How to tell if your baby has asthma
Doctors can treat asthma in babies with medications that help open up the airways, which are already small. While it is not always possible to prevent asthma in babies, avoiding asthma triggers, such as smoke, pet dander, pollen, and dust mite exposure, may help reduce the symptoms.
According to the Asthma and Allergy Foundation of America (AAFA), about half of all children with asthma show some signs of the condition before they reach the age of 5 years. Recognizing asthma in babies and seeking medical help can allow parents and caregivers to provide treatments that keep infants breathing well.
People should also note that babies with asthma-like symptoms may not go on to have asthma later in life.
Specific symptoms in babies
Asthma can be difficult to diagnose in infants.
Asthma can be difficult to recognize in babies because it can resemble other respiratory illnesses.
Also, a baby cannot always convey how they are feeling or that they are having difficulty trying to breathe.
Symptoms of asthma in babies include:
- blue tint to the face, fingernails, or lips, which can indicate poor oxygenation
- breathing very fast
- exaggerated stomach movements, as though the infant is using their stomach muscles to breathe
- flared nostrils
- coughing at night or even when performing routine activities
- problems eating or tiring out
- a whistling sound called wheezing that is sometimes audible from far away
Asthma can closely resemble other medical conditions in babies, such as:
- acid reflux
- cystic fibrosis
- a foreign body becoming stuck in the airway
- an upper respiratory infection
Another condition that may cause some symptoms similar to asthma in infants is laryngotracheomalacia. Babies who are born with this condition have a weakness in the cartilage just under the vocal cords.
As a result, they may breathe noisily in the upper airways and trachea, which might sound like asthma. As a baby gets older, these tissues usually become firmer and less likely to collapse.
The primary difference between asthma and some of the above illnesses is that an infant may continue to experience asthma symptoms. Asthma is a chronic condition that can affect a person throughout their life.
Even after an acute illness, they may have persistent symptoms of hyperreactive airways, meaning that the airways in their lungs become smaller and inflamed more easily than those of others. This pattern can aid doctors in making an asthma diagnosis.
Smoking while pregnant can be a risk factor for an infant developing asthma.
Risk factors that can increase the likelihood of an infant developing asthma include:
- a family history of allergies, asthma, or atopic dermatitis, the most common form of eczema
- a history of more severe symptoms with respiratory infections, such as respiratory syncytial virus
- the mother smoking during pregnancy
- premature birth
When children who are aged 6 months and younger experience acute episodes of asthma, a viral infection is usually the cause, according to the AAFA.
Diagnosis and when to see a doctor
Diagnosing asthma in babies can be challenging because the lung function tests that doctors typically perform are not as useful when babies cannot exhale or inhale on command.
As a result, a doctor may use other diagnostic methods, including:
- Administering medications to open up the airways and then seeing if a baby's symptoms improve.
- Conducting allergy testing to determine whether an older baby or toddler is sensitive to any common allergic triggers, such as dust mites, mold, pet dander, or pollen.
- Ordering imaging studies, such as X-rays, to examine an infant's lungs.
Asthma is a chronic condition with no cure. However, many babies who have asthma-like symptoms, such as wheezing, do not go on to have asthma later in life. This is another reason why diagnosing asthma in babies can be difficult. As a result, a doctor may not definitively diagnose a baby with asthma until later in life.
Sometimes, a doctor will refer a child to an allergy specialist or to a lung specialist called a pulmonologist for further testing and treatment.
Treatments and remedies
Babies can receive asthma medication through an inhaler with a mask attachment.
Inhalers and nebulizer treatments are the medication delivery systems for asthma.
Even young infants can sometimes receive asthma medications through an inhaler that uses an extra attachment called a spacer and an infant-sized mask.
A nebulizer, which people sometimes refer to as a breathing machine, delivers liquid medication in combination with compressed air. The result is a medicated mist that a baby breathes into their airways.
Wearing the infant-sized mask can help the baby breathe in the medicine. A doctor will recommend how many times per day a baby should receive their asthma medicine.
Some of the medications that require an inhaler or a nebulizer for delivery may be short-acting drugs, such as albuterol (Ventolin). This medication helps quickly open up the airways to make it easier to breathe. A doctor may also prescribe long-acting medications containing steroids that help reduce inflammation and also open up the airways.
In addition to prescription medications, a doctor may recommend taking steps to reduce allergens that commonly trigger asthma symptoms. Examples include smoking, pet dander, pollen, and dust mites.
Parents and caregivers can protect their child from asthma triggers in the home by:
- Washing bed linen and cloth toys at least once a week in water that is 130ºF or hotter to kill dust mites.
- Vacuuming at least once each week to remove excess dust.
- Preventing cigarette smoke from entering the home or car. If a parent or caregiver does smoke outside the home, they should change their clothes when they come back in.
- Preventing pets from going into the bedroom.
- Using air purifiers that have a high-efficiency particulate air (HEPA) filter to reduce the amount of animal dander and dust in the home.
- Covering an infant's crib mattress in an allergy-proof casing. These casings have tight weaving that can prevent dust mites from entering the mattress.
A parent or caregiver may also wish to talk to their child's pediatrician before introducing potentially allergenic foods, such as peanuts, cow's milk, eggs, and wheat, although it is rare for food allergies to cause asthma in babies.
In cases where there is a family history of food sensitivities, it may be beneficial to introduce these foods slowly and in small amounts to ensure that a child does not have an allergic reaction that causes breathing problems.
Wheezing and breathing problems in babies can be a significant concern. As a baby's airways are already small, conditions such as asthma can make it especially difficult to breathe.
If a person has concerns about their baby wheezing or showing other potential asthma signs, they should talk to their child's doctor as soon as possible.
