Nasal polyps are soft, non-cancerous growths in the nasal cavity or sinuses. The cause of nasal polyps is not known, but there are a number of factors that may contribute to this type of disease. Any condition that causes chronic inflammation of the nasal cavity or sinuses may increase the risk of developing nasal polyps. Conditions commonly associated with nasal polyps include chronic sterile inflammation caused by asthma, recurrent infections and allergies, and may also be caused by some immune disorders. Nasal polyps are associated with infections and allergies caused by pathogens in the lining of the nasal cavity and sinuses and are present for more than 12 weeks. Normal sized nasal polyps do not cause any symptoms, but larger nasal polyps can block the patient’s nasal cavity and sinuses, which can cause complications because they block normal airflow and fluid drainage, facial pain or headache, pain in the upper teeth, and loss of taste due to polyps blocking odor particles into the olfactory area. To prevent nasal polyps in daily life you should pay attention to control the symptoms of asthma and allergies, avoid inhaling some substances that irritate the nasal cavity, pay attention to keep the living space moist and pay attention to hand washing. The triggering of nasal polyps is related to some chronic diseases and also to personal habits, so you should pay attention to avoid some triggering factors in daily life.
