Anyone who has struggled with postnasal drip will recognize the aggravating signs of frequent swallowing, needing to clear the throat, even a persistent cough. At Chacko Allergy, Asthma and Sinus Center in Atlanta, we use precise allergy testing to identify the underlying cause of this uncomfortable condition. Going beyond just temporary relief, this approach ensures you’ll get lasting results. But how do allergies contribute to postnasal drip, and what’s the best treatment approach?
What Is Postnasal Drip?
Postnasal drip is a condition where excess mucus accumulates in the back of the nose or throat. This buildup causes the sensation of a constant trickle of mucus down the throat. Along with symptoms of a sore throat and cough, people with postnasal drip may also experience sleep quality issues (unfortunately, lying down can often make the condition worse).
How Do Allergies Cause Postnasal Drip?
For many people, exposure to pollen, mold, dust and pet dander causes their immune system to respond, and a series of allergy symptoms will then appear. This can include watery eyes, itching and skin rashes – and of course, postnasal drip is often involved. To further understand how this works, read on.
Immune System Response
Following exposure to an allergen, the immune system mistakenly perceives a threat. In response, the immune system moves to protect the body, releasing antibodies called immunoglobulin E (IgE). These antibodies attach to various cells in the skin, respiratory system and other areas of the body.
Release of Histamine
After further exposure to the allergen, these immune cells release a chemical (histamine) that produces an allergic reaction. Histamine causes an itchy throat, swelling, congestion, hives and other symptoms.
Nasal Inflammation
One of the main effects of histamine release is inflammation of the nasal passages and an increase in mucus production. These changes occur as the body tries to trap and remove allergens from the nasal passages and sinuses.
Mucus Builds Up
With an excess of mucus in the nose and throat, individuals experience the sensation of postnasal drip. Frequent exposure to the allergen (such as pollen during allergy season) means this feeling of mucus trickling down the throat will persist without treatment.
Allergy Treatments to Prevent Postnasal Drip
Simple treatments like saline solution, nasal sprays and antihistamines can offer some relief for isolated cases of postnasal drip. However, when this condition is recurring in nature, you’re likely to need a long-lasting treatment for nasal allergies. Your allergist may recommend allergy shots as an effective way to desensitize the immune system to allergens, ensuring that the body does not react after contact with pollen, dust, mold and other substances.
