Key points
- 1
Varicose veins are swollen, twisted veins that often appear on the legs during pregnancy, caused by increased blood volume, hormonal changes that relax vein walls, and pressure from the growing uterus on the veins carrying blood back from the legs. They can also develop around the vulva in some pregnancies.

What is Varicose Veins in Pregnancy?
Varicose veins are swollen, twisted veins that often appear on the legs during pregnancy, caused by increased blood volume, hormonal changes that relax vein walls, and pressure from the growing uterus on the veins carrying blood back from the legs. They can also develop around the vulva in some pregnancies.
They're usually more of a cosmetic concern than a health risk, though they can cause aching, heaviness, or discomfort in the legs, especially after long periods of standing. They often improve, though don't always fully disappear, after birth.
02 · Understand
Clinical context
Compression stockings can genuinely help
Properly fitted compression stockings support circulation in the legs and can meaningfully reduce the discomfort and appearance of varicose veins during pregnancy.

Practical steps
Distinguish Discomfort from Signs of a Blood Clot
Ordinary varicose vein discomfort is usually a dull ache or heaviness. Sudden pain, redness, warmth, or swelling — especially in one leg — needs prompt medical assessment to rule out a blood clot.
- 1Wear compression stockings.These support circulation and can reduce swelling and discomfort — ask a pharmacist about proper fitting.
- 2Elevate your legs when resting.This helps blood flow back toward the heart and reduces pooling in the veins.
- 3Avoid standing or sitting for long periods.Move regularly to support healthy circulation.
- 4Stay active with gentle exercise.Walking and other pregnancy-safe activity support healthy blood flow in the legs.
- 5Avoid crossing your legs when sitting.This can further restrict blood flow in veins already under pressure.

BarnMD Bottom Line
Varicose veins are a common and usually harmless part of pregnancy, often improving somewhat after birth.
Sudden pain, redness, or swelling in one leg is different from typical varicose vein discomfort and should be checked promptly.
