Vomiting in children
Overview
Vomiting in children affects the digestive or urinary system in children. The pattern can be brief and self-limiting or require targeted investigation and ongoing care.
Children vary in development, symptoms and response to treatment. This guide cannot diagnose a child and should support, not replace, individual professional care.
Signs and symptoms
Possible features include abdominal discomfort, changes in stool or urine, nausea, vomiting, reduced appetite, tiredness or altered growth.
Look at the whole child, including comfort, alertness, breathing, drinking, urine output, sleep, growth, learning and participation in usual activities.
Causes
Causes range from infection and diet-related effects to inflammation, anatomical differences, inherited conditions or functional gut-brain interactions.
Risk factors
Age, family history, recent infection, medicines, hydration, diet and another health condition may influence likelihood. Risk factors are not diagnostic, and some affected children have none.
Diagnosis
A clinician reviews timing, bowel and urinary patterns, diet, growth and examination. Urine, blood, stool tests or imaging may be selected.
Treatment options
Treatment targets the cause and may include oral rehydration, dietary support, medicine, specialist monitoring or a procedure.
Plans should be age appropriate, family centred and reviewed as the child grows. Medicines must be used only at the recommended dose and with professional guidance.
Home management
Keep a record of pain, stool or urine, fluids and foods. Support regular drinks and meals unless the clinical team advises a specific plan.
Prevention
Hand hygiene, safe food handling, adequate fluids, fibre appropriate for age and timely toilet access can prevent some problems, but not all.
Long-term outlook
Many short-term problems resolve fully. Chronic conditions can often be controlled with coordinated medical, dietetic and family support.
Possible complications
Dehydration, nutritional deficiency, bleeding, infection, obstruction or effects on growth may occur depending on the cause.
When to seek urgent medical care
Urgent assessment is needed for severe or localised worsening pain, green vomit, blood, a swollen abdomen, dehydration, reduced responsiveness or inability to pass urine.
Call emergency services for severe breathing difficulty, blue or grey colour, collapse, a seizure lasting longer than local emergency guidance, reduced responsiveness or rapidly worsening illness.
Frequently asked questions
Does my child need tests?
Not always. Testing depends on age, history, examination and whether a result will change treatment.
Can my child attend school?
Many children can participate with suitable adjustments. Keep a child home when acutely unwell and follow the care plan and local attendance guidance.
When should we arrange follow-up?
Use the schedule given by the healthcare team and request earlier review for worsening symptoms, new concerns, treatment side effects or changes in growth, learning or daily function.
Summary
Accurate assessment separates common temporary symptoms from conditions requiring prompt or ongoing treatment.
