Swelling in Feet, Ankles, and Hands During Pregnancy
The short answer
Mild to moderate swelling (edema) in the feet, ankles, and hands is very common in pregnancy, affecting about 80% of pregnant people. It is caused by increased blood volume and fluid retention, and it is usually harmless. However, sudden or severe swelling, especially in the face and hands, can be a warning sign of preeclampsia.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Mild swelling is uncommon in the first trimester. Your body is beginning to increase blood volume, but visible edema usually does not develop this early. If you notice significant swelling in the first trimester, mention it to your provider.
Swelling typically begins in the second trimester as blood volume increases. Your feet and ankles may swell, especially later in the day or in warm weather. Elevating your feet, staying hydrated, reducing sodium intake, and wearing comfortable shoes can help. Rings may start to feel tight on your fingers.
Swelling is most pronounced in the third trimester when blood volume peaks at about 50% above normal. The growing uterus puts pressure on pelvic veins, slowing blood return from the legs. Elevate your legs when possible, sleep on your left side, wear compression stockings, and stay active with gentle walking. Swelling that worsens gradually throughout the day and improves with rest is typically normal.
Swelling may temporarily worsen in the first few days after delivery as your body sheds excess fluid, especially if you received IV fluids during labor. Postpartum swelling usually resolves within 1-2 weeks. Continue to stay hydrated and elevate your legs when resting.
What Should You Do?
When to take action
- Gradual, mild to moderate swelling in feet and ankles that worsens throughout the day
- Swelling improves with rest, elevation, and overnight sleep
- Both feet and ankles are equally affected
- Swelling is worse in warm weather or after prolonged standing
- Swelling does not improve with rest and elevation
- Your hands are noticeably swollen and you cannot remove your rings
- Swelling seems to be increasing more rapidly than expected
- Sudden severe swelling of your face and hands, which can be a sign of preeclampsia
- Swelling in only one leg with pain, warmth, or redness, which could indicate a blood clot
- Severe swelling accompanied by headache, vision changes, or upper abdominal pain

Preeclampsia Warning Signs
Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of organ damage, usually after 20 weeks of pregnancy. It affects about 5-8% of pregnancies and can range from mild to severe. With regular prenatal monitoring, preeclampsia can be detected early and managed to protect both you and your baby.
Blood Clot Risk During Pregnancy (DVT)
Pregnancy increases the risk of blood clots (venous thromboembolism or VTE) by 4-5 times due to increased clotting factors, slower blood flow, and vein compression from the growing uterus. While the overall risk is still low (about 1-2 per 1,000 pregnancies), awareness of symptoms is important because blood clots can be life-threatening if untreated.
Carpal Tunnel Syndrome During Pregnancy
Carpal tunnel syndrome during pregnancy is caused by fluid retention that compresses the median nerve in the wrist, leading to numbness, tingling, and pain in the hands and fingers. It affects up to 60% of pregnant people, is most common in the third trimester, and usually resolves after delivery.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
