Despite the peak of medical knowledge in the Abbasid period, the presence of famous medical families in the Abbasid court, translation and writing of medical works, attention to nutrition and health in the court of the Abbasid caliphs, the expectation of long life and quality was created for the Abbasid caliphs. However, all these possibilities were not used much by the caliphs, and if they had not been killed in the war, they would have died of disease, even at a young or middle age. This research is performed using library sources and descriptive-analytical method. According to the findings of this study, the urgent need of the Abbasid caliphs for "treatment" had caused physicians to be present in the court of the caliphs with great benefit of wealth and even power. Revelry, the unjustified lifestyle in having fun and spending a lot of time in the harem leads to the suffering from of some Abbasid caliphs in their age Young or untimely due to some incurable or incurable diseases that caused their premature death. Finally, among the 37 Abbasid caliphs, 30 of them were killed in internal or external wars and conflicts. The remaining number died of disease, despite the establishment of a coherent system of health and treatment and having all the medical facilities of their time. Therefore, despite the provision of medical facilities for the Abbasid caliphs, the wrong lifestyle and full of excesses in having fun has caused them to fall ill and eventually die.
