Our body is an incredible machine, but it's also a bit of a mystery. Despite spending our entire lives in this amazing, complex vessel, we often know surprisingly little about it. However, while it might be thrilling to discover fun facts about the human body, there are also some unsettling truths you might prefer to ignore.
When u/Beneficial_Cry2061 asked on Reddit, "What is a disturbing medical fact that not many people know?" the responses started pouring in. People shared some truly unsettling facts that might just make you squirm. Dive in and discover these strange realities of the bodies we live in.

Cold sores can cause inflammation of your brain. It’s called herpetic encephalitis and is likely to cause permanent brain damage even with treatment. It can also be caused by shingles, so getting the shingles vaccine is more important than you think.

When you have surgery and your organs have to be scooped out to access something else, they don’t put them back where they were. They just kinda put it all back in and our organs just shift back to where they were. I learned this fact when I went to stand up after having a csection.

Not sure how unknown it is, but at any given time without warning your uterus can just fall out. And unless it’s fully dangling outside of you, the doctors will just tell you to try to shove it back in there.

Can I give two? They’re disturbing to me.
1)The prevalence of middle ear infections in children from 0-6 y/o.
Please don’t ignore this. Have hearing tested annually, the impact on schooling, speech, milestones etc. is not to be taken lightly.
2) Untreated hearing losses, under stimulated brain possibly leading to accelerated risks of early onset memory loss, dementia etc. The worse the hearing the higher the risk. Just get your hearing tested annually, you’re never to young for a hearing loss man.

Oxygen poisoning is a thing. Too much O2 in your body can kill you.
But don't worry, you won't die from breathing too hard. It's mostly an issue for divers and other people who breathe pressurized breathing gases.

Not a human example (probably), but sometimes cows, goats and other animals get pregnant but instead of giving birth to a normal lamb/kid/calf it gives birth to an *"amorphous globosus"*, a spherical mass of flesh with an outer layer of skin with hair or fur, and the inside a jumbled mess of guts and tissues and sometimes teeth. They never have brains or spinal cords though, so they're always stillborn and nonviable.

Everyone who's had to deal with a brand new baby's had to deal with it, but a baby's first poop (meconium) is very thick and sticky and hard to wipe off. What most people don't know is what it's made of.
Around halfway through a pregnancy, a fetus develops hair called lanugo all over their body. They shed most to all of it before they're full term. That hair is shed directly into the amniotic fluid, which is then ingested by the fetus, and (hopefully) stays in their intestines until birth or right after.
So, basically, fetuses eat their own hair, and since amniotic fluid is swallowed and excreted, you could say they're swimming in their own pee.
Also, chainsaws were invented for childbirth.

Some hospitals allow medical students to practice on patients who are under anesthesia. Without the patient's knowledge/active consent.
It is completely f****d up. They hide technical consent in overly broad terminology in the papers you sign when you go in for an operation.
They argue that they do it this way because it is hard to get volunteers for students to practice very invasive internal exams.

The eyelash mite lives mainly on the human eyelash and is an 8 legged parasite that eats skin and oil. They stay hidden in the hair follicles during the day and emerge at night to eat, lay eggs and excrete waste. And that is why you should wash your face in the morning.

Prions.
Edit- prions are misfolded proteins that cause other proteins to misfold in your body and it causes cell death. They affect the brain and aren't curable. They are also extremely hard to destroy. A few prion diseases are:
Mad Cow Disease
Kuru
Creutzfeldt–Jakob disease
Fatal Familial Insomnia (nightmare fuel)
Chronic Wasting Disease.

When you get a kidney transplant, unless your original kidneys are diseased, they just lEAVE THE OLD ONES IN THERE. OLD DEAD KIDNEYS JUST CHILLING
also- fallopian tubes are not connected to ovaries. they just float in the general direction of the ovaries and do their best to vacuum up eggs as they get popped out (kind of like a pimple bursting) out of ovary pores? so the eggs just get popped wherever and you gotta cross your toes and hope your weird little vacuum tubes are aiming right that day???

Humans have both light meat and dark meat due to type 1A and type 2B muscle fibers. However, humans are lean and not very calorie dense, so if you're already starving cannibalism doesn't do much good.

In canada and the states, doctors and residents are allowed to perform gynaecological exams on women under general anaesthetic, in order to provide students and residents with experience performing pelvic exams. this is typically not disclosed to the patient, and is justified as being part of receiving treatment at a teaching hospital.

Lots of things we know about resuscitation, trauma surgery, emergency medicine etc, were learned through gruesome vivisective experiments on WWII prisoners of war. Basically, every life saved now was paid for by a PoW tortured to death in a camp.
