I am type one, I had a hysterectomy when I was 24, both ovaries - instant menopause.

Osteoarthritis is wear and tear of the joints osteoporosis is porous bones .

This is what I found at the Spine Health website

There are two types of osteoporosis:
Type I osteoporosis (postmenopausal osteoporosis) generally develops in women after menopause when the amount of estrogen in the body greatly decreases. ...
Type II osteoporosis (senile osteoporosis) typically happens after the age of 70 and affects women twice as frequently as men.

Hi Tracey, If you are asking about Osteoporosis I and Osteoporosis 2, I would also like to know more about that: mine has just been called "Osteoporosis". Are there different grades? Can anyone help us with details? Thanks.

Yes, I am aware of that - runs in my family. When I see my rheumatologist in fall I will ask him about this. Thank you for getting back to me
