There are 5.2 million people in the UK alone currently receiving treatment for asthma, including 1.1 million children. Asthma is a common condition that affects the airways - the small tubes that carry air in and out of your lungs.

If you have asthma, your airways are sensitive and easily become swollen. When they are irritated these airways constrict and become narrower as the muscles around them tighten. There may be an increase in the production of sticky mucus or phlegm. This makes it harder for you to breathe and causes wheezing and coughing. Your chest may feel tight.

The good news is that many people with asthma live happy, healthy and uninterrupted lives. Your doctor can advise you on how to minimise your asthma symptoms and prescribe appropriate treatment.
