Hypermagnesemia overview

Overview
Hypermagnesemia is an electrolyte disturbance in which there is an abnormally elevated level of magnesium in the blood. Usually this results in excess of magnesium in the body.
Pathophysiology
Hypermagnesemia occurs rarely because the kidney is very effective in excreting excess magnesium. It usually develops only in people with kidney failure who are given magnesium salts or who take drugs that contain magnesium (e.g. some antacids and laxatives). It is usually concurrent with hypercalcemia and/or hyperkalemia.
Diagnosis
History and Symptoms
Symptoms of hypermagnesemia include weakness, nausea, vomiting and impaired breathing.
