Causes and Remedies for Persistent Dry Cough

Home Remedies

A dry cough, also known as persistent dry cough, and productive cough are of two types. A productive cough is usually experienced with phlegm or mucous-whilst coughing and should not be suppressed. Phlegm is the gunk that the body needs to get rid of. Persistent dry cough, on the other hand, usually occurs together with a tickly cough and is usually caused due to allergy or by viral infections. Unlike a productive cough, a dry cough does not produce any phlegm or mucous.

Since persistent dry cough is caused by viral infection, it is important to understand the underlying problem before discussing the remedies of the same. A dry cough can be triggered by cold, flu viruses and other atmospheric pollutants that irritate the throat. Dry coughs usually result due to irritation or inflammation at the back of the throat. Also, it can sometimes arise deeper in the chest.

Persistent dry cough not only irritates but also disturbs sleep pattern. Let’s understand the common problems that cause persistent dry cough.

Following are the common causes of dry coughs:

Viral infections –Commonly known as cold and flu, viral infection causes coughs that occurs at the start or middle of an illness and lingers on even when other symptoms of the infection have subsided.

Allergies –Allergies are also seen to be behind dry coughs. For instance, Hayfever, an allergy to tree pollen and grass, leads to eyes and nose irritation and is often seen to lead to coughs. People who are sensitive to other particles like animal fur, which is termed as allergic rhinitis, are at risk of developing this symptom.

Air pollutants –It is often seen that air pollutants often irritate the back of the throat. This can give rise to dry coughs. A simple example of this would be a non-smoker entering a smoking room. The pollutants resulting from the smoke can irritate and cause the person to cough continuously.

Acid reflux – Acidic contents present in the stomach moves upwards to the back of the throat, and some can make their way in the respiratory tract. This causes inflammation in the back of the throat resulting in constant coughing. Acid reflux is a noticeable element of GERD (Gastro-oesophageal Reflux Disease).

Other Causes

Medication – some medicines, like those prescribed to control high blood pressure, have their side-effects and can result in a dry cough.

Psychological conditions – Referred to as psychogenic cough, there is no bodily illness behind a cough. In this case, coughing is more of a habit and goes away when the person is asleep.

Stress – Stress has seen to have a direct impact on coughing. In a stressful situation, anxiety is seen to slower the breathing process thus triggering the cough reflex.

Asthma – A recurring disease, asthma causes the airways to become inflamed, and these get partially blocked.

Heart disease – Heart problems lead to building up of fluids in the lungs that can cause heart failure. People suffering from persistent dry cough should get it immediately checked.

Lung problems and cancer – Persistent dry cough points to lung problems, including lung cancer
A whooping cough – Bordetella pertussis is a known cause of this bacterial disease which is characterized by stints of coughing which leaves the person gasping for air.

Tuberculosis –Predominantly affecting lungs, TB is a highly infectious bacterial disease which gives rise to dry a cough.
