What Is Childhood Asthma?
If your child has asthma, their lungs and airways can easily get inflamed when they have a cold or are around things like pollen. The symptoms may make it hard for your child to do everyday activities or sleep. Sometimes, an asthma attack can result in a trip to the hospital.
There’s no cure for asthma in children, but you can work with your child’s doctor to treat it and prevent damage to their growing lungs.
Signs and Symptoms of Childhood Asthma
Not all children have the same asthma symptoms. A child may even have different symptoms from one episode to the next. Signs and symptoms of asthma in children include:
- A cough that doesn’t go away (which may be the only symptom)
- Coughing spells that happen often, especially during play or exercise, at night, in cold air, or while laughing or crying
- A cough that gets worse after a viral infection
- Less energy during play
- Avoiding sports or social activities
- Trouble sleeping because of coughing or breathing problems
- Rapid breathing
- Chest tightness or pain
- Wheezing, a whistling sound when breathing in or out
- Seesaw motions in their chest (retractions)
- Shortness of breath
- Tight neck and chest muscles
- Feeling weak or tired
- Trouble eating, or grunting while eating (in infants)
Your child's doctor should check out any illness that makes it hard for them to breathe.
Experts sometimes use the terms “reactive airways disease” and “bronchiolitis” when talking about wheezing with shortness of breath or cough in infants and toddlers. Tests may not be able to confirm asthma in children younger than 5.
When to get emergency care:
A severe asthma attack needs medical care right away. Watch for these signs:
- Stopping in the middle of a sentence to catch a breath
- Using stomach muscles to breathe
- A belly that sinks in under their ribs when they try to get air
- Chest and sides that pull in as they breathe
- Widened nostrils
- Fast heartbeat
- Sweating more than usual
- Chest pain
Causes and Triggers of Childhood Asthma
Common triggers include:
- Airway infections. This includes colds, pneumonia, and sinus infections.
- Allergens. Your child might be allergic to things like cockroaches, dust mites, mold, pet dander, and pollen.
- Irritants. Things like air pollution, chemicals, cold air, odors, or smoke can bother their airways.
- Exercise. It can lead to wheezing, coughing, and a tight chest.
- Stress. It can make your child short of breath and worsen their symptoms.
Childhood Asthma Risk Factors
Asthma is the leading cause of long-term illness in children. It affects about 7 million kids in the United States. Those numbers have been going up, and experts aren’t sure why.
Most children have their first symptoms by age 5. But asthma can begin at any age.
Things that can make a child more likely to have asthma include:
- Nasal allergies (hay fever) or eczema (allergic skin rash)
- A family history of asthma or allergies
- A lot of respiratory infections
- Low birth weight
- Exposure to secondhand tobacco smoke before or after birth
- African American or Puerto Rican descent
- Being raised in a low-income environment
Childhood Asthma Diagnosis
Your child’s asthma symptoms may be gone by the time you get to the doctor’s office. You have an important role in helping your doctor understand what’s going on. A diagnosis will include:
- Questions about medical history and symptoms. Your doctor will ask about any breathing problems your child may have had, as well as any family history of asthma, allergies, eczema, or other lung disease. Describe your child's symptoms in detail, including when and how often they happen.
- Physical exam. Your doctor will listen to your child's heart and lungs and look in their nose or eyes for signs of allergies.
- Tests. Your child might get a chest X-ray. If they’re 6 or older, they may have a simple lung test called spirometry. It measures the amount of air in your child’s lungs and how fast they can blow it out. This helps the doctor find out how severe their asthma is. Other tests can help find asthma triggers. They may include allergy skin testing, blood tests (IgE or RAST), and X-rays to tell if sinus infections or gastroesophageal reflux disease (GERD) is making asthma worse. A test that measures the level of nitric oxide (eNO) in your child’s breath can also point to inflamed airways.
Childhood Asthma Complications
When it’s not under control, asthma can cause problems like:
- Severe attacks, sometimes leading to ER visits or stays in the hospital
- Missed school and other activities
- Stress, anxiety, and depression
- Delays in growth or puberty
- Damaged airways and lung infections
Childhood Asthma Treatment
Avoiding triggers, using medications, and keeping an eye on daily symptoms are the best ways to control asthma in children of all ages.
There are two main types of asthma medications:
- Quick-relief medications help with sudden symptoms. Your child will take them for fast help during an asthma attack.
- Long-acting medications prevent airway inflammation and keep asthma under control. Your child will probably take them every day.
Based on your child's history, their doctor will come up with an asthma action plan and give you a copy of it. This plan describes when and how they should use asthma drugs, what to do when asthma gets worse, and when to seek emergency care. Make sure you understand this plan, and ask the doctor any questions you may have.
Give copies to your child’s caregivers and teachers so they’ll know what to do if the child has an asthma attack away from home.
Many asthma medications contain steroids, which could have side effects. They can irritate your child’s mouth and throat. Some research shows that over time, they might cause slow growth, bone problems, and cataracts. After your child takes them, their body might not be able to make as many natural steroids. But without treatment, asthma can lead to health problems and hospital visits. You and your doctor should talk about the pros and cons of medication when you make an asthma action plan.
Childhood Asthma Medication
Children under 4 may get lower doses and take their medications through an asthma nebulizer. This device changes the medicine from a liquid to a mist that your child breathes into their lungs. The doctor will tell you how often to give these breathing treatments. It’s usually up to four times a day, about 10 to 15 minutes at a time. To use the nebulizer:
- Wash your hands.
- Put the medicine in the nebulizer.
- Connect the tubes from the compressor to the base.
- Attach the mouthpiece or mask.
- Turn the compressor on and watch for a light mist to come from the nebulizer.
- Put the mask on your child’s face, or put the mouthpiece in their mouth and have them close their lips around it.
- Have them breathe in and out until their treatment time is up.
- Turn the nebulizer off when the medicine is gone.
- Have your child cough to clear out any mucus.
There are guidelines for managing asthma in children up to age 4. This includes the use of quick-relief medications (like albuterol) for off-and-on symptoms. A low dose of an inhaled steroid, cromolyn, or montelukast (Singulair) is the next step up. After age 4, the focus shifts from symptom control to disease management. If your child’s asthma is under control for at least 3 months, their doctor may lower their treatment.
Instead of a nebulizer, older kids may be able to use a metered dose inhaler (MDI) with a spacer. A spacer is a chamber that attaches to the inhaler and holds the burst of medication. This lets your child breathe the medication into their lungs at their own pace. To use an inhaler with a spacer:
- Wash your hands.
- The first time you use it, prime the inhaler by spraying it 4 times into the air.
- Put the inhaler into the opening at the end of the spacer.
- Shake it for 10 seconds.
- Have your child turn their head to the side and breathe out.
- Have them close their mouth around the mouthpiece of the spacer.
- Tell them to take a slow deep breath.
- Make them hold it in and count to 10.
- Have them slowly breathe out.
- If your doctor prescribes two puffs of medicine, wait 1 minute after the first puff and then do it all again.
- Help them rise their mouth, brush their teeth, or get a drink of water.
Avoiding Childhood Asthma Triggers
To prevent asthma attacks or to keep them from getting worse, focus on known triggers with steps like these:
- Don’t let anyone smoke in your home or car.
- Clean bedding and carpets often to fight dust mites.
- Keep pets out of your child’s bedroom. An air filter can help with allergens.
- Get regular pest control to avoid cockroaches.
- Fix leaks and use dehumidifiers to prevent mold.
- Don’t use scented cleaning products or candles.
- Check daily air quality reports in your area.
- Help your child stay at a healthy weight.
- If they have heartburn, keep it under control heartburn.
- If exercise is a trigger, your child’s doctor might give them medicine to help keep their airways open during activity.
- Make sure they get a flu shot every year.
Childhood Asthma Outlook
There’s no cure for asthma, but your child can learn to control it. They should be able to:
- Prevent long-term symptoms
- Go to school every day
- Avoid asthma symptoms at night
- Take part in daily activities, play, and take part in sports
- Avoid urgent visits to the doctor, emergency room, or hospital
- Use and adjust medications to control symptoms with few or no side effects
If they have trouble meeting all of these goals, ask their doctor for advice.
There’s a lot that experts don’t know about infant lung function and asthma. But they believe that a child is more likely to be diagnosed with asthma after the age of 7 if they’ve had multiple wheezing episodes, have a mother with asthma, or have allergies.
Once a child’s airways become sensitive, they stay that way for life. But about 50% of children see a sharp drop in asthma symptoms once they reach their teens. It may seem they’ve outgrown their asthma, but some will have symptoms again as adults. There’s no way to predict what may happen with your child.
By learning about asthma and how to control it, you take an important step toward managing your child's condition. Work closely with their care team to learn all you can about asthma, how to avoid triggers, what medications do, and how to give treatments.
