Initially, the patient may be given some cough medicines to control the frequent bouts of cough. However, to completely cure chronic dry cough, it is very essential to find the root cause of the problem. Only then, it would be possible for a patient to recover fully from having chronic cough. For instance, if the person has cough variant asthma, he/she would be treated in the way asthma patients are treated. Another example would be if a person has gastroesophageal reflux, he/she would be given medications for this and also would have to follow a strict diet as well as change in lifestyle, which includes avoiding foods containing high fats, alcohol, smoking, chocolate, etc.
Chronic dry cough would surely decrease, once its cause is understood. If a person is suffering from chronic dry cough for a long time, it is important to visit the health practitioner, before the underlying problem aggravates leading to grievous situations.
