During pregnancy, the body experiences various transformations including weight gain and expansion of the uterus as the fetus develops within the womb (2). As a result, pressure is exerted on the abdominal wall, and the surrounding muscles of the stomach are stretched. Moreover, fluid retention occurs, and amniotic fluid accumulates, leading to the uterus pushing against the belly button, As a result, your pregnant belly button starts protruding outwards or turns into an outie.

It is a very normal occurrence during pregnancy, and you need not fret. According to Michael Bermant, M.D. of Bermant Plastic Surgery, your belly button will go back to its original shape in a few months after you are through with your pregnancy.

How To Prevent An Outie Belly Button When Pregnant?

While you are pregnant, you cannot prevent your stomach from growing, and similarly, you cannot prevent your belly button from protruding outwards and becoming an outie. Some people have an inward shaped belly button while some have an outward-shaped belly button even before pregnancy. The original shape of your belly button will not decide whether or not or how much it will protrude while you are pregnant.

Your gynecologists and plastic surgeon will be the best people to guide you about it.

Frequently Asked Questions

1. Does it hurt if my belly button pops out during pregnancy?

During pregnancy, belly button pops are usually painless. However, the outward belly button can rub on your maternity clothes and cause minor discomfort or pain. So, if you have an outie while pregnant, try to cover it with a bandage or wear loose, long dresses to avoid friction (2).

2. Can an outie become an innie during pregnancy?

No. While an ‘innie’ belly button can become an ‘outie’ during pregnancy due to extra pressure on the abdominal walls caused by the growing uterus (2), an ‘outie’ cannot naturally become an ‘innie’ during pregnancy. However, a procedure known as umbilicoplasty can transform an outie into an innie (3).

3. Is the mother’s belly button connected to the baby?

The mother’s belly button is not connected to the baby or any other organ within the body. Therefore, the function of a belly button is vital only in the fetal stage and not beyond birth (4).

4. When does the baby move closer to the belly button?

The baby’s movement is felt above the belly button beyond 24 weeks when the top of the uterus is positioned at the belly button. A kick closer to the rib cage indicates that the baby’s head has aligned with the cervix, which usually happens after 37 weeks (5).

As the child grows in the uterus and the amniotic fluid builds up, the belly button protrudes along with the stomach. As a result, most women experience an outie belly button during pregnancy. After the pregnancy, the belly button generally returns to its original shape, but sometimes, it remains protruded. In this case, you will need a plastic surgeon’s help to bring the belly button back to its original shape. Another reason the belly button may stay protruded is an umbilical hernia. If you notice any discoloration around your belly button, you should contact a doctor. Moreover, remember that changes in the belly button’s shape are a normal part of pregnancy. So do not worry about it, and enjoy your motherhood.
