Is it common for women to develop both varicose veins and spider veins? Dr. Luis Navarro: Between 60 and 80% of women who has varicose veins have spider veins also. So, it’s very common to have both expressions of the disease, we can say. And of course, when somebody has varicose veins, the varicose veins are more important aspect of the disease so that’s what you usually will treat first, but then of course you need to take care of the spider veins for cosmetic reasons.
