Medical Definition of Hypomagnesemia. Hypomagnesemia: Low magnesium in the blood, which can occur due to inadequate intake or impaired intestinal absorption of magnesium. calcium (hypocalcemia) and low potassium (hypokalemia).
There are two types of hypomagnesemia recognized clinically, hypomagnesemic tetany in calves, which appears to be due to a straightforward deficiency of magnesium in the diet, and lactation tetany, in which there may be a partial dietary deficiency but in which nutritional and metabolic factors reduce the availability, or increase the body loss, of magnesium.
