I gained 23kg between diagnosis, surgery and end of chemo. I was able to lose it steadily after a month recovery and have since lost all of the amount I put on. Still need a few more but just settlibg presently. So I'm through menopause and on hormobe blockers so it can be done.
Now your original weight was a little under a healthy bmi so yes...it would be an adjustment.
You can definitely lose it once treatment has completed. I stopped weighing in as it stressed me out so much. The chemo nurses just recorded the weight for me and we didn't discuss it. Kath x
