Which condition is considered a minor risk factor for venous thromboembolism during the postpartum period?

Preeclampsia is a condition characterized by high blood pressure and signs of damage to other organ systems, often occurring after the 20th week of pregnancy. While it does pose risks during the postpartum period, particularly due to potential complications such as increased blood clotting tendencies, it is typically considered a more significant risk factor for venous thromboembolism (VTE) than some other conditions.

In contrast, conditions like obesity, prolonged labor, and multiple gestation are better categorized as minor risk factors in the context of VTE. For example, obesity significantly increases the risk of VTE due to factors such as reduced mobility and increased body weight putting additional pressure on veins. Prolonged labor can also be associated with increased risk due to extended immobility and other physiological changes. Multiple gestation, while it does carry some risk, often does not have the same level of association with thrombosis compared to the other risk factors mentioned. Therefore, while preeclampsia is an important concern in the postpartum period, it does not qualify as a minor risk factor in the same way the others do.
