Diastasis recti is a condition where the rectus abdominis muscles (colloquially known as six-pack abs) separate during pregnancy due to the stretching of the abdominal wall to accommodate a growing baby. This separation can cause a gap in the abdomen, resulting in a bulge or pooch that may persist for months or years after childbirth. While it is a common condition affecting many postpartum women, it can also occur in men and infants. Treatment options include specific exercises, physiotherapy, and in severe cases, surgery.

What You'll Learn

Diastasis recti is common in postpartum women
Diastasis recti is a condition that occurs when the left and right abdominal muscles separate during pregnancy, creating a gap in the abdomen. This gap can make the belly bulge or pooch after childbirth, a common symptom of the condition. Diastasis recti is very common during and after pregnancy, with one study finding that up to 60% of women may experience it during these periods.
The condition develops due to the stretching of the abdominal muscles and connective tissues as the uterus expands to accommodate the growing baby. Pregnancy hormones like relaxin and estrogen also contribute to this process. Pushing during delivery can further increase the likelihood of diastasis recti. While it usually occurs during pregnancy, it may only be noticed several weeks after giving birth.
Diastasis recti can cause emotional and physical frustration. It may lead to self-consciousness due to the visible belly bulge and can also result in lower back pain from weakened abdominal muscles. However, it is important to note that the condition is typically painless. Experiencing some abdominal separation during and after pregnancy is expected, and it often resolves on its own as the muscles regain strength.
Postpartum treatment for diastasis recti typically involves specific exercises that target the pelvic floor and deep stomach muscles. These exercises help close the separation and rebuild core strength. It is important to consult a doctor before starting any exercise program to ensure a safe and effective approach to healing.
Additionally, there are preventive measures that can be taken to lower the risk of developing diastasis recti during pregnancy. Maintaining a healthy weight gain, practising good posture, and performing safe core exercises can help reduce the likelihood of experiencing this condition.

It is caused by the stretching of the rectus abdominis muscles
Diastasis recti is a condition characterised by the stretching and separation of the rectus abdominis muscles, also known as "six-pack abs". This condition commonly occurs during pregnancy due to the expansion of the uterus, which stretches the muscles in the abdomen to accommodate the growing baby. It is important to note that diastasis recti is not limited to pregnancy and can also occur in newborn babies, men, and individuals who engage in heavy weight lifting or excessive abdominal exercises.
The rectus abdominis muscles are a pair of muscles that run vertically along the front of the stomach. During pregnancy, the band of tissue called the linea alba that divides the rectus abdominis muscles can thin and pull apart. If this band of tissue loses its elasticity from excessive stretching, it may not fully retract, resulting in a persistent gap between the left and right abdominal muscles. This separation can cause the belly to stick out or bulge, a common symptom of diastasis recti.
The severity of diastasis recti can vary, and it may not always present noticeable symptoms during pregnancy. However, in some cases, a bulge or ridge may develop on the belly, particularly when straining or contracting the abdominal muscles. This condition can also lead to functional and cosmetic issues, including lower back pain, pelvic instability, and negative body image.
To diagnose diastasis recti, a simple self-test can be performed. An individual can lie on their back with bent knees and feet flat on the floor. By lifting the upper body slightly and gently pushing down on the centre of the stomach, a gap between the abdominal muscles may be felt. If the gap is more than two finger widths, it indicates a likely case of diastasis recti.
Treatment options for diastasis recti include specific exercise programs targeted at strengthening the abdominal muscles and closing the gap. Physiotherapy and, in severe cases, surgery may also be considered. However, it is important to consult with a healthcare professional to determine the most appropriate treatment plan.

It can be healed with specific exercises
Diastasis recti is a condition that occurs when the left and right abdominal muscles, also known as the rectus abdominis muscles, separate during pregnancy. This separation can cause the belly to bulge or pooch after childbirth, affecting 6 in 10 women. It is characterised by thinning and widening of the linea alba, a band of tissue that divides the rectus abdominis muscles, with concomitant laxity of the ventral abdominal wall muscles.
Diastasis recti can be healed with specific exercises that help close the separation between the abdominal muscles. It is important to focus on contracting the abdominal muscles, which means drawing the belly button towards the spine to increase stability and reduce pressure on the rectus abdominis. This abdominal contraction can be incorporated into daily activities such as squatting or walking, by holding the contraction for up to a minute. Additionally, exercises such as the alternating toe touch can be performed by lying on the back with the legs up and reaching the hands towards the toes, lifting the shoulders to target the rectus abdominis and oblique muscles.
There are also specific exercise programs targeted at diastasis recti, such as the 12-week Every Mother program, which employs an abdominal draw-in manoeuvre. This involves participants pulling their belly button towards their back while in different body positions. These exercises have been shown to reduce the distance between the rectus abdominis muscles and improve related symptoms such as urinary incontinence and low back pain.
It is important to note that healing diastasis recti is not just about knowing what exercises to do but also about avoiding certain activities that can exacerbate the condition. Everyday activities that increase pressure on the core, such as bearing down during a bowel movement or holding your breath while lifting something heavy, can make the abdominal separation worse. Therefore, it is crucial to focus on contracting the abdominal muscles and avoiding activities that strain the core.
Overall, diastasis recti can be effectively managed and improved with specific exercises that target the abdominal muscles and reduce the separation between them. These exercises can help improve both the cosmetic and functional issues associated with diastasis recti, promoting healing and reducing any discomfort caused by the condition.

Diastasis recti is often mistaken for an abdominal hernia
Diastasis recti is a condition where the left and right rectus abdominis muscles, commonly known as "six-pack abs", separate. This separation can cause the abdomen to bulge or pooch, which may lead to mistaking the condition for an abdominal hernia.
Diastasis recti is often associated with pregnancy, particularly in the third trimester, due to the expansion of the uterus and the thinning of the linea alba, a band of tissue that divides the rectus abdominis muscles. The condition can also be congenital or develop in the womb, and it is commonly seen in newborns, especially premature and African American infants.
An abdominal hernia occurs when there is a hole in the tissues of the belly wall, allowing fat, fluid, or an organ to protrude. Hernias typically cause substantial pain and can be located near the belly button, in the groin, or at a previous surgical incision. They may enlarge over time if left untreated, leading to life-threatening complications such as strangulation, where the blood supply to the intestine is cut off.
Diastasis recti, on the other hand, is not a hernia and does not carry the same medical risks. While it can cause discomfort and abdominal wall weakness, it does not have the risk of strangulation or bowel ischemia. The distinction between the two conditions is the presence of a true hernia sac in a hernia, which is absent in diastasis recti.
The confusion between diastasis recti and a hernia arises from the similar presentation of a bulge in the abdomen. However, it is important to note that diastasis recti is characterized by the thinning and widening of the linea alba, resulting in laxity of the abdominal wall muscles. Treatment options for diastasis recti include conservative management, exercise, and, in severe cases, surgery.

It can also occur in infants and men
Diastasis recti is a condition characterised by the abnormal thinning and separation of the rectus abdominis muscles at the midline, often associated with laxity of the abdominal muscles. It is commonly observed in pregnant women due to the stretching of the rectus abdominis muscles by the expanding uterus. However, it can also occur in infants and men, although the presentation and causes may differ.
In infants, diastasis recti is typically a benign condition that often resolves on its own over time. It occurs when the rectus abdominis muscles are not fully developed and may be widely separated in the upper abdomen, creating a broad linea alba that can be relatively thin. This separation can allow a bulge to form between the umbilicus and xiphisternum during straining, but this is usually of no clinical significance. In some cases, surgical intervention may be necessary if the infant develops a hernia that becomes trapped between the muscles.
In men, diastasis recti can occur at any age and is typically associated with increased abdominal pressure. Risk factors include obesity and excessive abdominal exercises. The condition can cause pain and discomfort in the abdomen, as well as musculoskeletal issues such as lower back pain and pelvic instability. Treatment options for men with diastasis recti are similar to those for women, including physiotherapy, abdominal binding, and, in severe cases, surgery.
The diagnosis of diastasis recti in both infants and men can be made through physical examination, which involves measuring the distance between the left and right rectus abdominis muscles. Treatment options are generally conservative, focusing on strengthening the abdominal muscles and improving core stability. However, in cases where the condition causes significant discomfort or functional impairment, surgical procedures such as abdominoplasty may be considered.
It is important to note that diastasis recti is not a pathological entity in itself and does not carry any associated morbidity or mortality. However, it can impact quality of life due to cosmetic concerns and functional limitations. Therefore, treatment options aim to address these issues and improve patients' overall well-being.

Frequently asked questions
Rectus muscle diastasis, also known as diastasis recti, is the partial or complete separation of the rectus abdominis, or "six-pack" muscles, which meet at the midline of the stomach.
Rectus muscle diastasis is commonly caused by pregnancy, as the uterus stretches the abdominal muscles to accommodate the growing baby. It typically develops during the second or third trimester.
The most common symptom is a bulge or pooch in the belly area, especially when straining or contracting the abdominal muscles. It may be noticeable when trying to use the abdominal muscles to stand, sit up, or lie down.
Rectus muscle diastasis can be self-diagnosed by lying on the back with bent knees and feet flat on the floor. While lifting the upper body slightly, use two fingers to gently push down on the stomach above, at, and below the belly button. If you feel a gap of more than two fingers' width between the abdominal muscles, it indicates rectus muscle diastasis.
Treatment options for rectus muscle diastasis include physical therapy, exercise programs targeted at diastasis recti, and in severe cases, surgery. Healing focuses on regaining the ability to contract the abdominal muscles and reducing the distance between the separated muscles.
