Chronic Cough

Chronic (persistent) Cough

Causes start from the nose or nasal region and extend to the lower respiratory tract.

Three reasons were identified in 92% of non-smoking patients with normal chest X-ray.

1) Upper airway syndrome (previously called cough syndrome due to postnasal drip) The secretion that washes the sinuses and nose flows from the nasal cavity towards the throat. This is perceived by some patients as severe and leads to coughing. This situation causes allergic rhinitis, vasomotor rhinitis, post-infectious rhinitis, bacterial sinusitis, fungal sinusitis accompanied by allergy, chemical vapors and dusts, occupational environment, pregnancy, frequent use of nasal drops for a long time, severe postnasal drip and persistent cough.

2) Asthma is characterized by airway tightness, shortness of breath, cough and wheezing.

3) Reflux (acid leakage from the stomach to the esophagus and throat) This acid escape triggers the cough reflex. Another reason is that the acid content from the stomach escapes into the trachea, triggering coughing.

Other important causes are smoking and blood pressure medications called ACE inhibitors. Cough complaints improve 2 weeks after quitting the blood pressure medication indicated 4 weeks after quitting smoking.

These three conditions are the most important causes of persistent persistent coughs. “If the patient’s chest X-ray is normal and does not smoke”

Other causes of persistent cough are:
– Bronchiectasis
– bronchitisoksuruk tedavisi
– bronchial cancer
– Aspiration
– Chronic obstructive pulmonary disease
– heart failure
– Foreign body
– Interstitial lung disease
– Neuromuscular diseases
– Pertussis
– Psychological cough
– Sarcoidosis
– Leakage between esophagus and trachea
– tuberculosis
– Zenker’s diverticulum (the formation of a pocket in the esophagus and the accumulation of food in this pocket then causes reflux and bad breath)

As a result, if the patient has a persistent cough, he applies to an ENT and chest diseases specialist, and the patient is evaluated with advanced examination methods, if necessary, after a detailed endoscopic examination.

Chronic (Persistent) Cough

Cough is a normal reflex in a healthy person. Persistence may be a sign of an important disease. The cause of acute cough is usually found and easy to treat. Coughs lasting more than 3 weeks are called chronic coughs and should be investigated further. In a significant part of coughs, the cause may be more than one. Causes start from the nose or nasal region and extend to the lower respiratory tract. The 3 most common causes in adults are postnasal drip, asthma and reflux disease.

A. Causes related to the respiratory tract

1. Infection (sinusitis, rhinitis, tonsillitis, tuberculosis, viral upper respiratory tract infection).
2. Asthma
3. Mechanical causes (foreign body in the nose and bronchi, earwax)
4. Environmental factors (cigarette smoke, dust, air pollution, etc.)

B. Inflammatory lung diseases

C. Lung tumors and cysts, laryngeal diseases and foreign bodies.

D. Psychological cough

E. Some heart and blood pressure medications

The cause of cough in children varies with age. Reflux, large vessel anomalies and asthma are the most common causes in the first 1.5 years of age. Up to the age of 6, adenoid, tonsillitis, asthma and sinusitis form the first 4 rows. Between the ages of 6 and 16, the three most important causes are asthma, psychological and sinusitis.
