Occupational asthma treatment in Fresno & Merced
Occupational asthma is asthma caused or worsened by exposure to substances at work. Sierra Allergy Asthma and Sinus Center team helps identify your triggers and provide personalized care so you can breathe easier and stay healthy on the job.

- Shortness of breath, especially with activity
- Symptoms that improve on weekends or vacation
- Fatigue or difficulty sleeping due to breathing issues
Who is at risk of occupational asthma?
You may be at higher risk if you work in industries with exposure to:
- Dusts and particles (flour, wood, grain, cotton, or latex)
- Fumes and chemicals (cleaning products, isocyanates, ammonia, solvents)
- Gases or vapors (from plastics, paint, adhesives, or industrial equipment)
- Mold or animal dander (in farming, labs, or veterinary clinics)
- Smoke or combustion products (firefighters, welders, mechanics)
Even low-level, repeated exposures can lead to symptoms over time.

How we identify occupational asthma
Sierra Allergy Asthma and Sinus Center takes a detailed and supportive approach to diagnosing occupational asthma:
Symptom & Medical History Review
We begin by understanding your symptoms, when they occur, and how they relate to your work routine.
Lung Function Testing
Tests like spirometry or peak flow monitoring help us measure how well your lungs are working.
Bronchodilator Response Check
We test how your breathing improves after using medication, which helps confirm an asthma diagnosis.
Allergy Testing
If allergens like mold, latex, or animal dander are involved, we perform allergy testing to pinpoint them.
Workplace Exposure Assessment
We carefully review your job environment and tasks to identify potential asthma triggers.
Accurate diagnosis helps you get the right treatment and protects your long-term health.

- Rescue inhalers (like albuterol) for immediate relief
- Daily controller medications to reduce inflammation
