A chronic cough is defined as one that lasts eight weeks or longer. More than simply an annoyance, a lingering cough can disrupt your sleep and affect your work. It may be accompanied by other symptoms such as wheezing, shortness of breath, runny nose, congestion and heartburn.<\/p>\n\n\n\n
If you have a persistent cough that doesn\u2019t disappear after a reasonable amount of time, make an appointment with your physician for an evaluation.<\/p>\n\n\n\n
What Causes Chronic Cough?<\/h2>\n\n\n\n
A cough is your body\u2019s way of expelling a substance that is irritating the air passages. When cells lining the air passages become irritated, they trigger air in the lungs to be forced out under high pressure.<\/p>\n\n\n\n
Chronic coughing can be triggered by a variety of factors. These include:<\/p>\n\n\n\n
Postnasal drip<\/li>
Asthma<\/li>
Allergies<\/li>
Gastroesophageal reflux disease (GERD)<\/li>
Upper respiratory tract infections<\/li>
Chronic obstructive pulmonary disease (includes bronchitis and emphysema)<\/li>
Pertussis (whooping cough)<\/li>
Air pollution<\/li>
ACE inhibitors (found in some medications used to treat high blood pressure and heart disease)<\/li><\/ul>\n\n\n\n
Smokers are most at risk for developing a chronic cough, as are those exposed to secondhand cigarette smoke.<\/p>\n\n\n\n
