There are many conditions that affect the lungs and airways, from simple coughs and colds to more complex, life-long conditions like asthma and cystic fibrosis. This section has information on all of them. If you want to know “Are my symptoms just a cold, or is it more serious?” or “How do I look after my asthma?” you will find helpful information here in our doctor-authored leaflets. We will answer questions about usual investigations such as “What is spirometry?” and also treatments, like “Which inhalers do I need for COPD?”.
