Why do your feet get bigger when pregnant?
As strange as it may seem, it’s not just your belly that can grow during pregnancy. So can your feet!
During pregnancy, your feet may increase in size (and even width) due to elevated levels of the hormone relaxin. This hormone loosens ligaments and joints to prepare for childbirth, including those in the feet. Another reason your feet can get bigger is that as the baby grows and develops, excess weight is placed upon the feet and your body is more susceptible to retaining fluids.
Is it permanent?
A study published by the American Journal of Physical Medicine and Rehabilitation suggests that your new shoe size may be permanent. The authors of this study concluded, “Pregnancy seems to be associated with a permanent loss of arch height, and the first pregnancy may be the most significant.” They also note that “these changes in the feet could contribute to the increased risk for musculoskeletal disorders.” With this in mind, be sure to purchase shoes that fit well and provide adequate support during pregnancy and in the years to come.
Can I prevent it?
Pregnancy triggers a multitude of transformative changes, and some can’t be prevented. You can prevent your feet from getting bigger during pregnancy, you could take proactive measures to address swelling and weight gain.
Wearing compression socks can reduce swelling, and supportive shoes and insoles can support the ligaments and joints in your feet. Also, try to stay within the recommended weight gain range for your body type; this will reduce excess pressure on your feet, especially during the third trimester. Foot muscle exercises could also improve blood circulation in your feet and reduce swelling. Whether any of these strategies will work for you depends on individual factors, including pregnancy-related hormones.
Even if your feet grow during pregnancy, take it as a sign that your body is undergoing natural changes meant to support your baby's healthy growth and development. As your body adapts, your shoe size might need to adapt, too.
