What is Asthma?

March 26, 2010


ASTHMA is a disease affecting the airways that carry air to and from your lungs. People who suffer from this chronic condition (long-lasting or recurrent) are said to be asthmatic.

The inside walls of an asthmatic’s airways are swollen or inflamed. This swelling or inflammation makes the airways extremely sensitive to irritations and increases your susceptibility to an allergic reaction.

As inflammation causes the airways to become narrower, less air can pass through them, both to and from the lungs.

Symptoms of the narrowing include

  • wheezing (a hissing sound while breathing),
  • chest tightness
  • breathing problems
  • coughing.

Asthmatics patient usually experience these symptoms most frequently during the night and the early morning.

Several causes of asthma are :

  • Allergic
  • Tobacco
  • Environment factor as household cleaner and paints.
  • Obesity
  • Pregnancy
  • Atopy
  • Airway hypersensitivity
  • Genes
  • Stress
