Sinus Infection Causes
The sinus cavities are the air-filled spaces in the face that are located around the nose and eyes. They play an important role in both your respiratory and immune systems. They help you breathe by regulating humidity and keep you safe by filtering substances like dust and germs.
The sinus cavities help to keep you from getting sick by trapping substances in mucus and then draining them out of the body. Sometimes, when the body traps substances like bacteria, viruses, or fungi in the mucus it can react with swelling. When these substances cause the sinus cavities to swell the mucus cannot drain normally and this is when an infection can develop. Other conditions like a deviated septum, nasal polyps, or allergies can also make it hard for mucus to drain and lead to more frequent infections.
When left untreated, sinus infections have the potential to turn into a more serious issue. If you suffer from any of the following symptoms, you should schedule an appointment to be evaluated for sinusitis.
