Varicose Veins Affect 1 in 5 Adults, Women Most at Risk
Varicose veins—enlarged, twisted veins often seen on the legs—affect about 20% of adults, according to the NIH. Caused by faulty vein valves that disrupt blood flow, they can lead to discomfort and cosmetic concerns. Women are more commonly affected due to hormonal shifts and pregnancy.
Key risk factors include aging, prolonged standing or sitting, obesity, genetics, and hormonal changes.
