Causes of Frequent Sinus Infections
Frequent sinus infections (sinusitis) can be both painful and annoying. Sinuses are small cavities found inside the skull and face. When sinuses become inflamed or clogged, sinus infections can happen. People who suffer from colds on a regular basis may be more prone to frequent sinus infections. Sinus infections need to be diagnosed by a medical doctor and are treated with antibiotics.

Nasal Polyps
-
A common cause for frequent sinus infections is nasal polyps. Nasal polyps are small bumps that grow inside the sinus cavitities and cause pain and pressure.
Chronic Allergies
-
Chronic allergy sufferers are also at risk for frequent sinus infections. Allergens become clogged in the sinuses, which causes inflammation, headaches and facial pain.
-
Viruses
-
People who suffer from colds or flus on a regular basis are more prone to sinus infections. When viruses attack nasal passages and sinuses, the hollow spaces become blocked with mucous, and bacteria multiplies quickly inside the sinuses. (Sinus infections are caused by this bacteria.)
Environmental Conditions
-
Heat, cold, dry air, altitude change, heavy smoke or perfume scents can also cause frequent sinus infections. When people are exposed to harsh elements on a regular basis, they are more prone to chronic rhinitis (inflammation of the nasal passages), which often leads to sinus infections.
Weakened Immune Systems
-
People who suffer from weakened immune systems, such as cystic fibrosis or HIV patients, are at risk for developing chronic sinus infections. Because they cannot fight off bacterial or viral infections efficiently, these people may experience more sinus infections than people with healthy immune systems.
