Hyperthyroidism during refeeding in anorexia nervosa




We report the second case of hyperthyroidism emerging during refeeding of a severely malnourished patient with Anorexia Nervosa (AN).


Available patient records and biochemical data were evaluated. Previous case reports of hyperthyroidism in eating disorders were reviewed.


Refeeding can be associated with the onset of hyperthyroidism in patients with AN. AN and hyperthyroidism share a number of symptoms which can make identification of hyperthyroidism difficult. Lack of weight gain because of hyperthyroidism may be interpreted as noncompliance with refeeding treatment. The report shows that not taking antithyroid treatment can be employed as a method of weight control, highlighting the importance of extra consideration regarding treatment regimen and adequate support with medication compliance. © 2011 by Wiley Periodicals, Inc.
