Air travels in and out of the lungs through bronchial tubes. Asthma is a chronic inflammation of these tubes. This inflammation causes airways to narrow. This makes it hard to breath. There are different degrees of asthma. Some people may have very mild asthma with rare flare-ups. Others may have a severe, constant asthma.
Asthma is the most common chronic disease found in children. If your child is having trouble breathing, call 911 immediately. This is a potentially serious condition that needs immediate medical attention.
If it is not an emergency, but you suspect your child may have asthma, contact your doctor. With proper treatment, asthma can be controlled.
The exact causes of asthma are unknown. It is thought that a mix of genes and environment causes asthma. Possible causes include:
Certain conditions are known to trigger an asthma attack. These include:
These factors increase your child’s chance of asthma. Tell your doctor if your child has any of these risk factors:

Talk with your child’s doctor about the best plan for your child. You and your child's doctor should also create an asthma action plan. This is a plan your child will follow to help control his asthma and handle asthma attacks. Treatment will vary based on how many asthma episodes your child has and any specific symptoms. Treatment options include the following:
Medications used to treat asthma fall into one of two categories:
Quick relief medications—usually given as inhalers
Long-term control:
Your child’s asthma may be triggered by allergies. In this case, your doctor may recommend allergy shots. These shots are very small amounts of an allergen injected into the skin. Over time your child will react less to the specific allergen(s). With less triggers the asthma also decreases.
There are no known ways to prevent your child from developing asthma. However you can help your child reduce his or her chance of triggering an asthma attack, by taking the following steps:
