    What is (are) hypomagnesemia with secondary hypocalcemia ?
    ### Response:
    Hypomagnesemia with secondary hypocalcemia is an inherited condition caused by the body's inability to absorb and retain magnesium that is taken in through the diet. As a result, magnesium levels in the blood are severely low (hypomagnesemia).  Hypomagnesemia impairs the function of the parathyroid glands, which are small hormone-producing glands located in the neck.
