What Causes Varicose and Spider Veins?

The main reason why you may be noticing that you are developing spider or varicose veins is often a genetic predisposition or a hereditary trait that weakens your vein walls and valves, with a 60-80% chance of someone in your family having the same venous disorder. In addition, conditions such as a sedentary lifestyle, pregnancy or birth control, obesity, aging or long periods of inactivity during your day to day life can cause or accelerate the disease.
