Based on my experience and knowledge, I'd have as little as possible removed provided this is a benign condition (almost all fibroids are benign).
You think peri is bad, thankfully it's only temporary! Having ovaries removed (or their common failure after hysterectomy) puts you in a permanent state of hormone / endocrine havoc. With natural menopause, the body "settles in" and the ovaries continue producing hormones for decades (in their endocrine / non-reproductive role) especially testosterone that your body converts into estrogen on an as needed basis. These hormones are vital to every aspect of health and no HRT can adequately compensate for ovary removal or ovarian failure. Medical studies show that ovary removal (which would also be true for failure) is associated with accelerated aging / increased mortality in the way of heart disease, stroke, osteoporosis, dementia, Parkinsonism, memory and cognitive impairment, lung cancer, ocular changes, skin changes. Those are the ones I recall off the top of my head! Studies also show negative effects on mood, sleep and sexual function.
The uterus also has life long functions. It's a place holder for the bladder and bowel which is why many women have bladder and bowel problems especially in the long-term. Studies show an increased risk of incontinence and prolapse.
The uterus and cervix are key to a satisfying sex life for many women. (So are the ovaries.)
The ligaments that hold the uterus in place are the pelvis' support structures. That's why women's figures gradually change after hysterectomy. The midsection compresses and thickens and their bellies protrude. They lose their waist which is a buffer between the rib cage and hips. This leads to chronic back, hip and midsection pain or discomfort.
My organs were unnecessarily removed 10 years ago and it has negatively affected every aspect of my life. I was shocked that anyone could age so quickly! By 4 months post-op, I had lost so much hair, it became fine, dry, and frizzy and sections turned gray plus I lost a lot of skin collagen causing wrinkly and saggy skin causing me to look 15 years older. I became severely depressed, anxious, irritable, overwhelmed by everything, couldn't concentrate, couldn't remember anything (to the point of being scary), vision became blurry, couldn't sleep more than 2 or 3 hours at a time, body overheated easily, had zero energy or motivation, lost strong feelings of love for husband and children, lost all libido and sex was extremely disappointing. My bladder and bowel didn't work properly and bowel problems have never resolved. Bladder acts up occasionally. I have many close female relatives and none of them who are intact and have gone through natural menopause have had these problems. Their only complaints have been disrupted sleep and worse memory.
I have been on HRT and although most hormonal symptoms have improved, I'm nowhere near the vibrant, happy, social and sexual person I was before the surgery. I still miss the closeness I felt with my husband and children as well as a libido and satisfying sex life. I'm never comfortable in social situations and lack the ability and interest to do all the things I used to. And my hair has never stopped falling out and is so dry, fine and frizzy! And the figure changes (that became apparent before the second year) along with the ever increasing back and hip discomfort have been just as distressing!
It's quite shocking what happens even though it's a common surgery and presented as "benign" ...certainly not something to take lightly!
What are your symptoms - heavy bleeding? Frequent urination? Pain? How big are your fibroids? Please advocate for yourself since you are the one who has to live with the consequences. Best of luck to you!
