Post-Baby Belly Bulge – Diastasis Recti or Abdominal Fat?

Do I have torn abdominal muscles (Diastasis Recti) or just a bit of excess tummy fat?

We’re never quite prepared for what pregnancy, childbirth and breastfeeding can do to our bodies. Whilst some people seem to ‘bounce back’ almost effortlessly, the more common scenario most of us face is a very different body shape after pregnancy and breastfeeding. Whilst most of us are programmed to think that tummy bulges mean we need to hit the gym or go on a diet, this may not always be the case. In actual fact, the changes our bodies endure as a result of pregnancy cannot all be remedied by exercise alone; because torn abdominal muscles or excess skin folds cannot be exercised away.

What could be the cause of my excess tummy fat?

Can that bulging tummy or ‘muffin top’ that lingers after childbirth actually be something else? Something that only surgery can fix? Find out if you have torn abs and whether or not a Tummy Tuck procedure to correct your abdominal muscles help.

Can my post-baby tummy bulges be remedied through exercise and nutrition alone? This depends on a number of factors, including:

  • your lifestyle
  • your genetics and body frame
  • how much weight you gained or lost
  • your skin strength
  • the size of the baby or babies you delivered
  • the size of your baby or babies at birth
  • how many times you have given birth

Commonly, excess tummy fat or skin folds are actually a result of damage to your abdominal muscles during pregnancy or childbirth. Having more than one child or a large baby can increase your chance of abdominal muscle damage (known as diastasis recti), although any woman can experience it.

What are torn abdominal muscles (Diastasis Recti)?

torn abdominal muscles during pregnancy

The term ‘diastasis recti’ describes a split between the two sides of the rectus abdominis muscle. Other medical and everyday terms used to describe the post-pregnancy condition of split abdominal muscles include: abdominal separation, torn abdominals or split abs.

We know that Diastasis Recti may also be the reason we have a post-baby tummy bulges that exercise and nutrition alone won’t remedy. Although changes to your diet and exercise regime may help somewhat, often patients require a Tummy Tuck (Abdominoplasty) to repair the damage.

What causes torn Abdominal Muscles and how can it be fixed?

There are a few causes for this condition, although the most common for women is, in fact, pregnancy and childbirth.

Put simply, when the uterus is growing during pregnancy, the abdominal muscles also get stretched. Like the skin, this area tends to get overstretched. Although you can see when your skin is overstretched as stretch marks often develop, you are often not aware this has occurred internally as well.

The stretching of the abdominal area during pregnancy causes the two main panels of muscle down the middle of your abs to separate. This leaves a ‘bulge’, which is a sign of the place where those muscles have separated.

The good news is that diastasis Recti can be fixed. Although if your muscles are actually split to the level where they have left a gap, a rounded tummy and a persistent post-baby belly bulge, this will often involve surgery.

How can you know if you have torn abs or something else?

Torn abdominal muscles are very common; a study shows that a staggering 98% of women have diastasis recti after they have delivered their babies.

If you suspect you have torn abdominal muscles as a result of pregnancy, you can perform an at-home check like the one in this link. Basically, if you can fit 2-3 fingers in between your ab muscles, you likely are suffering from diastasis recti.

Should you be concerned with your at-home test results, or would like a professional opinion, we suggest arranging for a medical consultation. This could either be with a Specialist Plastic Surgeon who performs precision Tummy Tuck surgery and/or ask your GP or obstetrician for a referral.

Do exercises help diastasis recti?

Occasionally for some patients, special exercises can also be utilised to help. But if not performed properly they can make the condition, or the bulge, worse.

There are a number of excellent post-partum workout sites that offer special videos showing exercises to help with tummy recovery.  Some physiotherapists also focus their practices on post-pregnancy exercise recommendations.  Send an enquiry form below for more information on surgery corrections or for other Surgeons or Medical Professionals who might be able to assist you.

What should I avoid if I have split abdominal muscles?

One of the most important things to note is avoiding certain exercises, like crunches, which actually make the problem worse. In fact, many of the Mummy Bloggers suggest avoiding planks, crunches and sit-ups, because these increase abdominal pressure and push outwards through the gap – this is the opposite of what you want!

Best to research the advice of post-partum exercise tips, such as those from the Tummy Team and their resources. But do ask your doctor for advice as this information may not suit your specific condition.

What can be done to correct the condition of diastasis recti?

If you have split your abdominal muscles through pregnancy, the long-term solution is actually Abdominal surgery or a full Abdominoplasty with abdominal muscle repair (such as performed by Specialist Plastic Surgeons who focus on Mummy Makeovers including our Team of Melbourne Plastic Surgeons.

Our custom Tummy Tuck surgeries often include full repair of diastasis recti, repositioning of the navel, and reduction of excess skin and body fat using a combination of surgical techniques and liposuction.
