Varicose Veins During Pregnancy

Varicose veins during pregnancy are extremely common, and for many people they are the first time they notice bulging, visible veins in their legs. The changes that pregnancy brings to your circulatory system make this a predictable, if uncomfortable, part of the experience for many. Here is what is actually happening in your body and what you can do about it safely.

Why Pregnancy Increases the Risk of Varicose Veins

Several things happen simultaneously during pregnancy that raise the likelihood of varicose veins. Blood volume increases significantly to support the growing baby, which places more pressure on vein walls. Hormonal changes, particularly rising progesterone, relax the walls of blood vessels, making them more prone to stretching. As the uterus grows, it puts direct pressure on the large vein that returns blood from the legs to the heart, slowing circulation. Weight gain adds further pressure on the lower body's veins, and this combination of factors is why so many people notice new veins during pregnancy even without a strong prior family history. The NHS has more detail on why pregnancy is such a common trigger.

When Do Varicose Veins Typically Appear?

Many people first notice varicose veins in the second or third trimester, when the growing uterus places more pressure on pelvic and leg veins, though they can appear earlier for some. Veins that appear during pregnancy also tend to be more common in the legs, but some people notice them in the vulva or pelvic area as well, which is also related to increased local blood volume and pressure.

Are Varicose Veins During Pregnancy Dangerous?

For most people, pregnancy-related varicose veins are uncomfortable but not medically dangerous. They often improve on their own in the months after delivery as blood volume and hormone levels return to baseline. That said, you should contact your doctor promptly if you notice one leg becoming significantly more swollen, red, or warm than the other, as this can occasionally signal a blood clot that needs urgent evaluation, especially during and after pregnancy when clot risk is naturally elevated.

Safe Ways to Manage Symptoms

Because many treatments are not recommended during pregnancy, management typically focuses on conservative, low-risk approaches.

Wear Pregnancy-Safe Compression Socks

Graduated compression stockings designed for pregnancy are one of the most commonly recommended tools. They apply gentle pressure to support circulation without restricting the abdomen, and many people find they reduce end-of-day heaviness and swelling. If you're unsure what strength or style to choose, our compression socks buying guide covers mmHg levels and sizing to help you pick a suitable pair.

Elevate Your Legs When Possible

Resting with your legs elevated above your heart for short periods during the day can help ease pooling and swelling, and it is a habit that is easy to combine with other rest breaks throughout pregnancy.

Change Positions Often

Avoid standing or sitting in one position for long stretches. If your job requires long periods of standing or sitting, take breaks to walk or shift position regularly.

Sleep on Your Left Side

Many doctors recommend sleeping on your left side during later pregnancy, which can relieve pressure on the large vein on the right side of your body and support better circulation.

Stay Active

Gentle, doctor-approved activity such as walking or prenatal yoga can support circulation without putting undue strain on your body, and staying active throughout pregnancy has benefits well beyond vein health alone.

What Happens After Delivery?

Many pregnancy-related varicose veins shrink or fade noticeably in the months following delivery as blood volume decreases and hormone levels normalize. If veins remain bothersome or visible well after delivery, it is worth discussing treatment options with a doctor once you have fully recovered, since procedures that are not appropriate during pregnancy or breastfeeding may become reasonable options later.

Always check with your OB-GYN or midwife before starting any new supplement, cream, or treatment during pregnancy, since not everything considered safe for the general population is appropriate during pregnancy or breastfeeding.
