Weeks 20-40

Swelling / Edema

Last reviewed by medical team: June 2026

🔵 Common Pregnancy Symptom

Why It Happens

Your body produces about 50% more blood and body fluids during pregnancy. Extra water retention and pressure from the growing uterus on veins cause swelling in the ankles, feet, and hands.

Safe Home Remedies

Elevate your feet above heart level when sitting.
Drink plenty of water to help flush out fluids.
Avoid standing or sitting in one position for long periods.
Wear compression socks.

⚠️ When to Contact a Doctor

Contact your doctor immediately if you experience sudden swelling in your face or around your eyes, or if one leg is significantly more swollen than the other (which can indicate a blood clot).
