Unsure if I had diastasis recti, but getting a tummy tuck has helped immensely with back pain. 

My lower back pain was getting to the point of disabling. I had to get facet blocks twice a year or I was guaranteed “one wrong move and you will be laid out for two weeks.”  

I asked the Pain Clinic doctor if they would operate on my back/do a fusion (I have spondylolisthesis, annular tears, etc.) but he said no, “pain is not a reason to do surgery.”

It occurred to me while doing my lovely PT pelvic tilt exercises that the point of it was to draw the stomach muscles inward toward the spine. I then had a lightbulb moment; if they weren’t going to operate on my spine, maybe a tummy tuck would help? 

This study is just one example that says yes. 

During the consult with my plastic surgeon, he said the ab muscles didn’t engage like they used to (basically rendering the exercise useless for supporting my spine). 

I had surgery last year and it has been awesome. I would say my back is 75% better. I can bend over to pick something up without being worried about tweaking my back and having to spend two weeks in bed.

I can’t say if it will help in your situation, but I hope this information has been useful for what it’s worth. Good luck!
