How Much Poop Is Stored in Your Colon?? 

"Your colon is much cooler than that" That's the nicest thing anybody has said to me in days.

Respect to person who donate their body to science

This guy...knows his shit. No pun intended, I have watched him explain numerous things about the body. He always has the proper medical terminology for the other professionals, but then he also says it in a way that I don't need a 7 year degree to understand him. It makes it enjoyable to learn new stuff. Thanks, I appreciate that.

I've suffered with constipation all my adult life, it began during pregnancy with my first baby. It was chronic and got worse with each of the 4 children. I struggled to lose weight no matter what diet or exercise program. At age 40 I finally went and had colonic irrigation with a Chinese practitioner.....this was after I had been diagnosed with gall stones which I passed in agonizing pain. I was over weight and felt like garbage. The first day I was on the machine for 2 and a half hours and the amount of old feces that came out was huge. I felt much lighter after amd my swollen belly went down somewhat. I went back the second day and had the procedure again but there wasn't much left and I was completely empty in 10 minutes. The relief was tremendous and I felt much lighter. I stuck to a healthier diet after that but still suffered constipation until I went on a low carb diet and lost a huge amount of weight. The constipation got much better as there wasn't much bulk made up of bread and carbs. Just low fat protein and lots of salads and green veges. It's the only diet that has ever worked for me.

My Mom had colon cancer at 90, after surgery, she lived healthily until she passed away at 105.

As a stage 3 colo-rectal cancer survivor. I learned more about my digestive system in this 17 minute video than in the hours of appointments with oncologist, surgeons, radiologist, gastrologists, and nutritional experts. Like many of the comments have already highlighted, the presentation was incredibly informative, yet concise, making it easy to comprehend the process. At the end of the day, my medical team has helped me survive, but I wish I could have been this informed at the beginning of my nightmare.

As a medical person myself, this is very informative. I would also love to see a video explaining fecal transplants and when they are used.

Absolutely love your videos. I was raised in a medical family, and graduated from Mortuary School in 1977. Wish our anatomy class was like this presentation.

Thank you to whoever requested this topic and fact check of that irritating ad about toxic poop. Love the scientific, medical, relatable, visual approach with clinical vocabulary followed by the colloquial. Excellent use of RU-vid time. Always makes me marvel at the work our bodies do and is a lovely antidote to dysmorphia.

Im sooo happy to be living in the "Age of knowledge." Ive learned more in the last 10 years of youtube(University) then in the previous 50 years of my life. Thanks RU-vid and HUMAN ANATOMY.

I have sat through several college level A&P courses, and have practiced as a nurse for 10 years. This was by FAR the best explanation of the digestive system I have ever experienced. Thank you SO much! I will be showing it to my children and my patients.

I always figured the claims about being full of poop were bs, without understanding why. Your explanation has gone a long way in helping me understand. Thank you for taking the time to make this video.

Dude is out here literally rearranging people's guts

Dude, you are a natural born educator. Your handle on the topics and your intelligent use of descriptions is a cut above.

I love how he teaches this, so natural and easy to remember. Keep up the amazing work! Yes, very grateful to the body donors as well. Without them this information would not be available to us.

I love medicine. I never had the chance to give to the University. I studied to be a CNA in Spain, where I'm from, and I keep investigating to learn more. You guys are fantastic! I had a dangerous event 4 months ago after having my sigmoid colon removed. The part where the surgery took place literally exploded due to too scarred tissue and I spent a month in an induced coma with septicimia, plus another 2 months after waking up to a colostomy, having rehab to walk again....a whole ordeal. But I'm alive and still learning. Thank you for your incredible job here! I'll keep following your videos. ❤

If this guy taught A and P at my schools, I would listen and learn!! He is enthusiastic about this subject!!!

I have taken Anatomy, physiology, and microbiology courses. I wasn’t lucky enough to have such an Engaging instructor in any of those classes. This guy is such a natural teacher! He makes things so interesting you pay attention to see what he’s going to say next. Wonderful videos!

As a person who’s had a colon surgery as a late teen and has been nearly 30 years with subsequent IBS for all these years, this presentation has been extremely helpful to understand what’s going on in my inside. I’d love to have a consultation with Sean about my gut health issues as second opinion.

Hi! I am a retired PACU RN, 28 yrs, and I really enjoy your teachings. It refreshes what I learned in nursing school and even more. I have been following your videos and find them both interesting and refreshing for my memory. The facts are they squash a lot of the home remedies and junk on media that people get indoctrinated with. Thank you for your professionalism, the videos and also the people who donated their bodies so we may learn about human anatomy! Diane, RN, BSN, Cullman. AL.❤

I wish every teacher was as clear, concise, comprehensive, articulate, and engaging as you. I struggled every second through biology, and chemistry, throughout school and here I am watching your videos and am mesmerized. I really appreciate these videos. Thank you.

How to detox: 1. Have a functioning liver 2. Have a functioning kidney

who also watched it while sitting on the Throne? 😂

This guy fascinates me he explains so much so clearly in a short time and makes it interesting as well and may I add he is very easy on the eyes as well😍

video idea: what is an itch? for example, the sensation, the cause, how the scratch relieves it. Thanks for all this awesome content!!

not too many people can talk about poop for 18 minutes and be adorable all the while. It doesn't matter what your subject matter is, I love watching you and your videos!

So so informative!! Easy peasy to understand and I love the myth buster aspect! Now that I have a visual of the 20lb and 40lb weight the crazy claims of that much waste accumulating in the body is ridiculous!! Thanks for the great work and conversation!! Cheers to your success with the channel!

This guy is a really amazing teacher. I get so much from these videos! It's really great to have them to learn from.

Oh man…I was born with Hirchsprüng syndrome. I made 30 Surgeries on my large intestine. Used colostomy for two years, had 80% of my large intestine removed at the end and now I’m fully healthy. I still have some constipation but nothing really bad. In 17 minutes you made me understand everything that happened to me more than 7 years of treatments with I don’t know how many doctors…Thank you for this video man. Now I know what happens inside my body. For those who are wondering what my syndrome was…Basically you’re born without the Glya cells. These cells are located in the intestines and they’re responsable for telling the brain to make these movements. If you don’t have these cells your intestine doesn’t make the movements. And I was completely full all the time. For years. I discovered it when I was 22.

I’m learning about my body through watching these videos. These videos should be shown in high school. I feel it is a lifetime of useful information.

Thank you for such an in-depth explanation!! I’ve suffered with constipation all my life, so it helps a lot to be able to see all the parts as they actually are! I appreciate the work you all do!!

I wish every teacher professor were as precise and clear as interesting as you. Very clear and engaging. Thank you ❤🧠

We once had a senior RN, decades of practice, who remarked excitedly upon “The longest uninterrupted stool I’ve ever seen!!” after she gave laxatives to a client. A real “bowl-filler!” Nurse was quite amazed, happily. Client was relieved!

This is fascinating. Makes me wish so much that I had a normal bowel like he’s explaining. See, I don’t have my own small intestine or about six inches of my colon. I’ve had two small bowel transplants. The first was in 2000, but I rejected it 9 months later. My second was in 2002. I can never explain how grateful I am to my donors and their families for allowing their loved ones to save another human being during their own tragedy. I understand this on a very personal level-from both sides. I was widowed when I was 24 years old and pregnant with my first child. My late husband was a huge proponent of organ donation. He helped save and improve the lives of 18 people. It was the only solace I had in his death. Donors are true heroes. I’ve had over a dozen abdominal surgeries and after my last one, when I got both a small intestine and a kidney, they were unable to reconnect my stomach muscles. Because of this I am able to see all the peristalsis that he’s talking about. I have to physically push on my intestines to move feces through my intestines as my own peristalsis isn’t what yours is. Pooping once a day would be a blessing. For me, it’s up to 20 times a day, and consistently diarrhea. I don’t absorb all the nutrients and almost none of the water in the bowel. I have a permanent port in my chest that I must hook up iv fluid to every day in order not to die of dehydration and destroy my one kidney, which isn’t mine and doesn’t work that well either. But all of this doesn’t really matter, for I am alive twenty one years after they gave me two weeks to live. I am a mom still and my daughters have not had to mourn my death. They have been very afraid, as I’ve spent years in the hospital in total and have flatlined on the table many times. But I’m here today and I appreciate this beautiful world, my doctors and the discoveries in medicine that have kept me going. There are still many people, including doctors I’ve seen, who’ve never heard of a small bowel transplant, but thankfully it’s becoming more common. They’ll learn a lot from my body when I die, and it’s my wish that the knowledge gained will eventually help save the lives of others. Thank you for doing this video. It’s a great opportunity for people to learn about what I see everyday.

Brilliant channel! You guys are excellent educators!

Just wanted to say this has become my favorite channel on RU-vid. I don't have anything to do with all this anatomical information, but I can't get enough of it.

That annoying “toxic poop” guy just got served.

Using so many of your videos with my children - we homeschool and this better than any anatomy book I can find Thank you ☺️

This was so very informative. Your teaching skills are amazing.

You're the best explainer of all things medical that I've ever been fortunate to have encountered - thank you very much Dr. Jonathan!

I don't have a gallbladder and this was very informative about what happens without one. My mother's body was donated to science after her death because she was diagnosed with a cancer they couldn't identify. I hope they know what it is now and can help others before it's too late.

Take that, you silly "toxic sludge" ads! XD The bowel prep sure makes you FEEL like you're losing 20 pounds of weight though! LOL

Love your channel and the way you guys explain everything to us regular people. You guys are awesome 👍🥇

I found your channel and love the way you bring the medical terms to basics so I can understand what you are saying. I followed you... great video!

Seeing this demonstrated on an actual cadaver is incredibly eye-opening and instructive. Thank you SO much for making these videos!

I really enjoyed this video. I'd like to see a segment done on Lactose Intolerance and or people who aren't able to digest Gluten. Curious how the body responds on the inside this happens and how it processes the food. Great job!

So glad you talked about this and so glad for this channel!!!

Excellent demo here will pass this along to my nursing friends. Thank you for all you do...

When we learned this things at school, I did not understand a single topic lol. But now I really enjoy and understand everything, not that I know every single parts and process he's talking about, but it's a lot more easy to understand as he breaks everything down to steps, and explain it in concise definition but still comprehensible. Love this guy! I'm learning again.

Man donates his body to science "I will help cure diseases." Winds up getting his head bandsawed right down the middle and then someone digs through his intestines on YT and shows off his poop.

Excellent presentation. Thank you for clarity , concise information

This is an amazing channel. Thank you for taking time to teach us. I work in GI and everything you mentioned is 100% accurate. The better patients prep for their colonoscopy, not only will help us but will help with early detection of colon cancer . Thank you for this video

When my nephew was a National Guard member he would let me read the Army Survival Manual. It would always mention that bowl movements require an increase of water and that increased amount would have to be maintained before and after said movement. Always drink that water!

“That brown color we know and love” Well love is a… strong word

Simple and easy to understand. Well done 👏 beautifully presented.

I wish there were videos like this when i was taking all my anatomy courses in college! This could have helped tremendously!!

I would indeed be alarmed if I had 20lb of stool backing up so hard with so much pressure that literal nuclear fusion could convert the carbon into iron and press it into a 20lb dumbbell shape XD

The body is an incredible machine that does almost everything without our help.

Love your expertise and pacing of your explanation of everything. Your communication skills are excellent. My bowels and intestines are of great interest to me as I've had issues for several years and only recently they have started to normalize. Thank you for this video.

Amazing, intelligent presentation!👏👏👏

I’m 74 and found this video so interesting. I learned so much. Great teaching session and of great interest to me. Thanks for the clear explanations and your love of the subject matter!

I was not prepared for the whole "It starts when you put food in your mouth, let me show you on this actual severed head" bit at the start

Wow! You are so clear, informative, and wonderful to listen to. Thank you so much for your posts! I have just subscribed and am very glad I found you. Thank you for what you do!

Always enjoy watching and listening and learning from you. Very candid and objective!!

Just found this channel. Absolutely LOVE it. I never took an anatomy class in high school, and college was not in the cards for me. At nearly 70 now, I am totally stoked that after viewing just one of these videos, I am COMMITTED to watching several every single day until I run out. Then it’s possible I’ll begin again. Such a great format. A clear and detailed presentation. The instructor is perfect. Thank you for this site. 😊

As someone who has dealt with some level of constipation my whole life, though particularly bad in the last few years, this is the stuff I wish people had explained. This helps me better understand what's really going on.

Thank you for explaining it as simple and clear as possible. I love your videos. They’re very informative and helpful.

Amazing info buddy!!

15:47 The reason why the colon looks squeaky clean is because we advise patients to take laxatives and have a certain diet is possible before the actual procedure. But it is normal to find some faecal matter during the procedure. But you can always tell if the patient hasn't followed the prep advice with amount of faecal matter in the colon

It would be interesting to see an explanation of diverticulitis.

Thank you for explaining a complicated subject so clearly.

Thanks for sharing I am so fascinated with these information you posts.

“Conglomeration of Guts” = best death metal band name EVER

Thank you for talking about this. You’re a good doctor! I went to a doctor in my twenties because I wasn’t having BMs for more than a week, and when I did, they were like rabbit droppings because I was so constipated. He told me to take a laxative. I asked him how big did my stool should be for him to consider it a good BM? He actually laughed at me and said whatever came out was good. I was furious and never went back to another doctor for years. You see, Mega Colon is a condition many in my family suffered with. At the time, I took the laxative like the doctor said, and, Oh My Gawd, I’d never do that again. I cramped so much and rolled around in severe pain on my bed sweating, before the laxative had time to work all the way down to release!!! My brother, son, and grandson had Mega Colon which produced what I called, “SUPER HUMAN STOOL!” Their BMs were equal in length and circumference of having a baby! Which I would like for you to talk about on here! It is dangerous, as well as, embarrassing for the person who has it. My brother still soiled his underwear until he was 18 yrs old, and had huge bumps like acne, only worse, on his face and nose. He was shamed by my mother until he tried to hide it from everyone. This can’t be hidden, and it’s not their fault! At around 4 yrs old, my son had dark circles under his eyes and a noticeable bloated stomach. He would come in from playing sick and sweaty. I made him rest until he felt better, but I was worried, so I took him to the doctor. Doctor said he was fine and probably had a bug going around. Finally, at 8 yrs old, he began to get a rash all over his body. I thought he was allergic to something and took him into the ER. They gave him a Benadryl shot and sent us home. I knew in my soul something else was going on. The Benadryl didn’t do a thing, so I took him back to the ER. Hallelujah, there was a great Doctor there named Dr. Justice! He immediately had an X-ray done on my son and finally told me what the rash was, and why my child had red blotches all over his body. For those who are going through this same thing, here was what I was told. Dr. Justice said my son had Mega Colon, which I’d never heard of. My sons colon was so packed with huge stool, that his colon wasn’t able to flattened out before, and after, stool moves down, and the colon will then stretch out which gives us the feeling that we need to expel our stool. The colon just stays wide open, therefore, allowing stool to drop out at anytime. He was enacted and is what caused the “super human size stool.” So, from the stool being caught up in the colon so long, and getting bigger, those toxins began to be released through the skin, causing the rash. I didn’t understand why my son, as well as his uncle, were still soiling their underwear at their ages until then. Dr. Justice told me to begin giving my son 2 tablespoons of mineral oil daily with plenty of water and juices. He said it would take about a years time for the colon, which had been stretched so large, to shrink back down to normal flatness so that my son could feel the normal stretching out of the colon for a normal bowel movement. The first question Dr. Justice was asked me was if his stool was unusually large. On my goodness yes, I said! Well, I know this was a long story, but well worth the time reading if your loved one suffers from mega colon. That very night I called my brother, who had just taken 2 laxatives, which Dr Justice said to never give to my son until this was cleared up completely. The laxatives caused my brother to pass out in the bathroom, and my sister had to help him come back around. I told my brother all about taking the mineral oil for a years time with water and juices. Literally within a year or so, they both made a complete recovery! No soiled underwear, which made them both very happy. My brothers face cleared up with no bumps or acne. My sons rash went away as soon as he began expelling the toxic stool. All of that old stool was making my son sick, bloated, and toxins were secreting through his skin. After that, I was able to notice it right away with my grandson and got him right on the mineral oil immediately. All turned out well, but I did research this Mega Colon, and it is genetically passed down. People have died from it. There are images of the size the stools can grow to be and killed the man who had the largest ever seen. This is a worthy topic to talk about to make people informed. Thanks for reading.

Great description. Thx for the info!!

At the 9:10 mark, learning about Mass Peristalsis, was very enlightening. I often take a large salad to work for lunch and often found I'd be needing to visit the bathroom rather urgently around the end of my lunch break. It got to the point I asked my doctor if I had IBS. Unfortunately it would be trial and error to know what food (part of the salad) was causing this. I don't recall getting this urge after most other meals. But thank you for explaining why this occurs. BTW, I wish you gave a timeline on how long it takes from eating to when it exits the rectum - out of curiosity.

Human body is like a fascinating machine and btw I love watching your videos, they are very informative.

When my eating disorder was really bad I didn’t have a BM for 3 weeks…it was horrible. Ended up taking laxatives for around 3 days to get it all out. Don’t remember how much it was but it was so painful. Also a note if you haven’t had a BM for a long time, for any reason, please go to your doctor! I didn’t because I was ashamed and hiding my ED but it could have ended really badly if I hadn’t used laxatives (which isn’t that safe if you have an ED). Thanks for the interesting video!

Truly gifted. Fab educator/communicator. Hi praise.

This was an excellent segment, per usual.

Just subbed. Can’t believe I didn’t know about this channel sooner! As a future Doctor this is a nice way to just relax and learn. Thank you so much for what you are providing, and thank you to the people who donated their bodies to science. 🙏🏽

Eat a bag of cherries, eat a bowl of shredded wheat, then drink a bottle of tart cherry juice.. You'll crap out things that you haven't seen in years

You are an absolutely wonderful teacher. If every teacher was as clear, concise , and engaging as you are, well eduction in general would be so much more effective. You can tell you really care and are genuinely excited about what you are explaining, and it makes it enjoyable. On top of that you have articulated everything in such a way that is very easy to understand and in turn it makes more retainable. You'd do really well as like an adults version of a bill nye type situation where you teach different medical sciences. I would tune-in in an instant, and I know my fellow ~30ish year olds would just adore being able to watch something similar to bill nye and learn again.

THANK you so much for explaining the whole "toxic sludge" thing. People are so reluctant to believe this, which is great for the "cleanse" industry but just not consistent with reality. I'm a retired NP who spent hours in my career explaining this to patients. Now they can just watch your videos.

*It is such a relief to hear medical facts being spoken and none of the crunchy mlm nonsense.* *Thank you, it is beyond refreshing and deeply appreciated.* 🙏🏻

You guys are brilliant and this channel is simply FASiNATNG!!! Keep em' coming!

I had colorectal Cancer stage 4 in the year 2000 I learned alot in this video love this Channel

Now whenever I poop more than once a day, I'm going to refer to it as an "added bonus poop."

Great presentation. Clear, concise, and easy to understand. You’re also a very good speaker, which helps to stay with the video till the end.

Very informative, amazing presentation!

Very informative and easy to understand!

My favorite facts about the digestive system is how the intensities wiggle and squirm. Like, a lot. Apparently it often freaks people out the first time they see it.

True story. I was blocked up when I was in my teens for nearly 3 weeks. I didn't know about laxatives and I never told my parents of my problem cause I was super shy and insecure. 1 day during a camping trip with family I decided it needed to come out no matter what. I knew I had to atleast force it out. I remember walking to the washroom at the campground mustering up my courage to get whatever was in me out. This was not going to be just a "pinching of the loaf" but more of taking a chainsaw to a 3 week old bread nobody wants to eat... I went into the stall, sat on the porcelain throne and then pushed as hard as I can..... And I grunted and grunted till I saw blinking stars shooting out from the washroom stalls door. It felt like I was going Lightspeed on a star fighter... I had FELT whatever was in me come out after a minute of continuous grunting.... And after that I had reached euphoria... And at that moment I knew, I was a new teenager. I wanted to know who my match was before I flushed.. and as I was wiping I made sure the toilet paper was off to the side of the bowl to get a view of my big brown creation.... So as I stood up and looked behind me into the bowl, I saw NOTHING but toilet paper!!!!! To my amazement I was thinking why? What is going on? Is this a hoax? Is God playing tricks on me? After a few seconds knowing nothing big and brown was there I flushed the toilet..... And at that exact moment I flushed, the water started to rise and it was not flushing as it should! Water started to spill off the sides and I quickly B-lined it out of the washroom not even thinking of washing my hands... Till this day I would NEVER know what came out of me or if anything did... But the only proof something big and brown came out of me was that I plugged the toilet. I apologize to the janitor who had to clean up my mess.

Loved the explanation ❤❤

A very informative presentation…thank you. How does he do it without any hesitations or waffle. If he had a cue screen then he is the ultimate professional speaker as well as a consultant!! Wish I had this briefing before my bowel cancer ops 16 and 6 years ago.

i always thought it was common sense that the intestinal tract couldn't have 10 lbs or more of poop at any given time. seeing all these "health claims" being spewed about it concerns me because i wonder what constant ingestion of laxatives does to the gut. i'm glad he broke it down especially showing the weights.

Amazing video. Could you do a short adding to this talking about what causes IBS and stomach aches. Also would love to learn more about the bacteria in the large intestines, aka the poop chute.

I love your "Show and Tell" teaching strategy.

Beautifully explained.

Sitting here, getting ready for my colonoscopy tomorrow, I really appreciated your frankness and facts. Thanks.
