Varicose veins, also known as spider veins, are vascular diseases in which the body’s regular veins protrude, curl, and become reddish or bluish in colour, and are located in the superficial parts of the body (immediately below the skin surface). After a certain age, these conditions become very normal (60 in most cases). These veins typically have a diameter of more than 3 mm and are found on the inner portions of the calves and thighs. They shape mainly as a result of valve failure (valve reflux) and vein wall weakening (loss of elasticity).
These disorders induce backflow of blood in these veins, resulting in abnormal bulges in various parts of the body (due to the accumulation of venous blood). Varicose veins are a form of varicose vein that affects the body’s superficial veins and appear as distorted, lumpy windings bulging out of the skin’s surface. While spider veins and varicose veins are also confused, spider veins are smaller in diameter (less than 1 mm).
