Sinusitis occurs when the mucous membrane surrounding the sinuses close to the nostrils becomes infected. This typically follows a cold or an allergic reaction that has worsened.
There are 4 types:
Symptoms last less than 4 weeks and get better with the right care.
This type of infection does not get better with treatment at first. Symptoms last 4 to 8 weeks.
Chronic infection happens with repeated or poorly treated acute infections. These symptoms last 8 weeks or longer.
If you have 3 or more episodes of acute sinusitis in a year, it’s called recurrent.
The sinuses are hollow spaces, or air-filled areas, located close to the nasal passage. They produce mucus. This liquid helps to remove bacteria and other debris from the air you inhale.
A sinus infection may occur following a cold. The cold inflames the nasal passages, potentially obstructing the sinuses and resulting in an infection. Additionally, allergies can lead to the swelling of nasal tissue, increased mucus production, and the development of sinusitis.
Other conditions that can lead to sinusitis include:
When the flow of mucus is interrupted, it can allow bacteria to multiply. This results in a sinus infection, also known as sinusitis. The usual culprits for sinusitis, including viruses and bacteria, are also responsible for influenza or specific types of pneumonia.
