Anaemia (iron deficiency) occurs when the levels of iron in your blood become too low. If you experience heavy bleeding, it can cause anaemia, which in turn causes a range of symptoms including fatigue.


Anaemia is usually caused by blood loss such as that experienced during heavy periods. If you think you have anaemia you should speak to your GP.


Anaemia can cause a range of symptoms which can include:

  • Tiredness (fatigue) and lack of energy
  • Dizziness
  • Mood swings
  • Shortness of breath
  • Noticeable heartbeats (heart palpitations)
  • Pale skin
  • Hair loss (alopecia)

In addition, if your iron levels are too low, it can affect your immunity, making you more susceptible to illness. Your overall health may also deteriorate.

If you think you have anaemia, book an appointment with your GP. If you think this is related to heavy periods, read about how to prepare for your GP appointment here.
