First off I highly recomend this site even if you've already had a hysterectomy there is so much great advice for before and after:
www.hystersisters.com
I'm 44 and last December I had a partial abdominal hysterectomy, I was able to keep my cervix and left ovary, which helped with a faster recovery. Well so they say, I felt like it took a long time. The reason for the hyst was severe endometriosis, adenomyosis, fibriod tumors, enlarged uterus, overian cysts which included the tubes, and lastly because of the damage from the tumors I had bladder repair with a sling. Phew!! Of course different women have different experiences with recovery depending on what they have done and the extent of damage that has to be repaired. Thats where the Hyster Sister site is so helpful, it gives you a way to gage what you will need to have done and recovery time based on what they went through.
Now the surgery itself was hard, allot of pain and discomfort so it's best to be prepared for that, recovery was long and hard because of type of surg and problems being taken care of. They tell you for this type of surgery you will have six weeks of recovery, what they didn't say was you feel like crap for six weeks then s..l..o..w..l..y start to get better. Oh and the first two weeks were just awlfull sooo much pain.
But once past those first six weeks, wow life is so much better. Now four months later I am so happy I had this done my only regret is I waited so long to take care of this problem I wouldn't hesitate to do it again even knowing, yeah this is going to hurt and life is going to be hard for a couple of months, but compare 2 months with your whole life being just sucky because it revolves around this problem which affected everything.
Last week I went hiking with the kids over spring break, I did have the occasional shaky legs and had to work hard to keep up, but I was marching up hills jumping over tree limbs, rocks and everything else with no problems. I couldn't have done that last year.
To sum things up do your research first, the Hyster Sister is just great I can't say enough about it. But if the quality of your sisters life is affected get a good doctor and do what needs to be done.
