Cutaneous Manifestations of Eating Disorders

The 2002 document reviews dermatological signs associated with eating disorders such as anorexia nervosa, bulimia nervosa, and obesity, detailing 40 skin conditions that can arise from these disorders. It explains how nutritional deficiencies, self-harm behaviors, and physiological changes can lead to specific skin issues like pellagra, scurvy, erythema ab igne, Russell's sign, and acanthosis nigricans. The review also discusses skin problems in obese patients, including acne, infections, and mechanical changes like intertrigo and striae distensae. The treatment of these dermatological conditions often requires addressing the underlying eating disorder, and recognizing these signs can be crucial for early diagnosis and improved patient outcomes. The document underscores the importance of considering other potential causes for skin conditions, especially in patients with comorbidities.
