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.

The truth about HeLa cells. These cells grow and divide constantly and are used in all sorts of medical research to discover cures for cancer and other diseases. They were originally harvested from a woman named Henrietta Lacks who had cervical cancer that was fatal. She died in 1951. Her family didn’t know that her cells were even being used until recently. These cells were basically stolen from Henrietta by a doctor and he made millions from them, and Henrietta’s family never knew. Once they found out, they finally settled with a biotech company for an undisclosed amount. This woman has basically saved so many of us, and we all owe her so much.

What made the cells from Henrietta Lacks so scientifically significant is that they keep growing & dividing indefinitely. In 1952, this was a first, no other cells they harvested from other women did this. They are truly a scientific wonder & have been used in developing treatments for polio, cancers, HIV/AIDS & even the Covid vaccine. This woman needs to be celebrated & taught in every science class. To demean her down to just HeLa cells is a travesty that all of humanity needs to change. Many of us simply wouldn't be here if it wasn't for her cells.

A fertilised egg can fail to develop normally and grow into a malignant tumor. It's called a molar pregnancy and I'd be very interested in what the "life begins at conception" crowd has to say about it.

The health of your teeth, or lack thereof, can cause heart disease. The bacteria that infect the gums and cause gingivitis and periodontitis also travel to blood vessels elsewhere in the body, where they cause blood vessel inflammation and damage.
If you are diabetic, and don't know it--or do, but have problems controlling your sugars, it can severely harm your teeth. On the flip side? Having bad teeth can severely affect your blood glucose as a diabetic. It can become a s****y cycle.
And yes--mentioned earlier, but if you get an infected tooth, that infection can travel to the brain or blood very fast.
And yet, teeth are still considered "luxury bones," with maintenance, cleaning, and dental care hardly ever being covered by insurance.

Chest compressions are violent. Just let your 91 year old grandma go.

A study by Johns Hopkins in 2016 cited that medical errors are probably the 3rd leading cause of death in the USA, following heart disease and cancer.
Errors were: Wrong Diagnosis. Incorrect dosage or wrong meds. Surgery errors and the biggest, poor communication between staff.
It is also thought that this study is also correct in the UK and EU.
LeMurierBonjour 2 months ago
Wrong diagnosis and poor communication is really unacceptable in this age of scientific and communication advancement. The problem lies with the systems and processes in place that have to be navigated to get a patient in front of the right specialist. The NHS in the UK is terrible for this. And I have no idea what the point of a GP (general practitioner) is anymore.
#9
Not necessarily a medical fact, but a reality check: Doctors don't have everything figured out, they are just human like the rest of us. Just like how us software developers search Google to troubleshoot something when we are stuck, they do too. Shows like Dr. House portray doctors as this infallible walking medical encyclopedia. It's all fiction. So, always be open to getting a second opinion if something isn't working.

Doctors don't diagnose. They eliminate possibilities. Sometimes. Truth is that medical science is not advanced as we'd like to think. My liver started bleeding spontaneously last year. Put me in the hospital for weeks. Nobody seems to know why this happened, what caused it, or whether it will happen again. The surgeon literally shrugged and told me, "eh, it's weird. We'll probably never figure it out. Best of luck to you!" It was very similar to that awful day as a child I realized adults don't know everything and, in fact, are just winging it on a daily basis.

There are so many wild things living in the microbiome of a human's skin. Demodex are a great example; little mites that live near human hair follicles. They look horrific and they feed off of sebum, sweat, dead skin etc.
Many things are localized too; the things living in your eyelash follicles are not the same as the ones living on your elbows. We're a whole universe, and even our skin is colonized by bizarre little f*****s
Edit; a lovely little quote I found online, about Demodex
"When you sleep, the mites come out of your skin’s pores, mate, then go back into your skin to lay eggs."
Sexy.

Justin Tyme 2 months ago (edited)
I’m a retired nurse. I saw lots of non-healing diabetic wounds. Capillaries (the smallest blood vessels - the ones that feed the body cells) are measured in micrometers AKA microns, which is one millionth of a meter. The interior diameter of capillaries averages 8 micrometers. A high glucose level causes your blood to literally become syrup, which cannot pass through capillaries. No blood flow to some cells those cells will die and become food for bacteria. All it takes is one tiny break in the skin, and the bacteria will be feasting. I had several patients who ended up losing a foot or a leg because they nicked their skin while cutting toenails.

When you die, the bacteria that used to help digest your food, now digest you….
FoxEcoLimaIndiaCharlieIndiAlfa 2 months ago
Makes sense, all these microphages/bacteria do is eat, which helps us digest the food we consume. If you die, there's no more food for them to eat up, so they move on to whatever else they can, they can't differentiate between tissues/flesh.
#19
That doctors don’t know everything and you can go years without getting a diagnosis while being in unspeakable pain. I’m going through this right now.
19 months of this. I can’t handle another few more. How can something that hurts this bad and feel like a broken rib not show up or be known after almost two years of tests? At the end of my rope here.

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.
#22
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.

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.
Ovata Acronicta 2 months ago
I had tons of ear infections as a kid. Medication wrecked my 6 year molars, have had 3/4 of them drilled. I am also uncertain if my right ear canal is messed up as a result of the infections or if it being oddly shaped made them more likely - it's very narrow and sensitive: stimulating a nerve at the base of my neck itches all the way up in my ear, and it itches horrendously in my ear if I have tonsil stones on that side.
#26
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.
Max Fox 2 months ago
Breathing faster doesn't increase the oxygen levels in the lungs by much - it's 16% oxygen on exhale, and 21% in the atmosphere. However, breathing fast can lower the CO2 levels in the lungs by a higher percent and that can mess up breathing, which is why happens with hyperventilating. So you either up the CO2 in your lungs by doing something like breathing into a paper bag, or you faint, and your breathing goes back to normal.
#27
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.
#28
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.

Your tonsils can turn against you and hurt your immune system. I had mine taken out at age 21 after an abscess nearly killed me.
Child of the Stars 2 months ago
In 2nd grade, my sister had strep throat several times, and the doctor recommended getting her tonsils removed. Until, while being seen for an entirely unrelated matter, my brother was being seen and the doctor noticed HIS tonsils were swollen and red. Turned out he was carrying the bacteria but was completely asymptomatic; a heavy dose of antibiotics for him, and voila, my sister stopped getting strep!
#34
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???

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.

I don't know where this was happening. When I was in med school we had paid "models" who would take us on a tour of their cervix. "No, it's a little to the right. That's it. You should see it now." It was weird as heck. But everyone was consenting and no one was violated.

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.
Max Fox 2 months ago
I hate these claims just thrown out there. Which POWs? By who? Where? While there were medical experiments performed on humans, it was mostly by Nazis on Civilians in concentration camps. As for trauma and emergency medicine, medical personnel were experimenting on their own wounded every day, and in every war. When doctors are getting dozens to hundreds of trauma patients every day, they are trying out all sorts of new things, because the old things don't work.
#41
In the 70’s they thought babies didn’t feel pain so they preformed surgery without anasteisa.
Laura Lawson 2 months ago
This isn't exactly true. They didn't perform surgery on an awake screaming baby. It would still be anaesthetised, but it was more for the doctors ease than the baby's. Plus they knew that babies felt pain, any parent knew that! It was that they thought the baby wouldn't remember the pain therefore it didn't matter if they used pain relief or not. It still sucks & is a hideous thought but fortunately, beliefs change.
#42
I just learned about SJS, where you get an adverse reaction to a medication by your skin falling off. It happens at seemingly random too, but some medications are more prone to cause it. Fun stuff.

If you sever your spinal cord you can get a condition called priapism (erection that doesn't go down). Treatment is draining the blood via syringe from the erect penis (or rarely, leeches).
Huddo's sister 2 months ago
Men joke about how great it would be, but those who do experience can tell you that it is nowhere near as good as it sounds. The blood won't drain and the pressure of it causes pain. I highly doubt you could actually cum while it is going on either. It can cause permanent damage too.

The spinal cord is simply a pathway for nerves, so it depends on where it gets severed. If you don't die first medical intervention can take care of everything that normally relies on messages using the pathway. If you're too young to already know about him, ask Google about Christopher Reeve

If the anesthesiologist f****d up you wouldn't know
edit:
since everyone is sharing their story i'll share mines. i was diagnosed with bladder cancer early 2022 with signs i ignored late 2021. between april 2022 - june 2023 i went through 5 surgeries to remove the tumors in my bladder. they kept coming back.
mentally preparing myself for the first trans-urethral resection, pre-op nurse just straight up told me if the anesthesiologist f****d up i wouldn't know..or wouldn't feel anything if s**t hits the fan. what a f****n pep talk huh? hahah.
christmas 2023 i was finally clear. i still go to chemo (doublet therapy?) and see a catheter :( for gemcitabine/docetaxel.

It depends on how they f**k up. If you wake up, or even become semi-conscious, during some procedures you will very definitely know. Of course if you never wake up you won't know or care.

The beginning of birth control was originally an experiment and was wildly irregulated.

The ovaries and fallopian tubes are not connected, so when an egg is released the fallopian tube sucks it up like a straw. Ladies, this also means that any seamen that makes it to the fallopian tubes have an open door into your abdominal cavity.
#50
The placenta that is found in humans and other live-birth mammals came about from a distant common ancestor being infected with a virus some 150-200 million years ago, and evolution doing its thing. If this infection didn't happen, we'd still be laying eggs.
