Rates of eating disorders are higher in patients with type 1 and type 2 diabetes than in the general population. Types of eating disorders include anorexia; bulimia; binge-eating disorder; subclinical eating disorders; and an eating disorder unique to type 1 diabetes, intentionally restricting insulin doses as a calorie purge—often referred to by laypeople as “diabulimia.” Women with diabetes and eating disorders (including disordered eating behaviors) have significantly elevated blood glucose ranges, higher rates of hospitalization, higher rates of diabetes complications, and, in some cases, higher mortality rates. This chapter discusses risk factors, presentation, and identification of eating disorders within the diabetes population. Specific recommendations are given for this difficult-to-treat population, including the need for an expanded treatment team as well as the need to establish mutually agreed upon and incremental diabetes management goals.
