I am pregnant. Do I have to fast on Yom Kippur?
Pregnant women must fast on Yom Kippur.
Pregnant women who are high risk need to discuss with a Rov whether they should fast or not.
Nausea, tiredness, or weakness are not reasons to break the fast as they are natural symptoms of pregnancy and do not indicate any high risk.
If a pregnant woman experiences dizziness which is continuously increasing, the beginning of fainting, or she sees flickering circles or black in her eyes, she should drink immediately as necessary.
If she is approaching birth – even if she is not experiencing signs of labor yet – and is extremely weak, she must drink shiurim, so that she have the strength to give birth.
A woman in labor is permitted to eat and drink. However, whether it’s advisable medically to eat and drink during labor is a medical debate. Every individual should consult their own doctor.
