Ab Muscle Separation

Also called: diastasis recti, ab separation, muscle separation, separated abs, ab muscle separation, abdominal muscle separation

Abdominal muscle separation, also known as diastasis recti, occurs when the connective tissue between the abdominal muscles stretches and widens, creating a visible or noticeable gap through the centre of the abdomen. It commonly develops during pregnancy or following significant

TYPICALLY OCCURS

During pregnancy, after childbirth, weight changes, or increased abdominal pressure.

TREATED BY

Abdominoplasty, muscle repair, physiotherapy, and more.

Why it happens?

Abdominal muscle separation, or diastasis recti, develops when the connective tissue running between the two sides of the rectus abdominis muscles becomes stretched and widened. This reduces the tension that normally holds the abdominal muscles close together and can create a visible gap, bulge, or reduced firmness through the centre of the abdomen.

Pregnancy is one of the most common causes, as the growing uterus places increasing pressure on the abdominal wall while hormonal changes allow the connective tissues to stretch. The likelihood may increase with multiple pregnancies, carrying a larger baby, or significant stretching of the abdomen.

Diastasis recti can also occur outside pregnancy. Significant weight changes, obesity, repeated increases in abdominal pressure, and individual differences in connective tissue strength may contribute. In more pronounced cases, the separation can affect abdominal contour and core function, although the severity and symptoms vary considerably from person to person.

How far along is it?

Early

Mild abdominal separation is present, with a small gap between the abdominal muscles and subtle bulging that may be most noticeable during certain movements or when engaging the core.

Moderate

The separation becomes more noticeable, with a wider abdominal gap, increased central bulging, and reduced abdominal wall support or core strength.

Advanced

Pronounced separation creates a wider, more persistent abdominal bulge and may be associated with reduced core stability, abdominal wall weakness, and changes in overall abdominal contour.

It may be worth seeking professional advice when abdominal muscle separation remains noticeable, causes persistent bulging, affects core strength or everyday movement, or does not improve after pregnancy and recovery. A professional assessment can determine the extent of the separation and whether physiotherapy, lifestyle measures, or surgical repair may be appropriate.

Quick Questions:

What causes abdominal muscle separation?

Abdominal muscle separation, or diastasis recti, occurs when the connective tissue between the abdominal muscles stretches and widens. Pregnancy is a common cause, although weight changes and repeated abdominal pressure can also contribute.

How do I know if I have diastasis recti?

Common signs include a visible gap or bulge along the centre of the abdomen, particularly when sitting up, coughing, or engaging the abdominal muscles. A professional assessment can confirm the extent of separation.

Can diastasis recti heal without surgery?

Yes. Some cases can improve with time and targeted physiotherapy or core rehabilitation. However, more significant or persistent separation may not fully resolve without surgical repair.

Can a tummy tuck repair abdominal muscle separation?

A tummy tuck (abdominoplasty) can include repair of the abdominal wall by tightening the tissue around separated rectus muscles. Whether this is appropriate depends on the degree of separation, symptoms, excess skin, and individual anatomy.
