II. Definition

  1. Hypokalemia with Urine Potassium < 20 meq/day

  1. Diarrhea
  2. Amphotericin
  3. Diabetic Ketoacidosis
  4. Laxative abuse
  5. Intestinal or biliary fistula
  6. Ureterostomy
  7. Toluene

V. Causes: Metabolic Alkalosis and Hypokalemia

  1. Gastrointestinal loss (Consider Bulimia)
