Low Magnesium Question

J.D. had low Potassium and we've got that up into normal range, and now his Magnesium is low.
Does anyone have experience with this?

Spec fPL 10.0 (Fasting) 0.1 - 3.5 ug/L High
Comments: > or = 5.4 ug/L
Serum Spec fPL concentration is consistent with pancreatitis. The cat most likely has pancreatitis. Consider investigating for risk factors and concurrent diseases (e.g. IBD, Cholangitis, Hepatic Lipidosis, Diabetes Mellitus). Periodic monitoring of Spec fPL may help assess response to therapy.
