UpToDate Causes of hypomagnesemia Regardless of the cause, hypomagnesemia begins to occur after a relatively small magnesium deficit, because there is little rapid exchange of extracellular magnesium with the much larger bone and cell stores. Hypomagnesemia is often associated with hypokalemia due to urinary potassium wasting and hypocalcemia due both to lower parathyroid hormone secretion and end-organ resistance to its effect. Common settings in which hypomagnesemia may be seen are when intestinal secretions are incompletely reabsorbed, as with most disorders of the small bowel, including acute or chronic diarrhea, malabsorption and steatorrhea, and small bowel bypass surgery. patients.uptodate.com /topic.asp?file=minmetab/8931   (392 words)

Geriatric Times Because the signs and symptoms of hypomagnesemia may be indistinct from those of other conditions, the deficiency is often difficult to identify clinically (Gullestad et al., 1991-1992). In fact, alcoholics are probably the largest population at risk for hypomagnesemia as well as a whole host of other metabolic derangements. When hypomagnesemia is detected, the appropriate course of action consists of addressing the underlying cause (if identifiable) and reversing the depleted state. www.geriatrictimes.com /g020208.html   (1937 words)

BioMed Central | Full text | Gitelman-like syndrome after cisplatin therapy: a case report and literature review Chronic hypokalemic metabolic alkalosis with hypomagnesemia and hypocalciuria is one of the rare complications associated with its use. Hypomagnesemia in GS is possibly explained by the observation that a complete block of NCCT by chronic thiazide treatment results in an increased rate of apoptosis in DCT cells in rats [2]. Hypomagnesemia occurs in 40–100% of patients and a reduction in GFR occurs in 20–30% of patients. www.biomedcentral.com /1471-2369/7/10   (1711 words)

eMedicine - Hypomagnesemia : Article by Anastasios K Konstantakos, MD   (Site not responding. Last check: 2007-10-03) Incidence of hypomagnesemia among people with alcohol dependence is approximately 25% and mainly is due to magnesium diuresis caused by alcohol. Hypomagnesemia may be associated with nonspecific ECG changes, including ST-segment depression, altered T waves, or loss of voltage. Although abnormally low levels of serum magnesium typically occur in adult patients hospitalized for prolonged periods, failure to include hypomagnesemia in the differential diagnosis for a similarly affected pediatric patient may be disastrous because hypomagnesemia is treated readily. www.emedicine.com /ped/topic1122.htm   (1885 words)

Magnesium: Minerals and Electrolytes: Merck Manual Home Edition The most common causes of hypomagnesemia are decreased dietary intake (due to starvation) and decreased intestinal absorption (malabsorption). Hypomagnesemia occurs frequently in people who consume large amounts of alcohol and in people who have protracted diarrhea. Hypomagnesemia can also be caused by increased excretion of magnesium by the kidneys. www.merck.com /mmhe/sec12/ch155/ch155g.html   (351 words)

What are the causes of hypomagnesemia? Journal of Family Practice - Find Articles   (Site not responding. Last check: 2007-10-03) Numerous studies agree that the prevalence of hypomagnesemia is much higher (10%-65%) in subpopulations defined by severity of illness (hospitalization, in intensive care unit [ICU] or pediatric ICU), increasing age (elderly/in nursing home), or specific diseases. In a group of 5100 consecutive patients (predominantly outpatient, middle-aged, and female) presenting to a diagnostic lab, the most common diagnoses associated with hypomagnesemia were diabetes (20% of cases) and diuretic use (14% of cases); however, other potential causes, including alcoholism, were not identified. The impact of hypomagnesemia is underestimated largely because clinicians fail to measure magnesium. www.findarticles.com /p/articles/mi_m0689/is_2_54/ai_n10301286   (765 words)

UpToDate Significance of hypomagnesemia in cardiovascular disease — Mild hypomagnesemia is a common electrolyte abnormality, particularly in the elderly who may have increased urinary magnesium losses due to diuretic therapy or interstitial renal disease. The data suggest that this might occur when hypomagnesemia occurs in the setting of an acute ischemic event, congestive heart failure, torsade de pointes, after cardiopulmonary bypass, or in the acutely ill patient in the intensive care unit. The mechanisms underlying the possible association between hypomagnesemia and arrhythmias is at present unknown. patients.uptodate.com /topic.asp?file=minmetab/7577   (535 words)

Hypomagnesemia - Wikipedia, the free encyclopedia Hypomagnesemia is an electrolyte disturbance in which there is an abnormally low level of magnesium in the blood.

Hypomagnesemia - New Treatments, January 2, 2007   (Site not responding. Last check: 2007-10-03) Hypomagnesemia is rare in healthy subjects because of the abundance of Mg in the food and water supply. Protein-calorie malnutrition, prolonged parenteral (Mg-free) fluid administration, and catabolic illness are common causes of hypomagnesemia. Hypomagnesemia is diagnosed when the serum Mg is less than 0.7-0.8 mMol/L. Symptoms of Mg deficiency occur when the serum Mg concentration is less than 0.5 mMol/L. 24-hour urine collection for magnesium is the first step in the evaluation of hypomagnesemia. www.ccspublishing.com /journals2a/hypomagnesemia.htm   (288 words)

Medications, Alcohol Consumption, and Magnesium: Ensuring Adequate Intake of Oral Magnesium Magnesium reabsorption in the thick ascending limb of the loop of Henle is decreased significantly by loop diuretics, and in the distal tubule by thiazide diuretics.

the Drug Monitor - Nasr Anaizi, PhD Hypomagnesemia is often asymptomatic, and when symptoms occur, there is a wide inter-individual variability in the nature and severity of the symptoms associated with similar degrees of hypomagnesemia. Also, hypomagnesemia is associated with target-tissue resistance to the actions of PTH. In addition to identifying and treating the underlying cause of hypomagnesemia, parenteral or oral Mg supplementation is often effective. www.thedrugmonitor.com /mg.html   (1254 words)

FDA Warns About Hypomagnesemia Due to Erbitux® Basically, Imclone is advising longer than a one-hour observation in patients with reactions and suggesting that patients should be monitored periodically for hypomagnesemia and accompanying hypocalcemia and hypokalemia during and following the completion of Erbitux therapy. The letter states that up to half the patients receiving Erbitux may have hypomagnesemia with 10-15% being severe.  These electrolyte abnormalities have apparently occurred days to months after starting Erbitux, and electrolyte replacement was required in some patients. [3] The authors of the paper observed profound fatigue and symptomatic hypocalcemia, and hypomagnesemia in a 34-year-old patient receiving Erbitux and Camptosar® (irinotecan) for colorectal cancer. professional.cancerconsultants.com /fda_news.aspx?id=35026   (462 words)

Magnesium Imbalance | Principal Health News Magnesium deficiency most often occurs in people who have been fed intravenously for a long time, whose diet doesn't contain enough magnesium, or who are unable to absorb and excrete the mineral properly. People who have hypomagnesemia usually experience loss of weight and appetite, bloating, and muscle pain, and they pass stools that have a high fat content. Neonatal hypomagnesemia can occur in premature babies and in infants who have genetic parathyroid disorders or who have had blood transfusions. www.principalhealthnews.com /topic/topic100587117   (773 words)

Magnesium and Seizures In contrast, recent randomized trials failed to demonstrate any major benefit from the routine use of low-dose aspirin in pregnancy, whereas a recent meta-analysis found calcium supplementation during pregnancy to be effective in reducing the risk of hypertension. Primary hypomagnesemia with secondary hypocalcemia (PHSH) is a rare type of hypocalcemic disorder which occurs in early infancy and is clinically characterized by recurrent tetany and/or convulsion. The normalization of her parathormone level during magnesium replenishment, along with the parathormone infusion data, suggests that this patient's hypomagnesemia was responsible for decreased parathormone synthesis and/or secretion, while target tissue responsiveness to parathormone was maintained. www.mdschoice.com /text/abstracts/Magnesium/magnsez.htm   (1865 words)
