Chronic venous insufficiency and the varicose veins and spider veins that it causes may not be curable with vein treatment alone. You may have hereditary factors that put you at risk for the development of new varicose or spider veins. What your vein specialist focuses on in your treatment plan is the elimination of distended, unsightly, uncomfortable veins. The underlying cause of venous insufficiency may be addressed to some extent with your lifestyle choices. After undergoing vein treatment, your doctor may discuss ways that you can reduce your risk of new veins developing. Examples include wearing compression stockings while working or exercising, elevating your legs at the end of the day, and maintaining a healthy weight.
