growth with nausea

Overview

This refers to a child who both feels sick (nausea) and is not growing as expected. It is not a disease itself, but a sign of an underlying health problem that needs checking.

Nausea is common in children, but nausea together with poor growth is less common and always needs medical attention.

It can affect babies, toddlers, and older children. Some conditions start in early infancy.

Symptoms

Common symptoms

• Feeling sick often
• Vomiting
• Poor appetite
• Weight loss or no weight gain
• Tummy pain

Symptoms in children

• Irritability during feeding
• Arching back after feeding
• Recurrent vomiting
• Low energy

Causes

Main causes

• Gastroesophageal reflux (stomach acid coming up into the food pipe)
• Food allergy or intolerance
• Slow stomach emptying
• Infection (such as a stomach bug)
• Metabolic disorder (a problem with how the body processes food)
• Urinary tract infection
• Structural problem in the digestive tract, such as pyloric stenosis

Risk factors

• Born prematurely
• Family history of reflux or food allergies
• Certain long-term medical conditions

When to see a doctor

See a doctor urgently if:

• Severe tummy pain
• Frequent or forceful vomiting
• Blood in vomit or poo
• Signs of dehydration (dry mouth, fewer wet nappies, sunken eyes)
• Weight loss

Book a routine appointment if:

• Nausea lasting more than a few days
• Not gaining weight well
• Poor feeding in a baby
• Frequent vomiting that is not severe

Diagnosis

The doctor will ask about symptoms, feeding habits, and family history, and will check your child's growth on a chart. They may examine the tummy and look for signs of illness.

Tests that may be done

• Height, weight, and head circumference measurements (for babies) to track growth
• Urine test
• Blood tests
• Stool tests
• Ultrasound or other imaging of the tummy
• Tests for allergies

What to expect at your appointment

You will be asked about vomiting and poo patterns, appetite, and any other symptoms. Your child may need more than one visit to see how growth changes over time.

Treatment

Treatment depends entirely on the cause. Once the underlying condition is found, the doctor can suggest the best way to help your child feel better and grow.

Self-care at home

• Offer small, frequent meals
• Keep your child upright after eating
• Avoid foods that seem to trigger the nausea
• Make sure your child drinks enough fluids in small sips
• Keep a diary of vomiting and weight changes

Medical treatments

Doctors may recommend prescribed medicines to reduce stomach acid or treat an infection. Referral to a dietitian or a children's specialist may be needed for allergies or metabolic problems.

When is surgery considered?

In rare cases, a structural problem such as pyloric stenosis needs a surgical procedure to fix it.

Living with this condition

Living with a child who has nausea and growth concerns involves regular weighing, close monitoring of eating, and lots of patience. Your healthcare team can guide you.

Lifestyle tips

• Keep feeding routines calm and relaxed
• Avoid messy or stressful meal times
• Track symptoms to spot patterns

Diet and exercise

A balanced diet appropriate for your child's age is important, but specific changes depend on the cause. Exercise, tummy time, and fresh air can help overall well-being.

Mental health and emotional wellbeing

Nausea and feeding problems can be stressful for both you and your child. It is normal to feel worried or frustrated. Talk to your doctor about support if you are struggling. If you are feeling very distressed, please contact your local mental health crisis service or call your local emergency number.

Prevention

Many causes cannot be prevented because they are part of how a child develops. Avoiding secondhand smoke and following a healthy feeding plan can support growth. Treating causes like reflux early may prevent complications.

Vaccines

Keeping your child's routine vaccinations up to date can prevent some infections that cause vomiting and poor feeding.

Screening programmes

Growth checks and regular weigh-ins are a form of screening carried out by health visitors and GPs. There is no specific screening test for this symptom combination.

Complications

If left untreated

• Dehydration
• Low weight and lack of vitamins and minerals
• Delays in development

Long-term outlook

With the right diagnosis and care, most children begin to gain weight and feel better. The outlook depends on the cause, but health professionals are very experienced in helping children with these symptoms.
