In addition, pressure in the veins that carry blood back to the heart from the feet causes swollen legs.
This happens because the uterus enlarges, putting pressure on the veins, which can cause fluid retention. Such fluid retention is called "oedema."
It mostly happens in the second and third trimesters of pregnancy.
In addition, this swelling becomes more noticeable in the late afternoon or evening, especially after being on your feet most of the day or during hot weather.

FAQs on Fluid Retention During Pregnancy: What's Normal and What's Not?
- Is swelling more common in the third trimester?
Yes. Swelling usually becomes more noticeable during the third trimester because your uterus is larger and puts more pressure on the veins in your pelvis and legs. - Does drinking more water reduce fluid retention during pregnancy?
Yes. Drinking enough water supports your body's normal fluid balance and healthy circulation, but it may not prevent swelling completely. - Can pregnancy swelling disappear after delivery?
Yes. In most cases, fluid retention improves within a few days after childbirth as your body gradually removes the extra fluid through urine and sweating.
