What is asthma?

Asthma is a long-term disease of the airways in the lungs. Its symptoms are caused by inflammation, which makes the airways red, swollen, narrower and extra-sensitive to irritants. This leads to recurrent attacks of wheezing, breathlessness, chest tightness and coughing. Mild attacks can settle down without treatment, but treatment usually helps them to resolve more quickly. Appropriate treatment can also reduce the risk of further attacks.
