Spider veins and varicose veins develop from damaged valves that prevent blood from flowing normally. Many other things can damage your valves, but your risk of varicose veins and spider veins is higher if you have a family history of the issue. One of the most common causes is genetics. If your close relatives have visible veins, that means you are more likely to develop them yourself. Other risk factors include hormones, age, pregnancy, lifestyle, and weight.
If you are concerned about spider or varicose veins, talk to our dermatologist. She can help you identify the cause and find the best treatment option for you.
