Sinusitis can be caused by both bacteria and fungus. A bacterial infection usually occurs after a cold or virus when the congestion in the nose stops drainage from the sinuses. This fluid buildup in the sinuses breeds bacteria and may cause sinusitis. However, it has recently been proven that sinusitis can also be an immune response to a fungus.⁵ In fact, the Mayo Clinic recently published a study which found that over 90% of sinus infections are fungal rather than bacterial. Thus, antibiotics (which are the most commonly prescribed treatment) are completely ineffective (not to mention damaging to the immune system) over 90% of the time.^10,6

For those with allergies, sinusitis can be caused by irritants, such as smoke and pollution, and allergens such as dust, mold, and pollen.^1,7 Structural problems in the nose from a break, a deviated septum, or polyps can also block the sinuses and lead to an infection.⁸ Overuse of decongestant sprays is also a cause of sinusitis.² In rare cases, sinusitis can be caused by an abscessed tooth. Sinusitis can also develop because of tooth or gum infections, nosebleeds, an aging immune system, or dryer nasal secretions that do not drain well.¹

While acute sinusitis is most often brought on by an acute upper respiratory infection—such as the common cold, which is caused by a virus²—as stated above, the Mayo Clinic has done some pioneering research which demonstrates that most cases of chronic sinusitis are actually the result of a fungal infection, the most prevalent of which may be Candida albicans.^6,9,10 To take an online self-assesment for Candida now, click here.

Research has also shown that sinusitis can be caused by exposure to toxic mercury vapor, whether from first- (from the presence of "silver" fillings in your mouth) or second-hand exposure.¹¹
