Question: What are the usual clinical manifestations of hyper-magnesemia?
Answer: The cited reference points out that the clinical manifestations of hyper-magnesemia are “concentration dependent” and that “They range from mild nausea and vomiting to absence of deep tendon reflexes. At higher levels, paralysis of voluntary muscles can occur. This could result in respiratory compromise by affecting diaphragmatic muscles… Higher levels cause conduction defects and hypotension” (Kala J and Abudayyeh A. Magnesium: An overlooked electrolyte. 2017 J Emerg Med 52(5): 741-743)
