Asthma
Asthma — living well with it under control
What asthma is
It is a condition with long-lasting inflammation in the airways, so wheezing, sudden coughing fits, tightness in the chest and difficulty breathing keep coming back. The goal is 'a well-controlled state' rather than a cure, and with steady inhaler treatment most people can live and exercise normally.

Inhalers are the heart of treatment
- Controllers (including inhaled steroids) are medicines you use every day, even when you have no symptoms. Stopping them on your own brings the attacks back
- Using only the reliever (a fast-acting bronchodilator) over and over is a warning sign
- If your inhaler technique is wrong, the medicine does not reach your lungs. Have your technique checked in person at your appointment
- Colds and flu are common triggers for a flare-up, so keep up with your vaccinations

What to do during an asthma attack
- Use your reliever and rest sitting up
- If the reliever does not help, or you cannot get your words out and your lips turn blue, call 119 immediately
- If attacks become more frequent, it means your treatment step needs adjusting, so bring your appointment forward

Frequently asked questions
I am worried about side effects from inhaled steroids
An inhaler delivers a very small dose that acts directly on the airways, so whole-body side effects are incomparably fewer than with steroid tablets. Rinsing your mouth after use also prevents voice changes and oral thrush. Asthma that is not controlled is far more dangerous than the steroid.
