MAGNESIUM IMBALANCE
Slide2Slide3DEFINITION
Hypermagnesemia is an electrolyte disorder in which there is a high level of magnesium in the blood.
Hypermagnesemia is a serum magnesium concentration > 2.6 mg/dL (> 1.05 mmol/L)
Slide4CAUSES
Most cases of hypermagnesemia occur in people who have kidney failure. Hypermagnesemia occurs because the process that keeps the levels of magnesium in the body at normal levels does not work properly in people with kidney dysfunction and end-stage liver disease.
Slide5Other causes of hypermagnesemia include:
lithium therapy
hypothyroidism
Addison’s disease
milk-alkali syndrome
drugs containing magnesium, such as some laxatives and antacids
familial hypocalciuric hypercalcemia
Slide6SYMPTOMS
nausea
vomiting
neurological impairment
abnormally low
blood pressure
(hypotension)
flushing
headache
Slide7MANAGEMENT
The first step in treating hypermagnesemia is identifying and stopping the source of extra magnesium
An intravenous (IV)
calcium
supply is then used to reduce symptoms such as impaired breathing, irregular heartbeat, and
hypotension
, as well as the neurological impact.
Slide8Intravenous calcium, diuretics, or water pills may also be used to help the body get rid of excess magnesium.
People with renal dysfunction or those who have had a severe magnesium overdose may require dialysis if they are experiencing kidney failure, or if magnesium levels are still rising after treatment.
Slide9Slide10DEFINITION
Hypomagnesemia is serum magnesium concentration < 1.8 mg/dL (< 0.70 mmol/L)
Slide11CAUSES
Slide12SYMPTOMS
Early signs of low magnesium include:
nausea
vomiting
weakness
decreased appetite
Slide13As magnesium deficiency worsens, symptoms may include:
numbness
tingling
muscle cramps
seizures
muscle spasticity
personality changes
abnormal heart rhythms
