Parents discusses the causes of swollen feet and ankles, and leg pain during pregnancy according to experts including HSS foot and ankle surgeon David S. Levine, MD.
Raised hormone levels cause women to retain water while expecting, which leads to swelling and bloating (also known as edema). The body needs this extra fluid to carry nutrients and oxygen to your baby, explained Dr. Levine.
