Allergic rhinitis is triggered by the body’s reaction to an environmental stimulus such as dust, molds, pollens, grasses, trees, or animal dander.There are two broad classifications of rhinitis, allergic and non-allergic, but symptoms and causes often overlap, making diagnosis challenging. Rhinitis is caused by inflammation, irritation, and swelling of nasal mucosa and, in addition to causing chronic coughing, manifests as a runny nose and nasal stuffiness. The good thing is that treatment with medication that suppresses acid secretion in the stomach usually resolves symptoms fairly quickly. While classic reflux is generally associated with symptoms such as heartburn and regurgitation, non-classic reflux symptoms can also occur and include a sensation of food sticking in throat, hoarseness, chronic cough, and wheezing. Some studies have found that coughing in and of itself can lead to reflux, which then leads to chronic coughing. These two theories are not mutually exclusive. Due to close proximity, there is a nerve-mediated reflex of stomach acid into the esophagus that triggers bronchospasm and airway inflammation resulting in a cough. Reflex theory originates from the embryonic stage of development of the digestive and respiratory tracts. Reflux theory is based on the notion that the cough is protective: Small droplets of acid or food particles from the stomach are aspirated into the larynx and/or upper airway, provoking cough as a defensive mechanism to expel the droplets and protect the airway against caustic injury. Two common theories of how the disease causes chronic cough are the reflux theory and the reflex theory. population develops GERD, and it is often the source of chronic cough. Gastroesophageal reflux (GERD)Ībout 20 percent of the U.S. Treatment for cough-variant asthma typically includes the same medications used for traditional asthma, and symptoms generally improve over the course of six to eight weeks.
