I've also lost some height, but I do have osteoporosis. I used to be 5' 1" and I have probably lost 1/4 of an inch. Not so much, and hopefully it's stopped, as I am finally on a medication that has not caused side effects. I won't find out until May, when I have my Dexa scan.
Roxy, I hope you can find your way with your nutrition. It sounds like you are healed physically and soon enough you will be on your bike.
