Why Pregnancy Causes Swollen Feet and How to Cope
Pregnancy can make a person’s feet and ankles look swollen.
This happens because the body keeps extra blood and fluid while supporting the growing baby.
Pregnancy hormones also relax blood vessels.
As the uterus grows, it can make it harder for blood to travel back up from the legs.
Because of this, some fluid collects in the feet and ankles.
The swelling can become more noticeable later in the day.
It is often temporary, but it may feel uncomfortable.
Dr Kunal Sood shared information about why this happens and ways to improve comfort.
Swelling in the feet and ankles is common during pregnancy, particularly later on.
The body retains more blood and fluid to support the pregnancy.
Pregnancy hormones relax blood vessels, contributing to fluid buildup.
The growing uterus can slow blood returning from the legs, causing fluid to pool.
Swelling is often temporary, may worsen by the end of the day, and can be uncomfortable.
