Varicose veins are common in pregnancy because of increased blood volume, hormonal effects on vein walls, and pressure of the womb on pelvic veins. Many improve within months after birth. Symptoms are eased with compression stockings, leg elevation and walking, and laser or injection treatment is postponed until after delivery. Any sudden painful swelling of one leg needs an urgent Doppler.
Many women notice varicose or spider veins for the first time during pregnancy, or existing veins getting worse. This is common and has clear causes.
Why do varicose veins appear in pregnancy?
- Blood volume rises considerably.
- Progesterone relaxes vein walls.
- Pressure from the womb on large pelvic veins slows blood return from the legs.
- Genetics: a family history increases risk.
- Repeated pregnancies increase the chance.
Vulval varicose veins
Varicose veins can appear in the vulval area during pregnancy and usually improve a lot after birth. If they persist or come with pelvic pain afterwards, the pelvic veins need assessment.
Easing symptoms safely
- Medical compression stockings suitable for pregnancy, after asking your doctor.
- Raise your legs when sitting and resting.
- Walk daily and avoid long periods of standing or sitting still.
- Sleep on your left side in late pregnancy to reduce pressure on the inferior vena cava.
- Avoid clothing that is tight at the waist and thighs.
Do they go away after birth?
Many veins that appeared in pregnancy improve or disappear within the first months after birth, so it is usually advised to wait several months before deciding on treatment. Veins that persist can be treated with laser, radiofrequency or injections, ideally after breastfeeding depending on the treatment.
Can they be treated during pregnancy?
No. Interventional treatment is usually postponed until after delivery; compression and simple measures are used during pregnancy.
When to see a doctor immediately
Pregnancy and the weeks after birth carry a higher risk of deep vein thrombosis. Contact your doctor immediately for:
- Sudden painful swelling of one leg.
- Redness, pain and a hard cord along a vein.
- Shortness of breath or chest pain.
