Can mold allergy cause constant postnasal drip?

The constant drip of mucus at the rear part of the throat can become an annoyance if it progresses into a chronic. Always bear in mind that postnasal drip is a typical indication of mold allergy since an allergic response to mold triggers the manifestation of nasal problems.

Chronic postnasal drip due to mold allergy is properly managed by eliminating exposure to mold. It is recommended to schedule an appointment with an allergist in order to determine if immunotherapy is required.

Postnasal drip
Since the mucus could not drain from the nostrils, it drips down the rear part of the throat which is considered as postnasal drip. Once this occurs, it can cause coughing, bad breath and a feeling of a lump in the throat.

If an individual is allergic to mold, the immune system responds erratically if mold spores are present in the environment. Once the individual inhales or ingests mold, the immune system triggers an attack with immunoglobulin E antibodies (IgE). These antibodies cause the mast cells to produce histamine which is a chemical that protects the body against infection. The histamine released in the soft tissues causes the blood vessels to dilate and increase the flow of blood. Take note that this action causes itchiness in the eyes, mouth and throat along with nasal congestion, sneezing, coughing and runny nose.

Why does postnasal drip occur?

The histamine that was released in the sinus cavity causes inflammation and swelling. The inflamed nasal cavity obstructs the drainage of mucus and capability of the individual to breathe via the nostrils. Histamine can also cause the mucous membranes to produce more mucus that can clog the sinuses.

Management

Mold allergy can be managed by removing all visible molds from both interior and exterior of the house using bleach and water solution. You can utilize an air purifier inside the house to minimize the amount of airborne mold spores. In addition, the individual should avoid eating foods that contain mold such as dried fruits, cheeses and sauerkraut.

There are over-the-counter medications typically used in managing allergic rhinitis which includes decongestant, antihistamines and pain medications. A doctor should be consulted before using any medication to be safe.

What are allergy shots?

Allergy shots can be used to help eliminate postnasal drip due to mold allergy. It is important to note that allergy shots utilize a small amount of the allergen and injected into the body. After some time, the allergist will increase the amount of allergen injected which steadily desensitizes the immune system to hypersensitivity.

The best way to avoid postnasal drip due to mold allergy is to eliminate any mold in the house and outdoors. If possible, hiring professional services is recommended so that proper measures are taken in order to effectively eliminate mold inside and outside the house.
