These seem to be the equivalent medical terms, but I don't know if there is a nick name or a name covering the syndrome as a whole.

"The hard water syndrome is an acute, dialysis-induced
symptom complex characterized by nausea, vomiting, hypertension, muscular weakness, and a warm sensation to the skin.
Hypercalcemia and hypermagnesemia are prominent biochemical findings that depend on the amount of excessive divalent
cation in the dialysate as well as the duration of the dialysis
procedure. Thus, the quality of water should be carefully
evaluated before it is used for renal dialysis procedures."

The opposite hypokalcæmi og hypomagnesæmi is associated with alcohol consumption and dialysis.

Ved hæmodialyse af intoksikationspatienter, som oftest ikke er uræmiske, skal man være opmærksom på hypoglykæmi eller elektrolytforstyrrelser såsom hypofosfatæmi, hypokalæmi, hypokalcæmi og hypomagnesæmi.
