What's the deal with separated abdominal muscles?

By Dr. Killeen, published on July 23, 2022

So what's the deal with rectus diastasis? Separation of your abdominal muscles can happen for a variety of reasons and can be repaired!

Rectus diastasis, also known as diastasis recti, is the separation of the rectus abdominis muscles (your "six-pack" muscles) along the midline of your abdomen. This condition is incredibly common, especially among women who have been pregnant, but it can affect anyone.

What Causes Rectus Diastasis?

The most common cause is pregnancy, where the growing uterus stretches the abdominal muscles and the connective tissue (linea alba) that holds them together. However, rectus diastasis can also result from:

• Rapid weight gain or loss
• Heavy lifting with improper form
• Genetic factors affecting connective tissue strength
• Age-related weakening of abdominal muscles
• Certain medical conditions

Signs and Symptoms

You might have rectus diastasis if you notice:

• A visible bulge or "doming" when you engage your core muscles
• A gap you can feel between your abdominal muscles
• Lower back pain or core weakness
• Difficulty with certain movements or exercises
• A persistent "pooch" in your midsection despite exercise

Can It Be Repaired?

Absolutely! While mild cases may improve with targeted physical therapy and specific exercises, more significant separations often require surgical intervention for optimal results.

Surgical repair of rectus diastasis is commonly performed during a tummy tuck (abdominoplasty) or as part of a mommy makeover. During this procedure, I bring the separated muscles back together and secure them with sutures, restoring core strength and improving the abdominal contour.

The Benefits of Surgical Repair

Repairing rectus diastasis can provide:

• Improved core strength and stability
• Better posture and reduced back pain
• Enhanced abdominal contour
• Increased confidence in physical activities
• Better-fitting clothes and improved body image

If you suspect you have rectus diastasis, it's worth having it evaluated. This common condition is very treatable, and repair can significantly improve both function and appearance.
