In which scenario might a pregnant woman need anticoagulation therapy?

A pregnant woman may need anticoagulation therapy in situations where there is a history of venous thromboembolism (VTE). VTE encompasses conditions such as deep vein thrombosis (DVT) and pulmonary embolism (PE), which can occur during pregnancy due to physiological changes that increase the risk of blood clot formation. Pregnancy is a hypercoagulable state, which means that the blood clotting mechanism is enhanced, making individuals with a history of VTE particularly vulnerable to developing clots again.

Anticoagulation therapy is utilized to reduce the risk of clot formation and prevent serious complications associated with VTE, such as life-threatening pulmonary embolism. It's essential for healthcare providers to assess a woman's medical history carefully to determine the need for such therapy, especially in cases where previous thrombotic events have occurred.

Other scenarios listed—such as gestational diabetes, hypertension, and ongoing morning sickness—do not directly indicate a need for anticoagulation therapy. While these conditions can present risks during pregnancy, they do not inherently relate to an increased risk of venous thromboembolism, which is the specific reason anticoagulation would be indicated.
