What is asthma in children?
Asthma is a long-term (chronic) lung disease that causes your child's airways to become sensitive to certain things (triggers). Several things happen to the airways when a child is exposed to triggers:
- The lining around the airways swell.
- The muscles around the airways tighten.
- The airways make more thick mucus than normal.
All of these things will cause the airways to narrow. This makes it difficult for air to go in and out of your child’s lungs and causes the symptoms of asthma.
What causes asthma in a child?
The exact cause of asthma is not known. Researchers think it is partially passed down through families. But it can also be caused by many other things such as the environment, infections, and chemicals.
Which children are at risk for asthma?
A child is more likely to get asthma if he or she:
- Is age 5 to 17 years old
- Has family members with asthma
- Has allergies
- Is around tobacco smoke
- Is around air pollution
- Has another health problem such as sinus problems and being overweight
What are the symptoms of asthma in a child?
Symptoms can occur a bit differently in each child. Children with asthma have times when they have few, if any symptoms. They also have times when symptoms flare up. Symptoms may include:
- Cough that is either constant or comes and goes
- Wheezing or whistling sound that is heard while your child is breathing
- Trouble breathing or shortness of breath while your child is active
- Chest tightness
- Cough at night
- Noisy breathing
The symptoms of asthma can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
How is asthma diagnosed in a child?
To diagnose asthma, your child’s healthcare provider may recommend these tests:
- Spirometry. A spirometer is a device used to check lung function. It can be done in young children, including infants.
- Peak flow monitoring. A peak flow meter is used to measure the amount of air a child can blow out of the lungs. This measurement is very important in checking how well your child’s asthma is being controlled.
- Chest X-rays. This diagnostic test uses invisible energy beams to make images of internal tissues, bones, and organs on film.
- Allergy tests. Allergy tests can show if your child has allergies that may be causing or worsening asthma.
How is asthma treated in a child?
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Your child’s healthcare provider may refer you to a pulmonologist. This is a doctor with special training to treat lung conditions. Your child may also be referred to an asthma and allergy specialist. Your child’s treatment is based on how severe his or her symptoms are and how easily they are controlled. Treatment includes finding triggers and ways to avoid them. It will also include medicines.
Asthma medicines include:
- Bronchodilators. These medicines are used to help open the narrowed airways. They may relieve coughing, wheezing, shortness of breath, or difficulty breathing.
- Anti-inflammatory medicines. These medicines help decrease the inflammation in the airways.
- Anti-leukotrienes. These medicines help decrease the narrowing of the airways. These are usually given by mouth.
- Immunotherapy. This can be used for severe asthma attacks in children ages 12 and older.
What are the complications of asthma in a child?
Asthma that is not well controlled may cause:
- Severe asthma attacks
- Lasting damage to the airways
- Increased time in the hospital or the emergency department
- Missed school or other activities
What can I do to prevent asthma in my child?
Asthma can’t be completely prevented. There are steps you can take to reduce the chance of your child developing asthma. They include:
- Avoiding secondhand smoke
- Avoiding air pollution
In most children, asthma flare-ups can be prevented by:
- Avoiding known triggers
- Carefully managing symptoms
- Taking medicines as instructed
How can I help my child live with asthma?
You can help manage your child’s asthma by:
- Finding out your child’s triggers and keeping him or her away from them.
- Giving your child medicine as directed to prevent symptoms.
- Creating and keeping an Asthma Action Plan.
- Closely watching asthma signs and symptoms to know when they are getting worse.
- Knowing what to do when asthma gets worse.
Work with your child’s healthcare provider to find the best way to take care of your child’s asthma. There are guidelines for children from newborn to age 4, ages 5 to 11, and ages 12 and older.
The more information a person with asthma has, the better the asthma can be controlled.
When should I call my child’s healthcare provider?
Call your child’s healthcare provider if your child’s symptoms are not well-controlled. For example, your child is waking at night with symptoms or is having trouble with daily activities.
Call your child’s healthcare provider or get medical help right away if your child has severe symptoms. These severe symptoms can include trouble:
