Which group is at higher risk for DVT during pregnancy?

During pregnancy, several physiological changes occur in a woman's body, including increased blood volume, changes in hormone levels, and reduced venous return due to pressure from the growing uterus. These factors contribute to a higher risk of developing deep vein thrombosis (DVT).

Obese individuals face additional risks because excess body weight can further compress veins, particularly in the pelvic and lower extremity areas. This compression can lead to slower blood flow and increased venous stasis, both of which are significant risk factors for DVT. Additionally, obesity is often associated with other comorbidities that can exacerbate the risk of thromboembolic events during pregnancy.

On the other hand, young adults, athletes, and senior citizens do not typically face the same risk levels as obese individuals during pregnancy. While age can influence DVT risk, younger individuals generally have more resilient vascular systems and are less likely to develop complications associated with pregnancy compared to those who are obese. Athletes, while they may be physically fit, might not be significantly impacted by the physiological changes of pregnancy in the same detrimental way as those with obesity. Despite some risks for older adults, the combination of obesity and pregnancy poses a far greater overall risk for DVT.
