There are no immunizations or other treatments that can prevent asthma, but some measures can help to prevent flare-ups of asthma. Once an individual has been diagnosed with asthma, the healthcare provider will recommend a treatment plan. The plan usually includes identifying and avoiding any triggers and taking medicines. By following the treatment plan, an individual can minimize asthma flare-ups.
Asthma is characterized by periodic flare-ups. Between flare-ups, many people will have a return to normal breathing. Over many years, this pattern can continue without the person getting dramatically worse. In some people, asthma flare-ups increase as they get older.
In people with more severe asthma, long-term inflammation can lead to permanent changes in the airways. This is called airway remodeling. The actual structure of the airway walls can change, causing blockage that can't be completely reversed with treatment.
Some children outgrow asthma. Sometimes symptoms stop and asthma disappears as they grow up.
Asthma is not contagious and poses no risk to others.
