Chronic cough is a persistent cough

A chronic cough is a persistent cough that lasts for eight weeks or longer in adults, or four weeks or longer in children. It is a common symptom of various underlying conditions and can significantly impact a person’s quality of life. Identifying the cause of the cough is crucial for appropriate management and treatment.

Causes of Chronic Cough

  • Upper Airway Cough Syndrome (UACS): UACS, previously known as postnasal drip syndrome, occurs when excessive mucus production or irritation in the nasal passages and sinuses triggers a cough reflex.
  • Asthma: Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways. Coughing is a common symptom, especially during asthma attacks or when triggered by specific allergens or irritants.
  • Gastroesophageal Reflux Disease (GERD): GERD is a condition in which stomach acid flows back into the esophagus, causing irritation and triggering a chronic cough. It is often worse at night or after meals.
  • Chronic Bronchitis: Chronic bronchitis, a form of chronic obstructive pulmonary disease (COPD), involves persistent inflammation of the bronchial tubes. A chronic cough with phlegm production is a key symptom.
  • Medications: Certain medications, such as angiotensin-converting enzyme (ACE) inhibitors used for high blood pressure, can cause a persistent cough as a side effect.
  • Respiratory Infections: Chronic cough can result from recurrent respiratory infections, such as bronchitis, pneumonia, or pertussis (whooping cough). You can buy cough medicines or other medications like alp tablet online through oladoc.
  • Interstitial Lung Disease (ILD): ILD refers to a group of lung disorders characterized by inflammation and scarring of lung tissue. Chronic cough can be a symptom of ILD.
  • Lung Cancer: A persistent cough can be an early symptom of lung cancer. It is essential to consider this possibility, particularly in individuals with risk factors like smoking or exposure to environmental carcinogens.

Evaluation and Treatment

  • Medical History and Physical Examination: The healthcare provider will assess the duration and characteristics of the cough, as well as any associated symptoms or triggers. A physical examination may help identify clues to the underlying cause.
  • Diagnostic Tests: Additional tests may include spirometry, chest X-ray or CT scan, allergy testing, sputum analysis, or bronchoscopy to evaluate the airways and rule out specific conditions.


The treatment of chronic cough depends on the underlying cause:

  • Asthma: Inhalers and other asthma medications can help manage symptoms and control coughing.
  • GERD: Lifestyle modifications, such as dietary changes and elevating the head while sleeping, along with medications to reduce stomach acid, are often recommended.
  • Chronic Bronchitis: Bronchodilators, inhaled steroids, and pulmonary rehabilitation may be prescribed to manage symptoms and improve lung function.
  • Medication-induced Cough: Switching medications or adjusting the dosage may alleviate the cough.
  • Other Causes: Treatment will depend on the specific underlying condition identified through diagnostic tests.

Cough Management

Regardless of the cause, certain measures can help alleviate cough symptoms, such as staying hydrated, avoiding irritants like smoke or strong odors, using cough lozenges or honey, and employing proper cough etiquette. Your doctor may also prescribe certain cough syrups like acefyl syrup to ease your symptoms.


A chronic cough is a persistent cough lasting eight weeks or longer in adults, or four weeks or longer in children. It can result from various underlying conditions, including UACS, asthma, GERD, chronic bronchitis, or medications, etc.
