There are various factors that can cause sinusitis, such as viral infections and bacterial infections. Most sinusitis can heal on its own within 1–2 weeks. However, there are several causes of sinusitis that need special attention.
The causes of sinusitis can be different for everyone. However, in general, sinusitis can be caused by infection and irritation. Both of these can cause the sinus wall to swell and swell, thus decreasing sinus function.
A healthy sinus produces mucus to moisturize the sinus and nasal cavities as well as catch dust and germs. The nasal cavity and sinus are connected by a small hole called the ostium. Through this ostium, the air that enters the nose is also circulated into the sinuses to be filtered.
Here are some things that can cause sinusitis:
1. Virus infection
Viral infections are the most common cause of sinusitis. Sinusitis caused by a viral infection usually begins when you have the flu or a cold. This viral infection can cause the sinus wall to swell, thus blocking the ostium which should be the place where mucus comes out. As a result, mucus accumulates in the sinus cavity.
2. Bacterial infections
Although rare, bacterial infections can also be a cause of sinusitis. Bacteria that enter the nose can cause excessive mucus production so that there is a accumulation of mucus that is difficult to remove in the sinuses. This condition will support the growth of germs in the sinuses and cause sinusitis.
3. Fungal infections
Fungal sinusitis usually occurs in people with a weakened immune system. If your immune system is weak, the fungus will grow easier, especially on moist parts of the body such as the sinuses, and cause inflammation.
Allergies to dust, pollen, mites, and animal fur can cause allergic rhinitis. This condition causes the swelling of the nasal wall to clog the ostium.
In addition, allergies can also increase mucus production. The combination of these two conditions causes excess mucus to accumulate in the sinuses. As a result, bacteria become easier to grow and sinusitis occurs.
5. Nasal polyps
Polyps can grow in the nose or sinuses. Wherever it is located, the polyp mass can cause obstruction of the ostium and prevent mucus from coming out of the sinuses. This accumulation of mucus can cause inflammation that eventually triggers sinusitis.
6. Air pollution
Pollutants in the air such as dust, cigarette smoke, air pollution, and stinging odors can cause irritation to the nasal passages. Inflammation and swelling caused by irritation can increase the risk of sinusitis, especially if the exposure to air pollution is long and heavy.
7. Dry air
Dry air can cause mucus to become thick. This will make the mucus more difficult to get out of the sinuses. It is this accumulation of mucus that can eventually cause sinusitis.
