Coughing is a natural reflex to clear the air passages of mucus, phlegm or potentially dangerous particles such as dust. A person with a chronic cough often takes it for granted. For example, many smokers accept their "smoker's cough" as a part of waking up in the morning. The problem may be more serious than they think.
Any cough that lasts a month or more is chronic. This is true even if it occurs only in the morning, only at night, or only in the winter. It is also true whether it is either a dry cough or a productive cough. A productive cough is one that brings up mucous. A productive cough that lasts for months or comes back year after year is often a sign of chronic bronchitis. Other serious lung infections include pneumonia and tuberculosis. Some common causes of chronic cough: - allergy
- asthma
- stomach acid (reflux)
- certain medicines
- anxiety
- infections
- smoking
However, a cough can also signal a chronic airway obstruction or even cancer. See a doctor if: - a cough lasts for more than three weeks
- you have sustained shortness of breath or severe pain or fainting
- you are coughing up blood
- you have trouble sleeping at night
- you have concerns about the cause of the cough or its cause is unexplained
Any cough that causes sustained shortness of breath, severe pain, or brings up blood should prompt seeking medical attention soon. Taking cough drops or syrups for more than a week may only mask an illness while it gets worse. Long-term use of cough syrups that are purchased without a prescription are usually not helpful and can be dangerous. Article #6416 Copyright (c) 2002 McKesson. All Rights Reserved. |
