate, bowel movements, and temperature makes the visit far more useful. Offer small sips of fluid often, and skip pain medicine until a clinician has checked a belly that is tender to touch.
What to do
- Watch the clock: Pain that steadily worsens over several hours or keeps your child from sleeping deserves a same-day call.
- Track fluids: Count wet diapers or trips to the bathroom, and get care if your child has not urinated in about 8 hours.
- Note the location: Pain that starts near the navel and moves to the lower right side, with fever and vomiting, needs urgent evaluation.
- Hold the pain relievers: Do not give ibuprofen or laxatives for an undiagnosed tender belly, and never give aspirin to a child.
- Rehydrate slowly: Offer small, frequent sips of an oral rehydration solution rather than large drinks or sugary soda.
- Log the pattern: Write down timing, meals, stools, and temperature so recurring pain can be sorted out at the visit.
