What Bulging Veins May Be Telling You

Bulging veins aren’t always dangerous, but sometimes they signal an underlying health issue. Veins become more visible when blood pools in weakened or damaged veins instead of flowing smoothly back to the heart, often causing varicose veins—swollen, twisted veins usually found on the legs but sometimes on the arms.

Common causes include aging, genetics, excessive exercise, hot weather, tight clothing, sun exposure, and being overweight. Hormonal changes, especially during pregnancy, smoking, and long periods of standing or sitting can also trigger varicose veins.

If you notice bulging veins with discoloration, it’s important to see a healthcare provider. Treatments range from compression stockings and leg elevation to injection therapy and vein surgery, depending on severity.

Untreated varicose veins may lead to complications like venous ulcers or blood clots, which can cause serious conditions such as deep vein thrombosis or pulmonary embolism.

To reduce your risk, stay active, maintain a healthy weight, quit smoking, and avoid tight clothing around the waist.
