Any small amount of uterine blood at all that leaves the uterus is enough. There is no minimum. (See Gemara Niddah 40a; Yoreh Deah 183:1, with Shach:3) "...even if she only saw a drop of blood the size of a mustard seed; she must observe seven clean days for it." On the one hand, there is no amount mentioned by Chazal, that limits the exception on colored ...

According to sefer Sheva Mitzvot Hashem, (Vol II, helek 5, 9:1), a tubal ligation is permitted for bnot noach. And further says: that even more than this could be done for reasons of safety or health issues.

The Rambam didn't know a successful kidney removal was possible. He was working under the assumption that anyone whose kidney was removed would necessarily die soon. The Rambam's source is Bechorot 7:7, which discusses which blemishes render an animal unfit for eating, but not a person for priestly duties: אלו כשרין באדם, ופסולין בבהמה: אותו ואת בנו, ...

Halakha does not distinguish between "medicine" and "supplements" with respect to the laws of kashrus. There is a prohibition on eating non-kosher food, but certain considerations cause that prohibition to be overridden. It seems to me that kosher options are always preferable to non-kosher options when all else is equal. However, there are three ...

That's a dispute between Tane Kamah and R' Yehuda regarding the prohibition of castrating in Tosefta Makos 4 4: המסרס את האדם ואת הבהמה ואת החיה ואת העוף, בין גדולים בין קטנים, בין זכרים ובין נקבות – הרי זה חייב (מלקות). רבי יהודה אומר: מסרס את הזכרים – חייב, ואת הנקבות – פטור (מהתורה, אבל אסור מדרבנן). (Tane Kame says removing woman's ...

R David Sperling (here) writes it seems to him that taking these medicines is permitted because Firstly, someone who has started on a course of pills before Shabbat may continue to take them even on Shabbat (see Shmirat Shabbat KeHilchatah, 34, 17). Secondly, it is not clear that someone with ADHD is considered at all "sick" or "under the ...

SA Yoreh Deah 55:1 (transl: Nishmat Avraham) One may not receive treatment from an idolater for any injury or disease which is so dangerous that Shabbat laws could be set aside for the purpose. However, if he is a recognized specialist, it is permitted. If he is not, one may not receive treatment from him even if there is a possibility that the ...

Since you are specifically interested in the writings of R Moshe Feinstein on the topic, I recommend Responsa of Rav Moshe Feinstein: Care of the Critically Ill by R Moshe David Tendler which translates key responsa on the topic. See in particular Igrot Moshe CM II:73 regarding short-term prolongation of life in cases where further improvement is not ...

Regarding the first issue, I think a key point that has to be noted is the precise wording used by Tosafos, particularly at the end. When discussing ailments that are directly God-inflicted, Tosafos does not say you might think that healing them is contravening the decree of the king. Rather, Tosafos says that you might think that healing them appears like ...

The Shulchan Aruch 141:1 writes that the baal koreh must stand. Even leaning on a wall is assur unless one is a baal basar (overweight). The Pri Chadash holds that if he did sit then they are yotzei b'deved. Rav Yitzchak Abadi 1:53 has a teshuva that one does not need to stand during laining and brings as a proof the fact that only the baal koreh needs to. ...

I occasionally daven in a nursing home. One of the patients has an amputated leg. He lains (and is frequently Shaliach Tzibur ) from his wheelchair. The rav permits this. @Sam referred to O.C. 141:1 which states that the ba'al Koreh must stand. However, see Mishnah Berurah commentary #4 which states that someone who is ill may lean a bit. I have to look ...

If you are speaking of general anesthesia, R Moshe Chaim Friedman answers here for babies General anesthesia, which is putting the baby to sleep for the b’ris, is simply not done, because virtually all practitioners would agree that it is not worth taking the greater risk of general anesthesia for such a simple procedure. For children younger than ...

Rav Chaim Kanievsky(Doleh Umaskeh pg.258) was asked if one ate dairy during 6 hours of meat consumption should they throw it up . He answered that one does not have to throw up. Footnote 18 mentions that even if a person ate issur mamash like it says in Shailos Rav pg.25 that even if one ate a sheretz still they do not have to throw up. Rav Chaim (Derech ...

The Mishnah in Horiyos (13a) sets out an order of priorities for different situations. One of the situations presented, is regarding saving a person's life. Let's say, that I can save only ONE person in a group of people, whose lives are ALL in danger, which one should I choose to save? Since a kidney donation is a life saving act, I suggest that the order ...

R' Gil Student in a TorahMusings.com article titled "Medicine on Shabbos" says that your question is "an excellent question that the greatest halakhic authorities of recent times have asked" and cites sources who proceed to offer two approaches: 1) Maybe it should be permissible today! R' Avraham Chaim Na’eh (Ketzos Ha-Shulchan 134 n. 7.2) considers the ...

As your EDIT points out, many poskim rule that one who takes medicine daily may continue to do so on Shabbos, while R' Moshe and others disagree. R' Howard Jachter has an article titled "Taking Medicine on Shabbos part II" where he neatly spells out this machlokes: "Taking Medicine Over a Period of Time" Shemirat Shabbat Kehilchata (34:note 76) ...

In truth the sick must trust in God to heal him, and going to a doctor would sour the sick’s faith in God. God gives the doctor permission [through writing the verse] to heal the sick, justifying the sick and their lack of belief. Peninim Mishulchan Hagra, p. 161 שמעתי מהחסיד דקהלתנו שיש לדקדק מש שאמרו רשות לרופא לרפאות ולא רשות לחולה. רק באמת חיוב ...

Rabbi Zamir Cohen in his book the discusses Auras as a scientific fact. Which would assume that halacha permits it.
