What causes low blood platelets in pregnant women?

There are many causes of thrombocytopenia in pregnant women: first, the most common cause of thrombocytopenia during pregnancy is idiopathic thrombocytopenia, which is called idiopathic thrombocytopenia during pregnancy. The cause is unclear, and may be related to changes in the immune system after pregnancy. Generally, it has little effect on pregnant women and fetuses, so there is no need to worry too much. Secondly, it may be a blood system disease caused by the suppression of bone marrow hematopoietic function, such as idiopathic thrombocytopenia purple epilepsy. For hematological diseases caused by abnormal hematopoietic function, different treatments should be made according to different blood diseases. Generally, pregnant women who show thrombocytopenia should pay attention throughout pregnancy and try not to fall. Because in case of injury, it will cause internal organ bleeding. When giving birth, or during cesarean section, platelet supplementation is necessary, otherwise it is easy to cause postpartum hemorrhage and intraoperative massive hemorrhage.
