Pregnancy brings numerous bodily transformations as it adapts to support a developing baby. Among these, the belly button often undergoes a noticeable shift, reflecting dynamic adjustments within the abdominal region.
The Timing and Cause of Your Belly Button Changing
The appearance of your belly button changes around the end of the second trimester, or the beginning of the third trimester, around 26 weeks into pregnancy. This transformation occurs as the growing uterus expands significantly, pushing against the abdominal wall. The increased internal pressure causes the navel to flatten or even protrude outward, turning an “innie” into an “outie” for some individuals.
This outward shift stretches the linea alba, a fibrous band of connective tissue running down the center of the abdomen. Not all pregnant individuals experience their belly button “popping out,” as the extent of the change varies based on individual anatomy and how the pregnancy is carried. For those who had an “innie” before pregnancy, it might flatten or become an “outie,” while an existing “outie” may become more prominent.
Normal Changes and When to Consult a Doctor
The skin around the navel may appear stretched, smooth, or discolored, sometimes accompanied by the development of a dark vertical line called the linea nigra. Common sensations include itchiness, sensitivity, or mild stretching discomfort, which can be due to the skin expanding or friction from clothing. Applying a gentle, fragrance-free moisturizer can help alleviate dryness and irritation. Wearing loose, comfortable clothing may also reduce friction and discomfort.
While most belly button changes are harmless, consult a healthcare provider if you experience severe or sharp pain, redness, swelling, or discharge from the navel area. A persistent, painful bulge around the belly button, especially if it worsens with coughing or straining, could indicate an umbilical hernia, where a part of the intestine pushes through a weakened abdominal wall. Although umbilical hernias are often benign during pregnancy, a medical professional can assess the situation and recommend appropriate management.
What Happens After Delivery
Following childbirth, the belly button typically returns to its pre-pregnancy appearance. This process occurs as the uterus shrinks back to its original size and the abdominal muscles regain their tone. The timeline for this regression varies among individuals, usually taking several weeks to months postpartum.
While most belly buttons will revert to an “innie,” the navel may not look exactly as it did before pregnancy. Some individuals might notice slightly looser skin around the area, a subtle change in shape, or a less firm appearance. These minor alterations are considered normal outcomes of the significant bodily changes experienced during pregnancy.
