Nasal congestion is the partial or complete blockage of nasal passages, leading to impaired nasal breathing, usually due to membranes lining the nose becoming swollen from inflammation of blood vessels.
In about 85% of cases, nasal congestion leads to mouth breathing rather than nasal breathing. According to Jason Turowski, MD of the Cleveland Clinic, "we are designed to breathe through our noses from birth—it's the way humans have evolved." This is referred to as "obligate nasal breathing."
Nasal congestion can interfere with hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea or upper airway resistance syndrome. In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia. The problem usually resolves after surgery to remove the adenoids and tonsils, however the problem often relapses later in life due to craniofacial alterations from chronic nasal congestion.
Allergies, like hay fever, allergic reaction to pollen or grass
Common cold, influenza or COVID-19
Rhinitis medicamentosa, a condition of rebound nasal congestion brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays)
Sinusitis or sinus infection
Narrow or collapsing nasal valve
Pregnancy may cause women to suffer from nasal congestion due to the increased amount of blood flowing through the body.
Nasal polyps
Gastroesophageal reflux disease (theorized to cause chronic rhinosinusitis- the "airway reflux paradigm")
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. 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.
Prevalence of kyphosis has been linked to nasal obstruction in a study.

Rhinitis medicamentosa (or RM) is a condition of rebound nasal congestion suspected to be brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) and certain oral medications (e.g., sympathomimetic amines and various 2-imidazolines) that constrict blood vessels in the lining of the nose, although evidence has been contradictory. The characteristic presentation of RM involves nasal congestion without rhinorrhea, postnasal drip, or sneezing following several days of decongestant use.
La maladie à coronavirus 2019, communément appelée la ou le Covid-19 (acronyme de l'anglais coronavirus disease 2019), est une maladie infectieuse émergente de type zoonose virale causée par la souche de coronavirus SARS-CoV-2. Les symptômes les plus fréquents sont la fièvre, la toux, la fatigue et la gêne respiratoire. Dans les formes les plus graves, l'apparition d'un syndrome de détresse respiratoire aiguë peut entraîner la mort, notamment chez les personnes plus fragiles du fait de leur âge ou en cas de comorbidités.
La polypose nasosinusienne (PNS) ou naso-sinusienne, plus simplement appelée polypose nasale, est une maladie affectant les sinus de la face. C'est une maladie inflammatoire chronique. Elle se traduit par une congestion des muqueuses nasales et sinusiennes : pour des raisons mal connues qui peuvent être liées à une allergie, la muqueuse des sinus s'épaissit par multiplication anormale de cellules (comme dans la maladie asthmatique), pouvant entraîner selon le stade évolutif une gêne respiratoire, voire une perte d'odorat (anosmie) si la fente olfactive est atteinte.

1 In nine anaesthetized pigs we have studied the influence of intranasal or intrabronchial pretreatment with TASP-V, a neuropeptide Y (NPY) Y-2 agonist formed by the attachment of NPY 21-36 to a template-assembled synthetic peptide (TASP), on the functiona ...
