If you’re noticing swelling or varicose veins earlier in this pregnancy, you’re not imagining that it can feel different from the first time around. Pregnancy changes circulation in several ways, and research suggests the risk of varicose veins rises with each pregnancy. At the same time, many women tell us that a second pregnancy comes with less time to rest or put their feet up especially when there’s a toddler or older child to care for.
So why can the second time feel different? Here’s what may be adding up, what the evidence says, and the practical habits that can help support your legs throughout pregnancy.
Why Varicose Veins Can Feel Different in a Second Pregnancy
Your Veins Remember
Most pregnancy-related vein changes improve within 3 to 4 months after birth. But veins that have stretched, and valves that no longer close as efficiently, may have a harder time moving blood back up the legs when pregnancy places pressure on the venous system again. In that sense, ‘your veins remember’ is a useful way to describe the pattern: risk rises with each pregnancy.
A large 2022 study by DeCarlo and colleagues found that increasing parity was significantly associated with the development of varicose veins. Compared with women who had not been pregnant, the hazard was about 1.8 times higher after one pregnancy and nearly 5 times higher after six or more pregnancies. That does not mean every second pregnancy will cause varicose veins, but it does show that pregnancy history matters.
Hormones Change How Your Veins Work
Hormonal changes begin early in pregnancy and can soften the walls of your veins and affect how well the valves inside them work. As pregnancy progresses, your growing uterus also places pressure on the veins that return blood from your legs toward your heart. Blood volume rises too. Together, these changes can make blood more likely to pool in the lower legs, contributing to swelling and more noticeable varicose veins. Learn more about circulation and body changes in pregnancy.
Second Pregnancy Reality: Less Time to Put Your Feet Up
This isn’t a medical cause of varicose veins; it’s something women often tell us about the reality of a later pregnancy. When you’re caring for a toddler or older child, working, lifting, commuting or juggling more responsibilities, there may simply be fewer opportunities to stop and elevate your legs when they start to feel heavy or swollen. If your first pregnancy included more chances to rest, that lifestyle difference can make the second experience feel very different.
First Pregnancy vs This Time
In a first pregnancy, swelling or visible veins may appear later, or you may have more flexibility to respond when your legs feel tired. In a second or subsequent pregnancy, your veins have already been through pregnancy-related changes, and the same hormonal, circulatory and uterine pressures return. Add the everyday reality of chasing a toddler or spending more time on your feet, and symptoms may feel more noticeable even when the underlying pregnancy changes are familiar.
What Actually Helps
Varicose veins and swelling can be uncomfortable, but practical habits can help support circulation and make your legs feel more comfortable as pregnancy progresses. Pregnancy, Birth and Baby recommends measures such as elevating your legs, avoiding long periods of standing, staying active and using compression stockings during the day for pregnancy-related swelling. Read their guidance on swelling during pregnancy.
Wear graduated compression. Graduated compression applies the most pressure lower down the leg and gradually eases upward. During pregnancy, compression can be used to support circulation and help manage swelling. TheRY’s Saviour Maternity Compression Leggings and Maternity Compression Socks provide 15–20 mmHg graduated compression designed for pregnancy. NICE also notes that compression hosiery may be offered to relieve varicose veins during pregnancy. Read the NICE guidance.
Elevate. Put your feet up above heart level when you can. Even short periods of elevation can be a practical reset when your legs feel heavy after standing or moving through the day.
Move often. Gentle, regular movement helps keep your calf muscles working and breaks up long periods of sitting or standing. A short walk, changing position or moving your ankles can be easier to fit into a busy day than waiting for a long rest period.
Hydrate and choose comfort. Drink water throughout the day and choose comfortable clothing and footwear that do not feel restrictive. If swelling or varicose veins are bothering you, speak with your doctor, midwife or pregnancy care provider about what is appropriate for you.

When to Seek Medical Advice Urgently
Some swelling is common in pregnancy, but sudden or severe swelling needs attention. Seek medical advice urgently if you develop sudden swelling of your face, hands or feet, a severe headache, vision changes, or pain under the ribs. These can be warning signs of pre-eclampsia. You should also seek urgent medical advice if one leg becomes much more swollen than the other, particularly with pain, redness or warmth, as this can be a sign of a blood clot. See Pregnancy, Birth and Baby’s warning signs during pregnancy.
The Takeaway
If your second pregnancy feels different from your first, especially when it comes to swelling, heavy legs or varicose veins, there may be several reasons why. Hormonal changes affect the vein walls, your growing uterus adds pressure, blood volume increases, and research shows that varicose-vein risk rises with each pregnancy. The practical reality of having less time to rest can make those changes feel even more noticeable.
Support your legs from the very beginning.
Small habits such as regular movement, elevation above heart level, hydration and graduated compression can help support your legs as pregnancy progresses.

Frequently Asked Questions
Do varicose veins get worse with each pregnancy?
They can. Research suggests the risk of developing varicose veins rises with each pregnancy. DeCarlo et al. (2022) found an increasing hazard with higher parity, from about 1.8 times after one pregnancy to nearly 5 times after six or more, compared with women who had not been pregnant. Your individual risk also depends on factors such as family history and other health factors.
Do varicose veins go away after birth?
Pregnancy-related vein changes often improve after birth as blood volume and pressure from the uterus return toward pre-pregnancy levels. Most pregnancy-related vein changes improve within about 3 to 4 months after birth. Some varicose veins may remain, so speak with your healthcare professional if they persist, are painful or concern you.
Why might varicose veins show up earlier in a second pregnancy?
Your veins have already been through the hormonal and circulatory changes of pregnancy once before. When those changes return, along with increasing blood volume and pressure from the growing uterus, previously stretched veins or less efficient valves may become noticeable sooner. Research also shows that risk increases with pregnancy history.
Can compression help with varicose veins during pregnancy?
Compression hosiery may be offered during pregnancy to help relieve varicose-vein symptoms, and graduated compression can support circulation and help manage swelling. Fit and compression level matter, so ask your healthcare professional if you are unsure what is suitable for you.
