Why Does Your Belly Button Pop Out When You’re Pregnant?

Though pregnancy is the most beautiful and miraculous phase of a woman’s life, several changes have to be faced by their body. Among the observable changes during pregnancy, the sudden evolution of a protruding belly button, which is popularly known as an ‘outie,’ has been noticed in most women. To some women, this phenomenon may appear very strange, sometimes even causing discomfort. But this is absolutely normal. Now, why does the belly button pop out during pregnancy? We shall try to discuss scientifically, as is possible, reasons underlying this transformation in this paper.

To understand why the belly button pops out during pregnancy, we must first understand the anatomy of the abdominal area. The belly button, also known as the umbilicus, is a scar left behind after the umbilical cord is cut at birth. This cord is responsible for connecting the developing fetus to the placenta, which provides nourishment and oxygen during pregnancy. The umbilical cord contains a vein that carries oxygen-rich blood from the placenta to the developing baby and two arteries that carry deoxygenated blood back to the placenta.

During the second trimester of pregnancy, as the baby grows and the uterus expands, the pressure inside the abdominal cavity increases. This pressure causes the abdominal muscles to stretch and separate, making room for the growing baby. As a result, the uterus pushes against the abdominal wall, causing the belly button to protrude outward. This process is entirely natural and happens to every pregnant woman to varying degrees.

Another factor that contributes to the belly button popping out is the increase in the volume of blood during pregnancy. The body produces around 50% more blood during pregnancy, which helps in delivering oxygen and nutrients to the developing baby. This extra blood volume causes the veins in the abdominal area to dilate, including the ones around the belly button. As a result, the belly button may appear larger and more prominent, giving it an ‘outie’ appearance.

Apart from the physical changes, hormonal changes during pregnancy can also play a role in the transformation of the belly button. The hormone relaxin, which is produced by the ovaries and placenta, softens the ligaments in the pelvic area to prepare for childbirth. This hormone can also affect other ligaments in the body, including those in the abdominal area, making them more pliable. As a result, the belly button may become more flexible and protrude outward due to the increased pressure from the growing uterus.

It is worth noting that not all women experience the belly button popping out during pregnancy. Some women may have a pre-existing ‘outie’ belly button, while others may have a naturally deep and inward belly button. In such cases, the belly button may not pop out as much, or it may stay in its original position throughout the pregnancy.

Cleanliness and Care of the Protruding Belly Button

Although a protruding belly button during pregnancy does not inherently pose any health risks, it is crucial for pregnant women to maintain cleanliness and proper care of the area to prevent potential infections. The skin in the belly button region may become more susceptible to bacterial and fungal growth due to hormonal changes and increased moisture caused by sweating. Pregnant women should follow these guidelines for optimal cleanliness and care:

1. Regularly cleanse the belly button area with warm water and mild soap during showering or bathing. Ensure that the soap is thoroughly rinsed off to prevent skin irritation.
2. Dry the belly button region completely after cleansing to minimize moisture accumulation, which could encourage bacterial and fungal growth. A soft towel or a hairdryer on the low heat setting can be used for drying.
3. Periodically inspect the belly button for signs of infection, such as redness, itching, swelling, or discharge. If any of these symptoms are present, consult a healthcare professional for further evaluation and treatment.

Clothing Choices and Comfort

Selecting the right clothing during pregnancy can play a significant role in enhancing comfort and minimizing discomfort related to a protruding belly button. Tight clothing, particularly those that put direct pressure on the belly button, can lead to irritation, discomfort, and even pain. Pregnant women are advised to consider the following clothing choices:

1. Loose-fitting garments: Opt for clothing that offers ample room for the growing belly, such as flowy dresses or tunics, maternity tops, and stretchy pants with elastic waistbands. This type of clothing can alleviate pressure on the belly button and prevent discomfort.
2. Belly bands or support garments: These products can provide additional support to the abdominal muscles and reduce pressure on the belly button. They can be particularly helpful during physical activities or towards the end of pregnancy when the belly is at its largest.
3. Maternity bras: Investing in well-fitting, supportive maternity bras can help manage breast discomfort and minimize strain on the upper back and shoulders. Look for bras with wide straps, adjustable hooks, and a comfortable band that offers sufficient support.
4. Fabric choices: Select clothing made from breathable, natural fabrics such as cotton, bamboo, or linen, which can help absorb moisture and prevent skin irritation. Synthetic materials such as polyester or nylon can trap heat and moisture, increasing the risk of skin infections and discomfort.

This means, in a nutshell, the popping out of bellybuttons during pregnancy is propelled by factors such as increased abdominal pressure, increase in blood volume, and change in hormonal levels. Actually, this transformation is normal and will go back to its natural form after giving birth. So, women in pregnancy should embrace their ‘outie’ belly button as beautiful and special parts in the journey of their pregnancies.
