Can purple veins be a sign of illness?
In some cases, purple veins can be a sign of hidden health problems: Chronic venous insufficiency – When the venous valves do not function properly and blood stagnates in the veins, they dilate and change color.
Blocked arteries or vascular disease – Can contribute to the appearance of purple veins.
Leg injuries – Mechanical injuries can temporarily change the color of veins.
