Boy! Is this a loaded question! My illness, that created all my "osteoporosis issues", is genetic. I wish my Mother had told me & my 4 syblings about this dis-order. I found out, after searching thru & talking with, many relatives & medical records. My Mother, was one of two children, out of ten, that refused to beleive, she had this dis-order and that it IS genetically passed on, @ a 50-50 chance of inheriting it! Yet, she NEVER mentioned it to me, even after telling her of my early signs of "high calcium", in my blood! Her response, when I questioned, "Why would this be?" "I have NO idea!" Even though she had, had 3 0f 4 Parathyroids removed in "1967", due to Adenomas! Our Parathyroids, produce our Calcium. Although I had high balances of it, in my blood, it should have been going to my bones! Hence, all the kidney stones, while a teenager, (what was she thinking?) my bones were already, @ age 33, in "Hungry Bone Syndrome!? I then developed a broken hip @ age 35. It goes on & on. All I know is, IF, I had known this genetic dis-order even existed in our family, I certainly would have given A-LOT of thought of re-producing children @ a significant risk of inhereting this disease! My children have watched me go thru some 24, or so surgeries, to date! Not to mention, my son, has already been diagnosed with "High Calcium!" Hopefully, I caught it @ an early enough point in his life, that he may be spared some of the pain & anquish, I am living. I am now seeing signs in my daughter, which she is ON TOP OF IT! One thing I can say is, If you feel something, IS NOT RIGHT, in your body, follow up on it! You MUST be PRO-ACTIVE in ANY medical relationship, with any Dr., & or disease! If you have questions, ASK! If you don't like the answer, GET ANOTHER OPINION! I have learned SOOOOO much thru the last 12 or so years, it's scary, yet, I must press on, because NOONE else is going to do it for you!! Not even, my Mother.....periwinkle
