Thanks for your quer.
After a hysterectomy
, wherein your ovaries too were removed, menopausal symptoms would kick in within a month or two.
This is not a rule of thumb, and some women go through this phase beautifully without major hiccups.
Also, normally a uterus
weighs around 70 gms.
The weight loss
could be due to the huge fibroid
itself, which again can be weighed separately as a specimen after removal.
You do not need to do math and guesswork.
