S. O.,
I had a hysterectomy when I was forty, and it was fine. I had one ovary taken (ooverectomy),and a hysterectomy together. I had suffered from long periods, heavy 8 days a month. I had major crampy, and fybroid problems. I held off for many years, trying everything to keep from having one. First off, if you keep an ovary, you do not have a hormone imbalance. It only happens if you have the ovaries removed. Then they usually put you on hormones until you hit menopause. Yes, you will still go through premenopause, and menopause. When they went to do the surgery, they found that I had endometriocis and adnomyosis. That is fibroids inside and outside the uterus. I had tried all types of exercise, running and such. I managed to cut my period by one day a month. But, it put me in shape for the surgery. I recovered very quickly and completely.
If you are sure that you do not want any more children, then go ahead. But if you are not sure, wait. My mother, and two of my sisters also had to have hysterectomies. The sisters had their ovaries removed and had to deal with adjusting meds, etc. I had no hot flashes. They had to deal with them immediately. If you can hold off for a while, and want to try again to have the fibroids removed do so. I know I had to have one, but sometimes you wonder why it had to happen to me. The reason I am saying to wait if possible, is there are so many ways of dealing with fibroids now. Medications, minor surgery, and possibly other alternatives. I gained about 5 lbs over a period of time after the surgery. My doctor told me a weight gain of 5 or 10 lbs is normal. I was still able to do 40 sit ups in a row after the surgery. You can still exercise, and you will have a scar in the pubic hairline where the incision was made. It is well hidden though. Stress and hereditary factors played a role in my surgery. I also was anemic most of the time, that got old and I was tired of that. No pun intended. So for me, it was time, and necessary for me to have the hysterectomy.
Do get a second opinion. I did, and it made me feel better about the surgery.
I know this could have been better organized, but I hope the information calms you and you feel more informed. If you have any more questions or need more information, just send me a message.
