Sorry, I'm a recent convert and not used to how much information is needed. The hiatus hernia is a long standing problem dating from way before the hysterectomy, although only recently diagnosed for sure. I take oestrogen, daily in the form of a gel which is rubbed into my upper arms. I have had no problems with this apart from a weight gain. My blood pressure is checked regularly and is always normal.As far as I know no damage was done during op. I did make a very quick recovery.
