You will get many, many comments regarding this; some from at least one woman who is unhappy after having had hers and appears to blame many medical systms she has experienced since on this surgery. Other women who had gone through much pain and bleeding prior to this surgery seem to be far more satisfied afterwards.
As for me...I had mine at age 47; kept my ovaries; went in on a Thursday, home on Saturday, riding my bike on Monday; very little pain and I don't miss that puppy one bit.
Your mileage will vary quite a bit but I suspect that how you respond to this surgery might be tied into how confident you feel about your surgeon and how political you feel about the issue regarding hysterectomies in general. Those who feel that there are far too many hysterectomies being performed (and they may certainly be correct) appear to report more personal symptoms when they have to undergo this procedure themselves.
I'm not certain how much of this is an underlying anger at the medical profession for promoting this treatment for women experiencing reproductive symptom problems versus a depression at the loss of a body part connected with being a female. If one can accept that it's just another body part (albeit certainly one that most of us hope we can retain throughout our lifetime) then the decision to undergo a hysterectomy might be a bit easier psychologically for some women.
If you are underweight it is quite likely you are going to stop menstruating. Lose enough fat stores and muscle mass and menstruation stops and often does not start again until fat and muscle mass has improved to a certain point.
