Which Body Parts Will Get Bigger When You're Pregnant?

In addition to a growing belly, your breasts enlarge during pregnancy because of the hormonal production that stimulates the milk producing tissue, notes Dr. Lisa Keder, director of the Division of General OB-GYN at The Ohio State University. Some women may also experience swollen ankles, feet and fingers during pregnancy, as well as weight gain in the arms, buttocks and legs due to fluid retention. Many other physiologic changes in pregnancy, such as cardiovascular, metabolic and respiratory adjustments, affect the body to provide for the fetus, but these changes don’t necessarily make body parts larger, says Keder.
