What causes varicose veins? Varicose veins are relatively common in clinical practice. The course of the disease can be very long, lasting for decades in some cases. So, why do people develop varicose veins? Below, we will invite experts from Shanxi Yikang Peripheral Vascular Hospital to introduce this topic.
For the causes of varicose veins, the condition is due to weak venous walls, defective venous valves, and prolonged elevated pressure in superficial veins, which leads to blood reflux and expansion of superficial veins. Over time, this can result in complications such as leg ulcers and bleeding. Varicose veins in the lower limbs also belong to a category of occupational diseases, caused by prolonged standing. For example, shop assistants, textile workers, teachers, and nurses have higher incidence rates. If it's mild, one can take precautions by resting and wearing compression stockings; severe cases require surgical treatment. Varicose veins are believed to be associated with prolonged standing, infections, and thrombosis, all of which affect the circulation of blood in the lower limbs.
Another cause of varicose veins is congenitally weak vascular membranes or maintaining the same posture for extended periods without change, leading to blood pooling in the legs. Over time, this damages the venous valves, resulting in high venous pressure, causing the vessels to protrude through the skin. Varicose veins most commonly occur in the lower limbs, but they can also occur in other areas such as the scrotal spermatic cord, abdominal veins, and esophageal veins in the stomach. This is because the blood in the leg veins needs to flow from a lower position to a higher one to return to the heart, which goes against physical principles. This process relies on many valve-like structures within the veins that function like gates, allowing blood to flow towards the heart while preventing reverse flow.
