Refeeding hypophosphatemia remains a serious and common complication during the early phases of nutritional rehabilitation and weight restoration for patients with anorexia nervosa. Typically, the risk of refeeding hypophosphatemia diminishes after the first 1-2 weeks of the refeeding process and thus, frequent monitoring serum phosphorus levels becomes less important as refeeding proceeds. Herein, we describe a case of persistent recurrent hypophosphatemia in a male-to-female transgender patient with severe anorexia nervosa. As transgender patients become increasingly seen in the realm of eating disorders, it is worth noting this phenomenon to mitigate adverse events.
