Cough and postnasal dripMold poison symptoms

Post-nasal drip (PND), also known as upper airway cough syndrome (UACS), occurs when the nasal lining produces an excessive amount of mucus which accumulates in the back of the nose and the back of the throat.


Postnasal drip gives you the feeling that you always want to empty your throat.

 symptoms are as follow :

  • cough.
  •  The need to clear your throat frequently.
  •  “Tickling” in the throat or sore throat.
  •  Excess mucus in the throat.
  • Stuffy or runny nose.
  • Hoarseness or wheezing when breathing.
  • Unusual and uncomfortable sensations in the throat (like a feeling of something trapped in the throat, tickling or throat irritation).
  • bad breath.


Numerous conditions may cause post-nasal fall.  It may result from allergies such as allergy to mold, viral infections, including colds, and sinus infections. Less common causes include allergic reactions to certain medicines.

  • Some people are more likely to suffer from sinusitis caused by mold. When mold fungi find their way through the sinus cavity, the immune system responds by releasing a chemical known as eosinophils to fight off fungi. This substance causes sinusitis and fungal irritation as long as the fungi remain within the sinuses.

Additionally, since the fungus grows in damp and dark environments, it can be difficult to get rid of the infection because the sinus cavity is the ideal host environment

  • Rhinitis (inflammation of the lining of the inner part of the nose) is one of the most common causes of post-nasal drip.
  • Sinusitis usually causes postnasal drip, runny or stuffy nose, followed by facial pain or pressure, coughing, or loss of sense of smell.
  • One of the most common reasons for nasal drip is Seasonal allergies caused by plants that release pollen may result in postnasal drip, as the body produces excess mucus to try to remove pollen germs.

Other causes of postnasal drip include:

  • Irritant chemicals from fragrances, cleaning products, dust, or environmental fumes.
  • Smoking.
  • Medications, including contraceptives and blood pressure medications.
  • Chronic respiratory diseases, such as chronic obstructive pulmonary disease.
  • Deviated Septum.


Postnasal drip is treated with the treatment of the underlying cause.

Treatment includes :


  •  antihistamines like loratadine (Claritin, Alavert),  cetirizine (Zyrtec), and desloratadine (Clarinex),  Nasal steroids such as fluticasone propionate, and antibiotics that may eliminate bacterial infection may be prescribed to relieve symptoms.
  • saline nasal sprays or irrigation, such as a neti pot, to flush mucus, bacteria, allergens, and other irritating things off the sinuses.

Home remedies

  • Drink liquids, especially hot liquids like tea or soup: They hydrate the mucous membrane of the nose and release the mucus. The thinner the mucus, the easier it leaves the nasal cavities.
  • Salty water gargle: works to decompose mucus, and is also useful to soothe a sore throat.
  • Inhale warm steam: it can reduce symptoms by humidifying the nose and throat, which facilitates the passage of mucus.
  • Use a humidifier: A humidifier adds moisture to the air, which contributes to the reduction of mucus. It may be particularly soothing in winter when the indoor air is dry.
  • Control humidity levels, especially in damp areas, such as bathroom tiles, near sinks, damp basements, and areas around windows by frequently cleaning the bathroom, Addressing all plumbing problems and leaks, opening windows, etc.
