Magnesium Deficiency in Cats




Treatment depends on the underlying cause of the abnormality and the severity of the hypomagnesemia. Because severe hypomagnesemia can be fatal, prompt and appropriate treatment is essential. Mild hypomagnesemia may resolve with treatment of the underlying disorder; however, if hypomagnesemia is severe, intensive care will be needed.


If digoxin is being prescribed, its use will have to be discontinued, if possible, until the hypomagnesemia has been resolved, and diuretics will need to be used with caution, or another form of fluid removal prescribed. In addition, it must be kept in mind that hpermagnesemia – too much magnesium in the body – is possible with overzealous treatment.


Living and Management


Initially, your veterinarian will want to check your cat's magnesium and calcium concentrations on a daily basis. During magnesium infusions, your doctor will also want to administer an ECG continuously to make sure that your cat's heart is staying within its normal rhythm.
