ABOUT Asthma

There are over five million people with asthma in the UK. That is one in every 12 adults. Although the respiratory system is essentially in good working order, the bronchi (small tubes carrying air in and out of the lungs) become inflamed and more sensitive than usual.

When you come into contact with something that irritates your lungs, your airways narrow, the muscles around them tighten and there is an increase in the production of sticky mucus (phlegm).
