Other factors associated with a high incidence of hypokalemia include the following:

  • Eating disorders (incidence of 4.6-19.7% in an outpatient setting [40, 41] )

  • AIDS (23.1% of hospitalized patients) [42]

  • Alcoholism (incidence reportedly as high as 12.6% [43] in the inpatient setting), likely from a hypomagnesemia-induced decrease in tubular reabsorption of potassium

  • Bariatric surgery [44]
