Anorexia nervosa (AN), a psychiatric disease characterized by chronic starvation, is complicated by severe bone loss (1), for which there is no effective, available therapy. Although bone resorption is markedly increased in these patients, estrogen is an ineffective anti-resorptive therapy in the setting of undernutrition. We hypothesized bisphosphonate(More)
Abnormalities in brain metabolism have not been consistently well localized in anorexia nervosa (AN), and effects of specific therapies on these functional abnormalities have not been studied. Androgen replacement therapy improves mood, well-being and cognitive function in men with androgen deficiency. We therefore hypothesized that women with AN and(More)
Anorexia nervosa (AN) is complicated by severe bone loss, cognitive function deficits, and a high prevalence of major depression. We hypothesized that bone formation would increase and depressive symptoms and spatial cognition would improve with short-term physiological testosterone administration. We randomized 33 women with AN and relative testosterone(More)
Ghrelin is a nutritionally regulated gut peptide that increases with fasting and chronic undernutrition and decreases with food intake. Sex steroid levels change in chronic undernutrition and might signal changes in ghrelin. At the same time, chronic undernutrition is characterized by low IGF-I that might also influence ghrelin, either directly or through(More)
Anorexia nervosa (AN) is characterized by low weight and self-imposed caloric restriction and leads to severe bone loss. Although amenorrhea due to acquired GnRH deficiency is nearly universal in AN, a subset of patients maintains menses despite low weight. The mechanisms underlying continued GnRH secretion despite low weight in these patients and the(More)
