Diastasis Rectus Abdominis

Her doctor explains to her that there are two large muscle bands that run vertically down the front of a person's abdomen, called the rectus abdominis. During pregnancy, the growing uterus can often cause these muscles to stretch and separate in the center. Kate finds out she has diastasis rectus abdominis, also called diastasis recti.

Abdominal Muscles

Typically, diastasis recti develop later during a woman's pregnancy, and the muscles can remain separated for up to one year after giving birth. Some women may always have a slight separation in their abdominal wall after pregnancy.

Diastasis recti does not only develop in pregnant women. It can also occur in premature infants and men who have experienced excessive weight gain causing the muscles to separate. However, this lesson focuses primarily on diastasis recti in pregnant and postpartum women.

Doctors generally agree that there is no real way to determine who might develop diastasis recti. However, there are certain conditions that might make individuals more likely to develop it. These include pregnant women over the age of 35, women who are pregnant with multiple babies, women who have given birth previously, or babies who have high birth weights.


Symptoms of diastasis recti include:

  • Bump or ridge extending down the middle of the abdomen
  • Extra skin or tissue noticed in the front of the abdominal wall
  • Lower back pain
  • Pelvic floor problems, such as urine leakage
  • Constipation
  • Hernia: when abdominal tissue or another organ pushes through the hole in the abdominal wall.

Diastasis Rectus Abdominis: A Case Study

In this activity, you'll check your knowledge regarding the symptoms and treatment of diastasis rectus abdominis.


For this activity, print or copy this page on a blank piece of paper. Then, carefully read the given scenario and provide a written response to the questions that follow.


Jesse is 36 weeks pregnant with her second child. To prepare for her pregnancy, she spent most of her time doing clinical pilates exercises. Jesse had found it useful in maintaining strength and muscle control of the pelvic region, which she learned from her previous pregnancy. Unfortunately, she gave birth too early, right before she got to the 37th week. Her baby had complications, including abdominal ridge, constipation, and urine leakage. Upon physical examination, the attending physician found out that the bloated abdomen was due to an extra tissue, which pushes the hole in the abdominal wall.


  1. What are the most striking clinical findings for Jesse's newborn?
  2. Does the baby have diastasis recti? Why do you say so?
  3. Enumerate the individuals that are susceptible to diastasis recti.
  4. From the physical exam result, is it true that the baby also has a hernia? Prove your answer.
  5. What type of medical treatment must be administered to the patient?

Sample Answers

  1. The complications due to being born prematurely, such as an abdominal ridge, constipation, and urine leakage, are the most striking clinical findings.
  2. Yes. The symptoms exhibited by the newborn are all indications of diastasis recti.
  3. Invididuals susceptible to diastasis recti are pregnant women over the age of 35, pregnant women with multiple babies, women who have just given birth, and babies born with complications.
  4. Yes. The baby had tissue pushing through the hole in the abdominal wall, which is indicative of a hernia.
  5. For cases involving a hernia, physicians usually recommend surgery to fix the abdominal wall opening.
