Recurrent sinus infections (chronic sinusitis) are defined by the Mayo Clinic as a sinus infection lasting for more than eight weeks or continue to come back over a period of time. Sinus infections are an infection in the sinus cavity resulting from either a bacteria or virus. Reoccurring sinusitis is commonly the result of nasal polyps, a deviated septum, severe allergies or another medical condition.
Nasal Polyps
Nasal polyps are small growths in the nasal cavity. Nasal polyps can develop in anyone; however, adults suffering from allergies or asthma present a greater risk of developing nasal polyps. The cause of nasal polyps remains unknown but is treatable with prescribed steroid nasal sprays or surgery. Nasal polyps create an obstruction in the nasal passages which can lead to improper drainage and difficulty breathing. The blocked mucus creates a moist and warm environment where infection thrives.
Deviated Septum
A deviated septum also blocks the normal drainage through the nose, promoting reoccurring sinusitis. A deviated septum is a physical condition where the center wall of the nasal cavity becomes crooked, according to the Mayo Clinic. This condition can either result from a physical development or a facial injury. A deviated septum can range from minor to severe, blocking a portion of breathing through the nostrils or complete obstruction. Surgery remains the only option to treat this condition.
Severe Allergies
A person suffering from severe allergies may experience reoccurring sinus infections. One of the most common symptoms of an allergic reaction is nasal congestion and drainage. In order to help reduce the risk of developing reoccurring sinus infections, a person with allergies can take an over-the-counter (OTC) antihistamine such as Loratadine coupled with a decongestant such as Pseudoephedrine, during highly allergic seasons, according to the American Academy of Otolaryology. The antihistamine will help to maintain proper histamine levels in the body, reducing allergic symptoms. The decongestant will help reduce swelling in the sinus cavity, providing proper drainage. See a doctor if OTC medications do not help your allergy symptoms.
Other Medical Conditions
Some medical conditions such as HIV or cystic fibrosis can create blockage in the nasal cavity, resulting in recurrent sinus infections, according to the Mayo Clinic. HIV weakens the immune system, making a person more prone to infection in the body. A respiratory tract infection, typically caused by the common cold, can also produce recurrent sinusitis.
