What is the expected duration of Asthma

Asthma is a chronic disease that affects millions of people worldwide. In a person with asthma, the small airways in the lung become constricted and inflamed due to hypersensitivity towards certain factors (pet dander, dust mites, smoke, pollens and certain weather conditions). Read on to know how long does asthma last?

Asthma Flare-ups


Acute asthma attacks can be precipitated by certain trigger factors and this hypersensitivity can persist for an extended period of time. During an "asthma episode," or an "asthma attack," the symptoms develop (or increase in severity) due to the obstruction of the normal flow of air through the air passages which makes breathing difficult. In some people, asthma symptoms and acute episodes can last for a lifetime, whereas in others the acute attacks and symptoms may be controlled for a long time but the sensitivity can persist and an acute episode of asthma symptom can occur anytime. Symptoms of an acute episode include chest tightness, shortness of breath or increasing difficulty in breathing, coughing and wheezing.




In most cases, it is not possible to avoid all the possible trigger factors but there are certain preventative measures and medications that can help you to control asthma symptoms.

  • Preventive measures include avoiding outdoor activities on the days when pollen in the air is expected to be high, or when it is dusty. Wear a protective mask when you go out to reduce exposure to allergens and take measures to control exposure to allergens at home and follow your doctor’s recommendations regarding medications.
  • Preventative and controller medications are very important in order to control asthma attacks and other symptoms of asthma. Inhaled and oral corticosteroids, long acting beta2 agonists, cromolyn sodium and nedocromil sodium, and anti-leukotriene agents (montelukast and zafirlukast) may be prescribed to prevent and control symptoms of asthma. If you are an asthmatic you should carry your fast-acting or rescue inhaler (salbutamol inhaler) at all times. During an acute episode, the medication relaxes the airways and reduces symptoms immediately.

Experts suggest that if you are asthmatic, you should follow your doctor’s recommendations regarding medication and prevention to avoid repeated flare ups of symptoms. And even if you have been asymptomatic for a long time, follow preventive measures to avoid trigger factors (pet dander, dust mites, smoke, pollens and certain weather conditions) as the risk of flare ups lasts for the lifetime.
