Cough Treatmemt London

A cough is a reflex action to clear your airways of mucus, phlegm and irritants such as dust, smoke or a foreign body.

A cough can be caused by inflammation of your upper respiratory tract (throat and windpipe) due to a viral infection. Viral infections include the common cold, flu, laryngitis and bronchitis. These viral infections can also spread to the lower respiratory tract (bronchi) to cause a cough.

A cough is a symptom of many illnesses and conditions including:

  • asthma,
  • asthma,
  • bronchitis
  • common cold,
  • influenza (flu)
  • smoking, and
  • whooping cough (pertussis).


Rarely, a cough is a symptom of a more serious condition such as lung cancer, heart failure, a pulmonary embolism (clot on the lung), tuberculosis (TB) or pneumonia .

Coughs caused by the common cold or by flu usually clear up after a few days. However, a cough that's caused by a lung infection, such as bronchitis, may be present for several weeks after the infection has gone because the inflammation in the airways can take a while to clear. If you've had a cough for more than two weeks following a viral infection, seek medical advice from your GP.
