Causes include low dietary intake, alcoholism, diarrhea, increased urinary loss, and poor absorption from the intestines. [1] [4] [5] Some medications may also cause low magnesium, including proton pump inhibitors (PPIs) and furosemide. [2] The diagnosis is typically based on finding low blood magnesium levels, also called hypomagnesemia. [6]
Normal magnesium levels are between 0.6 and 1.1 mmol/L (1.46–2.68 mg/dL) with levels less than 0.6 mmol/L (1.46 mg/dL) defining hypomagnesemia. [21] Specific electrocardiogram (ECG) changes may be seen. [21] Causes include low dietary intake, alcoholism, diarrhea, increased urinary loss, poor absorption from the intestines, and diabetes mellitus.
[5] [6] Magnesium is a cofactor for adenylate cyclase, which catalyzes the conversion of ATP to 3',5'-cyclic AMP. The 3',5'-cyclic AMP (cAMP) is required for parathyroid hormone activation. [ 7 ] It is frequently seen in alcoholics, persons with diarrhea, patients taking aminoglycosides or diuretics, because hypomagnesemia can cause hypocalcemia.
Hypomagnesemia is relatively straightforward to diagnose, as it is characterized by a low serum magnesium level below 1.5 to 1.8 mg/dL [milligrams per deciliter]. However, total body magnesium ...
Common causes in pediatric patients may be diarrheal illness, frequent feedings with dilute formula, water intoxication via excessive consumption, and enemas. [3] Pseudohyponatremia is a false low sodium reading that can be caused by high levels of fats or proteins in the blood.
Gitelman syndrome; Other names: Primary renal tubular hypokalemic hypomagnesemia with hypocalciuria: A model of transport mechanisms in the distal convoluted tubule.Sodium chloride (NaCl) enters the cell via the apical thiazide-sensitive NCC and leaves the cell through the basolateral Cl − channel (ClC-Kb), and the Na + /K +-ATPase.
Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic.
[2] [3] [8] Anemia: Anemia is related to numerous and/or consecutive treatments and/or large extracorporeal circuits that reduces the hemoglobin levels in pediatric patients. [2] [3] Hemoglobin is responsible for oxygen transport in the blood. [2] Pediatric considerations to reduce incidence of anemia: Close monitoring of hemoglobin levels. [3]
