Varicose Veins During Pregnancy — Risks, Symptoms and Safe Treatment

Pregnancy is one of the most common triggers for varicose veins. Understanding why they develop and when to seek treatment can save significant discomfort — and prevent serious complications.

Why Pregnancy Causes Varicose Veins

Three mechanisms combine during pregnancy to cause varicose veins:

1. Increased blood volume: Blood volume increases by 40–50% during pregnancy, putting much more pressure on leg veins.
2. Hormonal changes: Progesterone relaxes smooth muscle in vein walls, causing them to stretch and the valves to become less competent.
3. Uterine pressure: The growing uterus compresses the inferior vena cava (the main vein returning blood from the legs), increasing backpressure in leg veins.

Varicose veins typically appear or worsen in the first trimester and may progress through pregnancy.

Are They Dangerous During Pregnancy?

In the vast majority of cases, pregnancy-related varicose veins are uncomfortable but not dangerous. The main risk to monitor for is superficial thrombophlebitis (a blood clot in the varicose vein itself) — which causes acute pain, redness, and hardening of the vein — and the rare but more serious deep vein thrombosis (DVT). Pregnant women with varicose veins should watch for sudden severe calf pain or swelling of the entire leg and seek immediate care if these occur.

What Can You Do During Pregnancy?

Active treatment (RF Ablation) is generally deferred until after delivery. During pregnancy:

• Wear Class 2 graduated compression stockings from the morning
• Elevate your legs whenever possible — prop your feet up at 30 degrees
• Sleep on your left side to reduce pressure on the inferior vena cava
• Take short walks every hour — muscle activity pumps blood upward
• Avoid prolonged standing

Do Varicose Veins Go Away After Delivery?

Many women see significant improvement within 3–6 months of delivery. However, some veins — particularly those that were present before pregnancy or that were severe — do not fully regress. Each subsequent pregnancy tends to worsen existing varicose veins.

When to Treat After Delivery

If varicose veins persist or remain symptomatic 3–6 months after delivery, assessment and treatment are recommended. RF Ablation is safe during breastfeeding (local anaesthesia only, no general anaesthesia or systemic drugs).
