What condition is often associated with increased risk of venous thromboembolism during pregnancy?

Obesity is indeed significantly associated with an increased risk of venous thromboembolism (VTE) during pregnancy. This risk is attributed to several factors related to obesity, including the presence of pro-inflammatory states, increased venous pressure due to weight, and alterations in coagulation profiles. During pregnancy, the body naturally undergoes hemostatic changes that enhance clotting to prevent excessive bleeding during childbirth. However, in individuals with obesity, these changes may become more pronounced, leading to a higher likelihood of clot formation.

Pregnant individuals with obesity also experience decreased mobility and may have associated medical conditions that further elevate their risk, such as hypertension or diabetes. Understanding these risks is crucial for prenatal care, as preventative measures can be implemented, such as increased monitoring or interventions like the use of compression stockings or anticoagulant therapy, particularly in those identified as high-risk. Recognizing the correlation between obesity and VTE risk can significantly influence treatment and preventive strategies during pregnancy.
