Shortness of breath in children

Overview

Shortness of breath is when a child feels like they can't get enough air or are breathing harder than usual. It is also called breathlessness or difficulty breathing. In children, it can happen suddenly or develop over time and is often a sign that the body is working hard to get oxygen.

Yes, shortness of breath is very common in children, especially in the first few years of life. Most children will experience it at some point due to a mild illness.

Shortness of breath can affect children of all ages, from newborns to teenagers. It is more common in children with asthma, allergies, or a family history of breathing problems.

Symptoms

Common symptoms

• Fast breathing or panting
• Flaring of the nostrils when breathing in
• Using the muscles between the ribs or at the neck to breathe (called retractions)
• Making a whistling sound when breathing out (wheezing)
• Coughing, especially at night or with activity

Symptoms in children

• Being unusually tired or fussy
• Refusing to eat or drink
• Breathing so fast that they cannot talk or play
• Skin around the lips or fingertips turning pale or blue (a sign of low oxygen)

Symptoms in older adults

• This section is less relevant for children. In older adults, shortness of breath is often linked to heart problems or chronic lung diseases, but this article focuses on children.

Causes

Main causes

• Infections like colds, croup, bronchiolitis, or pneumonia
• Asthma (a condition where airways narrow and swell)
• Allergies to things like pollen, dust, or food
• Inhaling a small object or food piece (choking)
• Heart conditions or lung problems present from birth

Risk factors

• Premature birth or low birth weight
• A family history of asthma or allergies
• Exposure to cigarette smoke or air pollution
• Attending daycare or school where infections spread easily
• Weakened immune system

When to see a doctor

See a doctor urgently if:

• Your child has any of the emergency symptoms listed above
• Your child is breathing faster than 60 breaths per minute (for infants) or more than 40 for older children
• Your child is too breathless to eat, drink, or talk
• Your child has a bluish tint to their lips or face

Book a routine appointment if:

• Your child has repeated episodes of breathlessness, even if mild
• Your child coughs or wheezes often, especially at night or after exercise
• You suspect an allergy or asthma
• Your child has a cold that seems to be getting worse instead of better

Diagnosis

A doctor or nurse will ask about your child's symptoms, examine them, and listen to their breathing. They may also check oxygen levels with a small sensor clipped to a finger or toe. Further tests depend on what they suspect.

Tests that may be done

• Pulse oximetry – a non‑invasive sensor that measures oxygen in the blood
• Chest X-ray – to look for signs of infection or other lung problems
• Blood or mucus tests – to check for infection or allergies
• Breathing tests (spirometry) – for children old enough to blow into a tube, to diagnose asthma

What to expect at your appointment

The doctor will explain each test and why it is needed. Most tests are quick and painless. For breathing tests, a child may need to practice blowing. You can stay with your child during the visit. The doctor will discuss the results and next steps with you.

Treatment

Treatment depends on the cause. For mild infections, rest and fluids are often enough. For asthma or allergies, the goal is to reduce inflammation and open the airways. Your child's doctor will create a plan specific to their condition.

Self-care at home

• Keep your child calm and upright to help breathing
• Offer small, frequent amounts of clear fluids (water) to stay hydrated
• Use a cool‑mist humidifier or sit in a steamy bathroom to ease a cough from croup
• Avoid smoke, strong perfumes, or other triggers
• Follow the doctor's advice if your child has an asthma action plan

Medical treatments

Doctors may prescribe medications that are breathed in (inhalers) to help open the airways and reduce swelling. For infections, antibiotics or antiviral medicines may be used if needed. In hospital, oxygen or breathing treatments might be given. Your child's healthcare provider will choose the safest options based on their age and condition.

When is surgery considered?

Surgery is rarely needed for shortness of breath in children. It may be considered for certain birth defects of the heart or lungs, or if a foreign object is stuck in the airway and cannot be removed otherwise.

Living with this condition

Many children with chronic breathing problems like asthma can live full, active lives. With the right treatment plan and regular check‑ups, most symptoms can be controlled. Keep an eye on your child's breathing and know what to do if it gets worse.

Lifestyle tips

• Help your child avoid known triggers, such as smoke, dust, or pollen
• Encourage regular handwashing to reduce infections
• Make sure your child gets enough sleep – tiredness can make breathing harder
• Have an action plan written with the doctor so you know what to do in an emergency

Diet and exercise

A balanced diet rich in fruits and vegetables supports the immune system. Exercise is safe and beneficial for most children with shortness of breath – just make sure your child uses any prescribed inhaler before exercise if recommended. Talk to the doctor about which activities are best.

Mental health and emotional wellbeing

Shortness of breath can be frightening for a child. They may feel anxious about their breathing or miss out on play. Talk to your child in a calm, reassuring way. If they seem worried or withdrawn, a child psychologist or school counsellor can help.

Prevention

Not all causes can be prevented, but you can lower the risk. Keep your child away from tobacco smoke, ensure they are up‑to‑date with vaccinations, and teach good hand hygiene. For children with asthma or allergies, avoiding triggers helps prevent flare‑ups.

Vaccines

Routine childhood vaccines, such as the flu vaccine and the pneumococcal vaccine, can prevent some infections that cause breathing difficulties. Talk to your doctor about which vaccines your child needs.

Screening programmes

There are no routine screening tests for shortness of breath in healthy children. If your child has a family history of asthma or allergies, your doctor may suggest an allergy test. Newborns are often checked for heart defects that could cause breathing problems.

Complications

If left untreated

• Severe lack of oxygen can damage organs, especially the brain
• Infections can spread to the lungs (pneumonia) or become severe (sepsis)
• Asthma attacks can become life‑threatening if not treated quickly
• Chronic breathlessness can slow growth and development

Long-term outlook

Most children with shortness of breath recover fully, especially with proper care and follow‑up. For children with long‑term conditions like asthma, modern treatments help them breathe well and lead normal lives. With the right support, the outlook is very positive.
