About Asthma – triggers, symptoms, diagnosis, treatment and prognosis

on Tue 2 May

 

A common and long term lung condition, asthma affects about five million people in the UK. It’s actually not known what causes asthma but researchers currently believe it is a combination of genetic and environmental factors. 

 

Asthma occurs because the airways become inflamed and narrowed with an increased production of mucus in reaction to being more sensitive to certain triggers which may not bother other people. These triggers are very individual and sometimes difficult to identify because your symptoms don’t always occur immediately after exposure.

 

Common asthma triggers include:

  • Air pollutants such as smoke or fumes
  • Airborne irritants like pollen, moulds, dust mites, animal fur or feathers
  • Respiratory infections such as colds and flu
  • Cold air
  • Vigorous exercise
  • Strong emotions
  • Some medicines
  • Hormonal changes during pregnancy or the menstrual cycle
  • Sulphites/sulfites - used as preservatives in some foods

 

Symptoms

These vary from person to person but generally include:

  • Tightness in the chest
  • Wheezing
  • A cough during the day or night
  • Shortness of breath
  • Difficulty speaking
  • Blue lips
  • Feeling distressed

 

Asthma in Children

Although it is commonly believed that children grow out of asthma this is not strictly accurate.

 

Children under the age of five who wheeze from time to time may not actually have asthma but viral infections and these children will of course appear to have grown out of their “asthma”.

 

Children with recurrent symptoms at a young age often have a period of respite from adolescence but may again get asthma as adults if triggers occur later in life. For helpful information should your child be diagnosed with asthma please click here 

 

Diagnosis

Your GP will initially do a lung function test like spirometry which shows how much air you can exhale and how much you can retain in your lungs; and/or a peak flow test to see how much and how quickly you can blow air out of your lungs in one breath.

 

They will also look at your medical history and do a physical exam.

 

Treatment and Prognosis

Although asthma is chronic and cannot be cured, most people can lead normal lives with the right treatment.  This is likely to be a combination of long term treatment to reduce inflammation and quick relief or rescue medicines to relieve symptoms that have flared up.  This will usually take the form of an inhaler.

 

Monitoring and avoiding triggers will obviously also help considerably and providing you work closely with your doctor and follow your treatment regime it’s possible to control the condition and get on with living your life.
