We live in an age where information is instant. A quick Google search can bring up millions of results in seconds. But along with solid facts, plenty of outdated or misleading ideas keep getting recycled, and far too many people accept them without a second thought.
So when a Reddit user asked doctors to share the medical myths they still hear often, plenty of responses came in. And it’s concerning, because believing the wrong thing about your health can have serious consequences.
Keep reading to see what they had to say—just remember, for real medical advice, always consult a qualified healthcare professional directly.

Biggest myth....that Kennedy knows what he is talking about and will make American healthy again.
The guy sounds like an 80 a day smoker and has a brain worm. And people believe his medical advice over the CDC. America, you lost the plot.
YOU DONT NEED ANTIBIOTICS FOR YOUR VIRAL COLD.
As my famously blunt doctor used to say, go home and take paracetamol and hot drinks but come back if your snot turns green
Also take the whole package and don't stop because you feel better if you have a bacterial infection
Literally had this discussion just today. If you're given a four-week course of antibiotics and you feel better in three, just keep going. Even if you've only got 1% of the original 100% of bacteria left, the reason that 1% is hanging on is they have more resistance to the ABs. And if you don't get rid of that 1% all their little bacteria babies will also. And now you're in trouble.
Load More Replies...Yet every time I go to see a doctor they give me antibiotics "just in case". I don't want them because of the side effects. I read this over and over and the medical establishment keeps blaming patients when they cram them into us at every opportunity.
That's not a myth. A virus will never respond to antibiotics because it's not an infection
Viral infections certainly are infections - the clue is in the word "infection". Antibiotics work against bacteria, which aren't viruses.
Load More Replies...You will if your mucous turns green. That is usually the sign of a sinus infection. And there is a specific anti-biotic that is very effective for them.
Usually, if your mucus turns green, the cause of the infection is bacterial. It means you don't have a cold (usually caused by the Rhino VIRUS), it means you have a bacterial infection and yes, in that case, antibiotics will work. Those bacterial infections may come from inhaling infected dust/spores, for example during renovations, or for example from picking your nose with dirt under your nails.

As a friend of mine once said, "Even arsenic is all natural".
I'm not a Doctor but I work in end of life care.
So many people think hospice workers are just waiting to k**l their loved ones with morphine.
I've even heard they think we get a bonus if their loved one dies more quickly. This belief is very prevalent amongst older people.
It's incredibly insulting and hurtful.
I've heard it repeated so many times that I have lost my patience with it and have to bite my tongue.
No one is recommending morphine because they want your loved one to die, it's because they can't swallow their pain pills anymore and they're suffering.
End of story.
Sometimes hospice workers can extend grace that laws do not in these situations, not from heartlessness but from compassion.
That vaccines do more harm than good.
You know what's unnatural? Eyeglasses. You know what is natural? Being chased down by predators you notice too late.
"Women have been having babies for thousands of years" as a rationale to dismiss risks.
Child birth has incredible risks, most of which are carpet swept under the joy of having kids, and leads to a lot of shock during pregnancy, birth and postpartum.
Every would-be parent should be assessing the risks before getting pregnant. Not as a deterrent, but as a way to be fully informed as various things can unfold, and how to be ready for them.
Until sometime in the twentieth century, childbirth was the #1 cause of death for women globally as far back as we have records of it.
"Natural" supplements are better and safer than proven medications. Have seen people die with treatable cancer, heart disease, liver failure- or get very sick from these untested products. And they cost a lot. Please be careful.
I like the way Dara o' Briain put it. "And then we tested it all, and the stuff that worked became.... MEDICINE."
Not a doctor; that the cervix doesn't have nerves and thus can't feel any pain. I think the overwhelming amount of women who say getting an IUD inserted hurts enough that many have passed out beg to differ.
“The doctor told me I had 6 months to live.” Not that I can blame people for possibly misunderstanding the details of a cancer diagnosis. What the doctor actually is saying is that the median survival is 6 months. Half live more than 6 months and half live less.
This might seem trivial to some of you, but I think this misunderstanding hurts trust in doctors at the exact time they need it most. How many times have you heard something like “The doctor gave me one year to live and I’m still alive 3 years later.” The implication for some being that doctors don’t know what they are talking about.
I have seen too many people forgo effective treatment to do something crazy like smoke marijuana instead of having a bone marrow transplant for their leukemia. And misunderstandings like this are partly to blame.
Doctors could explain it a bit better, like this, then. Also sending home written information instead of piling on options, advice and info in the doctor's room, upon diagnosis that brings on shock to the patient.
"Vaccines cause autism.".
ICU nurse here. This is a new one I just heard today. A patient’s family member asked me if the blood we were giving the patient had been screened to make sure it wasn’t high pressure blood. I didn’t delve into what they meant by that .
You can catch a cold by being outside in the cold and wet without a jacket on. Or catch a cold just by sitting around in wet clothes.
File this under yes, but. The old year 2000 advice was that you can’t, however more modern understanding is that is complex. While you need exposure to a virus, factors make being cold a culprit Weakened Nasal Immunity: Research shows that cold temperatures can impair the immune response in your nasal passages, making it harder for your body to fight off viruses. Viral Behavior: Some viruses, like rhinovirus (a common cause of colds), may survive and replicate more easily in cold weather.
You need to drink 8 cups/2 liters/whatever of water a day to be healthy. There is no such evidence-based recommendation. The best science says to drink to your thirst.
**Myth 1**: going to bed with your hair wet will make you sick.
It doesn’t. It can lead to hair damage and headaches, but it doesn’t make you sick.
**Myth 2**: you don’t need to take your whole antibiotic regimen, you can stop when your symptoms stop.
For the love of god, please don’t do this. Please always finish your entire antibiotic regimen as directed, unless your doctor tells you otherwise.
I have never heard of it causing damage or headaches, does anyone have more info on how? I go to bed with wet hair all the time, as it means it curls much better.
The ivermectin is better for cancer than standard therapies myth is growing. And whenever a patient shows data it’s always cell culture data.
PEE. IS. NOT. STERILE.
Less a myth. More a lack of education. Hydrogen peroxide is decent for using at initial wound cleansing. Repeated use actually resets the healing process. Most don’t know this.
Teeth are luxury bones and that's why insurance doesn't cover them. Teeth are not just cosmetic they are also needed. Without teeth the ability to chew food properly diminishes, leading to potential nutritional deficiencies and digestive problems. Not having teeth also causes bone loss in the jaw and speech problems. Not to mention all the trouble that comes with an infected tooth. They can and will k**l you without treatment.
The idea that teeth are luxury bones is so weird. After breathing, eating is the most important body function, pretty essential to staying alive. (Yes, I know you can be fed through tubes in the hospital and that you could survive on blended food, but in nature it's super essential, if an ancestor was unable to eat, it would die)
That MSG is in some form toxic- nope. That was powered by racism and xenophobia. There’s been no study to show MSG causing any of the side effects previously attributed to it.
A person can be sensitive to MSG, but that's not the same as it being bad for you.
That I get rich from vaccines.
Vaccines don’t reimburse s**t. Kids don’t reimburse for s**t. I drive a used Honda and save thousands of more lives than the neurosurgeon in the Maserati. I’m fine with that. Just stop saying I’m rich because vaccines. No. I’m doing okay. But many many more kids are alive who wouldn’t be.
Wearing reading glasses with make your near vision worse. No, aging makes your near vision worse.
“My eyes can’t be dry, they’re watering all the time.” Watering is in fact a symptom of dry eye disease.
Eating carrots makes your eyesight better. Nope. Carrots contain vitamin A which is important for vision, and vitamin A deficiency can definitely result in vision problems. But more carrots does not equal better vision.
Ha ha! The carrots were an absolute gem of an urban myth. It was invented to hide the fact that we had radar units in our planes in WW2, so the enemy wouldn't guess the reason our pilots could see them in the dark.
The number of doctors that have extreme bias is super scary. Won't listen to someone based on racism, sexism, or classism... common. Causes a lot of issues, you have a group of people who are convinced from a very young age that they are too smart to have bias, and simultaneously told they are smarter than anyone else, rolling their eyes at all manner of sickness, like MANY believe people are faking, if they dont have a quick diagnostic tool to confirm, and the patient is not the type of person the doctor considers competent enough to describe or even experience illness. I have a friend who is teaching doc at a major hospital, and he is like the most challenging part is getting some of the bias and arrogance out of young doctors, many of whom have no frame of reference for other cultures and are astounded to learn many patients have had damaging experiences with doctors, based on mythology and bias doctors are engrained with.
But but but if you have the vaxx, you'll break out in cows! It's true! I saw the photo! https://www.bbc.co.uk/news/uk-england-leicestershire-50713991
Not in the U.S. but I've done some conferences there and have heard some colleagues claim that different races/s*x naturally have different pain tolerance levels.
While it's true that people have different pain tolerance levels, I've seen no evidence suggesting there's any correlation to race or s*x.
That you have to take the bullet out.
You don’t.
The holes the bullet made are the problem. Just taking the bullet out doesn’t fix anything. Hard eye roll every time I see this in movies.
Yeah, but getting it out is still necessary, just not immediately.
Vaccine-skepticism. They are one of the simplest, most-effective interventions we have ever created.
“They just want to take their organs!” I can promise you the doctors and nurses taking care of you get zero dollars in bonus for anyone donating organs.
This assumes that money is the only motivation. How about "the kid who will die without a heart transplant" compassion?
Not a doctor, but the person who believed a myth from TV: that autopsies are commonly performed. The doctor told me that in the state only about 2% of deaths are autopsied.
Glasses make your eyes weak or lazy. Glasses solve a optics problem.
Aldous Huxley was a big proponent of the Bates Eye Method. That method was a series of eye exercises that claimed to reshape the eye and improve vision. At one point he was giving a speech and apparently reading his speech without his glasses. The audience was astounded! Then he started to falter. Huxley had memorized his speech. He forgot it and could not really see what he wrote. Eye exercises are effective for eyestrain but cannot reshape the eye.
“You’re too young to be experiencing menopausal or hormonal symptoms.”
Perimenopause starts as early as 35 for some, some women go through ovarian failure before 40. HRT is incredibly important and helpful. Hormonal issues are a big concern for cardiovascular, osteoporosis, metabolic risks, shorter life expectancy and weight issues. Autoimmune disorders should also be considered alongside diagnosis.
HRT does not cause any higher likelihood of blood clots or cancers than Birth Control does. Rx the HRT as it bypasses the liver and has fewer potential side effects. Do not let your patients suffer please. Refer out to a specialist if you’re not well versed in endocrine concerns. Birth Control is not safer than HRT and HRT is absolutely necessary with POF until at least age 55.
Can confirm. Not that I blame my doctor, I was 36 and we were both assuming it was something more sinister, and that's better than the other way round.
Dragonflies sting.
They don’t.
I’m a doctor of Entomology.
My grandmother told us when we were little that if we said "bad words", a dragonfly would sew our mouth shut. I call my sister a p**s head once and was afraid of dragonflies for a while after that.
Not a Doctor, but still AMAZED at how deeply people hold the outdated idea that taking huge doses of Vitamin C when sick or “feeling like you are coming down with something” will have a major effect or otherwise prevent the full severity of the cold or whatever. Vitamin C is of course necessary for good functioning of the immune system, but no, it isn’t some kind of miracle cure or supercharges your immune system.
Catching a viral illness because it's cold outside.
Sugar feeds cancer
"Nipping" a bronchitis in the bud by taking antibiotics.
Bacterial bronchitis WILL be nipped in the bud by antibiotics. It won't if it's viral.
Pediatrician here. I’ve gotten the “vaccines cause autism” myth twice in the past month alone. It’s frustrating and a bit sad.
I have to wonder why all these people think this because, by their reasoning, they, and everyone they know, would be autistic.
Insurance covers it.
Whenever someone has a concussion and we send them home after a normal CT scan, I always get asked how often they need woken up and checked on.
Vitamin C cures/prevents a cold.
Lies! I’ve been taking vitamin C for weeks yet I still managed to develop 2 infections within 1 day of the other getting better and had a 2 day long fever. If anyone dare bring up this myth again I’ll shove it up your a*s
You can be sure that if there is ANY value in a compound, some pharma megacorp will have it locked under patent. So when someone claims you can just take some random supplements or mix up some cure all concoction they are pushing snake oil.
Wet hair will give you a cold if you leave the house.
I am a patient. I have idiopathic intracranial hypertension, also known as IIH, or pseudotumor cerebri.
It's basically too much cerebral spinal fluid in your skull, crushing your brain.
Often, it also crushes your optic nerves - causing blindness. It's called pappillademia.
So, doctors use pappillademia to measure the severity of IIH.
Here's the thing. IIH without pappillademia exists. It doesn't necessarily cause eye issues for everyone.
There are a surprising amount of doctors around who insist "your eyes are fine so your brain is fine."
I went thru five specialists till I found one that believed me. The normal pressure is 5-15. Mine was 40. They ignored that I had other classic symptoms because my eyes were okay.
I run the IIH discord and it's an issue that pops up CONSTANTLY.
The fact that ophthalmologists, neuro-opthomologists, and neurologists can't get it thru their heads that pappillademia is a sign that IIH exists, that pappillademia healing is a sign it's getting better - but if it doesn't exist doesn't mean the patient doesn't have IIH. They're actively hurting patients.
They need to go back to school for this illness. They're massively under trained.
That is what happens when you allow people becoming doctors with a degree from hersh and macdonald island med school
That being admitted into hospice means you’re signing your own death certificate. No, you will receive treatment and care up until the point that your body can no longer take it.
People “graduate” from hospice all the time because they no longer need it and the people who really do need it often don’t want to be in it.
My dad left a hospice and had a further 6 months before going back finally. An actual 'success' story, even at 85.
Nurse practitioner but: having a high BMI alone automatically makes you unhealthy. Losing weight is hard, but eating a balanced diet and exercising can definitely help lower your risk for high cholesterol, diabetes, etc. even if the scale doesn't budge. Don't give up!
BMI is a bad messurement unit because it's purely based on weight and not on the difference between muscle and fat for example
Former speech therapist here, who dealt with adults with difficulty swallowing. So many people think that if you are choking, you should raise your hands above your head to dislodge the food.
That babies/toddlers dont have kneecaps….they have kneecaps they are just cartilage so you cant see them on xray. Take a peek at a xray of a toddler/baby foot or hand and it would look like they have no bones at all.
They have a bunch of smaller bones and cartilage that will later fuse to form kneecaps but technically don't have fully formed kneecaps.
“Stroke level” blood pressure. As if there’s a certain blood pressure at which point you will absolutely have a stroke. High blood pressure is a chronic problem. Stroke is a consequence of long term high blood pressure, not a one off day of high blood pressure.
ETA: high blood pressure in pregnancy is more a concern for seizure and not stroke. That said, please follow your OB/Gyn’s guidelines regarding blood pressure in pregnancy.
However, some ethnic minorities can have egregiously high BP from a young age - teens/20's - and are very much at risk of life ending episodes. In Asian countries, the prevalence of hypertension in the pediatric age group has become more prevalent than ever before with the increasing obesity epidemic. *https://link.springer.com/article/10.1007/s11906-014-0495-z*
“You are only prescribing me a medicine because you get paid for each prescription you write.” False.
Not a doctor but I was told that giving birth on my back was the best most natural position. This is very much not true.
Squatting is the best way. When you're on your back you're just fighting against gravity and having to push harder. The doctors just want easy access to your v****a and see everything.
Electroconvulsive therapy is t*****e and will destroy your brain. When in reality it's the most effective treatment we have for certain mental health disorders like depression and catatonia.
ECTs can cause memory loss and may affect your ability to concentrate. Your doctor should discuss the pros and cons of the therapy with you to determine if you will benefit from it.
Am GI doctor focusing on IBD pts (I myself have Crohn's). I see/hear a lot of bad advice or outdated myths. "Just eat less processed foods," "IBD inflammation is mostly dietary related," etc. It's increased in recent years, due to the focus on "gut health" in alt-right crunchy rhetoric. A persistently nefarious one is exaggerated claims about how dangerous biologics really are. There are risks, but risk assessment is a basic part of treatment management.
A pretty harmless myth that persists is "nuts,seeds,popcorn cause diverticulitis." It used to be standard advice, but there's actually no significant evidence that they inflame diverticula more than other foods. I don't care if someone wants to avoid them, though, bc it isn't actually *harmful* like some of the above myths.
My grandad was firmly in the "nuts, seeds, popcorn cause diverticulitis" camp. He wouldn't even eat tomato seeds. He did have diverticulitis and I'm sure was told to avoid seeds by his doctor, but he was very obsessive about it. He was also very worried about getting bowel cancer, because of family history, so had annual colonoscopies, well before the age most people are advised to. This isn't a problem, and could have potentially saved his life, but it felt like his whole life revolved around this. Ironically, my grandma had multiple health things that were overlooked/unbelieved by him, because he thought she was just being ridiculous. Like she 'couldn't possibly' have hayfever, because it didn't present like his, and developed later in life, so she suffered with a constant 'drippy nose' (her words) that she never saw a doctor about.
Not a doctor, but extremely frustrated that my parents seem to think that the medical industry is not designed to cure you, but keep you sick and dependent on them forever so they make boatloads of money off of you.
Also they seem to think that all medicines or vaccines or whatever just gives you whatever it’s supposed to be helping.
Needless to say my Dad didn’t like me saying that maybe the insulin he takes is what’s giving him diabetes after he told me that Covid tests give you Covid.
I’ve personally witnessed my three children born. I can without a doubt verify that s**t ain’t no walk in the park.
That black people are more tolerant of pain than white people.
That we can, or would want to, sort by COVID vaccinated and non-vaccinated blood. Usually comes up every few months, and used to be almost weekly. .
Not a doctor but when I worked in Emergency, I saw a man poisoned by WD40. He sprayed it on his arthritic knees.
PS....it doesn't work AND don't do it!! He was lucky though, we caught it before his kidneys died.
I have had multiple patients concerned about operating on their non-metastatic cancer because they are certain that if air touches the tumor it will metastasize.
But...some tumours are 'encased' Surgery might damage that casing, and allow metastases to start nearby. It's not the 'air' but disruption of the casing, so a misunderstanding of the 'truth'.* Physical Barrier: A dense fibrous network or membrane can encase a tumor, acting as a physical barrier that holds the cancer cells within a specific area. A "Casing" or Capsule: This casing, sometimes a result of a process called desmoplasia where the surrounding tissue forms a dense network of fibers, can provide a boundary that must be overcome for metastasis to occur. Key to Limiting Spread: The presence of such an intact membrane is thought to be key in preventing metastasis. *
If you can move it (referring to any body part), it's not broken.
MY cousin slipped on the ice. Her hip hurt but she could get up and walk into her apartment. No one saw her for a number of days. They went into her apartment and found her on the floor dehydrated and conscious but unable to move because her pelvis had broken.
Doctors make money from prescriptions or vaccines. Simply false.
Doctors don’t make as much money as insurance companies, hospitals, or corporations that own medical practices do.
Not a doctor but a med student
Carrots are good for the eyes. Propaganda so good that people still believe it 80+ years later.
See comment above. Urban myth created to hide our radar units on planes and con the enemy into thinking our pilots could see their planes at night because of carrots. Very, very effective. Obviously!
Not a doctor but a physiotherapist - if you have a hip/knee replacement you shouldn't get out of bed and barely move for a week at least. I mean you can, but enjoy having reduced mobility in that joint going forward.
Veterinary edition: that the temperature of a dog’s nose is an excellent indicator of their health.
That you can’t combine acetaminophen and ibuprofen. Also the long standing nursing myth that you can’t give febrile patients a blanket. That s**t is just cruel.
Study a few years ago was that 1 x 500mg paracetamol plus 1 x 200mg ibuprofen was 10% more effective for pain and fever than taking 2 of either. *https://www.journalslibrary.nihr.ac.uk/hta/HTA13270*
Doctors get kickbacks from pharmaceutical companies. Not since the 90’s, grandpa!
Not since the 90's? Just one instance: "...The study found that, in 2014 and 2015, οpіοіd manufacturers paid hundreds of doctors sums in the six figures, while thousands more were paid over $25,000..." - https://hsph.harvard.edu/news/opioids-doctors-prescriptions-payments/
Not a doctor but I can’t let this go. Health teacher and later college anatomy teacher drove into us hard that using condoms will not safeguard you from all STD’s and you still need to be tested. I still see everywhere and get argued with that you just have to wrap it and you can’t get anything.
They are not 100% effective and you may not be able to see every micro tear in the c****m. They will definitely not protect you from crabs or drippage into other orifices. Using 2 condoms is not better than one. It actually compromises the material.
1. The flu shot DOES NOT cause the flu.
2. “low grade fever”
3. “I have a high pain tolerance” (“pain tolerance” is insanely multi factorial… but this usually means they have a lower-than-average pain tolerance)
4. The need for antibiotics for bronchitis.
5. Body/Brain getting “tolerance” or “used to” an antidepressants after a few years. Look we don’t even know why these pills work in the first place, okay? But the serotonin levels in the brain rise hours after taking an SSRI… but they take weeks to take effect. .
After years of being p*o-hoed regarding my pulse - usually between 48 and 55 - my doctor has asked me to check it several times. I've been told in the past that it's good at that rate - it's what athletes have. I'm disabled and obese with high blood pressure and have been for a long time.
Vitamin K levels increase to normal levels at day 8 of life. Nope, baby is still at risk for spontaneous bleeding without intramuscular vitamin K.
Plus which the highest risk of brain haemorrhage (the main neonatal complication of Vitamin K deficiency) is in the first 48 hours. "But, but, but injection in my little baby...!" But brain haemorrhage in your little baby.
"Stroke-level blood pressure".
There is no such thing. I've seen people survive in the 210s for years without a stroke or heart attack. Were they lucky? Sure. Should you let yours stay that high for that long? No.
It is important for you to have regular BP checks as part of normal preventative screenings/physical exams. If you have high BP, it is important that you take your meds and have it monitored more closely. Do not go to the ER for high blood pressure. If you are having stroke or heart attack symptoms, go to the ER now, no need to check your BP first.
Doctors are still pushing low fat as diet advice, even though it’s been proven wrong.
RN, not a doctor. But we see a lot of “dry drowning” as chief complaint un the summers IN the ER.
Lateral hip pain is bursitis. It's been known for 2 and a half decades that it is not.
So what is it. I have this in both hips and have been told it's bursitis.
Okay, but I hope doctors have some humility about this. Lots of medical "myths" are things that were once believed by doctors and were pushed at us as the absolute truth by doctors, science journalists, and the government. And some of the things that are "known" now and proclaimed with absolute certainty will end up being disproven in years to come.
Doctors didn't contribute ANYTHING to this list - it is just a bunch of random people posting stupid cr@p. This was a terrible post
Right now it's everything "gut". Gut health, gut microbiome, repair your gut, leaky gut. There's a lot of exciting research going on, but no standard of practice showing that treating your gut will treat or cure almost any disease outside of occasional GI issues. It won't help your psoriasis. It won't cure your lupus or MS. It won't fix your heart problems or cancer. It's the new cleanse/candida/chronic fatigue. And watch out for cortisol - that's coming around the bend and will soon be the cause of all diseases and problems.
