I have Ehlers Danlos Syndrome and Osteopenia. Ive also suffered from kidney stones my entire adult life. After analysis I was told several times my kidney stones were caused by too much calcium in my diet. Obviously I cant be both getting too much calcium and not enough! Im wondering if it might be just a calcium absorption problem? How might I fix this?
Calcium levels in the body is regulated at three different levels. Amount of absorption at the level of intestines, Excretion from the body at the level of kidneys and mobilization of calcium stores from your bones and all three are dependent on hormone levels in your body. You could have excess mobilization of calcium from your bones or inadequate deposit in to bone both causing osteopenia. On the other had one of the cause for formation of urinary stones may be excess excretion of calcium in the urine and this may be independent of what happen at bone level. Have you had 24 hour urine collection to check for increased calcium excretion in the urine or other abnormalities that makes you prone for stone formation? Dietary advice for calcium is better guided by this result.
