What is rectus diastasis and how is it treated?

Rectus diastasis, also known as diastasis recti, is a condition where the two vertical muscles of the abdomen (the rectus abdominis) separate along the midline. It often presents as a visible bulge or ridge in the stomach area and may lead to core weakness, discomfort, or changes in posture.

While it’s commonly seen after pregnancy, it can also affect men and women due to factors such as obesity, repetitive strain, or significant weight fluctuations.

Understanding rectus diastasis

The rectus abdominis muscles are normally joined by a band of connective tissue called the linea alba. When this tissue becomes stretched or weakened, the muscles can drift apart, creating a gap. Although it may resemble a hernia, rectus diastasis does not involve a tear or defect in the abdominal wall, but rather a thinning and widening of the central connective tissue. 

Patients often notice a ridge or bulge down the centre of the abdomen, especially when sitting up or straining. Other symptoms can include lower back pain, poor posture, and difficulty engaging the core muscles during physical activity.

When is treatment needed?

Not all cases of rectus diastasis require surgery. In mild cases, physiotherapy and targeted core exercises may help strengthen the abdominal wall and reduce the gap. However, when the separation is significant or causes functional problems, surgical repair may be recommended. It may also be performed alongside other procedures, such as hernia repair or abdominoplasty (tummy tuck), particularly in post-pregnancy cases.

What does surgical rectus diastasis repair involve?

Surgical correction of rectus diastasis involves bringing the separated muscles back together and reinforcing the midline. Mr Ahmed specialises in advanced keyhole surgery and can offer laparoscopic diastasis suture repair with or without mesh reinforcement. The main objective here is to use a suture to reapproximate your rectus muscles to the midline using keyhole surgery without any large incisions.

On occasion Mr Ahmed may combine laparoscopic diastasis repair with umbilical hernia repair should they co-exist. The benefits of the laparoscopic approach are as for any laparoscopic versus open technique, most notably improved recovery time, reduced pain and wound infection, improved cosmesis.

Most insurance companies regard rectus diastasis surgery as cosmetic and so will not usually cover it.

Rectus diastasis is a common condition that can affect both physical function and self-confidence.
