IBS symptoms, the low FODMAP diet and the Monash app that can help

Medically diagnosed Irritable Bowel
Syndrome, known as IBS is difficult to treat and overcome. In part, because we
still don’t understand its precise cause. However, researchers at Monash University have been studying the dietary factors in food that can trigger IBS symptoms.
This research has shown that the pain discomfort and daily disruption caused
by IBS is triggered by certain types of carbohydrates in food called FODMAPs.
Here we can see some examples of high FODMAP foods. To understand how some foods contribute to IBS symptoms, we need to look inside the intestines where food
is broken down and absorbed. Zooming into the molecular surface of the intestinal
cells we see they are covered in molecular machines that accelerate the
breakdown of carbohydrates. Most carbohydrates, once broken down, can be absorbed through pumps on the surface of your cells. However, some carbohydrates are not digested or absorbed by people. The rapidly fermentable short-chain
carbohydrates that can’t be absorbed are called FODMAPs. The presence of FODMAPs causes water to be dragged into the small intestine. Also, because they aren’t
absorbed, FODMAPs travel through your gut to the large intestine. When
bacteria in your large intestine get access to FODMAPs, they use them
for energy to survive. The bacteria rapidly ferment FODMAPs and produce
gas as a result. Excess gas production and water retention causes the intestines to
expand. When the intestinal wall stretches from
distension, the highly connected nerves around the intestines send signals to
the brain. People with IBS have very sensitive
intestines, so these signals contribute to the pain they experience. To reduce
FODMAP intake and to alleviate the distension, bloating and other symptoms
of IBS, Monash University have developed the low FODMAP diet. People with medically diagnosed IBS should consult a dietitian about trialling the diet. The Monash
University Low FODMAP Diet app has been developed as a tool to help people with
IBS manage their diet and alleviate symptoms. Contact Monash University or
visit the website to find out more about the low FODMAP diet.


  1. I sent this simple video on a complex subject to my family so that they would have a clearer understanding of my health situation. Thanks for creating it. Excellent tool for sharing.

  2. You are saving my life!! Thank you very much!!!

  3. My favorite part is the visualization of the gut microbe releasing gas, and how it causes bloating and abdominal pain. Nicely done!

  4. I love this video!

  5. Really great explanation – I'll start using this with my patients.

  6. The app is FANTASTIC! DON'T HESITATE TO BUY IT, it is worth every penny!

  7. Excellent explanation!

  8. thank you. What a great informative video and delivered in such an easy to understand format.

  9. You're life saver

  10. interesting!!

  11. What an incredibly well animated video!

  12. 'People with IBS have very sensitive intestines'. Where is the evidence for that? I presume IBS is usually of unknown etiology, so how can you say one person experiences more pain in their intestines than another when you don't really know what is causing it?

  13. This needs more promoting, my GP recently suggested I look into the FODMAP diet. As I've suffered with IBS for over half my life I can honestly say it's amazing to eat without experiencing discomfort/bloating/pain after. I'm a vegetarian and always felt I was eating a healthy, mainly plant based diet… I now see the error of my ways using onion, garlic and mushroom in most of my meals. I've tried a gluten free, wheat free diet but never felt the relief I feel now. It's ashame I didn't discover this sooner! Thanks again 🙂

  14. There are bananas in the bowl to the left. Aren't bananas low in fodmaps?

  15. pumpkins is low fodmap, isn't it?

  16. Hey guys – I made a video about my personal journey on the diet and the incredible results I've had if you're interested its here: https://www.youtube.com/watch?v=T_cryzBXSJg

  17. This diet has given me the ability to work, play sports, and do everyday activities with my family… things that I was literally unable to do 2 years ago because of the effects of IBS (pain, extreme fatigue, weight loss).
    The Android app is great reference tool!
    Yes, I still have a bad day here and there, but they are manageable.

  18. why would people downvote this video? Monash uni is saving lives.

  19. Why is this app so expensive 🙁
    almost 30 PLN…

  20. On a chart on the website it says bananas are low but in the video they are shown as high!!!???

  21. Thank you Monash , for ending my 8 year nightmare.

  22. Thanks a lot.

  23. Damn… £5.60? Bit expensive..

  24. Only 6.66 EUR? Bought!

  25. Brilliant work. Great educational introduction.

  26. Hey Chris saw this on 730report tonight, thought I recognised it. Looked great!

  27. Great visualization! On the app, is it possible to get a graph of BM history over time?

  28. My son missed 5 months of school with out of control IBS. Finally found a pediatric nutritionist who worked with us to change his diet to low FODMAPs (no one else even knew what this was). 2 years later, he's 12 years old and you would never know that he had such horrible problems. He knows how to "test" foods that are new and has successfully been able to add many foods back into his diet, some completely and others with limits. Life changing for him and the family. I just wish more American brands were tested. Thank you Monash University!

  29. If basically the entire small intestine and large intestine is affected, why do I only fell pain in the lower gut, just below my belly button? Also, I was under the impression that most of the pain comes from the large intestine where undigested stuff is eaten by bacteria which give off gas and other substances that cause the pain.

  30. I wish I could eat a low FODMAP diet, but I'm only 13, so I have to eat what I'm served…😭 I eat healthy, though, and that has definitely helped. Also I try to avoid dairy.

  31. Thank you thank you so much!! i am so happy that i found this app!!!!!!!

  32. Thank you! This diet has given me instant relief to crippling pain

  33. Definitely purchase the Monash app. Hugely helpful as a quick reference to high fodmap foods. For LoFo recipes, check our @LoFoFoodie on You Tube of Facebook. Videos of meals and snacks that support a LoFo diet.

  34. Amazing animations!

  35. Hi I've had ibs for a long time now I've basically tried everything I also had a igg test for celiac disease which was normal and also took antibiotic rifaxamin which didn't help at all and every food that I eat gives me discomfort (ibs symtoms) what I want to know is that is this app helpful because my doctor said he can't do anything and I'm out of options.

  36. So no apple a day keeps the doctor away.

  37. 0:17 what a bad actor hahah, great video though

  38. raw vegan fodmap diet
    truely difficult

  39. This is an amazing video I'll be showing my patients who consults for IBS symptoms … which are quite a few!

  40. The diet helped me a lot. I am on it for 6 weeks and no way I am going to come back to old habits.

  41. What a tremendously well-made, clear video! I recommend it to anyone with IBS or just curiosity. The title "Grand Tour Down Under" is perfect too.

  42. Guys,eliminating foods with a specific FODMAP one at a time might make things easier.

    I am not diagnosed with IBS, and may be slightly sensitive, but certain foods made me uncomfortable years ago and i tried to fix it myself, tried looking at low FODMAP thing, i got some apps that listed what foods "in general" were high FODMAP but it was too restricting because it was too general, a lot of things were high fodmap leaving me with practically nothing to eat lol and then i knew i definitely didn't have any problems with some foods that were meant to be high FODMAP.

    I Recently Found an app called FODMAP A to Z, and i noticed it listed the type of FODMAP the food was high in (any app where they tell you SPECIFICALLY what FODMAP is present in that food will do, like the Monash one, but it's more expensive) and now i can stop walking around in the dark, i looked around the app for a bit and and found the foods giving me issues were high because they ranked high in the Ogliosaccharide content (the O in FODMAP, Fructans and Galactans). then to test my theory out i looked for high FODMAP foods that i knew i had no issues with and hypothesised that they were not high in Ogliosaccharides but another FODMAP, sure enough, they were high FODMAPs because of Monosaccharides(Fructose) or Polyols but NOT Ogliosaccharides.

    Now i'm just excited that i don't have to eliminate everything under the sun… annoyed about cashews though… i started paying attention to everything i ate a few days ago (the bloating got really terrible these past few months after i went takeaway crazy and decided i was going to start eating healthy , nuts seeds and so on) and i noticed a funny/bloated feeling after eating cashews… i checked the app hoping and praying and damn it, cashews have ogliosaccharides (T.T)

  43. I found a useful collection of videos that should help on Stomach oracle omnibus

  44. Those graphics are amazing.

  45. I'm a little late to the party but this video saved my life not even kidding thank you

  46. my friend has recommended this and she is so much happier since being on this diet.

  47. I was looking for an video to explain the Low FODMAP diet to a client. This is excellent! Thanks Monash. I do wish you would explore SIBO as well tho. I was on the LOW FODMAP diet for years to quell my symptoms, but it wasn't until I addressed SIBO that I really felt better.
