Watters A, Johnson RJ, Bauschka M, et al. - Serum uric acid (UA) levels were examined in patients with extreme forms of eating disorders, at admission and discharge, following weeks of nutritional rehabilitation and weight restoration.

• A total of 160 patients diagnosed with anorexia nervosa restricting subtype (AN-R), AN binge-purge subtype (AN-BP), or avoidant restrictive food intake disorder (ARFID) were included in this observational study.

• Most patients with severe AN-R tended to show serum UA levels in the low-normal range, but not this was not evident in AN-BP.

• However, nutritional intake and weight gain resulted in an increase in levels.

• Checking UA levels on admission may be clinically valuable for patients with eating disorders.
