Unusual Asthma Symptoms
Health Conditions That May Worsen Asthma continued...
The reasons behind the association of asthma and sinusitis include:
- Sinusitis may activate a "sinobronchial reflex" and worsen asthma
- The infected mucus from the sinuses may drain into the bronchial tubes and cause inflammation that results in bronchitis (sinobronchitis). This can worsen asthma.
