Last week HuffPost ran a piece by a mother of three who paid out of pocket to repair the abdominal wall that pregnancy had separated. The editor reached out to me for the surgeon’s perspective. I will repeat here what I told them.
Insurance companies will prescribe painkillers for decades to manage the back problems caused by an unrepaired diastasis recti. They will not pay to repair the separation itself. They will call the repair cosmetic, because the separation is not an emergency. That word, “cosmetic,” is doing an enormous amount of work in that sentence, and most of it is wrong.
Diastasis recti is not a flat-stomach problem. It is a structural problem with a cosmetic side effect.
What Diastasis Recti Actually Is
You have two long bands of abdominal muscle running down the front of your torso, one on each side of your midline. They are connected in the middle by a thin sheet of connective tissue called the linea alba. Pregnancy stretches that sheet. So does certain types of weight gain. In some women, the sheet stretches and recovers. In others, it stretches and stays stretched, and the two muscle bands stay further apart than they were before.
That is diastasis recti. The muscles themselves are fine. The wall between them is not.
When the wall between them is loose, the core can no longer brace the way a closed abdominal wall braces. Standing posture changes. The lower back has to do more work. Pelvic floor symptoms get worse. Some patients develop a visible dome that appears when they try to sit up out of bed. Some develop a true ventral hernia at the umbilicus and need a repair regardless of how the rest of the abdomen looks.
None of that is cosmetic.
How to Tell Diastasis Recti from the Other Things It Gets Confused With
This is the comparison most postpartum women are not given. They walk into a primary care visit, they describe a soft belly that did not bounce back, and they leave with “try some core work.” That is sometimes the answer. Sometimes it very much is not.
| Diastasis Recti | Loose Skin Only | Soft Postpartum Belly | |
|---|---|---|---|
| What is separated | Linea alba is stretched, rectus muscles sit apart | Nothing structural | Nothing structural |
| Visible sign | A dome or ridge when you try to sit up from lying flat | Skin laxity, stretch marks | Soft fullness that responds to weight loss |
| Back pain pattern | Common, often years of it | Uncommon | Uncommon |
| Hernia risk | Real | Low | Low |
| Helped by core PT alone | Sometimes, sometimes not | No | Yes |
| What a real repair requires | Plicating the rectus muscles back to midline, surgically | Skin excision | No surgery at all |
| Insurance label | “Cosmetic” | “Cosmetic” | N/A |
The table is honest about what physical therapy can do and what it cannot. For some patients, a good pelvic floor and core program closes the gap enough that they live a normal active life. For others, the connective tissue is permanently stretched, and no amount of training will rejoin it. PT cannot reattach a ligament. PT cannot close a hernia. PT cannot bring two muscle bellies that have been pulled apart by three pregnancies back to the midline.
When PT is the answer, I send patients to PT. When PT is not the answer, I tell them that too.
Who Is a Candidate for Surgical Repair
I look for three things in consultation. First, a real, measurable diastasis on physical exam, ideally confirmed on ultrasound or CT if the case is complicated. Second, symptoms that match the anatomy: back pain that started or worsened after pregnancy, core weakness, pelvic floor strain, the visible dome, or an umbilical hernia. Third, a patient who is finished having children and is at a weight she can hold steady through recovery.
If all three are present, surgical repair (most often as part of a tummy tuck, sometimes as a standalone abdominal wall reconstruction) is the operation that actually solves the problem. The rectus muscles are plicated back to the midline with permanent or long-acting suture. Loose skin and stretched lower-abdominal tissue are addressed at the same time. A hernia, if there is one, is repaired in the same operation.
That is a real surgery. It is not a vanity procedure. The fact that the patient also looks like herself again when she heals does not retroactively make the medical problem cosmetic.
Why the Insurance Argument Bothers Me
Here is what insurance pays for happily. Years of physical therapy that did not work. Anti-inflammatory medications. Muscle relaxants. Eventually opioids for the back pain. Specialist visits for the pelvic floor. Hernia repairs when the umbilical hernia finally herniates, because at that point the structural argument is impossible to deny.
Here is what insurance will not pay for. The one operation that addresses the root cause before the years of medication and the eventual hernia repair.
That is not medical sense. That is accounting.
I told HuffPost what I will tell you. The word “cosmetic” is being used as an exclusion code, not a clinical description. Diastasis recti repair has a strong functional rationale. The peer-reviewed literature has been catching up for years. A handful of insurers are starting to cover it under narrow circumstances. Most still will not.
Why You Want This Done Right
A diastasis repair done poorly recurs. The suture line pops, the dome comes back, the symptoms come back, and the patient now has a scar and a redo on her list. A diastasis repair done well lasts decades.
What separates the two is technique. The closure has to be tension-balanced and layered. The plication has to extend the full length of the diastasis, not just the visible portion. The surgeon has to understand the umbilical stalk well enough to address a small hernia if one is hiding there. The recovery instructions have to actually protect the repair while it heals.
I trained in general surgery before I trained in plastic surgery. I did my plastic surgery fellowship at Mayo Clinic. I teach abdominal wall and body contouring as a Clinical Associate Professor of Plastic Surgery at Texas Tech University Health Sciences Center. I have been Castle Connolly Top Doctor for thirteen consecutive years. I am explaining the procedure to you the way I explain it to the residents and fellows who scrub with me. Because that is the version that actually holds up.

If you have been told for years that what you are feeling in your abdomen is “just being a mom,” or that the back pain that started after your last delivery is something you need to live with, come see me. I will examine you, tell you whether what you have is a diastasis, and tell you honestly whether surgery is the right answer for your case. If physical therapy is still your best move, I will say that. If repair is the right answer, I will explain what that operation involves and what your recovery looks like.
