A<unk>  is a sudden, often repetitive, spasmodic contraction of the thoracic cavity, resulting in a violent release of air from the lungs, and usually accompanied by a distinctive sound. A<unk>  by itself is not a complete diagnosis but rather a symptom of an underlying condition, despite this, it accounts for one of the most common indications for visits to the general practitioners and family physicians with a good proportion of these cases resulting in a pulmonology referral.<unk> ing is an action the body takes to get rid of substances that are irritating the air passages. The act of<unk> ing can be triggered by a myriad of conditions physiologic and otherwise, A<unk>  is mostly initiated to clear a buildup of phlegm within the trachea.<unk> ing can also be triggered by a bolus of food entering the trachea and other parts of the respiratory tree rather than the esophagus due to a failure of the epiglottis. During the management of<unk>  the duration is an important tool utilized by the clinicians; and when presented with a history of frequent or chronic<unk> ing the presence of an underlying disease should be suspected. In non-smoking patients with a normal chest X-ray, chronic<unk>  in 93% of these patients' cohort can be attributed to  asthma, heartburn or post-nasal drip. Other causes of chronic<unk>  include chronic bronchitis and medications such as ACE inhibitors.<unk> ing can happen voluntarily as well as involuntarily.
The uncleanness of most cases of<unk>  with regard to etiology, duration, and other precipitating symptoms coupled with the lack of a universal guideline for quantifying<unk>  results in variability during its assessment. Thus, a thorough evaluation should be done to isolate the etiology of the patient's<unk>  when they present, and before initiating therapy for symptomatic relief.
