http://www.panix.com/~paleodiet/losspts.txt has many answers to these
questions. If you follow that advice you'll know more than 99% of
osteoporosis patients (and many physicians!).
Calcium loss is often a slow process, and Calcium regain is hard to achieve
and always slow- normally physicians count it as a success if they can
simply stop further calcium loss. If you actually gain bone density (usually
takes 12-18 months to see a change), you're in the lucky few. Actual gain in
bone density is the holy grail of osteoporosis therapy- not yet achieved
despite the claims of some drug companies.
Cortisone REPLACEMENT therapy for Addison's disease shouldn't necessarily
cause osteoporosis if you're not over-replaced (ie only receiving
physiological doses like 25mg hydrocortisone/day)(equivalent to wht normal
people's adrenal glands make. Over-replacement of thyroid hormone erodes
bone density- so perfect balance (euthyroid) is best. Follow your doctors's
recommendations on these critical hormones.
By looking after your lifestyle so carefully, you have a very big advantage.
Be patient, repeat your bone mineral density test each 12-18 months.
