As mentioned above, pregnancy is a risk factor for developing spider veins. In particular, the hormonal changes that come with pregnancy, and then after pregnancy, add stress on the veins and make them more vulnerable to venous insufficiency.
Family history of spider veins or varicose veins
If people in your family have had spider veins or varicose veins, it’s more likely that you will develop the same or similar vein problems.
History of sunburns, tanning, or the use of tanning beds
As mentioned earlier, sun damage is one of the reasons spider veins can develop. When the tiny capillaries near the surface of your skin on your face or legs are exposed to UV radiation from the sun or tanning beds, they can become damaged. And over time, these capillaries may become spider veins.
Keep in mind that these are only the known risk factors. Both men and women of any age may develop spider veins. Finally, it is also possible to develop spider veins as a side effect of receiving vein surgery.
