<<Disclaimer: Verify this information before applying it to your situation.>> I am 56 years old and have severe osteoporosis as a result of only being diagnosed with celiac sprue only 4 years ago. Unfortunately my doctors did not know much about celiac sprue and did not prescribed any preventive treatment for osteoporosis and when I retired from my job my bones retired by fracturing everywhere. I have reviewed the archives which had some good information but would like further assistance from the list members as follows. -Know of any bone endocrinologist located in Missouri. I live in a small town and the doctor situation is not pretty. -Has anyone taken 50,000 IV of vitamin D successfully without any problems? A blood test indicated I was low on vitamin D. -Good source for gluten, lactose, and sugar free calcium and vitamin D supplements. I now use Freeda and use the powdered form of calcium for better absorption (I hope). -Medication and any other recommendations that have been successful for list members with osteoporosis. -Recommendation for a vehicle with air ride or air suspension. My condition is so bad that when I go anywhere I ride in the back of a Suburban on an air mattress and several egg crates. A friend had a '93 Lincoln Continental that had a pretty soft ride and I have tried '92, '93, '96 Executive Town Car but the Town Car seems to have a tighter feeling ride that hurts. Plus I need a back seat that is wide and long enough to lie on (I am 5'2"). I am grateful to have this avenue to solicit assistance and will summarize the replies I receive. Thank you.
