Anyone know the mechanism??
This is all UpToDate has to say:Bump, I'd like to know too.
Magnesium apparently plays an inhibitory role on renal potassium secretion by deactivating ROMK channels. Mg below basal levels relieves this inhibition. So in short, low magnesium promotes renal potassium wasting.I know this may seem like a stupid question Phloston, but why does hypomagnesemia cause hypok?

Btw, how does hypomagnesemia exactly cause hypocalcemia?
I looked it up and it seems like hypomagnesmia causes less synthesis/secretion of PTH --> less reabsorption of Ca in the DCT.
Is this the only mechanism?
Also how does hypocalcemia exactly cause TdP?
Thank you so much!
