hypomagnesemia

 [hi″po-mag″nĕ-se´me-ah]
abnormally low magnesium content of the blood, manifested chiefly by neuromuscular hyperirritability. See table of Electrolyte Imbalances at electrolyte.

hy·po·mag·ne·se·mi·a

(hī'pō-mag'nē-sē'mē-ă),
Subnormal blood serum concentration of magnesium; may cause convulsions and concurrent hypocalcemia.

hypomagnesemia

Low blood magnesium, magnesium deficiency Metabolism A serum magnesium ≤ 1.5 mg/dL, often manifest by muscular hyperirritability Etiology Alcohol abuse, burns, dehydration, DKA, diarrhea, ↑ Ca2+, ↑ aldosterone, ↓ K+, ↓ PTH, post-bowel resection, malabsorption, malnutrition, pancreatitis, renal insufficiency, therapy with amphotericin B, calcium gluconate, diuretics, insulin, neomycin Clinical Cramping, ↑ tendon reflexes, tremors. See Magnesium.

hy·po·mag·ne·se·mi·a

(hī'pō-mag'nĕ-sē'mē-ă)
Deficiency of magnesium in blood; may be caused by chronic alcoholism, dehydration, diabetic acidosis, and chronic diarrhea, malabsorption syndrome, postoperative complication of bowel surgery, prolonged nasogastric suction, prolonged diuretic therapy, or starvation. Signs include arrhythmias, neuromuscular irritability, leg cramps, mood changes, confusion, hallucinations, or seizures.
Synonym(s): hypomagnesaemia.

Of 414 patients in a managed care cohort who received long-term PPIs, only 8 had mild hypomagnesemia (1.21.5 mg/dL) on nearly 14% of their combined 289 measurements.
The main reason for hypomagnesemia in SBS is primarily malabsorption due to various factors previously described (18, 24).
Therefore, and after ruling out another possible etiology for PRES, we suspected hypomagnesemia. This was confirmed in the chemical analysis that disclosed a particularly low magnesium level of 0.4 mg/ dl (range: 1.7-2.55 mg/dl).
Several studies have shown that hypomagnesemia is a common electrolyte derangement in clinical setting especially in patients admitted to intensive care unit (ICU) where it was found to be associated with increased mortality and hospital stay [23-25] (Table 4).
Risks can be increased by comorbidities such as diabetes, hypercholesterolemia, hyperglycemia, smoking, hypertension, as well as electrolyte disorders (hypokalemia, hypomagnesemia) and association of diuretics.

The paper begins with an observation of how often potassium and magnesium deficiencies are found concurrently: "Patients with congestive heart failure ...frequently show hyponatremia, hypokalemia, and hypomagnesemia."
CNIs also lead to tubular functional alterations and ion homeostasis disturbances like hyperkalemia, hypomagnesemia and magnesium wasting, distal tubular acidosis, and hyperuricemia.
