Things That Causes Sinusitis (Sinus Infection), Note Them!

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain

Sinus infections or sinusitis may be caused by anything that interferes with airflow into the sinuses and the drainage of mucus out of the sinuses. The sinus openings (ostea) may be blocked by swelling of the tissue lining and adjacent nasal passage tissue.

Symptoms
There are many signs and symptoms of sinusitis and sinus infections. The following is a summary of predominant ones that may occur. Most patients have several signs and symptoms at the same time such as -
◾Thick, discolored discharge from the nose or drainage down the back of the throat (postnasal drainage)
◾Nasal obstruction or congestion, causing difficulty breathing through your nose
◾Pain, tenderness and swelling around your eyes, cheeks, nose or forehead
◾Reduced sense of smell and taste in adults or cough in children


Risk factors
You'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
◾Asthma, which is highly connected to chronic sinusitis
◾Aspirin sensitivity that causes respiratory symptoms
◾An immune system disorder, such as HIV/AIDS or cystic fibrosis
◾Hay fever or another allergic condition that affects your sinuses
◾Regular exposure to pollutants such as cigarette smoke

Complications
Chronic sinusitis complications include:

  • Meningitis. This infection causes inflammation of the membranes and fluid surrounding your brain and spinal cord.
  • Other infections. Uncommonly, infection can spread to the bones (osteomyelitis) or skin (cellulitis).
  • Partial or complete loss of sense of smell. Nasal obstruction and inflammation of the nerve for smell (olfactory nerve) can cause temporary or permanent loss of smell.
  • Vision problems. If infection spreads to your eye socket, it can cause reduced vision or even blindness that can be permanent.

Causes Of Sinusitis
Sinusitis is usually the result of a cold or flu virus spreading to the sinuses from the upper airways. Only a few cases are caused by bacteria infecting the sinuses.
An infected tooth or fungal infection can also occasionally cause the sinuses to become inflamed.
It's not clear exactly what causes sinusitis to become chronic (long-lasting), but it has been associated with:
◾Allergies and related conditions, including allergic rhinitis,
◾Asthma and hay fever
◾Nasal polyps (growths inside the nose)
◾Smoking
◾Weakened immune system
◾Tumors or growths also can block the sinuses if they are near the sinus openings.


Dehydration , disease, drying medications, and lack of sufficient humidity can cause sinusitis or sinus infection.The drainage of mucous from the sinuses can also be impaired by thickening of the mucous secretions, by decrease in hydration (water content) of the mucous brought on by disease (for example, cystic fibrosis), drying medications ( antihistamines ), and lack of sufficient humidity in the air.
