Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
It has been shown that the cilia of the congested side suspend their motility until that side decongests. Thus the cycle ensures that one side of the nose is always moist, to facilitate humidification, which is one of the three functions of the nose, the other two being filtration and warming of inspired air prior to its entering the lungs.

Choanal atresia is a congenital disorder where the back of the nasal passage is blocked, usually by abnormal bony or soft tissue (membranous) due to failed hole development of the nasal fossae during prenatal development.
Coughing is a physiologic way to rid one of some of the congestion, says Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security. Controlled cough is a mucus-clearing ...
Upper airway: Obstruction of the upper airway is common in infants less than 3 months old because they are nose breathers. Nasal blockage may easily lead to upper airway obstruction in infants. For other ages, upper airway obstruction may occur from a foreign body or edema of the pharynx, larynx, or trachea.
One symptom is a same-side nose blockage (unilateral nasal obstruction). [3] When an OAC or OAF is present, the passage to the maxillary sinus can results in infection and inflammation. [citation needed] This subsequently results in mucus build up presenting as a unilateral nasal blockage. Sinusitis may also be present as a pain in the middle ...
The sneezing, coughing and runny nose are enough to drive anyone crazy. But having a blocked nose, whether it's from an illness or just plain ol' seasonal allergies is perhaps the worst symptom of ...
The baby formula shortage began in February 2022 after Abbott Nutrition, a major U.S. formula producer, shut down its largest plant and issued several formula recalls following bacterial ...
