Why would there be hyperkalemia if total body potassium is decreased in DKA?

drdoom  super high blood glucose; super high glucose spillage into urine; lots of peeing = volume depleted (“osmotic diuresis”) +  
alphatnf  because insulin normally stimulates Na/K ATPase, which sequesters K inside cell. lack of insulin means that there will be more K outside of the cell causing hyperkalemia. however, you are still total body K depleted due to osmotic diuresis. so the hyperkalemia is mainly due to a shift of K from the intracellular (where the vast majority of your K is inside your body is) to the extracellular space. +
