WHAT IS IT?
Hypomagnesemia refers to low levels of magnesium within the serum (< 1.8 mg/dL).
WHAT CAUSES IT?
Possible causes of this condition can fall into several categories (outlined below):
- Compromised magnesium intake: poor dietary intake, intestinal malabsorption, inadequate magnesium supplementation in a care setting
- Excessive magnesium loss: excessive loss in GI system (i.e. diarrhea), excessive urinary losses (i.e. diuretics)
- Other medical conditions: hyperaldosteronism, hypercalcemia, acute pancreatitis, burned patients
Patient Issues/(Chief Complaints):
Detection On Medical Workup:
- Finding from a serum magnesium study
WHAT ARE IMPORTANT ELEMENTS OF THE MEDICAL HISTORY?
WHAT ARE IMPORTANT FEATURES OF THE PHYSICAL EXAM?
- Increased deep tendon reflexes
- Positive Chvostek sign
CLINICAL WORKUP: SERUM STUDIES
Serum magnesium: this serum study will help aid in the diagnosis.
WHAT IS OUR THRESHOLD FOR DIAGNOSIS?
A serum magnesium of < 1.8 mg/dL is the threshold for diagnosis hypomagnesemia
