The decrease of the platelets below their normal count i.e. from 150,000 to 400,000 is called thrombocytopenia. If not treated in time, it can be fatal. The three main causes of thrombocytopenia are reduced production of platelets, increase in destruction of the platelets and sequestration. The causes for decrease in the platelets are aplastic anemia, HIV infection, and exposure to chemotherapy, cirrhosis of the liver, leukemia, vitB12 deficiency and deficiency of iron. The symptoms usually include internal bleeding i.e. bleeding of gums, rectum, nose, wounds and blood in stool, urine and vomit. During pregnancy, there may be a mild decrease in platelet count, but it shows no symptoms.
HOW IS LOW PLATELETS DIAGNOSED?
Thrombocytopenia affects a few percent of newborns and its prevalence in neonatal intensive care is high.
