Great news
I've been diagnosed so :-
"How did you do it?"
A very high calcium, selenium, silica, magnesium, boron diet. Plus a few other of the scarce minerals
There's a Solgar bone supplement that's useful, plus I made sure I had about a litre of Almond milk a day (not the organic one, it's not fortified) (I can't had cows milk, I'm allergic to it) and in addition to that 1/2l of nettle tea a day. Home-made nettle tea not the shop bought stuff. It needs to steep overnight to get the minerals put of the nettles. Nettles are very highly nutritious and very underrated. Get dried nettles unless you have a very good nettle patch. I used to buy them from The Spiceworks, Hereford.

It took 2 years but was much better than taking the prescribed medication which for me was untested and not recommended on premenapausal womenn plus had some really nasty side affects.
You may not want the hassle but some things i prefer to do naturally rather than through medication. Plus you need to include some walking each and every day to make use of the minerals you are consuming.
