Researchers continue to learn what causes asthma. It is not entirely understood. The following things play a part:
Genetics. Asthma runs in families.
Allergies. Some allergies are more common in people with asthma. And, allergies also tend to run in families.
Respiratory infections. Infants and young children who have some respiratory infections are more likely to have long-term lung problems.
Environmental factors. Irritants, like pollution and allergens, are known to cause asthma.
Triggers are those things that cause asthma symptoms to get worse or asthma flare-ups. Each child has different triggers. A very important part of asthma management is identifying and then trying to avoid triggers. Asthma triggers include:
Allergens, such as pollen, dust, and pets
Upper respiratory infections, such as colds or the flu.
Inhaled irritants, such as secondhand smoke.
Certain weather conditions, such as cold air.
Exercise or physical activity.
Emotion, such as crying, laughing, or yelling.
How asthma will affect a child throughout his or her lifetime varies.
Many infants and toddlers may wheeze when sick with a viral illness, such as cold or flu. However, most of these children don't get asthma later in life.
Some children with persistent wheezing and asthma get better during the teenage years.
About half of the children who have asthma at a young age appear to "outgrow" it, although asthma symptoms may reappear later in life.
Exercise, such as long-distance running, may trigger a flare-up in many children with asthma. However, with proper management, a child with asthma can fully participate in most sports. Aerobic exercise actually improves airway function by strengthening breathing muscles. Some tips for exercising with asthma include the following:
Teach your child to breathe through the nose and not the mouth to warm and humidify the air before it enters the airways.
During cold weather, have your child wear a scarf over his or her mouth and nose to warm inhaled air.
Give your child asthma medicine before exercising, as recommended by your child's healthcare provider. If your child is not already on controller medicine and he or she exercises daily, the provider may recommend daily controller medicine.
Have your child carry his or her quick-relief inhaler medicine.
Some children with asthma may need to take their medicines during school hours. It's important that you and your child work with his or her healthcare provider and school staff to meet the child's asthma treatment goals. Laws about students carrying rescue inhalers vary by state. Make sure you understand the laws and that your child knows when and how to use their inhaler. For the best asthma care for your child at school, the American Academy of Allergy, Asthma, & Immunology recommends the following:
Meet with teachers and other relevant school staff to inform them about your child's condition, special needs, and asthma management plan.
Educate school personnel on your child's asthma medicines and how to help during an asthma flare-up.
Ask school staff to treat your child as normal as possible when the asthma is under control.
Before starting a physical education class or a team sport, make sure the teacher or coach understands that exercise can trigger asthma symptoms.
Talk with teachers and school administrators about indoor air quality, allergens, and irritants in the school.
Ensure your child's emotional well-being by reassuring that asthma doesn't have to slow him or her down or make him or her different from other children.
Be honest with your child about asthma. Remember, as your child grows, that independence is an important goal. Children with asthma don't want to be different, yet they need guidance and supervision.
Toddlers. This age group relies completely on the parents. These children understand little about asthma. The most important factor with this age group is to try to make medication time a fun one, while stressing the importance of taking the medications. Let the children assist in any way possible.
School-age. These children have an increased ability to understand asthma. They should be taught about their medicines and how to avoid their triggers. They should begin to monitor their own symptoms.
Adolescents. Often, adolescents resist taking chronic medicines, don't like restrictions, and don't want to be different. Involve adolescents in every aspect of asthma management. They should help with goal setting and help decide which medicines work best. An asthma care "contract" can be used. It should allow for self-care while allowing overall parental supervision.
Having asthma doesn't mean having less fun than other adolescents. It is important for your adolescent to tell his or her friends about his or her triggers.
Always consult your child's provider if you or your child has questions or concerns.
