Varicose veins are abnormal dilations of veins visible under the skin. They cause unpleasant symptoms, including a feeling of heavy legs. Among the risk factors for varicose veins: heredity and lifestyle. To preserve the venous capital of your legs, you can adopt some preventive measures on a daily basis. Sciences et Avenir takes stock.

Chronic venous insufficiency, which leads to varicose veins, affects three women for every man. These circulation problems are in fact more frequent and often early in women.

But what is it about? The venous network of the legs is made up of a so-called “deep” network, and a so-called “superficial” network. The latter is the site of varicose veins, the dilations visible under the skin. Often, they are due to a malfunction of the valves, responsible for blood flow within the veins. To promote venous return and get the calf muscle pump working, doctors recommend several simple actions.

Why do we have varicose veins?

Varicose veins are observed on the superficial network of veins located under the skin. It represents 10% of the venous blood transported. Deeper, in the muscles, another network of veins transports 90% of venous blood. Most often, varicose veins appear in the saphenous veins just under the skin. The greater saphenous vein goes up to the groin to join the deep network, and the small joins it behind the knee. “Thus, varicose veins can be visible on the leg, but also on the thigh up to the groin. specifies the Health Insurance website.

Thanks to several mechanisms, the blood circulating in the veins defies gravity and rises towards the heart. The contraction movements of the calf in particular act like a pump. The pressure exerted on the veins of the foot when we walk also helps propel the blood. Inside the veins, valves prevent blood from flowing backward, thus ensuring a unidirectional flow. But when these fail, the blood returns against the current and then stagnates in the veins, which dilate: these are varicose veins.

Warning symptoms

Before varicose veins, several symptoms can occur, as the Ameli website points out:
