Abstract
We discuss a case series that explores the presentation and diagnostic challenges of three elderly male patients with hypomagnesemia. This series highlights the association between hypomagnesemia and hypocalcemia, both of which contribute to neurological symptoms. Proton-pump inhibitors, when taken for a long duration, are known to cause hypomagnesemia. This series also emphasizes the reversible neurological syndromes in patients with hypomagnesemia due to prolonged pantoprazole intake.
