Pregnancy brings many physical changes, and one of the most common concerns among expectant mothers is swelling, medically known as edema. While swelling is often harmless, certain signs should never be ignored.
Dr. Mini Salunkhe, Director of Obstetrics and Gynecology at Momstory by Sahyadri Hospitals, Hadapsar, explains why swelling occurs during pregnancy, how to differentiate normal swelling from concerning symptoms, and when you should consult a doctor.
What Is Swelling (Edema) in Pregnancy?
Swelling during pregnancy usually affects the feet, ankles, legs, and calves. It happens due to a combination of mechanical, hormonal, and lifestyle-related factors and is especially common in the later months of pregnancy.
Most pregnant women experience some degree of swelling, particularly in the third trimester, and in many cases, it is completely normal.
Why Does Swelling Occur During Pregnancy?
1. Pressure from the Growing Uterus
As the uterus grows, it puts pressure on major veins, especially the inferior vena cava, which carries blood from the legs back to the heart. This pressure slows blood return, causing fluid to accumulate in the lower limbs.
2. Hormonal Changes
Pregnancy hormones such as progesterone and relaxin relax blood vessel walls. This relaxation allows fluid to leak into surrounding tissues, leading to swelling.
3. Lifestyle Factors
Modern pregnancy lifestyles also contribute:
-
Prolonged sitting or standing (10–12 hours)
-
Excess salt and junk food intake
-
Tight clothing or footwear
-
Physical inactivity
These factors are commonly seen in working women and can worsen swelling.
What Is Normal Swelling in Pregnancy?
Normal or physiological swelling:
-
Develops gradually
-
Is more noticeable in the evening
-
Occurs in both legs
-
Reduces after leg elevation
-
Disappears or significantly reduces by morning
This type of swelling is usually due to water retention and is most commonly seen in the last month of pregnancy.
As a best gynecologist in Pune, Dr. Mini Salunkhe reassures that such swelling is generally harmless and manageable with simple lifestyle measures.
When Is Swelling a Cause for Concern?
Certain types of swelling require immediate medical attention. Consult a doctor if you notice:
Sudden or Rapid Swelling
-
Sudden swelling of the face, hands, or legs
-
Rapid increase in swelling over a short time
This may be associated with high blood pressure or pregnancy-induced hypertension.
Swelling in One Leg Only
-
Pain, warmth, redness in one leg or calf
-
Possible sign of deep vein thrombosis (DVT)
This condition requires urgent medical care.
Swelling with Other Warning Symptoms
-
High blood pressure
-
Protein in urine
-
Severe headache
-

These may indicate severe preeclampsia, a serious pregnancy complication.
Medical Conditions That Can Worsen Swelling
Some pregnancy-related conditions can increase edema:
-
Gestational hypertension
-
Gestational diabetes
-
Gestational hypothyroidism
-
Blood clotting disorders
Regular antenatal check-ups with a top gynecologist in Pune help detect these conditions early.
