What is the main cause of varicose veins? The primary cause of varicose veins is a condition known as venous insufficiency. In a healthy circulatory system, veins carry blood back to the heart, aided by one-way valves that prevent the blood from flowing backwards. However, when these valves weaken or fail, blood can pool in the veins, leading to increased pressure. This heightened pressure can cause the veins to become enlarged, twisted, and bulging, giving rise to varicose veins.
