Physiology of Potassium Handling. Potassium (K+) is the most abundant cation in the body. About 90% of total body potassium is intracellular and 10% is in extracellular fluid, of which less than 1% is composed of plasma.
Little potassium is excreted in the stool under normal conditions because of a low stool volume and a low stool potassium concentration. Conditions that increase stool potassium concentration, such as chronic renal failure and hyperkalemia, or stool volume, such as diarrhea, increase fecal potassium excretion.
