What is asthma?

Asthma is a common long-term condition that affects your lungs. It makes your airways (the tubes that carry air in and out of your lungs) more sensitive. 

When these airways are irritated by certain triggers, they become inflamed and narrow. This can cause the following symptoms: 

• Wheezing 
• Shortness of breath 
• Coughing 
• A tight feeling in your chest

Asthma symptoms can sometimes get worse suddenly, even without a clear reason.

Common triggers include

•  Pollen, dust, and animal fur 
• Smoke and pollution 
• Chest infections or colds 
• Exercise 
• Changes in the weather 
• Substances at work (like fumes or dust) 

There is no cure for asthma, but with the right treatment, most people live normal, active lives.

How is asthma treated?

Most asthma is treated with inhalers, and sometimes tablets. There are two main types of inhalers: 

1. Reliever inhalers. Used when symptoms appear. They quickly relax the airways to make breathing easier. 
2. Preventer inhalers. These are used every day, even when you feel well. They help stop symptoms from starting by reducing inflammation in your airways. 

Your doctor might also prescribe steroids to help reduce swelling in your airways. 

If your symptoms do not improve, or your diagnosis is uncertain, you may be referred to a lung specialist. 

How to manage asthma at home

1. Monitor your asthma. You may be given a peak flow meter. This is a small device to measure how fast you can blow air out of your lungs. Keeping a diary of your readings can help track your progress.  Your GP practice may also have an asthma nurse who can help you manage your treatment. 

2. Stop smoking. Smoking or breathing in other people’s smoke makes asthma worse. Your GP or nurse can support you to stop. You can also contact a local Stop Smoking Service via www.nhs.uk. 

3. Use your inhaler properly. Using your inhaler with the correct technique is important so the medicine reaches your lungs. We will check your technique before you leave hospital, but your practice nurse can also help. 

If you find inhalers hard to use, you might be given a spacer, which is a plastic tube that makes inhalers easier and more effective. 

4. Avoid your triggers. Your doctor or asthma nurse can help you identify things that make your asthma worse and work with you to avoid them. 

5. Use your asthma action plan. You should have a written asthma action plan from your doctor. It explains: 

• How to stay well
• What to do if symptoms worsen
• How to manage an asthma attack 

Keep it handy and refer to it often.
