Diastasis Recti in Pregnancy-Can You Prevent It?

I often get asked if you can prevent diastasis recti in pregnancy. Diastasis recti is a trendy topic with a lot of noise out there online and in the pre- and postnatal space regarding DR, what to do or what to avoid, and magical programs that will heal it. It can certainly feel overwhelming and many women are left feeling like they are broken when they do have it.


Let’s dive into what it is and facts about what you CAN do about it during pregnancy.



So, what is diastasis recti?

It is the thinning out and separation of the left and right sides of the rectus abdominal muscles (the “6 pack” abs) at the linea alba (the connective tissue that runs down the midline of the abdomen).

IT IS NOT THE ABDOMINAL MUSCLES TEARING OR RIPPING APART (unless there is a hernia there, there is no physical tearing, but it is commonly believed to be because of all of the fear-mongering around DR).


A true DR is any separation greater than 2cm, but just because there is a gap, it doesn’t mean that the tissue/muscle there isn’t functional.


Even though diastasis is characterized by the degree of separation, there are many other factors that give us information about your abdominal wall.

Functionality of the tissue at the linea alba with different movements and strategies can give us a better idea of how it works and if there’s anything to be concerned about. How much tension can be generated while doing various movements, how much the rectus abdominal muscles approximate with movement, etc. are ways we can look at functionality.

Diastasis Recti in Pregnancy

The following stats show just how common it is in pregnancy:

-27% of women have DR in the second trimester

-66% in the third trimester (Boissonnault & Blaschak 1988)

-100% by the 35th week of pregnancy (Moth Et al 2015)


In pregnancy, the fascia of the abdominal wall spreads out to accommodate your growing baby and pressure on the core system-this is a GOOD & VERY NORMAL PART OF PREGNANCY! We need to be able to make room for a growing baby and this is how our bodies do it.


Genetics play a role in this as well. Some women have a genetic predisposition to have some degree of a separation at the linea alba, even prior to pregnancy.

Women with shorter torsos may also develop a greater separation during pregnancy because there isn’t a whole lot of room vertically for the belly to grow, so it grows outwards, thus putting more stress on the linea alba.



Should you check for DR in pregnancy?

Unless there are other issues arising (potential hernia, etc.), I do not check my pregnant clients for DR and I don’t think it is necessary to do so. Again, it is a natural part of pregnancy, so I don’t think it’s appropriate to stress a lot about the parts we can’t control. Instead, we are mindful and bring awareness to their movement and strategies to control what we can.




Considerations and things to watch for in pregnancy:

  • Coning or doming along the midline of the abdomen

  • Pulling sensations or pain/sensitivity in the abdomen

  • ANY amount of unintentional leaking (urine or feces)

  • Pelvic pain or pressure, or other pelvic health symptoms

  • Orthopedic pain (hips, back, etc.)
