Medicine is unique in that every radical advance is simultaneously exciting and terrifying. When they tell you that they may be able to repair your liver by implanting one grown in a sheep, you'll be half tempted to say, "Nah, I'm just gonna try to ride this one out."
Those same mixed emotions surely run through every patient who hears their doctor suggest ...
5Shoving Human Feces Up Your Nose
So, you've got some stomach problems. Maybe you have inflammatory bowel disease, irritable bowel syndrome or chronic constipation -- whatever, there's no need for us to make jokes about "too many enchiladas" here. Gut problems are no laughing matter. Well, until your doctor looks you dead in the eye and in a somber tone says, "I'm afraid that you're going to need a shit transplant. And no, this is not a euphemism."
"Eat shit and live."
How in the hell could that possibly be a real thing? Well, it has to do with bacteria. As much as we think of bacteria as being the stuff that makes us sick (isn't that why people use smelly antibacterial hand lotions all the time?), your body is actually full of the stuff. Especially in the intestines, there are all sorts of "natural human flora" that make normal food digestion possible.
But, if the bacteria go wrong, then digestion goes wrong. Which means the reverse is true: You can fix a lot of intestinal problems by fixing the bacteria. So for a while, science has known that isolated bacteria from human feces could be used to treat gastrointestinal disorders. But then finally somebody said, "Why not just get somebody's healthy shits and cram it all into the sick person? Then we'd know they have the right bacteria, right?"
And then they went and had a party to celebrate, because scientists are different from us.
They call it "fecal bacteriotherapy" (also known as a fecal transplant or transfusion), and we know what you're thinking: "So does this mean the donor has to come to the hospital and poop into my butt? Or do they have some kind of hose that shoves the poop into my butt?" It's neither. The human digestive tract runs one-way. If they're going to cram donor turds into you, it has to go in the other end.
This is why a lot of porn stars have incredibly healthy intestines.
Luckily, to avoid having to eat poop, they have figured out that they can simply run a tube through your nose, down your throat, through your stomach and into your duodenum. Then they have somebody shit into it. Or maybe they have a bag of shit sitting there already, we're not reading any more about this.
4Removing Half of Your Brain
Seizures and epilepsy affect an unacceptably high portion of the population. There is medication, of course, and other treatments that may or may not work, or may have varying awful side effects.
And, when things get really bad, you're probably willing to listen to any options. And that's good, because there's a chance your doctor will stroke his chin and say, "Well, all of the seizures are coming from the left side of your brain. Probably best just to take that sucker out."
"No, this jar is for the important brains. Yours will go into that bowl with a bone on it."
Understanding why they would remove half of your brain to stop seizures involves understanding a bit about what a seizure is. It's basically a sudden surge of electrical activity in the brain, and the problem is that it usually originates in one spot and then radiates across the rest (kind of the way a short circuit can send a jolt across anything made of metal that's touching it). So maybe it makes sense that some primitive doctor way back when decided to just hack that half of the brain out. The shocking part is that A) it worked, B) they still do it and C) you can totally survive it.
They do have to stick another elbow onto your brainless side to balance you out, though.
The procedure is called a hemispherectomy, and you can absolutely live a normal life after the half-brain removal, especially if you have it done as a child, since the brain is still growing, and the remaining half can adapt to carry the load. Of course there are tons of risks, and it is a last resort (only considered when "the alternatives are worse"), but more than 75 percent of patients are completely or nearly completely seizure-free after that.
Wait, so once it's done, the other half of your skull is just empty space? What keeps the remaining half of your brain from sliding around in there? Well, like any empty pocket in your body, it eventually fills with fluid. Though, yeah, there have been cases of patients' remaining half-brains sliding around and causing problems.
You'd think they'd at least stuff a couple of hand towels in there.
Of course, there are less severe options, such as corpus callosotomy, where they merely go in and cut your brain in half, but leave both halves in your skull. That way you might still get seizures, but they can't spread to the rest of the brain because, well, it's completely cut off. Science!
You wouldn't leave us with an independently murderous limb, though, would you, science? S-science?
