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

/hy·po·mag·ne·se·mia/ (-mag″nes-ēm´e-ah) abnormally low magnesium content of the blood.

hypomagnesemia

[hī′pōmag′nisē′mē·ə]
an abnormally low concentration of magnesium in the blood plasma, which causes nausea, vomiting, muscle weakness, tremors, tetany, and lethargy. Tachycardia and arrhythmia may also occur. Mild hypomagnesemia is usually the result of inadequate absorption of magnesium in the kidney or intestine, although it is also seen after prolonged parenteral feeding and during lactation. A more severe form is associated with malabsorption syndrome, protein malnutrition, and parathyroid disease. Magnesium salts to correct the deficiency may be given orally or intravenously.

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.

hy·po·mag·ne·se·mi·a

(hī'pō-mag'nĕ-sē'mē-ă)
Subnormal blood serum concentration of magnesium; may cause convulsions and concurrent hypocalcemia.
Synonym(s): hypomagnesaemia.

hypomagnesemia (hī´pōmag´nəs-ē´mēə),

n a deficiency of magnesium in the blood serum (normal values range from 1.5 to 2.5 mEq/L). It may be associated with chronic alcoholism, starvation, and prolonged diuresis in congestive heart failure. Manifestations include muscular twitching, convulsions, and coma.

hypomagnesemia

abnormally low magnesium content of the blood, manifested clinically by neuromuscular excitability.
