Hypomagnesemia primary


Hypomagnesemia primary: Low blood magnesium levels which is caused by the abnormal absorption and excretion of the mineral and can be caused by such things as kidney problems and intestinal malabsorption.

ome causes of renal disease, such as glomerulonephritis, pyelonephritis, and renal tubular acidosis, may produce hypomagnesemia by impairing renal magnesium reabsorption. However, it is important to remember that with advanced renal disease (GFR less than 10ml to 25ml/hr), hypermagnesemia usually results from impaired renal magnesium excretion. Pancreatitis may cause hypomagnesemia in much the same way it causes hypocalcemia. In addition, any condition associated with hypercalcemia, such as excessive doses of vitamin D or calcium supplements, may result in renal magnesium loss. It should be noted that magnesium and calcium share a common route of absorption in the intestinal tract and appear to have a mutually suppressive effect; thus, if calcium intake is unusually high, calcium will be absorbed in preference to magnesium and vice versa. Magnesium deficiency has also been described in burn patients and is possibly related to loss of magnesium during debridement and bathing of denuded skin. Other conditions thought to predispose to hypomagnesemia are sepsis and hypothermia.


Once the deficiency is corrected, patients have and excellent prognosis. The symptoms are for the most part completely reversible with treatmen
