<s>[INST] What is asthma? [/INST] 
Asthma is a reversible periodic disease of the airways. This means that the airways clamp down and get very sensitive, causing a variety of symptoms such as shortness of breath, cough and wheezing.

Some people’s asthma is caused by allergies and the resulting inflammation in their airways. For some with non-allergic asthma, their bodies do not metabolize certain chemicals properly and so they have a buildup of these chemicals in their body that then cause their asthma symptoms. Others have asthma due to inflammatory changes within their own bodies Source: Banner Health. Link: https://www.bannerhealth.com/services/asthma/faqs. Field: Lung Disease. Disease: Asthma </s>
