Pregnancy belly button

Q: Why does an innie navel pop out when a woman is pregnant but not if she just gains a lot of weight?

A: The growing fetus, uterus, and buildup of amniotic fluids cause the abdomen to expand rapidly during pregnancy. So much pressure so fast stretches the skin and ultimately turns an “innie” navel into an "outie." During normal weight gain, the stretching is much more gradual, so there’s no intense, outward push on the abdomen. If your transformed belly button alarms you, don’t worry: It should become an innie again in a few months postdelivery. On the off-chance that it doesn’t (this happens infrequently), minor plastic surgery could restore innie status.
