In this article, the other disturbances in appetite, including Joo-al-Kalb, Joo-al-Baqar, Joo-al-Qashye and Fessad-e- Shahvat are also discussed briefly.

Materials & Methods: We searched the databases PubMed, ISI web of science , IranMedex and SID with  theses keywords, Anorexia, Dysorexia, Traditional medicine and Arzani, further than the book Mizan-al-Teb as the main source of the article.

Results: Anorexia and dysorexia are two common problems in all age groups. Anorexia nervosa is a common problem in young females. Calorie intake of  the patients with anorexia nervosa is less than their daily requirements.
