Chronic Cough: When Your Cough Won't Quit
Published: Apr 07, 2024
A cough that lasts more than 8 weeks can be frustrating and disruptive. Understanding the causes and treatments of chronic cough is key to finding relief.
Common Culprits Behind Chronic Cough
The most frequent causes of chronic cough include asthma, postnasal drip, and acid reflux. Other possibilities are certain medications, lung conditions, or smoking. Identifying the underlying cause is crucial for effective treatment.
Diagnosing the Root of the Problem
Your doctor will likely start with a thorough history and physical exam. Tests may include chest X-rays, breathing tests, or allergy evaluations. Sometimes, a trial of medication is used to help pinpoint the cause.
Treatment Options to Quiet Your Cough
Treatment depends on the underlying cause. Inhaled steroids may help asthma-related cough. Antihistamines or decongestants can address postnasal drip. For reflux, lifestyle changes and acid-reducing medications are often effective. In some cases, cough suppressants provide relief.
When to Seek Medical Attention
While many causes of chronic cough are not serious, some red flags warrant prompt medical care. These include coughing up blood, unexplained weight loss, or difficulty breathing. Persistent cough in smokers should always be evaluated to rule out lung cancer.
