Ramadan fasting and transplantation: Current knowledge and what we still need to know

Ramadan fasting is one of the most appreciated Islamic rituals in Islamic culture. Although non-healthy as well as weak people are allowed not to fast in this month, some trans­plant recipient patients are willing to fast but are concerned about adverse effects on their health. Due to answering this question, a number of studies have been conducted. In this literature review we review the existing data on this issue and attempt to reach to a conclusion on what we know and what we still need to know.
