<s>[INST] What causes asthma symptoms or an asthma attack? [/INST] Some causes of symptoms (triggers) are common to all people with asthma, and some are more individual, especially allergens. There are very big differences between people in how easily and how severely they react. The severity of the symptoms or an attack can differ in the same person at different times, and treatment can also be more or less effective.Your asthma does not stay the same, but changes over time, and every person with asthma has good days and bad days (or longer periods). However, if asthma is properly treated, there can also be long periods without symptoms or attacks. Source: Ginasthma. Link: https://ginasthma.org/about-us/faqs/. Field: Lung Disease.
