Asthma

What is Asthma?

Asthma is a long-term condition that affects the lungs. Often starting in childhood, asthma causes swelling and narrowing of small tubes that carry air in and out of the lungs, causing coughing and shortness of breath.

Asthma is very common, affecting 2 out of every 10 people in Scotland. Over 5 million people in the UK require treatment for asthma.

There is no cure for asthma and the cause is not always clear. However, your symptoms can be controlled with treatment and avoiding triggers that can make it worse.

Common symptoms of asthma

If you have asthma, you may experience one of more of these symptoms:

  • Shortness of breath
  • Coughing
  • Wheezing
  • Chest tightness

These symptoms usually come and go and can change throughout the day. They can happen at rest or when performing activities and they are sometimes worse at night. If you are experiencing these symptoms, make an appointment to see your doctor.

Asthma is a very manageable condition. It is usually treated with both reliever and preventor inhalers, though some people are also prescribed tablets.

Asthma treatment

The most common treatment for asthma is inhalers:

  • Reliever inhaler – these are reactive inhalers that are used when symptoms occur and will relieve symptoms within five minutes. If you need to use this more than three times a week, speak to your doctor.
  • Preventor inhaler – these are used daily to reduce inflammation and sensitivity of airways. Preventor inhalers contain steroid medicine and if you are using your reliever inhaler too often, you’ll be prescribed a preventor inhaler.
  • Combination inhaler – these are prescribed when asthma isn’t fully controlled by a reliever inhaler or a preventor inhaler. These are used daily and provide long-lasting relief. It’s essential to use this daily to improve your asthma when you have been prescribed this kind of inhaler.

Other treatments include tablets, injections and, in rare cases, surgery. If you’re diagnosed with asthma, your doctor will discuss potential treatments for you.

Living well with an asthma diagnosis

Once diagnosed and treated, most people feel much better, but you may be looking for other ways to support your treatment. Make sure that you use your prescription as directed, eat healthily and stay hydrated.

Exercise can sometimes be a little difficult for asthma sufferers. Your doctor will advise you on suitable exercise for you.
