    TLDR Skin, hair, and nail changes can help detect eating disorders early.
    The document examines the link between nutrient deficiencies and dermatologic signs in diagnosing eating disorders (EDs) like anorexia nervosa and bulimia nervosa. Nutritional deficiencies, such as zinc and iron, manifest in skin, hair, and nails, aiding early ED detection. Zinc deficiency can cause alopecia, while iron deficiency leads to hair thinning. Dermatologic signs, including lanugo-like hair growth and xerosis, often improve with nutritional rehabilitation. The paper emphasizes a multidisciplinary approach, integrating dermatological, psychiatric, and nutritional perspectives, to address the complex interplay of physical and psychological factors in EDs. Recognizing these signs is crucial for early diagnosis and effective management.
