Persistent Dry Cough


There is no doubt that a non-productive cough, better known as a dry cough, can be infuriating and frustrating. A dry cough is a throat condition that is accompanied by feelings of dryness, itchiness, or scratchiness in the throat. This results in irritation that often leads to swelling, and usually causes a reaction of coughing, choking and gagging.

Most coughs are considered acute, because they only last up to 3-4 weeks, before a recovery is made. It is when a cough lasts longer than this time period that it is considered to be a persistent dry cough. Whereas a cough usually lingers on after an illness and then improves, a long-lasting cough such as this should be taken as your body trying to wave a red flag at you.

If your cough lasts for a long time, then there is a reason why it isn’t healing. What this means, is that there is some underlying cause of the dry cough, which may or may not be medically serious. It is important to think of a persistent cough not as a disease in its own right, but as a symptom of another condition.

There are a whole host of potential causes for a persistent dry cough:

  • Lung disease
  • Allergies
  • Smoking cigarettes
  • Non-infectious disease
  • Lung tumour
  • Blood pressure lowering medication
  • Infectious disease
  • Air pollution
  • Asthma
  • Acid reflux
  • Many more…

You can see from the list above that the long-term health implications of the potential causes of a persistent cough very massively, but it is highly recommended to seek professional medical attention. A doctor will be far more accurate in diagnosing the cause of the cough, and trying to treat a cough without knowing the cause is like trying to get a hole-in-one with your eyes shut.
