Nephsap review: Fluids Electrolytes

Interesting thing we learned at our Nephsap about why hypomagnesemia causing hypokalemia
1. Intracellular Mg has inhibitory effects on the K secretion of ROMK channels in the distal nephron.

3. Also Low Mg can lead to increase distal Na delivery and increased aldo as well and K excretion increases.
