Risk factors
By Mayo Clinic staffYou're at increased risk of getting chronic or recurrent sinusitis if you have:
- A nasal passage abnormality, such as a deviated nasal septum or nasal polyps
- Aspirin sensitivity that causes respiratory symptoms
- A medical condition, such as cystic fibrosis or chronic obstructive pulmonary disease (COPD)
- An immune system disorder, such as HIV/AIDS or cystic fibrosis
- Hay fever or another allergic condition that affects your sinuses
- Asthma — about 1 in 5 people with chronic sinusitis have asthma
- Regular exposure to pollutants such as cigarette smoke
