Although sinus plays an important role in improving our sound quality, the main function of the sinuses is to produce mucus (sticky and thick liquid) in the nose to stop allergens, germs, and other substances that can cause infection and harm a person’s health.
With the help of cilia, which are as small as hair, mucus and substances caught by mucus will be pushed into the throat, past the abdomen, until it eventually dissolves on its own. This process is so subtle that one cannot feel it.
Factors which cause sinus infection symptoms
Sinus infection symptoms can be caused by the following factors:
- Congenital abnormalities – Blockage of the sinuses can be caused by bony deformities in the nasal cavity and septum (barrier between the two nasal cavities) are bent.
- Virus – The cold virus will affect the nasal passages, but because the sinuses are near the nose, it is possible that the virus will migrate and enter the sinuses. Sinusitis caused by a virus usually lasts longer than a cold. Viruses that cause flu can also cause sinusitis.
- Dental infection – Bacteria can be nested in many parts of the mouth, including teeth and gums. If not treated immediately, bacteria can cause inflammation, which can spread to the maxillary sinus.
- Allergic Rhinitis – Many people are mistaken between sinusitis and rhinitis because both are diseases characterized by very thick mucus. Rhinitis is an allergic reaction to pollen, animal dander, dust, etc., which causes nasal irritation. When the nose is irritated, the nose will be forced to produce more mucus. When mucus is pushed into the throat, the throat will also become irritated, and the patient will cough.
