How is Abdominal pain - children under age 12 treated?
Last updated September 7, 2026.
**Most abdominal pain in children under 12 is treated at home with fluids, rest, simple food, and attention to constipation, since the common causes are constipation, viral stomach bugs, gas, and mild reflux.** Treatment changes with the cause and the pattern of pain. Pain that comes and goes around the belly button, improves after a bowel movement, and does not wake your child at night usually points to something mild. Pain that stays in one place, especially low on the right side, or that comes with repeated vomiting, fever, or blood in stool, needs a clinician the same day. Daily habits that help include regular water, fruit and vegetables, unhurried toilet time after meals, and slower eating with fewer sweetened drinks. Keep a short log of when the pain happens and what your child ate and passed, because that record often reveals the cause faster than any test.
What to do
- Treat constipation first: If stools are hard, infrequent, or painful, add water and fiber and ask your clinician about a child stool softener before assuming another cause.
- Rehydrate in small amounts: With vomiting or diarrhea, give a teaspoon or two of oral rehydration solution every few minutes rather than a full glass at once.
- Dose by weight: Use the dosing device that comes with the acetaminophen or ibuprofen bottle and dose by your child's current weight, not their age.
- Skip aspirin and anti-diarrheals: Aspirin is not for children, and loperamide-type medicines can be harmful in young children unless a clinician directs their use.
- Feed normally when able: Return to a regular diet as soon as your child is keeping fluids down; long liquid-only diets slow recovery.
- Get same-day care for red flags: Pain fixed low on the right side, green vomit, blood in stool, a rigid belly, or signs of dehydration need an in-person exam.
