Hypokalemic Alkalosis in Liver Failure

mikejonathan: did you look that up? can you give the reference?

Another possible explanation: liver failure leads to a decreases protein/albumin synthesis, the plasma becomes hypooncotic, fluid is shifted from intra- to extravascular (-> ascites, low blood pressure, etc). A compensatory mechanism is a increased renin activity, leading to aldosterone production. Hyperaldosteronism leads to hypokalemia and hypernatremia. The strong ion difference (SID), mainly determined by Na and Cl, to lesser extends by K and HCO3, increases -> alkalosis! (as Cl- is not regulated by aldosterone).
