Symptoms

Most children and adults with asthma find they have times when their breathing becomes more difficult.

Some people with more severe asthma may have breathing problems most of the time.

Main symptoms

The most common symptoms of asthma are:

  • wheezing (a whistling sound when breathing)
  • Shortness of breath
  • a tight chestwhich may feel likea band is tightening aroundit
  • coughing

These symptoms can have a number of causes, but they're more likely to be asthma if they:

  • happen often and keep coming back
  • are worse at night and early in the morning
  • seem to occur in response to an asthma trigger for example, exercise or exposure to an allergen (such as pollen or animal fur)

Asthma attacks

Asthma symptoms can sometimes get worse for a short time known as an asthma attack. This can happen suddenly, or gradually over a few days.

Signs of a severe asthma attack include:

  • wheezing, coughing and chest tightness becoming severe and constant
  • being too breathless to eat, speak or sleep
  • breathing faster
  • a rapid heartbeat
  • drowsiness, confusion , exhaustion or dizziness
  • blue lips or fingers
  • fainting

If you've been diagnosed with asthma, your reliever inhaler (usually blue) maynot help and your peak flow reading may be much lower than normal.
