What is Asthma?
When we breathe through our nose or mouth, the air travels through the windpipe to the lungs and then to the airways which branch out in the lungs. In normal circumstances, the air ways remain open and unblocked resulting into unrestricted air flow. In case of Asthma flare up or Asthma attack, the airways become swollen or inflamed or produce excess of mucus which blocks the air flow. Since the person does not get enough air in and hence has to finds it difficult to breathe, feel tightness in the chest and will cough and wheeze.
An asthma attack may last from few minutes to few hours but once the attack is over, the airways come back to their normal shape though it takes time.
