<s>[INST] I'm Exposed to Substances at Work That Worsen my Asthma. What Can I Do to Prevent This? [/INST] Generally, if asthma symptoms are worse on days that you work, and improve when you are at home for any length of time (weekends, vacations) and then reoccur when you return to work, occupational asthma should be considered. This may be allergy related or an irritant reaction from exposure to triggers in the workplace. Identification and avoidance of triggers and starting an appropriate medical treatment plan will help to stabilize your airways and decrease symptoms. Ask your doctor to refer you to a specialist, preferably an allergist, to begin the correct treatment program. Source: webMD. Link: https://www.webmd.com/asthma/asthma-faq. Field: Lung Disease.
