At a glance
- Constipation, infections and problems outside the bowel can cause a tummy ache.
- Severe or worsening pain, green vomit, blood or pain with testicular swelling need urgent care.
- Pain near the belly button does not by itself tell you the cause.
When should we get urgent help?
Go to an emergency department for severe constant pain, inability to walk normally because of pain, green vomit, blood in vomit or stool, or a very swollen painful belly. Sudden testicular pain or swelling can present as a stomachache and needs emergency assessment. Call 911 if your child collapses, is too weak to stand or cannot be woken normally.
Contact a clinician promptly for pain becoming constant or worse, pain low on the right side, repeated vomiting, markedly less urine, fever with an unwell child, or pain after an injury. A baby or toddler with persistent unexplained pain or repeated bouts of intense crying should be assessed rather than treated as having an ordinary stomachache.
What commonly causes a child's stomachache?
Hard, difficult stools can point toward constipation. Vomiting and diarrhea may accompany a gut infection. Pain when peeing or new urinary accidents can suggest a urinary infection. A sore throat with fever can sometimes come with belly pain too.
Recurring pain can involve the connection between the gut and brain. The pain is real, even when stress plays a part. Arrange an examination before assuming repeated pain is anxiety or changing your child's diet extensively.
Could pain around the belly button be appendicitis?
Appendicitis can begin near the belly button and move toward the lower right abdomen. Pain may worsen over hours or with movement, and appetite may drop. Children do not always have the classic pattern, and diarrhea does not rule it out. Seek urgent assessment if you suspect appendicitis; do not wait for every symptom to appear.
What can I do for mild pain at home?
If pain is mild and your child is otherwise well, let them rest, offer fluids and allow an unhurried toilet visit. Offer food according to appetite. Keep checking how they feel; home observation is appropriate only while symptoms remain mild and improve.
Record when pain started, its location, bowel movements, vomiting, temperature and urine changes. Contact the pediatrician if mild pain persists into the next day, repeatedly interrupts school or sleep, or comes with weight loss or poor growth. Do not start laxatives for new unexplained pain without advice.
Common questions
Does pain after eating mean a food allergy?
Not necessarily. Constipation and other digestive problems can also cause pain after meals. Track the pattern and discuss it with the pediatrician before removing major foods.
Can a child have appendicitis without a fever?
Yes. No single symptom, including fever, is required. Worsening pain and your child's overall condition matter.
