Aggregation of platelets during pregnancy is one of the most important indicators, the reduction of which can contribute to bleeding. Aggregation in medicine refers to the ability of platelets to join, i.e., gluing blood platelets.
This process is as follows. If the walls of the vessels are damaged, blood begins to flow from them to prevent the consequences, the body sends an alarm to the cells. As a result, at the site of damage, platelets appear and, gluing together, close the gaps in the vessel.
To determine this indicator, a coagulogram is carried out-a blood test using a laboratory method using inducers-special substances that provoke aggregation. The norm of aggregation of platelets during pregnancy when interacting with any of these substances is 30-60%.
Hypoaggregation of platelets during pregnancy
Reduction of platelet aggregation during pregnancy can occur due to increased destruction or consumption of blood platelets. The causes of this can be frequent bleeding, a violation of the body's immune system, or an improper diet of a pregnant woman. Hypoaggregation of platelets during pregnancy is expressed by symptoms such as bruising and bleeding. In such cases, blood plates are produced in very small amounts, or acquire an irregular structure. In childbirth such an indicator of blood coagulability can lead to severe bleeding.
Hyperaggregation of platelets during pregnancy
A slight increase is considered a natural process in the period of gestation - this is associated with utero-placental circulation. Hyperaggregation of platelets during pregnancy can provoke the formation of thrombi. Thrombosis, arterial or venous, may be accompanied by an antiphospholipid syndrome, which is often the cause of miscarriages in the early stages.
