Which of the following factors may worsen symptoms of chronic venous insufficiency?

Prolonged standing or sitting is a significant factor that may worsen the symptoms of chronic venous insufficiency (CVI). When an individual stands or sits for extended periods without movement, blood can pool in the lower extremities due to gravity, leading to increased venous pressure. This buildup of pressure can exacerbate symptoms such as swelling, discomfort, and pain in the legs. In the context of CVI, the venous valves may already be compromised, and prolonged static positions can hinder blood flow back to the heart, thereby worsening the condition.

In contrast, increased physical activity typically promotes venous return and can alleviate symptoms, while regular use of compression stockings helps prevent blood pooling and improves circulation. Similarly, elevating the legs is a beneficial practice for CVI patients, as it aids in reducing swelling and improving venous drainage. These options are supportive measures that contribute positively to managing chronic venous insufficiency.
