What’s A B Belly? Let’s Talk About It!

What is a B belly during pregnancy?

A B belly during pregnancy is one that seems to have a crease or band in the centre, dividing the belly into a top and bottom half, similar to the capital letter “B.” It’s important to notice that your bigger pregnant breasts aren’t at the top of the B! If this were true, practically every woman would be pregnant with a B belly. A B belly form is distinct from the more typical D belly shape, which looks like a capital letter “D” and lacks a separating feature. The B belly is also referred to as a double belly pregnancy.

What Are the Causes of a Plus Size Pregnancy Belly?

There is no one cause of B belly during pregnancy. However, characteristics like weight, bone structure, muscle, and height all contribute to the method and manner in which a pregnant bump is carried. B belly is most common in plus-size women.

Having said that, a big size pregnant belly might be caused by any of the following factors:

1. Body Weight and Size

According to the Centers for Disease Control and Prevention (CDC), a woman with a Body Mass Index (BMI) of 30 has an obese pregnant belly, whereas a woman with a BMI of 25 – 29.9 has an overweight pregnant belly.So, a woman who is heavier at the start of her pregnancy is more likely to have a B belly – though this is not a guarantee!

2. Previous Pregnancy

After their first pregnancy, some women’s abdominal muscles become lax, and their form increases more swiftly when they get pregnant again. B belly may arise when the body has not completely recovered from the previous pregnancy or when the following pregnancy is too near.

3. Natural Belly Shape

Women whose weight is concentrated in their belly – as opposed to their thighs or hips – prior to becoming pregnant are more likely to develop a plus size pregnancy belly bump, even if it is their first pregnancy. Another factor that may contribute to a B-shaped stomach during pregnancy is an apron belly, which occurs when the lower area of the stomach hangs down.

4. Facial Well-being

The fascia is the connective tissue under the skin that shapes the belly during pregnancy. However, the fascia may have been damaged, which could have occurred as a result of eating an unbalanced diet, injured muscles, poor posture, dehydration, or stress. Furthermore, the fascia may have been influenced by the anatomy of your stomach or previous pregnancies. So, to get the most out of fascia, make sure to drink plenty of water, stretch frequently, and do some yoga during your pregnancy.

5. Recti Diastasis

This may also alter the appearance of your stomach. Diastasis recti is caused by an increase in intra abdominal pressure. The abdomen expands during pregnancy, and the tissues stretch as a result of the foetus. As a result, the belly stretches, and the gap between the right and left stomach muscles widens. This is a frequent occurrence throughout pregnancy; however, for some women, it will resolve itself after birth when the abdominal muscle regains power.

Are there any problems concerning a B belly?

Your doctor should not be alarmed if you have a B belly. However, if weight is one of the factors causing the shape, your practitioner may want to discuss additional health concerns.

Concerns about health

Those who are overweight are more likely to suffer from:

Diabetes during pregnancy. Not only can gestational diabetes increase the likelihood of caesarean delivery, but it may also need to be controlled during pregnancy through diet or medication. Preeclampsia, often known as high blood pressure. This can cause swelling and harm to vital organs such as the liver and kidneys.

Backache during pregnancy

The baby of a woman with a higher BMI is also at a higher risk for certain complications, such as:

Larger size during birth, which may result in damage or complications during delivery.

Premature birth, which may result in issues with organs such as the heart, lungs, brain, and gastrointestinal system.Because there are added pregnancy dangers if a woman is either overweight or underweight, it’s critical that weight gain be monitored and spaced out during the length of your pregnancy.

According to the Centers for Disease Control and Prevention, a woman who is overweight should aim to gain 15 to 25 pounds if she is having a single child. A pregnant lady with obesity should try to gain 11 to 20 pounds throughout her pregnancy. What would this look like during the duration of a pregnancy? You should gain 2 to 4 pounds throughout the first trimester. Following that, gaining roughly half a pound every week for the rest of the pregnancy is a healthy target.

Emotional issues

There may also be emotional difficulties associated with having a different belly shape than planned during pregnancy. This may happen to anybody, no matter what their belly shape or size is. Whatever you’re feeling, know that it’s normal to experience a wide variety of emotions, and you’re not alone! If people make insensitive remarks about your stomach, you may need to depend on resilience strategies like visualisation and peer support. Understand that every pregnant body is unique, and yours is working hard to nourish and develop your child.


You may have great expectations for the world’s simplest pregnancy, complete with the world’s loveliest baby belly, but reality doesn’t always go as planned! If you have a bump that looks like the letter B, know that you are not alone. Your bump may change form throughout your pregnancy, and even if it doesn’t, it’s not anything you need to be concerned about.

While B belly pregnancies are relatively uncommon, it is always a good idea to discuss your concerns with your doctor.
