No. People with a very low body-fat percentage (as manifested in many runners and body builders), have normal superficial veins that show through the skin because there is not enough subcutaneous tissue (i.e., fat) to hide them. Pronounced normal veins are most commonly seen on the inner aspect of the thighs and ankles, the inner and back areas of the calves, the arms and the back of the hands. To determine if protruding veins are normal or abnormal, both a venous duplex ultrasound and a physical examination are necessary.
