Your first stop for diastasis recti is typically your OB-GYN or primary care doctor, who can confirm the diagnosis with a simple physical exam. From there, the provider you need depends on how severe the separation is and whether you’re looking at conservative rehab or surgical repair. Most people will work with a pelvic floor physical therapist as their primary treatment provider, while larger or more complex cases may require a general surgeon or plastic surgeon.
Starting With Your OB-GYN or Primary Care Doctor
Diastasis recti is diagnosed when the gap between your left and right abdominal muscles measures wider than 2 centimeters, roughly two finger-widths. Your OB-GYN or primary care provider can check for this during a standard office visit by having you lie on your back and do a small crunch while they press along the midline of your abdomen. They’re feeling for the width and depth of the gap, as well as how much tension the connective tissue between the muscles can generate.
In most cases, that hands-on exam is enough to make the diagnosis. If the gap is hard to assess (for instance, if there’s a thicker layer of tissue over the abdomen), your doctor may order an ultrasound. Ultrasound is considered the go-to imaging tool for measuring the separation because it’s noninvasive, accurate, and easy to repeat over time to track progress. CT scans or MRI are generally reserved for patients who are being evaluated for surgical repair, since plastic surgeons often want more detailed imaging before planning a procedure.
Once your doctor confirms the diagnosis, they’ll typically refer you to the appropriate next provider based on the size of the gap, your symptoms, and your goals.
Pelvic Floor Physical Therapist: The Most Common Referral
For mild to moderate diastasis recti, a pelvic floor physical therapist is the specialist you’ll spend the most time with. These therapists focus specifically on the muscles of the core, pelvic floor, and abdomen, making them uniquely qualified to design a rehab program for abdominal separation. When searching for one, look for a therapist with specific training in postpartum recovery or pelvic health rather than a general orthopedic PT.
The core of treatment (literally) is a progressive exercise program built around deep core stabilization. In a randomized trial of 40 postpartum women, those who did targeted core stability exercises alongside traditional abdominal work saw significantly greater reduction in their gap after 8 weeks compared to women who did traditional ab exercises alone. They also reported meaningful improvements in quality of life. Importantly, research has shown that exercises like curl-ups can build abdominal strength without making the separation worse, which is a common fear.
Your PT may also incorporate hands-on manual therapy, abdominal binders, taping techniques, or biofeedback tools that help you learn to activate the right muscles. A small study found that combining belly bands with targeted exercises improved body image in first-time mothers over six months. Pilates-based programs have also shown benefits, reducing the gap while improving abdominal endurance and waist circumference. Most of the research on physical therapy outcomes focuses on the 6 to 12 month postpartum window, so starting within that timeframe is ideal, though therapy can help at any stage.
General Surgeon vs. Plastic Surgeon
If physical therapy doesn’t close the gap enough, or if the separation is large and causing functional problems like lower back pain, poor core stability, or a visible bulge, surgery becomes an option. This is where the choice of doctor gets more nuanced, because general surgeons and plastic surgeons approach diastasis recti repair quite differently.
A general surgeon typically treats diastasis recti as a functional problem. Their focus is on stitching the separated muscle walls back together, sometimes using reinforcing mesh, and they may approach this as a standalone repair without addressing the surrounding skin or fat. If your main concerns are core weakness, back pain, or the mechanical dysfunction caused by the gap, a general surgeon or hernia specialist is a reasonable choice. At many hospitals, patients with a large separation are referred to a hernia specialist first.
A plastic surgeon, on the other hand, approaches diastasis recti primarily as an aesthetic and functional problem combined. In their hands, the repair is almost always performed alongside an abdominoplasty (tummy tuck), which tightens the muscle wall while also removing excess skin and reshaping the abdomen. Plastic surgeons will often repair even a relatively small separation during an abdominoplasty to maximize contour. If your concerns include both the gap itself and changes to your abdominal appearance after pregnancy, a board-certified plastic surgeon is the more appropriate specialist.
The distinction matters for what your recovery looks like, what your final result will be, and how your insurance handles the claim. A standalone functional repair by a general surgeon is more likely to be covered by insurance, while a combined abdominoplasty is often classified as cosmetic.
What to Ask During a Surgical Consultation
If you’re referred for surgery, a few questions will help you compare providers and set realistic expectations. Ask whether the repair will be done as a standalone procedure or combined with an abdominoplasty, since this affects both the scope of the surgery and the recovery. Ask about the expected recovery timeline, what kind of help you’ll need at home in the first weeks, and when you can return to exercise and normal activity. If mesh will be used to reinforce the repair, ask about the type and whether it changes the long-term outlook. Finally, ask where the procedure will be performed and whether it’s done under general anesthesia or sedation.
Insurance and Getting the Right Referral
One practical challenge with diastasis recti is that it doesn’t have its own dedicated diagnostic code in the medical billing system. Providers typically code it under categories for abdominal muscle strain, which can sometimes create friction with insurance approvals for physical therapy or surgical referrals. If you’re having trouble getting coverage, ask your provider about the specific codes they’re using and whether a letter of medical necessity would help. Documenting functional impairment, such as back pain or inability to perform daily tasks, strengthens the case for coverage.
For physical therapy, many insurers cover a set number of visits per year without requiring a referral, but others need one from your primary care doctor or OB-GYN. Checking your plan’s requirements before booking your first PT appointment can save you a billing headache later.
The Typical Path From Diagnosis to Recovery
For most people, the journey looks like this: your OB-GYN or primary care doctor confirms the separation, refers you to a pelvic floor physical therapist, and you spend 8 to 12 weeks working through a structured core rehabilitation program. Many people see meaningful improvement in both the gap size and their symptoms during that window. If progress stalls, or if the separation was severe from the start, your doctor refers you to a surgeon for evaluation, and imaging like CT or MRI is ordered at that point to plan the procedure.
The key is not to skip straight to a surgeon or, conversely, to spend months doing random core exercises from the internet without professional guidance. A pelvic floor PT can tell you which movements are safe and which ones (like traditional crunches or heavy lifting) might make the separation worse. Starting with the right provider from the beginning saves time and gets you to a better outcome.
