Sometimes the same factors that helped to cause your first spider veins or varicose veins (e.g., family history, age, obesity, female hormones, etc.) will make you predisposed to develop additional vein conditions. If a specific vein is properly treated, it usually does not recur, but it is possible that other veins may become diseased. This is why it is important that even if you have what appear to be simple, cosmetic spider veins, that you consult a vein specialist who can determine if you have an underlying condition (venous reflux). If you do, and you don’t treat the cause of the problem, additional spider veins or varicose veins are likely to develop.
