Information About Asthma

More than 5 million people in the UK suffer from asthma and it seems to be on the increase. This is partly because methods of diagnosis are more refined but there is also concern that it may be associated with the problem of pollution.

Here is some brief information on asthma. More information is available from your pharmacist and doctor or click on our link sites.

What is Asthma?
Asthma is a problem affecting the small tubes that carry air in and out of your lungs. These tubes or “airways” are sensitive and can easily become swollen and inflamed. Various irritants can cause them to narrow and fill with sticky mucus or phlegm. This makes it difficult for you to get enough air and causes wheezing, coughing and a tight feeling in your chest.
The natural course of asthma differs from person to person and varies from day to day. It is often worse during the night and during or after exercise.

What is the cause of asthma?
Asthma is an allergic condition but the cause is not fully understood. It is part of a trilogy of allergic diseases known as atopic allergies. These are asthma, eczema and hayfever. All three have a genetic association which means that there is often a family history of one or more of them.

In addition to the genetic connection there are a number of recognised factors that can start an asthma attack. Common triggers include:

• house dust mite, animal fur, pollen
• exercise, tobacco smoke, fumes
• changes in the weather
• viral infections, eg. a cold
• stress

Rarely some foods, eg nuts and shellfish, or food additves, eg tartrazine, can trigger asthma.

What can I do to help my asthma?
If you suffer from asthma it is important to discuss with your GP how to manage your asthma and what medicines are appropriate. Asthma can deteriorate quickly and become life-threatening so never delay in seeking help if you feel things are getting out of control.
Regarding your lifestyle, try to avoid the factors that may be triggering your asthma. This includes reducing contact with anything that you're allergic to, such as animal hair or pollen. Try to reduce house dust mite exposure if you have a house dust mite allergy (mattress covers, vacuum cleaners with allergy filters and damp dusting will help). Avoid general irritants, such as tobacco smoke where possible, and of course, DO NOT SMOKE.

Most people with asthma can eat a normal diet, although occasionally some need to avoid allergic triggers, such as cow’s milk, eggs, fish, shellfish, yeast products, nuts and some food colourings and preservatives.

There is no reason to avoid sports. Many professional sportsmen and women have asthma and manage by careful use of their medication before exercise.
Asthma cannot be cured but it can be controlled
