Causes of sinusitis

Sinusitis is can be caused by any of the following:

Allergy

One of the most common causes of sinusitis is allergy. When an allergen (dust) enters the sinus passages, usually through inhalation this can cause an inflammation of the nasal mucous membranes which line the nasal passages. These inflamed nasal mucosa block proper drainage of the sinuses and this blockage encourages (usually) bacterial infection, resulting in sinusitis.

Chemical irritation

Any type of chemical can potentially irritate the nasal passages and cause an inflammation of the sinuses, to lead to sinusitis. The most commonly inhaled chemical irritants that can cause sinusitis are: cleaning products, perfumes, pest control chemicals

Dental infection

Any type of infection of any part of the teeth can be an underlying factor which can cause the symptoms of sinusitis. It is important to appropriately treat this cause of sinusitis as a dental infection can cause many complications.

Infection by virus or bacteria

The most common cause of sinusitis is due to a viral infection, usually during a cold or flu infection. The virus can infect and inflame the sinus passages and cause sinusitis symptoms. A less common cause of infection is a bacterial infection of the sinuses, which is due mainly because of the blockage of mucous that provides a perfect environment for infection.
