Common risk factors for developing osteoporosis include:
--Having a small frame.
Thin people tend to have less dense bones than heavier people.
Part of the reason is that body weight puts stress on bone, stimulating it to form more bone.
Thin women may have less body fat and lower estrogen levels than heavier women.
Fat tissue produces some estrogen.
--Family history of osteoporosis.
If you have a close relative with osteoporosis, you're more likely to develop it.
