What is Asthma?

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

What is an Asthma Attack?

An asthma attack is when symptoms are worse than usual. They can come on suddenly and can be mild, moderate or severe.

What happens during an asthma attack?

• The muscles around your airways tighten up, narrowing the airway.
• Less air is able to flow through the airway.
• Inflammation of the airways increases, further narrowing the airway.
• More mucus is produced in the airways, undermining the flow of air even more.
