According to podiatrist Mark Mendeszoon, DPM, it depends on the person and their individual circumstances. "Generally, after the first trimester, feet can really start to change and usually become swollen with fluid," he says. "Then as pregnancy continues to progress, structures can change in which the feet change in shape and size." Overall, swelling in the feet during pregnancy is perfectly normal, but it's important to monitor the situation and talk to your healthcare provider if there's been a sudden change in the situation, or if you’re just worried and would like some peace of mind.
