Understanding Thrombocytopenia: Causes and Warning Signs

Platelets are crucial for blood clotting and preventing excessive bleeding. Normally, platelet levels range from 150,000 to 350,000 per microliter of blood. Due to their tiny size, platelets comprise a tiny fraction of blood volume. Recognizing symptoms of low platelet counts, or thrombocytopenia, is essential for early intervention.

Signs to watch for include:

  • Unexplained bruising or purpura
  • Prolonged healing of cuts
  • Blood in urine or stools
  • Persistent fatigue
  • Enlarged spleen
  • Heavy menstrual bleeding
  • Bleeding gums or nasal bleeding

Next, let's explore common causes behind decreased platelet levels.

Thrombocytopenia Causes and Symptoms
  • Medication and Substance-Induced Causes: Certain medications such as heparin, eptifibatide, and glycoprotein inhibitors can reduce platelet counts. Over-the-counter drugs like aspirin, ibuprofen, and naproxen may also contribute. Harmful substances like pesticides, arsenic, benzene, or excessive alcohol intake can impair platelet production. Quinine-containing drinks or tablets for leg cramps are known offenders.
  • Medical Conditions: Several health issues can lead to low platelets. These include reduced production in the bone marrow due to leukemia, other cancers, or blood disorders like anemia. Viral infections such as hepatitis C and HIV can suppress platelet counts. An enlarged spleen trapping platelets is another cause. Pregnancy may temporarily lower platelet levels, which typically normalize postpartum.
