Medically reviewed by healthcare professionals | Last reviewed: March 2026
📅 When It Occurs
Usually appears second or third trimester, worsens as pregnancy progresses
📊 How Common
Affects 20-40% of pregnant women
Overview
Varicose veins appear as enlarged, twisted, blue or purple veins visible just under your skin's surface. They most commonly occur in the legs but can also develop in the vulva (vulvar varicosities) during pregnancy.
These occur when valves in your veins weaken or fail, allowing blood to pool and veins to swell. Pregnancy increases risk due to increased blood volume, hormones that relax vein walls, and pressure from your uterus slowing blood return from your legs.
While often just a cosmetic concern, varicose veins can cause aching, heaviness, and discomfort. They often improve after delivery but may not disappear completely, especially with subsequent pregnancies.

🔍 What Causes It?
- •Increased blood volume putting pressure on veins
- •Progesterone hormone relaxing vein walls
- •Growing uterus compressing pelvic veins and impeding blood flow

- •Standing for long periods
💡 Relief Strategies
- ✓Wear graduated compression stockings (20-30 mmHg)
- ✓Elevate legs above heart level whenever possible
- ✓Avoid standing or sitting for extended periods

- ✓Sleep on your left side to take pressure off major vein (inferior vena cava)
- ✓Avoid crossing your legs when sitting
- ✓Maintain healthy weight gain during pregnancy
- ✓Avoid constrictive clothing around waist and legs
- ✓Stay cool - heat makes veins dilate more
