Symptoms in older adults

Causes
Main causes
- Strong exercise can squeeze the organs and muscles in the belly
- Eating a large meal or drinking fizzy drinks shortly before exercise
- Breathing too shallow or irregularly during activity
- Tight or tired stomach muscles
Risk factors
- Skipping a warm-up
- Not drinking enough water
- Playing high-intensity sports without breaks
- A tendency to get constipated or have gas
When to see a doctor
See a doctor urgently if:
- Call your local emergency number if your child has any of the emergency symptoms listed above.
Book a routine appointment if:
- Book a non-urgent appointment if the pain is frequent, severe, or interfering with sports
- Also see the doctor if your child has poor weight gain, ongoing tummy troubles, or pain in other parts of the body
Diagnosis
A doctor will ask about the child’s symptoms, when the pain happens, and any other health issues. They will gently feel the belly.
Tests that may be done
- Physical examination
- Review of eating and exercise habits
- Urine test, if a urinary infection is possible
- Ultrasound or other imaging, only if pain is severe or unusual
What to expect at your appointment
For typical exercise-related colic, no tests are needed. The doctor may ask you to keep a diary of symptoms and activities and to try simple measures at home.
Treatment
The main goal is to relieve symptoms. Most children feel better with rest, gentle breathing, and changes to how they prepare for exercise.
Self-care at home
- Stop the activity and rest until the pain goes
- Breathe slowly and deeply
- Place a warm cloth or hot water bottle (wrapped) on the belly
- Give small sips of plain water
- Gradually stretch the side that hurts
Medical treatments
If the pain is linked to another problem like acid reflux or constipation, the doctor may suggest changes to diet, meal timing, or other non-drug approaches. Any medicine should only be given under the advice of a qualified healthcare provider.
When is surgery considered?
Surgery is not needed for exercise-related colic.
Living with this condition
Help your child tune into their body. A little discomfort is normal, but they should not push through sharp pain.
Lifestyle tips
- Warm up with light exercise before sports
- Avoid heavy meals for one to two hours before activity
- Encourage regular bathroom routines to avoid constipation
- Build up fitness gradually so the body adapts
Diet and exercise
Regular exercise and a balanced diet support strong, flexible muscles. Before activity, choose light snacks like a banana or plain crackers, and drink water rather than sugary drinks.
Mental health and emotional wellbeing
Repeated pain can make a child anxious about sports. Reassure them that this is common and that they can learn to manage it. Encourage small steps back into activity.
Prevention
Often yes. Simple habits such as warming up, pacing activity, and avoiding big meals beforehand can reduce the chance of colic after exercise.
Vaccines
There is no vaccine for exercise-related colic.
Screening programmes
No specific screening test is needed for healthy children, but regular well-child checkups help spot any underlying issues.
Complications
If left untreated
- Exercise-related colic itself is not dangerous
- But ignoring severe or repeated pain could delay finding a more serious problem, like appendicitis, bowel issues, or a urinary infection
Long-term outlook
For almost all children, colic after exercise is temporary and improves with rest and simple adjustments. They can continue to enjoy playing and sports once the pain has gone.
