How do varicose veins affect blood pressure?
Varicose venis cause blood pressure of veins to increase
Blood from veins flows from lower parts of the body to heart. To push blood from legs to heart veins have valves. If these valves are damaged or weak blood is accumulated in lower limbs due to gravity.
This causes swelling of surface veins. Accumulated blood in lower limbs causes venous hypertension. From veins plasma leaks out of blood vessels. .
