Thrombocytopenia (low platelet count) definition and facts

  • Thrombocytopenia or low platelet count is a lower than normal number of platelets (less than 150,000 platelets per microliter) in the blood.
  • Thrombocytopenia may be inherited or acquired when conditions occur, such as the use of certain drugs.
  • Causes of thrombocytopenia can be classified in three groups:
    • Diminished production (caused by viral infections, vitamin deficiencies, aplastic anemia, drug induced)
    • Increased destruction (caused by drugs, heparin [HIT], idiopathic, pregnancy, immune system)
    • Sequestration (caused by enlarged spleen, neonatal, gestational, pregnancy)
  • Thrombocytopenic symptoms may include:
    • Petechiae (superficial tiny areas of bleeding into the skin resulting in small reddish spots)
    • Fatigue
    • Purpura (easy or excessive bruising)
    • Prolonged bleeding cuts
    • Spontaneous bleeding from the gums or nose
    • Jaundice
    • Heavy menstrual bleeding that's unusual for the female
    • Blood in the urine or stools
    • Enlarged spleen (splenomegaly)
    • Bleeding that will not stop
    • DVT (deep vein thrombosis)
  • Individuals should seek medical care if they have one or more these symptoms.
  • Doctors that may be consulted for thrombocytopenia include emergency medicine, internal medicine, hematologists, and immunologists.
  • Diagnosis of thrombocytopenia is confirmed by blood tests that determine platelet count.
  • Treatment of thrombocytopenia varies depending on the cause and the severity of the condition.
  • Complications of thrombocytopenia can be severe (organ damage and death).
  • Depending upon the cause, thrombocytopenia may be prevented. However, many causes may not be preventable.
  • If treated early and effectively, the prognosis for thrombocytopenia is usually good. However, if diagnosed later in the disease process, or if HIT is the cause, the prognosis decreases.
