By exercising on a regular basis, you can pump blood up to your legs and back to your heart against gravity. By working out frequently, adhering to a nutritious, well-balanced diet, and maintaining a healthy weight, you may be able to reduce your risk of varicose veins and improve your overall health. Keep in mind that unfortunately time and gravity may cause veins in some individuals to wear out over time. Once a varicose vein exists, it cannot function properly and should be treated as soon as possible.
