What Initially Causes Sinusitis?

• Physical blockage in the nose and sinuses - A deviated septum, enlarged turbinates (anatomical structures in your nose), or tumors can block critical drainage pathways and cause bacteria to build up.
• Inflammatory and infectious causes - Viral and fungal infections, as well as allergies and polyps, can cause inflammation leading to chronic sinusitis.
• Developmental disorders - Cystic fibrosis, for example, causes excess mucus that harbors bacteria and can lead to a chronic sinus infection.
