There is still no consensus on the definition of these disorders, which cover a wide range of severity. Affected adolescents often suffer from physical and psychological problems owing to co-morbidity or as a consequence of their eating patterns: chronic constipation, dyspeptic symptoms, nausea, abdominal pain, fatigue, headaches, hypotension, menstrual dysfunction as well as dysthymia, depressive and anxiety disorders, or substance misuse and abuse. In comparison with those who are unaffected, adolescents with partial ED are at higher risk of evolving into full ED. However, most of them evolve into spontaneous remission. Adolescents with partial ED engaged, over a period of several months, in potentially unhealthy weight-control practices, suffering from intense fear of gaining weight and a disturbed body weight/image should be offered therapeutic support.
Future research should focus on the exact delineation of various subtypes of clinical presentations in partial ED and on evidence-based treatment and follow-up of these various situations.
