Overview
Asthma – What is it? Symptoms of asthma What is work-related asthma? How common is work-related asthma? What substances trigger asthma? How asthma is treated? Clues that suggest asthma may be work-
related What YOU can do if you have asthma
Asthma – What is It? Asthma is a chronic
lung disease that obstructs airflow
The obstruction is reversible
It involves difficulty in breathing due to – Inflammation (swelling)– Mucus in the airways– Tightening of muscles
around the airways
Symptoms of asthma
Coughing
Wheezing, a whistling sound
Shortness of breath
Chest tightness
Sneezing & runny nose
Itchy and inflamed eyes
What is work-related asthma?
Pre-existing asthma that is triggered or made worse by exposure to one or more substances in the work-environment
OR
Asthma that is caused by exposure to substances in the work-environment
Signs and symptoms are the same for asthma and work-related asthma
How common is asthma?
About 20 million Americans currently have asthma– About 8% of Utah adults have asthma
Up to 20% of all adult asthma cases maybe work-related asthma
Of those diagnosed with work-related asthma:– 20-27% are individuals with pre-existing asthma
who react to substances in the workplace– Up to 80% develop asthma due to work-place
exposures
What substances trigger asthma?
Type of Substance ExamplesAir pollutants, including dusts, smoke, mists & fumes
Diesel exhaust; tobacco smoke; mineral, rock, coal, & wood dusts; gases; fumes & vapors from aerosol agents, chemicals, cleaning materials, solvents, paints, welding & from heating & cooling metals quickly
Pollens, mites & molds Trees, flowers, weeds, hay, plants
Animal dander Birds, cats, dogs
Medications Aspirin, anti-inflammatory drugs
Foods Egg, wheat, nuts
Can asthma be cured? Asthma can be controlled (but not cured)
by:– Avoiding triggers or reducing exposure to
triggers– Using medication to control symptoms
Medications - generally two types are used – Controller or long-term drugs
• Taken to prevent excess production of mucus & to reduce the inflammation and constriction of airway muscles
– Rescue or quick-relief drugs• Taken to relax muscles around the airways to improve
breathing
Poorly controlled asthma leads to:
Increased visits to – Doctor, Urgent Care
Clinic or Hospital ERHospitalizationsLimitations in daily
activitiesLost work daysLower quality of
lifeDeath
What clues suggest that asthma is work-related?
Do symptoms:– Occur only at work
or regularly after a work-shift?
– Improve on weekends or vacations?
– Increase over the course of the work week?
– Improve after changes in the work environment?
Information to share with doctor
Discuss your symptoms.– When do they occur?– How often do they occur?– Time of day or week that
symptoms are worse– Times you feel better– Identify
• Substances in the work-place to which you are exposed
• Current and previous jobs, hobbies, and smoking habits that may affect your lungs
What YOU can do if you have asthma?
Identify and minimize contact with your asthma trigger(s)
Understand and take asthma medications as prescribed
Recognize early signs that your asthma is getting worse
Know what to do when your asthma is getting worse
