Magnesium balance
Magnesium
- Normal levels 0.7 - 1.0 mmol/l
- Function - co-factor in enzymes (phosphate transfer), CNS, neuromuscular systems
- High magnesium levels prevent calcium cellular uptake
- Homeostasis maintained by kidney - freely filtered at glomerulus, reabsorbed at PCT and TALLOH
Causes of Hypomagnaesemia
- Gut loss - diarrhoea / IBD, malnutrition
- Renal loss - diuretics
- Alcoholism
