Complications of Asthma

Occasionally, asthmatics may experience symptoms getting suddenly worse, or steadily worsening over a period of days. Signs that asthma is getting out of control may include:

  • Waking at night with coughing, wheezing, shortness of breath or a tight chest
  • Having to take time off work because of your asthma
  • Finding it difficult to breathe, and breathing short shallow breaths
  • Needing more and more reliever treatment (treatment that helps symptoms); using it more frequently than every 4 hours
  • Finding that your reliever does not seem to be working
  • Feeling unable to keep up with usual levels or activity or exercise

Very rarely, a person with asthma will have a severe attack in which none of the treatments work and the attack continues to get worse. This can be life-threatening.

This condition calls for urgent medical attention at any time of the day or night. The same applies to a steady worsening, when treatment seems to be working less and less.

The risk of death from asthma can be increased by the following factors: 

  • A previous near-fatal episode of asthma
  • Abrupt development of symptoms that respond poorly to treatment and that rapidly progress 
  • Asthma attack with a rise in the level of carbon dioxide in the blood (detected by blood tests or if the lips had turned blue-grey)
  • Not being aware how severely the airways have become blocked
  • Clear daily variations in ease of air flow 
  • Frequent hospital admissions or emergency visits
  • Recent increased frequency of night-time awakenings or daytime breathing difficulty
  • Failure to diagnose asthma or to provide adequate treatment, or failure to ensure the patient can cope with self-care measures.

Asthma can also reduce quality of life if not properly controlled, causing tiredness, underperformance at school, and time off school or work. It can cause psychological problems when a child is stigmatised or bullied for needing an inhaler, and it may reduce the growth rate and final height to which a child grows.
