Question 19

Regina is a vegan (a vegetarian that does not eat any animal products including dairy or eggs). After a series of unexplained bone fractures, her doctor completes some tests and discovers that her levels of parathyroid hormone are elevated.

Accepted Answer

A)  The lack of meat in her diet is causing anemia and preventing bone growth. 
B)  The lack of dairy in her diet has severely restricted the amount of calcium she has available. This deficiency stimulated the release of PTH, which caused more of the calcium stores in her bones to be mobilized. The deficiency has gone on for so long that she has weakened her bones.
