Doctors Are Sharing The One Thing They Wish Everyone Knew About Their Body, And People Are Shocked At How Uneducated They Are About Themselves

Yahoo20-07-2025
It's pretty commonly known that education about the human body isn't as in-depth as it should be in traditional schooling. So Reddit user u/assassinmice was compelled to create this thread asking doctors what they wish everyone knew about their body. Here are some of the top-voted answers:
1."Ejaculating blood happens to most people at least once in their lives. In 99% of cases, it resolves within a week without taking any action. Peeing blood (for both sexes) is a serious medical emergency, and you should immediately go to the ER. People think it's the other way around."
—u/StardustDoc
"In males, there is a vestigial remnant of the uterus located in the prostate. It's called the prostatic utricle. It is a duct that leads nowhere. It sometimes has some remote endometrium in it and can produce one drop of blood every 28 days."
—u/Sillyakua
2."Administering CPR compressions ASAP is one of the greatest indicators of successful outcomes."
—u/hodl_this
"In an emergency situation where you are giving first aid/CPR to someone, instead of stating general instructions to the group of inevitable onlookers like 'someone call 911' and 'someone get a defibrillator,' point to someone and say, 'You call 911' and 'You find a defibrillator.'
This prevents the bystander syndrome, where people think someone else will do it. It gives clear instructions, allowing for a more efficient process where literally seconds could mean life or death."
—u/Cm0002

3."Your kidneys and liver cheerfully do all the toxin elimination you'll ever need. Cleanses and other 'detoxifying' products are bullshit and a waste of money."
—u/taRxheel
"Unless you have liver or kidney failure, your body detoxes itself really well. Don't get scammed by these detox teas and whatever!"
—Anonymous
4."So many people don't know where the orifice each gender urinates through really is. Urine exits the body of people with vaginas through the urethra, a small tube located in the vulva, between the clitoris and the vaginal opening. In people with penises, the urethra passes through the prostate gland and the penis, and opens at the tip of the penis.
—u/SuspiciousLemur
5."Please do not use soap or douching products inside your vagina. It has a delicate pH balance, and this is how you get yeast infections. Wash your labia, but do not clean internally. The vagina is self-cleaning just like your eyeballs. Do you wash your eyeballs? No. Do you wash your face? Yes."
—u/H0use0fpwncakes
6."You often will feel normal with high blood pressure. It's often found incidentally. So, don't wait until it gives you symptoms you don't want to go through. To figure out if you're asymptomatic, get checked at least once a year if you're over 35 years old."
—u/doctor_d9
"High blood pressure doesn't have symptoms a majority of the time. It's called the silent killer and causes a plethora of other illnesses."
—u/halfbaked05
7."Mental health IS AS IMPORTANT AS PHYSICAL HEALTH. A mental illness can kill you, just like a physical illness. And no, you can't 'snap out of it.' News flash, parents: This includes gender dysphoria. For fuck's sake, if your kids are trans, let them be themselves."
—u/uniqueUsername_1024
8."The immune system is an incredibly complex and nuanced organization of cells that communicates readily to destroy anything deemed hostile within the body. It helps explain why vaccines are supposed to work, why allergies come and go, and why transfusions/transplants are hard to successfully pull off."
"Here is a brief explanation of how allergies work, using pollen (allergic rhinitis) as an example:
Your immune system senses pollen in the body. It doesn't appear to be one of your cells, so the B-cell collects samples of it, relays it to a Helper T-cell, which in turn helps specialize the B-cell to become one of two cells: effector and memory cells. Effectors mass produce antibodies, while memory cells are reserved for future invasions (this is why initial exposure to a new substance may not necessarily trigger allergic responses. The signal is still weak as the immune system is still acclimating to a foreign particle). Antibodies flood the pollen particles and signal for basophils/mast cells to release histamine, the hormone responsible for inflammatory responses. This is where the runny noses and sneezing come into play (and for more severe allergies, anaphylatic shock).
Allergies may fade out over time for several reasons. When exposed to a non-threatening level of an allergy for a long enough time, the body decides that it's not really a threat anymore. Furthermore, as people age, the immune system weakens, making it harder to detect and overreact to allergies."
—u/Dasians

9."I'm a dentist. If you don't take care of your gums, your teeth will fall out of your head, and you'll get pissed at me when your jawbone atrophies and your denture doesn't fit anymore. Essentially, periodontitis causes inflammation and recession of the gums, which in turn causes inflammation and recession of the bone. After that, teeth start getting mobile and falling out."
—u/TofuDeliveryBoy
10."How to self-check for skin cancer: If you see any moles that are asymmetrical, have a border (odd, like they're jagged), are different colors, grow in diameter, or evolve, go get them checked out. It might be skin cancer."
—u/evgueni72
Here is a full self-check exam recommended by The American Cancer Society.
11."GET SLEEP! Psychosis can happen if someone hasn't slept or hasn't had good sleep for extended periods of time. AND DON'T JUST RANDOMLY STOP YOUR MEDICATION BECAUSE YOU FEEL BETTER. You feel better because you have a consistent amount of whatever is leveled in your body now. And now that your body is hitting equilibrium, everything is going great, so KEEP DOING WHAT YOU'RE DOING. I've seen people go on and off their medications for years, and it really starts to mess up your body if you do that for too long."
12."The frequency of bowel movements can range from every three days to three times per day and be considered normal. Having three soft stools per day does not mean you have chronic diarrhea."
—u/HarbingerKing
Related:
13."Type 2 diabetes is more serious than most people realize. I work as a doctor in hemodialysis, and most of them are due to diabetic nephropathy. It also affects your eyes, nerves, immune system, etc. Simple life changes can help you."
—u/kingofneverland
14."The colon is, in general, air-tight. Therefore, your dildo ALWAYS needs a flared base. Once it gets up past the point that I can grab it out, it's vacuum sealed in."
—u/dryyyyyycracker
15."I'm a vet. Amputated limbs do not grow back. I've had far too many people asking how long it will take for their pet's amputated limb to grow back, so I'm assuming a few doctors out there will have had patients asking the same of their own missing limbs."
—u/rubypiplily
Salamanders, lizards, and certain fish (like Starfish) are the only living creatures that can regenerate their limbs.
16."Earwax is normal. You shouldn't try to remove it. People cause all sorts of problems with Q-tips and (god forbid) ear candles. They don't work and can cause you harm. If you genuinely need wax removed, go to a professional."
—u/rhino_surgeon
17."Many simpler diseases in the body can be compared to a car. When you don't get regular checkups and take regular care, it's not like you'll notice something bad happening right away. Just like how you won't notice a missed oil change a couple of thousand miles later. But diseases like diabetes, high blood pressure, alcohol dependence, etc., sneak up on you. Just like how eventually, that engine won't run as smoothly."
—u/z3roTO60
18."Period blood doesn't come from the egg itself, but from the shedding of the uterus lining. I have talked to way too many people who believe that the blood comes from the egg itself, and I just think it goes to show how much the sex ed program needs to be modified."
—u/octopoduss
Related:
19."Injuries accumulate. I cannot stress this enough. Little kids have no business lifting heavy weights or getting pushed so hard in sports by some of these 'coaches' who seem to have little knowledge of physiology or don't care about the long-term impact of the regimens. Stuff like this really changes people's lives."
—u/VladJongUn
20."You can't EVER get teeth enamel back."
—u/shittyTaco
21."That there is a wide range of 'normal'. Don't be embarrassed by your body. Having said that, if you are concerned about anything, ask your doctor. We have generally heard it all before, and trust me, we have (nearly always) seen it all before. Maybe you have something that has been bothering you for ages, but you were too scared or embarrassed to ask about it...Just ask! It might be 'nothing' and you have been stressing about it for no reason. If not, then you are at least one step closer to getting it fixed. No one can help if they don't know. There are no dumb questions. YOU know your body best. So speak up! Don't wait for the doctor to 'ask the right question.'"
—u/frangipani_c
22."Smoking is one of the absolute worst things you can do for your body. It is a risk factor for almost every preventable disease, including heart disease and heart attacks, strokes, almost every type of cancer, diabetes, COPD, kidney disease, macular degeneration (blindness), and so much more. I know quitting smoking is hard, but please give it a try, for your body's sake!"
—u/ocean_wavez
23."Your body needs water. DRINK IT."
—Anonymous
You can read about how much water you need per day here.
24.And lastly: "You only have ONE body and your behavior now (drinking, smoking, not taking medicines, etc.) will impact your life quality and expectancy. It sounds logical, but very few patients really realize it."
—u/Clamoxyl

17 Divisive Foods People Absolutely Hate And Refuse To Eat — And Honestly, It's Sooo Controversial

Even if a food tastes good, sometimes the texture is just an obstacle one cannot overcome — and that's okay. Recently, Redditor u/applefrickinsauce asked those in the Reddit community to share the foods they refuse to eat because of the texture, and, you know what? Fair. Here are the foods people 100% won't eat: 1."Cottage cheese. The curds are gross." —myweedylawnsucks "Something about it being lumpy really sets my brain off. Like, 'Milk stuff isn't supposed to be lumpy! Don't eat it!'" —Hailstorm303 2."Mushy peas. I was forced to eat them at my primary school. Even now, the smell of them makes me gag." —Top-View7248 3."Snails. Slimy bastards, they are." —Jazzlike-Basil1355 4."Fatty meat and cartilage. The texture makes me gag big time." —ShinyVanillite 5."Ketchup. I hate the way it smells and the way it separates when you wash it off of plates." —Ok_Wallaby_8001 6."Raw tomatoes! I love tomato sauce, tomato paste, tomato soup, and anything else made from tomatoes. But I won't eat raw tomatoes on my sandwiches or in salads." —GoodFriday10 7."Oysters." —Jura1575 8."Eggplant. It's so spongy and fibrous." —NoseInternational794 9."Figs. The inside is too insect-y for me." —fujoshikimchi 10."Liver and onions. Whenever my parents made it for dinner, I'd go to my friend's house." —Massive_Garage7454 11."Chicken wings and ribs. The bones and everything..." —AAEgurl26 12."I cannot stand mushrooms. They smell so awful, and the texture is just disgusting." —Financial-Job4779 13."Tripe. It's like eating bits of slimy towel." —Difficult_Carob7063 14."Lima beans have this weird, chalky, powdery texture that makes me skin crawl. Even thinking about biting into one makes me shudder. As a kid, my mom would try sneaking them into soups and casseroles, but I'd always spot them and pick them out. The texture is like eating wet sand, and I just can't deal with it." —PerfectCutie_ 15."Durian." —davidicon168 "I recently tried durian for the first time. Really couldn't get past the smell. The flavor and texture were not helpful, either. Zero stars." —12Wanderful 16."Pears. They're always gritty and sandy." —spidergirl79 "Eggs. They disgust me, and they've disgusted me since I was a kid. I'm in my 30s now, and I haven't eaten eggs for as long as I can remember. People find it weird, but eggs smell like farts, and they're slimy and gelatinous. I find them completely repulsive. I don't care about eating stuff where eggs are used as an ingredient like pasta or baked goods, but eating eggs alone is, in my mind, roughly equivalent to eating a turd. My fiancée used to love them, but she's vegan now, and our household is one of the very few that hasn't been worried about egg prices this year (which is nice, at least)." —WrestleSocietyXShill For me, the food that I can't eat due to the texture is OATMEAL! I hate how goopy and bland it is, and not even adding toppings helps. What's a food you refuse to eat because of the texture or smell?

18 Things That Are Actually Really Healthy, Despite Many People Thinking They're Not

I don't know about you, but it feels like there's a new health fad every week. First, there was intermittent fasting, then there was keto, and now, people are arguing about seed oils. I'm struggling to keep up. With so many narratives about certain things being "bad" for you, I'm starting to forget that some of that just isn't true. Luckily, I stumbled upon one Reddit thread (which you can see here), where people listed the "unhealthy" things that are actually really good for you, and it's a refreshing reminder. Related: Here are 18 things that are perfectly healthy and fine to do, despite some people thinking otherwise: Everything in moderation is key. 1."Doing nothing. Having a moment of silence." –Turtleballoon123 2."Put the baby on the floor. Babies don't always need to be in a bouncer, swing, jumper, walker, rocker, chair, etc. They do great on the floor in a safe space." –SleepXParalysis 3."It is really healthy to process some emotions and thoughts on your own. The people who have the most peace and clarity are people who can sort, experience, sit in, and evaluate their feelings without having to put it out to other people for other people to tell them what to think, feel, and do." –OptmstcExstntlst 4."Frozen vegetables. It's seen as cheap and not as good as fresh, when in fact, it's almost always healthier than 'fresh' vegetables." –Hufe Related: 5."You do not have to show up to every argument you are invited to." –Bravely_Default 6."Sleeping all day when you're exhausted. As my trainer says: If you're actually falling asleep, you clearly needed it." –EndlesslyUnfinished 7."Potatoes. It's the oil and what we do to them that makes them high in calories and unhealthy." –yamammiwammi 8."Popcorn. Without all the artificial butter flavorings and low-quality oils, of course. Popcorn is a whole grain, and super high in fiber. As far as snacks go, it's about as good as it gets." –Its_Waffle Related: 9."Being around dirt. Especially for kids. Exposure to a natural, somewhat dirty environment helps your immune system develop properly, which in turn helps reduce the chance of developing allergies or immune system diseases, and even reduces some mental health issues." –the_original_retro 10."Salt. It's been demonized by the 'health' industry for years, but it is WILDLY necessary for damn near everything in your body." –Secret-Spinach-5080 11."Having fat in your body, not an excessive amount, though. You don't need to be ripped with a completely flat stomach to be healthy." –PlasticScheme3609 12."Chocolate.... the right kind. Dark chocolate with 80% or more cocoa has massive amounts of extremely healthy stuff in it. It makes your body release stem cells in the blood, which repair almost everything." –BubiMannKuschelForce 13."Being angry. It's as valid an emotion as any, and sometimes you just need to be angry and let it out. Reacting in anger is never a good thing, though." –TheYankunian Related: 14."Saying no to children and letting them feel sadness sometimes so they can appreciate joy eventually." "My mother-in-law's grandchildren are so spoiled that nothing can make them happy; they are completely self-absorbed and never say a thank you, and they can get absolutely anything they want anytime. I've never seen children like that, and I believe that while she has good intentions, this might be harmful later." –cesonis 15."Giving your body a chance to fight off minor illnesses before turning immediately to antibiotics/virals. Like no, don't let that dog bite fester your arm right off your shoulder, but if you can walk through the sinus infection with a bottle of NyQuil, do that." –alphaturducken 16."Playing video games in moderation." –AromaticHydrocarbons 17."Not showering every day (you can wash sensitive spots every day, though, if you want to, that's understandable)." –Seirazula 18."Fruit. There are people out there who think fruit has too much sugar 🙄 " "I had a woman who full-on believed this sentence. She said, 'I'm being bad and getting a banana, it's my sugary treat.' BE SO REAL RN OMFG. Sugar isn't the enemy people!!! Moderation and sugar that our body can process easily is the key. Honey, maple syrup, sugar in fruit, and less processed/not bleached sugar are fine! Pure cane sugar is yummy, your generic sugar has so much stuff in it, the less processed (processed isn't bad since we need some of it), the better!" –MrCabrera0695 What else belongs on this list?
