Causes of Hypokalemia - Differential Diagnosis Algorithm

Increased Loss 

 - Increased GI Loss

 - Increased Urinary Loss

Decreased Intake (rare)

Transcellular Shift Into Cells

 - Alkalemia

 - Increased Cell Production

 - Stimulation of Na/K-ATPase which imports K+ into cells: Insulin, Beta-Agonist

 - Refeeding Syndrome
