Coughing is a natural solution the body prevents contamination, bacteria and allergens from entering the body, based on the Austin Diagnostic Clinic. When an allergen is breathed in, the body will respond by coughing to push it out of the throat. In other cases, an allergic reaction can cause the sinuses to develop mucus that drips down the back of the throat, leading to a cough. An allergy cough has common symptoms of a cough associated with other symptoms that are caused by an allergic reaction. Meet a family medical doctor or an allergist for a proper diagnosis.
Coughing is the most common symptom of an allergy cough, most likely a result of allergic rhinitis, according to the American Academy of Allergy, Asthma and Immunology. When the throat becomes irritated or tickled by an allergen or nasal discharge, the cough reflex responds by sending signals to the brain to get started coughing. Although coughing is beneficial to loosen and expel mucus buildup, it can also irritate the throat, increasing the cause of the cough, according to the Austin Diagnostic Clinic.
Post Nasal Drip
Postnasal drip is a usual symptom of an allergy cough. Postnasal drip is caused by inflamed sinuses. During an allergic reaction, the sinus cavity becomes irritated, cutting off the normal flow of mucus out of the nose. The stopped-up mucus slowly drains in the throat. The constant flow of mucus down the throat creates irritation and a tickling that creates a cough. Postnasal drip is handled by addressing the causes of the drainage. With an allergic reaction, the person prevents allergens and takes a daily antihistamine.
According to the Asthma and Allergy Foundation of America, if coughing is caused by allergic asthma, the cough will be associated with wheezing. This condition causes the air passages in the lungs to become inflamed, restricting breathing and causing a high-pitched sound, called wheezing. Wheezing may grow from further throat irritation. Wheezing is typically dealt with by avoiding allergens and using medicated inhalers that lessen inflammation in the airways.
Cough symptoms of an allergic reaction will be followed by other allergy symptoms, such as sneezing, watery eyes, asthma or nasal congestion. Sometimes hives and skin rashes may accompany an allergy cough. If you experiences shortness of breathe and cannot breathe, you should seek medical help immediately.
