Varicose Veins
Varicose veins are enlarged veins that are visible under the skin, often appearing blue or purple. They primarily occur on the legs due to poor venous return. When the valves in the veins malfunction, blood pools, leading to vessel dilation. Several factors contribute to their development: heredity, prolonged standing, lack of physical activity, pregnancy, or hormonal fluctuations. While they are often harmless, they can cause pain, heaviness in the legs, and complications such as venous ulcers.
