Hypokalemia in patients with anorexia nervosa during refeeding is associated with binge–purge behavior, lower body mass index, and hypoalbuminemia

Abstract Background Hypokalemia is frequently found in patients with anorexia nervosa and sometimes leads to life-threatening conditions. Although their serum potassium levels are considered further decrease during refeeding, no previous studies have addressed actual changes the potential mechanisms underlying hypokalemia refeeding period of nervosa. In this study, we investigated factors associated Methods We recruited 52 independent from 89 admissions (body mass index, 13.0 ± 3.3) psychiatry unit Ashikaga Red Cross Hospital April 2003 March 2018 analyzed at admission. Of admissions, 66 > 1-week hospitalization were determine lowest period. these multiple linear regression analysis explanatory variables, including data upon admission treatment-related indicators. Results The initial level 3.6 0.9 mg/dl decreased 3.1 0.7 nadir hypophosphatemia, which was observed an average 2.5 days after A lower a body hypoalbuminemia, binge–purge behavior. Similar results obtained when included restrictive or types as well patient group. Conclusions Lower behavior might be used indicators guide clinical approaches for controlling refeeding.
