Causes and Risk Factors

What can cause a cough?
A cough begins when an irritant stimulates nerves in your respiratory tract. The irritation may come from a plug of mucus in the airway, postnasal drip, exposure to a chemical irritant or from a number of other causes. Occasional cough is normal because coughing helps clear foreign substances and secretions from your lungs and prevents infection. But a cough that persists for long periods of time is usually the result of an underlying problem. Possible causes of cough include:

  • Allergies
  • Asthma
  • Blood pressure drugs
  • Bronchiectasis
  • Chronic bronchitis
  • Chronic obstructive pulmonary disease (COPD)
  • Gastroesophageal reflux disease (GERD)
  • Habit cough
  • Lung cancer
  • Medications
  • Psychogenic cough
  • Postnasal drip
  • Postinfectious cough
  • Respiratory tract infection

Almost everyone coughs sometime. And some people cough a lot, nearly all the time. So can you tell the difference between a normal cough and a cough that might be problematic? When is a cough acute and when is it chronic?
