The common causes of chronic dry coughing include [[post-nasal drip]], [[gastroesophageal reflux disease]], [[asthma]], [[post viral cough]] and certain [[drug]]s such as [[beta blockers]], [[ACE inhibitors]] and [[aspirin]]. If a cough lasts for more than three weeks, multiple causes are likely and symptoms will abate only when all the causes are treated will the patient be symptom free.  Individuals who [[Smoking|smoke]] often have a [[smoker's cough]], a loud, hacking cough which often results in the expiration of [[phlegm]].


Coughing may also be used for psychological or social reasons, such as the coughing before giving a speech.  This is known as psychogenic, habit or tic coughing, and may increase in frequency in social situations featuring conflict.<ref>{{citation | title = Coughing as an Indicator of Displacement Behaviour | url = http://www.collectionscanada.ca/obj/s4/f2/dsk2/ftp01/MQ33337.pdf | author = Arella, A. | year = nd }} (Unpublished thesis)</ref>
Given its irritant nature to mammal tissues, [[capsaicin]] is widely used to determine the cough threshold and as a tussive stimulant in clinical research of cough suppressants.

Complications

The complications of coughing can be classified as either acute or chronic. Acute complications include cough syncope (fainting spells due to decreased blood flow to the brain when coughs are prolonged and forceful), insomnia, cough-induced vomiting, rupture of blebs causing spontaneous pneumothorax, subconjunctival hemorrhage or "red eye", coughing defecation and in women with a prolapsed uterus, cough urination. Chronic complications are common and include abdominal or pelvic hernias, fatigue fractures of lower ribs and costochondritis.

Treatment

Coughs can be treated with cough medicines. Dry coughs are treated with cough suppressants (antitussives) that suppress the body's urge to cough, while productive coughs (coughs that produce phlegm) are treated with expectorants that loosen mucus from the respiratory tract. Centrally acting cough suppressants, such as codeine and dextromethorphan reduce the urge to cough by inhibiting the response of the sensory endings by depolarization of the vagus nerve. A recent study indicates that, because of the presence of theobromine in chocolate, 50 grams of dark chocolate may be an effective treatment for a persistent cough.[3]

Gargling with salt and warm water can also be helpful by reducing phlegm.

During injections

Coughing during an injection can lessen the pain of the needle stick caused by a sudden, temporary rise in pressure in the chest and spinal canal, inhibiting the pain-conducting structures of the spinal cord.[4]
