Mold allergy

If an individual has mold allergy, the immune system is highly sensitive to the mold spores. When the individual ingests or inhales the mold spores, the immune system overly reacts and attacks the mold with the immunoglobulin E antibodies.  These IgE antibodies will cause the mast cells to generate histamine which is a chemical that protects the body from infection.

Postnasal drip-mold allergy

Postnasal drip is a usual indication of mold allergies since an allergic response to mold triggers nasal issues.

The histamine that is released in the soft tissues will instigate the blood vessels to dilate and increase the flow of blood. Take note that this action will trigger the manifestation of symptoms such as itchiness in the eyes, mouth and throat along with nasal congestion, sneezing, coughing and runny nose.

Postnasal drip

It is important to note that the histamine released in the sinus cavity will lead to inflammation and swelling. The swollen nasal cavity clogs up the ability to drain out mucus and breathe via the nostrils. Histamine can also cause the mucus membranes to produce more mucus which will block the sinuses with mucus. Since the mucus could not drain from the nostrils, it will drip down to the rear part of the throat which is known as postnasal drip. This can also cause bad breath, cough and a lump-like sensation in the throat.


It is best to manage mold allergies by eliminating all visible molds from both exterior and interior of the house using bleach and water solution. You can also utilize an air purifier in order to minimize the amount of airborne mold spores and avoid eating foods that contain mold such as dried fruits, cheeses and sauerkraut. There are over-the-counter medications commonly used in order to manage allergic rhinitis including decongestants, antihistamines and pain medications. A doctor must be consulted before using any medications.

Allergy shots

The allergy shots can help eliminate postnasal drip due to mold allergy. A doctor must be consulted if this treatment options is suitable. The allergy shots involve a small amount of the allergen that is injected into the body. As time passes by, the doctor will increase the amount of the allergen being injected which will steadily desensitize the immune system to the hypersensitivity.
