In most instances a cough is a temporary complaint, usually connected to an upper respiratory infection, a cold or an allergic reaction, and it settles within a week. If you are coughing every day, the problem may be more than a simple irritation, and it can be a signal that something else is going on.
How an ongoing cough affects daily life
Even an intermittent, chronic cough can noticeably affect your quality of life.
In public
Repeated coughing draws attention. People often assume you are sick, even when the cough is not from an infection.
Sleep
A lingering cough can keep you from falling asleep or wake you through the night, leading to daytime exhaustion.
Eating
Coughing can make swallowing difficult, which makes meals less enjoyable and can even lead to weight loss over time.
How to tell a lingering cough from a cold
Timeframe is the main marker. A cough that lasts beyond six to eight weeks is considered chronic. Other symptoms may come with it:
Post-nasal drip
Acid reflux or heartburn
Ongoing throat inflammation
Unexplained weight loss
Night sweats
Blood-tinged mucus
Shortness of breath or wheezing
A hoarse voice
Occasional fever
Common causes
Finding the trigger guides you and your doctor toward the right care.
Allergies
If your cough follows the seasons or flares around pollen or pet dander, allergies are a likely cause.
Sinus problems
Sinusitis often causes post-nasal drip, which irritates the throat and prompts a persistent cough.
Acid reflux and GERD
Stomach contents rising into the esophagus irritate the throat. Controlling reflux often reduces the cough.
Lung conditions
Asthma, COPD and pulmonary fibrosis commonly cause persistent coughing.
Medication
Some drugs, particularly ACE inhibitors for blood pressure, list chronic cough as a side effect. Ask your prescribing doctor about alternatives.
Smoking
Smoking damages lung tissue and routinely causes a chronic cough. Quitting is critical for resolving it.
When to see an ENT
Schedule an evaluation if your cough lasts longer than six to eight weeks and doesn’t improve with over-the-counter medication, or promptly if you notice:
Coughing up blood
Difficulty breathing
Unexpected weight loss
An otolaryngologist can examine you and use targeted testing to find the cause, whether it’s allergies, sinus inflammation or something more serious, and set out the right treatment.
