SKIN SIGNS IN EATING DISORDERS
Eating
disorders are becoming an epidemic also in Europe, particularly among young
women. In eating disorders significant medical complications
occur in all of the primary human organ systems, including the skin
Cutaneous
manifestations are the expression of the medical consequences of starvation,
vomiting, abuse of drugs (such as laxatives and diuretics), and of psychiatric
morbidity. These manifestations include xerosis, lanugo-like body hair, telogen
effluvium, carotenoderma, acne, hyperpigmentation, seborrheic dermatitis,
acrocyanosis, perniosis, petechiae, livedo reticularis, interdigital intertrigo,
paronychia, generalized pruritus, acquired striae distensae, slower wound
healing, prurigo pigmentosa, edema, linear erythema craquele, acral coldness,
pellagra, scurvy, and acrodermatitis enteropathica. The most characteristic
cutaneous sign of vomiting is Russell's sign (knuckle calluses). Symptoms
arising from laxative or diuretic abuse include adverse reactions to drugs.
Symptoms arising from psychiatric morbidity (artefacta) include the consequences
of self-induced trauma.The role of the dermatologist in the management of eating
disorders is to make an early diagnosis of the 'hidden' signs of these disorders
in patients who tend to minimize or deny their disorder, and to avoid
over-treatment of conditions which are overemphasized by patients' distorted
perception of skin appearance. Even though skin signs of eating disorders
improve with weight gain, the dermatologist will be asked to treat the
dermatological conditions mentioned above.
