What is a chronic cough?

Chronic cough persistently lasts at least for eight weeks, and often much longer. Chronic cough is really a burden and negatively impacts your daily life, with insomnia, and mental exhaustion.1  A chronic cough can result from many conditions such as allergies and postnasal drips.

Etiologies of Chronic Cough

Most common causes of chronic cough are as follows:

  • Upper Respiratory Viral Infections: Many viral diseases cause upper respiratory tract infections. These infections irritate the mucosal lining of respiratory tract initiating cough.
  • Asthma: In asthma, the patient’s immune system becomes hyperresponsive to external stimuli resulting in respiratory inflammation. As asthma is a chronic allergic disease, cough occurring in asthma can also become chronic.
  • Pneumonia: Several viral and bacterial infections cause pneumonia in the lungs. Persistent pneumonia is always associated with chronic cough.
  • Chronic Bronchitis: Bronchitis is also an inflammatory condition that can lead to severe coughing.
  • Upper Airway Cough Syndrome: A wide spectrum of illnesses encompass this disease which includes allergic rhinitis, and bacterial or viral sinusitis.
  • Gastroesophageal Reflux Disease: It is the most common cause of chronic cough, and forty percent of the patients suffer from chronic cough due to this. Retropulsion of the stomach or intestinal contents into the larynx initiates coughing.2

Clinical Treatments of Chronic Cough

As chronic cough is a symptom, its treatment depends upon the underlying cause. However, to prevent the chronic cough itself, there are certain therapies which are as follows:

  • Antihistamines: Histamine is a chemical that is released by our body cells called mast cells during inflammatory conditions. Antihistamines are prescribed to those patients who got a cough due to the inflammation of their throat.
  • Nasal Decongestants: Most persons have runny nose associated with cough. Thus, nasal decongestants are drugs that decrease secretions dripping out of the nose. Decongestant sprays are also available nowadays.
  • GERD treatment: As previously stated, forty percent of the patients having chronic cough have gastroesophageal reflux disease (GERD). Doctors treat GERD in order to treat cough.4

  • Saltwater gargles: Saltwater gargling is one of the most effective therapy in soothing a sore throat and preventing wet cough.
  • Dietary changes for GERD: If you have a chronic cough due to GERD, avoid eating acidic and spicy food, which triggers retropulsion of food.
