What are the seven causes of varicose veins in the lower limbs? Varicose veins in the lower limbs are divided into two major categories: primary and secondary. There are many reasons for the formation of varicose veins, but the fundamental causes include the weakness of the walls of the superficial veins or the insufficiency of valve closure, as well as the persistent elevation of pressure within the veins leading to vein dilation. Additionally, poor function of the valves inside the veins, increased venous pressure, venous obstruction, and venous compression contribute to this condition. Specifically, there are the following reasons:
1. Genetic factors. Among patients with primary varicose veins in the lower limbs, almost 70% have a family history. This is mainly related to the inherent weakness of the superficial vein walls and defects in the venous valves within the family. Therefore, family members with a history of varicose veins in the lower limbs should pay special attention to protecting their own lower limb veins.
2. Long-term engagement in standing work. Such as textile workers, mechanics, teachers, salespeople, etc., due to prolonged standing, it causes a persistent increase in pressure within the superficial veins, damaging the valves within the veins, causing the blood in the lower limb veins to flow backward and forming this disease.
3. Long-term engagement in heavy physical labor. Such as workers involved in loading/unloading, transportation by tricycle, farmers, etc., who have a higher incidence rate. This is mainly because the intra-abdominal pressure increases during heavy lifting, hindering the return flow of blood in the lower limb veins, increasing venous pressure, and eventually leading to poor function of the venous valves and forming this disease over time.
4. Pregnancy. During pregnancy, the abdominal pressure increases, hindering the return flow of blood in the lower limb veins and forming this disease, especially in cases of multiple pregnancies or multiple births.
5. Formation of deep vein thrombosis in the lower limbs. Due to the blockage caused by the thrombus in the deep veins of the lower limbs, the return flow of blood in the lower limb veins is obstructed, increasing the burden on the superficial veins, causing gradual dilation of the superficial veins, and eventually forming this disease over time.
6. Primary insufficiency of the deep venous valves in the lower limbs leads to the reverse flow of venous blood, which is also a common cause of varicose veins.
7. Compression from tumors in the pelvic cavity and congenital vascular developmental abnormalities can also lead to varicose veins in the lower limbs.
