Chronic obstructive pulmonary disease (COPD) Archive

A persistent cough that lasts longer than a few weeks can be worrisome, but for nonsmokers, the most common causes include asthma, bronchitis, gastroesophageal reflux disease, and medication for high blood pressure.

Several health issues are associated with nighttime coughing. Some of the most common are postnasal drip, gastroesophageal reflux disease (GERD), medication side effects, and heart failure. When a new nighttime cough lasts more than a few weeks, it's important to go to a doctor to rule out dangerous causes, such as heart failure. The doctor can also determine if a drug side effect, postnasal drip, or GERD is causing the cough, and prescribe medications to treat the condition.
