The Miraculous Irritable Bowel Solution

by lydia on April 9, 2015

Irritable bowel syndrome is a silent disorder. Silent because sufferers don’t want to humiliate themselves by talking about their bowel troubles. Yet, the lives of 12-15% of the population globally are conditioned by this terrible affliction. Probably more like 20% in the western world. That’s one in five people.

If you have IBS, you will know the pain of trapped wind, the discomfort of bloating and the embarrassment of your dependence on knowing the location of the nearest toilet. IBS sufferers are split between those with diarrhoea (the majority), constipation and those who swing between the two (the minority). But all have lives that are dominated by IBS.

The mechanism of what causes IBS is unknown, and there is no cure, but they do know that the brain to gut connection is faulty, and distorted signals are sent from the brain to the gut which behaves in a hyper-sensitive way.

Until now, there has been no solution for the misery of this large group of people. Doctors have thrown a plethora of different medicines at them, which gave temporary, minor relief but left behind even more problems from their side effects.

But, now we have the low Fodmap diet – a magical, life-changing diet which can completely eliminate IBS symptoms. In fact, it has been scientifically proven by the research centre at the Monash University in a double blind, quadruple-arm, randomized, cross-over, placebo-controlled rechallenge trial to significantly reduce the symptoms in 75% of those with IBS. That’s massive.

So what is this diet?



These are all poorly absorbed short-chain carbohydrates, which basically are indigestible sugars.

In IBS sufferers, some or all of these sugars are poorly absorbed in the small intestine and excess travels on down into the large bowel where the anaerobic bacteria feast on them causing fermentation, resulting in bloating, trapped wind etc.

It is impossible to eliminate all Fodmaps from our diet because we would die of malnutrition, but we can limit our intake of them by consuming only those with a low Fodmap content. By doing this in a careful and calculated way, symptoms become negligible.

The Elimination Diet

During this phase of the diet, you eliminate all high Fodmap foods and eat only those low in Fodmaps. Once your symptoms are gone (this could take anywhere from 2-6 weeks), you move onto stage two (see later).

But make no mistake, this is a complicated diet. It is not a matter of excluding one thing from the diet like gluten or lactose. It is about controlling the amounts of Fodmaps consumed. A list of good foods and bad foods is only one of the puzzle pieces and, by using that alone, the diet is sure to fail. It is a diet of amounts, combinations and accumulation of Fodmaps throughout the day. On top of that, we are all individual, and our absorption levels are different to anyone else’s. Finding the perfect balance is tricky. We are given (by the Monash University) the average amount we can eat of the low Fodmap foods but these are exactly that – an average. For example, we can have one banana but you might find you can tolerate only ½ a banana before symptoms begin.

The Reintroduction Stage

During this phase, foods from the individual groups are tested carefully and systematically to find the perfect final diet for the individual.

It is rare for someone to have problems absorbing all the Fodmap groups. For example, only 45% of people with IBS malabsorb fructose and 25% malabsorb lactose. You may only have major issues with one group, say fructose, and be able to absorb certain amounts of another Fodmap group, say polyols, and have no trouble at all with another group, say lactose. You will discover this during this stage.

Something you have to be aware of when you try this diet is that it has to be done 100% or not at all. Even one high Fodmap food will cause symptoms and muddy the waters. This is not something you can dabble with or introduce slowly, or you will think it is not working. Many people give up on this diet before they get it right and so leave behind a diet which could have saved them.

Are Fodmaps the complete picture?

There are a few other gut irritants that you have to be aware of when you do this diet even though they don’t involve Fodmaps.

  1. a) Fat – every cell in our body requires fat to survive, but it can irritate your gut at too high an amount and cause symptoms. We are all different, and you have to find the level that you can cope with.
  2. b) Alcohol – this is also a gut irritant and completely unnecessary in our diet. So, it is best to limit it or eliminate it completely.
  3. c) Excess gas intake – the gas in carbonated drinks irritates the gut and should be avoided. Smoothies are also questionable because of the large quantity of air that is pumped into them during their making. Also, it is best to eat with your mouth closed and to avoid talking while chewing so that no air is ingested.
  4. d) Caffeine – this also irritates the gut and should be avoided as much as possible.

3) Fibre – fibre is essential for a healthy diet but too much will irritate the gut and cause symptoms. This is one of those individual things where you have to push against that fine line between having enough fibre to keep things moving along well in your digestive system and not causing symptoms like bloating.

So, this will not be an easy journey but it is a journey, if followed meticulously, which will give you enormous relief from your IBS symptoms. It is truly a miraculous diet.

Hi! Thank you for this.
It is interesting,, but I haven’t managed to get any relief from my symptoms by following the Low Fodmaps diet. The only thing that gives me some relief is a LCHF diet.
I do not know if that is beacause my symptoms is caused by something else than malabsorptions of Fodmaps, or if I did something wrong when I tried..
Would you say that there is a few Low Fodmap foods that is more or less “bulletproof”? A few that is the absolutely best to start with?
Also, sugar and sugary candy, how much of this is considered Low Fodmap?
Thank you! //. Patrik

Patrik April 12, 2015 at 3:54 pm

I need to admit also that I only lasted 4 days.. Maybe my symptoms would have improved if I had been on it for another 3-4 days?
I have been eating LCHF for so long now that just being “full” from food feels strange..

Hi Patrik. Good to see you over here at Lydia’s site. Unfortunately, 4 days is not nearly long enough to be on the diet to get results. If it is done 100% accurately, you can get reasonably quick results but it is hard to get it right straight away. You will know from my videos and blog posts how complex it is as a diet. It is a diet where it has to be accurate or it doesn’t work. Even one wrong food will cause symptoms and negate all the rest of the good work you have done. You have to also watch your combinations of low Fodmap foods or you will create a high Fodmap cocktail that will cause symptoms. There can also be some foods that are an issue for you even though they are low Fodmap and that is an individual thing and you can only find those by doing the diet strictly. Please do give it another go. If you have IBS and not something else, then this will be your answer.

Hi Suzanne!
Thank you for your answer. I guess I might have overdone it with something.
I’m gonna really dive into to everything you’ve written again, and be more thorough and plan it more carefully, and then give it another try, for at least a week, next time. Once again, thank you!

I am very glad to hear that, Patrik. You might need more than a week depending on what type of IBS you have but the bloating should go down quickly if you are doing it right. Why don’t you keep in touch through the IBS Insider Club and let us all know how you are doing. Ask as many questions as you need to in order to get it right. Good luck.

Patrik April 13, 2015 at 1:00 am

I will do that Suzzane!
Thank you!
