What is the reason for Sinusitis?

Sinusitis is a kind of swelling or inflammation of the sinus tissue over the forehead. The sinuses occur
in the four cavities (spaces) in the skull. They are linked together by thin canals. The sinuses produce
thin mucus that drains via the nasal canals. This drainage helps to keep the nose clean and clear of
bacteria. Sinuses, which ordinarily contain air, can get clogged and fill with fluid. Bacteria develop in
the environment and produces infection (bacterial sinusitis).
Anyone can get a sinus infection. Sinusitis is common in patients who have nasal allergies, nasal
polyps, asthma, or atypical nose structures. Smoking might also raise your chances of getting a sinus
Reason for Sinusitis –
Sinusitis is caused by a virus, bacteria, or fungus that causes swelling and blockage of the sinuses.
Among the specific causes are:
 The typical cold.
 Mold allergies, as well as nasal and seasonal allergies
 Polyps (growths).
 A septum deviated. The septum is the cartilage line that divides your nose from your mouth. A
deviated septum is one that is not straight, leading it to be closer to the nasal passage on one
side of your nose, resulting in a blockage.
 A weakened immune system as a result of sickness or drugs.
 Exposure to smoke, either directly or indirectly through secondhand smoke
 A medical illness like cystic fibrosis or an immune system disorder like HIV/AIDS
To avoid sinusitis, you should avoid allergens such as dust, pollen, and smoke, as well as sick people.
To reduce the chances of getting a cold or flu, wash your hands.
