People with thrombocytopaenia (also spelt thrombocytopenia) have too few platelets, which are cells found in the blood that control bleeding. Thrombocytopaenia can cause bleeding problems. Treatment depends on the severity of the thrombocytopaenia.

What is thrombocytopaenia

In thrombocytopaenia, platelets (also called thrombocytes) are low in number, which can result in bleeding problems. Platelets are blood cells important for helping blood to clot. Platelets may be low in number if there is not enough of them being made, if they are being destroyed or if they are being trapped in the spleen. The spleen is an organ that sits in your abdomen, under the ribs on the left.

Causes of thrombocytopaenia

Thrombocytopaenia may be due to:

Thrombocytopaenia symptoms

People with thrombocytopaenia can:

  • bruise easily
  • have nose bleeds or bleeding gums
  • have pinpoint bleeding in the skin that looks like a rash (known as petechiae)
  • have cuts that keep bleeding
  • feel tired.

In rare cases, dangerous internal bleeding may occur.

If you are worried that you or your child has thrombocytopaenia, visit your doctor.

For bleeding that won’t stop, go to your local emergency department or call triple zero (000).

Thrombocytopaenia diagnosis

Your doctor will examine you and probably order blood tests. If you have thrombocytopaenia, blood tests show a low platelet count.

You may have other tests to investigate the cause of the thrombocytopaenia, and your doctor may refer you to a specialist.

Thrombocytopaenia treatment

Depending on the cause and severity of the thrombocytopaenia, treatments may include:

  • watching and waiting, as thrombocytopaenia often gets better by itself
  • treating the cause, for example, treating an underlying cancer, or stopping medications that can cause thrombocytopaenia
  • steroids to boost platelet numbers.

In more severe cases, you may need:

  • platelet transfusion
  • intravenous gamma globulin (a type of blood transfusion)
  • surgery to remove the spleen.

You may also have to:

During treatment, you will need regular blood tests and reviews with your doctor.

Depending on the cause and severity, thrombocytopaenia often improves in a couple of weeks, but can take six to 12 months or longer in some people.
