The exact cause of asthma is not known, but experts believe it’s due to a combination of environmental and genetic factors. Asthma runs in families, so it's very common if one family member has asthma, that others will have it.

Asthma symptoms include coughing, wheezing, shortness of breath and chest tightness.

Many children who have asthma will outgrow the condition, although in more severe cases, it can be a lifelong condition.

Your physician may perform lung (pulmonary) function tests such as spirometry or peak flow to diagnose your asthma.

Asthma treatment includes using a quick-relief inhaler, such as albuterol, during a flare-up. Long-term asthma control medications such as inhaled corticosteroids or leukotriene modifiers are often required to manage your condition.
