Chronic Cough Lasting More Than 3 Weeks: When to Consult a Pulmonologist

Why Cough Syrups Fail in Chronic Cough

Most over-the-counter cough syrups contain sedatives or decongestants that merely suppress the cough reflex in the brainstem without addressing the underlying root cause in the lungs or throat.

If your cough has persisted for more than 3 weeks, relying on repeated rounds of antibiotics and syrups can delay the diagnosis of treatable respiratory conditions.

Top 4 Underlying Causes of Unexplained Chronic Cough

• Cough Variant Asthma: Asthma presenting solely as a dry, non-productive nocturnal cough without obvious wheezing.
• Upper Airway Cough Syndrome (UACS): Chronic sinus drainage dripping into the hypopharynx, irritating the vocal cords.
• Gastroesophageal Reflux (GERD): Micro-aspiration of stomach acid irritating the laryngeal nerves, worse when lying down flat.
• Endobronchial Infections or Lesions: Unresolved endobronchial tuberculosis, fungal plugs, or airway lesions accurately diagnosed via Video Bronchoscopy.
