Vomiting and regurgitation are very common presenting symptoms to the doctor and can cause great concern to both parents and doctors.
- Although some 50% of infants have regurgitation or vomiting as an isolated complaint, less than 5% have significant underlying disease.
- Investigations should be tailored to confirm the suspected diagnosis, exclude complications of vomiting and make an assessment to assist management.
- Healthy thriving infants with regurgitation or mild uncomplicated gastro-oesophageal reflux do not require any investigation.
- Warning signs requiring investigation or referral include: bilious vomiting; persistent, severe or recurrent vomiting; and vomiting associated with abdominal pain, lethargy, failure to thrive or neurological signs.
