Reply to comment by ThinkBlueCountOneTwo in when a limb gets amputated, how do they stop the flow of blood? by EnchantedCatto

Depends on the size of amputation. A pinky toe? No different. Both legs at the hip? Yeah they can run into some cardiac issues which there are theories about why. I've attached a very topical paper on this if you'd like to read. https://pubmed.ncbi.nlm.nih.gov/18281705/

In a lot of cases the reason they got an amputation was decreased blood flow (diabetics) so they likely just normalize in that case lol

What is the part about the “patients’ devious behavior” referring to?

in this case deviant behavior means alcohol consumption or eating disorders.

Imaging if you were able to drink a whole 26oz bottle of vodka without issue, and then you then had half of your body removed. attempting to drink the same amount would be like drinking double what you had been, since you have half the body left to absorb and buffer the effects of alcohol. Could be a recipe for death. Same as with food.. with half a body, you don't need to eat as much, and so you could literally eat yourself to death.

Could they... drain them a bit? Blood is made in the bones, and if you got a few fewer bones, technically you could have slightly less to pass around lol

blood isn't made at a constant rate but as needed, otherwise donating blood would permanently lower your blood pressure

it is not so much the amount of blood that is the problem but that the heart is used to pump against a given flow resistance and that resistance changes with the number of reduced "consumers". It is a little like with the electrical grid, when large consumers suddenly go offline/online, the power plants have to adjust their generation to not cause a systemic failure.
