There is no definitive answer at this point. It has only been in the past ten years that the health care field in Taiwan has seen resources devoted to research on anorexia. The problem is that, faced with a patient with drastic but unexplained weight loss, internists typically look only at physiological disorders when seeking a diagnosis, but cannot discern the true cause: the patient's refusal to eat.
台灣近 10 年才開始有醫界投入厭食症研究，只是，面對無故消瘦不止的病患，內科醫師往往只在生理的病灶上找答案，卻因檢查不出病因而作罷，殊不知問題出在患者根本不願意吃東西。
