What's causing your chronic cough? Rush experts begin by pinpointing the reason for persistent coughing, whether it's asthma, allergies, GERD or another issue.
Everybody coughs when the nerve endings in their airway get irritated. But a cough becomes chronic, or persistent, when it lasts eight weeks in an adult or four weeks in a child. Chronic cough gets in the way of everyday life and can make it hard to sleep or rest.
If your cough, or your child's, has gone on for weeks, it's time to get checked by your primary care doctor or pediatrician. If you or your child is having trouble breathing, call 911 or go to the nearest ER right away.
What Causes Chronic Cough?
Chronic cough isn't a disease by itself, but a symptom of something else. The most common causes include the following:
- Allergies and sinus infections
- Gastroesophageal reflux disease (GERD)
Other causes that are less common include the following:
- A cough that started with an illness and then became habitual
- Airway blockage or tumor
- Blood pressure medications known as ACE inhibitors
- Chronic obstructive pulmonary disease (COPD)
- Cystic fibrosis
- Swallowing problems (aspiration)
- Whooping cough (pertussis)
Your cough could have more than one cause, so it's important to see a physician who specializes in diagnosing and treating chronic cough and can give you a thorough assessment.
Diagnosing Chronic Cough
Diagnostic tests to find the cause of chronic cough might include the following:
- Bronchoscopy or endoscopy for a close-up look at your lungs or throat
- Imaging, such as an X-ray of your chest or a CT scan of your sinuses
- Lab tests to check for infection, including blood tests, sputum tests and nasal or throat swabs
- Lung function tests to see how well you're breathing
