Refractory hypokalemia in presence of hypomagnesemia


Q; Why potassium cannot be fixed if hypomagnesemia remains uncorrected?

A; Hypomagnesemia causes kidney to continue to loose potassium, thats why hypokalemia cannot be fixed if hypomagnesemia remains uncorrected. It can be confirmed with TTKG calculation.
