ubiquitin,
“If it was black and white ie Mothers life is at risk then halacha is Faaaaaar more “lenient” than halacha.”
I’m assuming your second “halacha” was intended to read “medical opinion.”
“I face this often when patients ask if they should fast yom kippur, I tell them if you want a heter you are better off talking to a Rav. Especially pregnant patients (though I’m not an OB ) for a healthy woman with a normal pregnancy there is (generally) no medical reason not to fast , worst case she goes into pre-term labor. no big deal.””
I have witnessed different medical opinions, and have never heard any doctor say that it’s ok for a pregnant woman to go 26 hours without water. And since we’ve had this discussion before, I’ll just save time and anticipate your response: “I asked my OB friend, and she said puk chazi.” But that doesn’t work, because apparently the rabbis give plenty of heterim, so how can we really see the impacts of 26 hours sans food and water when the weaker pregnant women are fasting in measures?
