The veins in your legs have a difficult job. The blood that travels into your legs through the arteries has the force of your heartbeat behind it. After it delivers its oxygen and supplies, that blood must return to your heart and lungs. Transporting blood through the long veins of the legs puts them under strain, leading to leg vein problems that can affect your health if not diagnosed and treated.
What Causes Leg Vein Problems?
Many factors contribute to the development of leg vein problems. The central issue is that your leg veins have one-way valves to keep blood moving up your legs. If those valves weaken, blood can pool in the veins, stretching and damaging them.
When you have stretched, malfunctioning leg veins, the condition is called venous insufficiency. This damage results in twisted, discolored varicose veins, but it also affects veins deep within the leg. You may develop varicose veins if:
- You have a family history of the condition
- You spend long periods of time standing or sitting
- You have certain other health problems
- You do not get much physical activity
- You experience hormonal changes such as pregnancy or menopause
