Intractable cough is a persistent cough that lasts for more than eight weeks and does not respond to conventional treatment. It can be a sign of an underlying medical condition, and it can significantly affect a person's quality of life. The causes of intractable cough can vary and may include:
- Upper airway cough syndrome (UACS): This is also known as postnasal drip syndrome and occurs when excessive mucus production from the nasal cavity drips down the back of the throat, causing irritation and cough.
- Asthma: Asthma can cause chronic coughing that is often worse at night or in the early morning.
- Gastroesophageal reflux disease (GERD): GERD can cause stomach acid to back up into the esophagus, causing irritation and cough.
- Chronic obstructive pulmonary disease (COPD): COPD can cause chronic bronchitis and emphysema, both of which can lead to a persistent cough.
- Lung cancer: A persistent cough can be a symptom of lung cancer, particularly in smokers.
- Idiopathic cough: This is a type of cough with no clear underlying cause.
Treatment for intractable cough depends on the underlying cause. Treatment options may include:
- Medications: Medications such as antihistamines, decongestants, proton pump inhibitors, and inhaled bronchodilators may be used to treat underlying conditions such as UACS, asthma, GERD, or COPD.
- Speech therapy: Speech therapy can be used to teach breathing techniques and reduce the frequency and severity of coughing episodes.
- Cough suppressants: Cough suppressants may be prescribed in cases where the cough is particularly severe and disruptive.
- Surgery: In rare cases, surgery may be recommended to treat the underlying cause of the cough, such as removing a tumor in the lung.
If you are experiencing an intractable cough, it is important to see a healthcare professional for a proper diagnosis and appropriate treatment.
