Magnesium status depends on three organs: uptake in the intestine, storage in the bone, and excretion in the kidneys.<unk>  is therefore often due to problems in these organs, mostly the intestine or kidney. Predisposing conditions * Hemolysis, magnesium concentration in red blood cells is approximately three times greater than in serum, therefore hemolysis can increase plasma magnesium.<unk>  is expected only in massive hemolysis. * Chronic kidney disease, excretion of magnesium becomes impaired when creatinine clearance falls below 30 ml/min. However,<unk>  is not a prominent feature of chronic kidney disease unless magnesium intake is increased. * Magnesium toxicity from emergency pre-eclampsia treatment during labor and delivery. * Other conditions that can predispose to mild<unk>  are diabetic ketoacidosis, adrenal insufficiency, hypothyroidism, hyperparathyroidism, and lithium intoxication. Metabolism For a detailed description of magnesium homeostasis and metabolism see hypomagnesemia.
