Keeping mum

During pregnancy your heart has to pump 50% harder than normal – and that's just one of the changes to expect.

The body makes a series of fantastic adaptations during pregnancy, many of them almost as impressive as the new life growing in the womb.

What problems are common?
Many pregnant women develop heart murmurs, due to the increased blood flow. Normally this isn’t a problem, and your doctor can determine whether it needs further attention or not.

  • difficulty breathing, especially at night
  • shortness of breath during normal activities
  • light-headedness or fainting
  • palpitations (irregular heartbeat)
  • heart murmur or click
  • enlarged heart (more than the normal enlargement with pregnancy)
  • cyanosis (blue-colouring due to low levels of oxygen in the blood).
