Prolapse has much to do with a weak core and pelvic floor disorder. Its a pressure problem. Pregnancy gets the blame, but organ prolapse is a male and non mother problem too. Pregnancy can exacerbate underlying issues bringing them to the surface sooner than later. There are restorative exercises you can do. Prolapse is really a symptom of a bigger problem, uncontained intra abdominal pressure. You have to fix the pressure problem.
While prolapse is not something I have experienced, I am at risk of it because of a diastasis recti and a weak pelvic floor. This is separation of your TVA muscles and the latter poorly functioning "down there" muscles.
Pelvic floor disorder is probably the culprit here. Its when our pelvic floor muscles are no longer taught and elongated. This is likely a posture/ alignment issue. We have all mistakenly learned to tuck our tail bones and some of us walk and stand in turn-out instead of toes forward. . This shortens the muscles and makes them less effective. Rather, we should all be in neutral spine, which feels like sticking you butt out. "when in doubt, stick your butt out." Look into this.

Any how, many of these posture/ alignment issues that lead to pelvic floor disorder and diastistist recti, create uncontained intra abdominal pressure, leading to prolapse, urinary incontinance, varicose veins and a host of other problems. The same issues above can also lead to knee pain and hip pain from improperly loading your joints. Do you by chance have knee tracking problems? Its all related. It boils down to proper alignment and strong core and pelvic muscles.
Here are two things I suggest you really look into:
the book "Alignment matters" by Katie Bowman.
https://www.alignedandwell.com
This is her Aligned and Well web page. You can access her blog "Katy says" or buy the blogs in book form (Alignment Matters) on Amazon or the above sight.
I suggest you pursue the "Katy says "blog to peak your interest for free. But the book is so much better organized.
Also, this exercise program below has helped a lot of people with pelvic floor disorder and distaste recti (remember, prolapse is a symptom of a larger problem, intra abdominal pressure, not the problem in and of itself).

I'm on the above programs forum and there is lots of talk of prolapse so I do hear that unless you have a very skilled cutting edge physician, they are not going to be able to provide you with non surgery corrections very well. Though, proper alignment and restorative exercises can be used for prolapse if you find the right professional help.
I'm sure you've heard of the Kegle. The most cutting edge biomechanical research says the squat is the new Kegel. Look into it.
There are many things you can do to fix your pelvic floor problems. Among them, proper restorative exercises, getting out of high heals, and learning proper alignment.
Happy research. Best of luck.
Also, there are prolapse support groups and forums out there. Get connected. There are probably a lot of changes you can make before considering surgery.
