May someone donate a kidney knowing the donation may prevent them from fasting on Yom Kippur?
May someone donate a kidney knowing the donation may prevent them from fasting on Yom Kippur?
The source examines the meeting point between organ donation, self-sacrifice for another person and future observance of the Yom Kippur fast. It preserves the tension between the value of saving or helping another person and the donor's own medical and halakhic obligations, with strong medical and practical review required.
The practical force of the question lies in the boundary it draws. The Torah discussion must keep the source distinctions, conditions and competing values together rather than reducing the issue to a slogan or a one-line ruling. This localized text therefore stays within the exact canonical case and does not add new sources, factual claims or a broader practical ruling.
