MOST COUGHS ORIGINATE IN THE RESPIRATORY TRACT, THAT IS THE LUNGS, NASAL PASSAGES, SINUSES, ALSO THE THROAT AND THE BRAIN.
The lungs are branched organs (like an upside down tree), with spongy bubbles at the end of the branches – called alveoli (in place of leaves). Air from outside fills the lungs when we breathe in, the body absorbs the oxygen and passes it into our bloodstream, and on exhalation the excess air is expelled. The airways are covered by a mucous layer and little hairs, called cilia. The cilia move back and forth to force the mucous and any foreign objects out, in the form of a cough, sneeze or runny nose.
CAUSES OF COUGH:
Post nasal drip, allergies, asthma, bronchitis, acid reflux, TB, certain types of medication, viral and bacterial lung and nasal infections, heart failure, and many more.
Treatment of cough depends on what is causing the cough, sometimes this is not as simple to assess and a doctor needs to be consulted.
DRY COUGH
This generally means a cough that is non-productive, that means there is no phlegm being coughed up. This can be caused by certain blood pressure medications, allergies, exposure to dust or smoke, certain types of infections like whooping cough and croup also cause a dry cough.
The most common treatment of dry cough is a cough suppressant, removing oneself from the cause of the cough – e.g. Medication, smoke. Treating the underlying infection, steam or humidifier
WET COUGH

Generally these more serious conditions should be treated by a doctor.
SCRATCHY ITCHY COUGH
