What Is Asthma?
Asthma is a common long term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm.
It is a disease of the respiratory tract, which is often lifelong.
Asthma can be minor or it can interfere with daily activities. In some cases, it may lead to a life-threatening attack.
Asthma may cause difficulty breathing, chest pain, cough and wheezing. The symptoms may sometimes flare-up.
Asthma can usually be managed with rescue inhalers to treat symptoms (salbutamol) and controller inhalers that prevent symptoms (steroids). Severe cases may require longer-acting inhalers that keep the airways open (formoterol, salmeterol, tiotropium), as well as inhalant steroids.
Asthma is a chronic disease of the airways that makes breathing difficult With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs. This results in asthma symptoms, including coughing, wheezing, shortness of breath, and chest tightness.
If it is severe, asthma can result in decreased activity and inability to talk. Some people refer to asthma as “bronchial asthma.”
Asthma is thought to be caused by a combination of genetic and environmental factors. What is asthmaEnvironmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry.
There is no cure for asthma.Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids.
