Abstract
Magnesium is an intracellular cation. Renal excretion plays an important role in its homeostasis. Usually, magnesium deficit is caused by decreased gastrointestinal absorption, digestive losses or reduced renal tubular reabsorption. Magnesium deficit increased neuromuscular excitability and cause cardiac arrhythmias. Severe hypomagnesaemia can cause hypocalcemia and hypokalemia. On the other hand, hypermagnesemia is caused frequently by kidney failure and laxative abuse; nervous system activity and muscle contraction are diminished. Similarly, zinc deficiency is related, in many cases, with malabsorption and digestives losses. Zinc disorders are involved in immunological conditions and cicatrization disorders.
