The non-stop secretion of mucus from the nasopharynx is mostly considered to be related to rhinitis, sinusitis and nasopharyngitis.
1. Rhinitis: Bacterial or viral infection of the mucous membrane of the nasal cavity and nasopharynx can lead to hypersecretion of the glands. After exposure to allergens such as dust and pollen, the glands may secrete large amounts of bright secretions. The secretion flows to the nasopharynx, because the secretion contains inflammatory substances at the same time stimulate the nasopharynx, can lead to the nasopharynx non-stop secretion of mucus.
2. Sinusitis: Mostly because the inflammation of neighboring organs spreads to the sinuses, or inflammation of the mucous membrane of the sinuses caused by the swelling of the nasal mucous membrane blocking the sinus openings in the case of rhinitis. Secretion from the sinus overflow, sieve sinus, pterygoid sinus, maxillary sinus, frontal sinus secretion can flow to the nasopharynx, coupled with inflammatory secretion stimulation of nasopharynx, can lead to nasopharyngeal secretion.
3. Nasopharyngitis: Simple nasopharyngitis can also have glandular hypersecretion.
The non-stop secretion of mucus from the nasopharynx may also include other causes, which need to be clarified under the guidance of a doctor.
