You may be:
- needing more and more reliever treatment
- waking at night with coughing, wheezing, shortness of breath or a tight chest
- having to take time off school/college/work because of your asthma feeling that you cannot keep up with your normal level of activity or exercise.
Any of these show that your asthma is not controlled and you should see your doctor or asthma nurse to get your asthma back under control.
These videos about asthma and living with it were made by Asthma UK.
