âźď¸ Most probiotics wonât help your constipation! đ
đŠ If youâve been trying probiotic after probiotic, hoping this one will finally fix your constipationâŚonly to feel no different – or even more backed up – youâre not alone.
The truth? ⨠Most probiotic strains were never tested for constipation.
đ Hereâs my #1 rule as an IBS dietitian: Your probiotic must have clinical studies on people with constipation.
Most strains fail this test. But Bacillus coagulans Unique IS-2 (MTCC 5260) actually delivers:
đ 1 â 6 bowel movements per week (in 4 weeks of daily use)
đ 98% achieved normal stool consistency
đ Real published research (not marketing fluff)
đ Stop wasting time, energy and money. Start choosing what actually works for your symptoms.

I adore Taylor Swift â¤ď¸ but her comment on BBC Radio 2 this morning needs a little fact-checkingâŚ
đ Sourdough bread is not gluten free.
It is lower in certain carbs called fructans, which can cause bloating and gut symptoms â especially if you have IBS.
Thatâs because the fermentation process breaks down many of these carbs, making sourdough easier to digest than regular bread.
But gluten is a protein, not a carbohydrate â and itâs still very much present in sourdough.
So if youâve got coeliac disease or a gluten allergy, sourdough isnât safe for you.
Even small comments like this can cause big confusion â especially when they come from someone as influential as Taylor đ

Each week I do enquiry calls and speak to people who âarenât sureâ đ¤ if they have IBS or not despite having seen a doctor đŠââď¸đ¨ââď¸âsometimes multiple doctors.
Yes â
they have done tests.
But they donât know which tests exactly đ§Ş were done and the doctor has just said âit is probably IBS.â
This leaves the individual unsure of what the next steps are âĄď¸ Do they need more tests? đ Do they need to see a specialist? đĽ Is it IBS or not?
Now the truth is that when I review most peopleâs history (their onset, symptoms, family history, lifestyle and what tests have been done) â they do have IBS and we are able to make that clear diagnosis đ.
But if you donât have a diagnosis, it kind of leaves you âhangingâ there đ.
Some people even end up waiting âł months, if not years, to see a specialist in the hope of getting a new diagnosis but end up being told it is IBS anyway⌠when they could have spent that time tackling the problem đŞ.
And the larger issue I now see is that âprobablyâ comment đ, which provides a lack of confidence, coupled with an individual trying to manage their IBS alone, leaves them to believe that they do not have IBS because nothing has worked. They then waste even more time looking down alternative routes đ or thinking they have SIBO đŚ .
đ To check if you have IBS or not, check out my blog: https://theibsdietitian.com/blog/how-to-get-an-ibs-diagnosis
This blog provides all the tests đ§ž and the criteria needed for diagnosis â you can take notes đď¸ and check with your GP.
If you are on the Take Control course đ â you can simply download the GP letter from me and take it with you.

đŠDiverticular disease is estimated to impact 35% of the population so it is very common!
đ
The management of this condition is actually really simple from a diet perspective – a high fiber diet with enough fluid. And if you get a flare up then you want to avoid fiber to allow the gut it settle whilst you take treatment.
đŠ But I see a lot of confusion when it comes to people having both diverticular disease and IBS.
đŤ The issue is that firstly people keep getting inaccurate guidance on diverticular disease such as being told to avoid seeds and pups and then being given 1 diet sheet as they leave the hospital telling them to avoid fiber. The avoidance of fiber bit is only needed when you are in an acute flare up, for long term management, the opposite is needed.
đââď¸ But then comes the question – how do you consume a high fiber diet for one condition when your IBS makes it really difficult to tolerate this?
𼳠There is a way forward. You do NOT need to be consuming 1 diet for diverticular disease and another for IBS. You need to know what your IBS triggers are so you can consume a high fiber diet without the IBS triggers. And working on other areas will also make you tolerate more foods and so actually it becomes easier with time to follow that higher fiber diet.
đŤ I would love to know if you relate to this story?

đ Goodbye September – canât say Iâll miss you đ
.
đ Photo collection from a rather rocky start to September but with some positives along the way.
1ď¸âŁ So happy that autumn fashion is now in! Plus loose trousers which are so good for my fellow IBS crew!
2ď¸âŁ Our September started with a stay in the ICU for Esme đŠ. Luckily she is 100% fine now and bouncing around.
3ď¸âŁ A paper I helped write on histamine intolerance was published 𼳠in a peer reviewed journal.
4ď¸âŁ A nice surprised popping into @magrudys to see my book amongst the best sellers.
5ď¸âŁ Had a great morning with @great.little.eaters where we had a catch up and then helped each other make content for social media. I donât think either of us will make great influencers any time soon đ
đ thank god we have qualifications đ.
6ď¸âŁ PT sessions continue with @thefitmidwife.
7ď¸âŁ I went viral across several media platforms talking about how a pumpkin spice latte could be an IBS trigger.
8ď¸âŁ and 9ď¸âŁ School drop offs = early starts and serious heat
đ Finally I get back to BJJ @studio100bjj đĽł.
â¤ď¸ Roll on October. But please be less hectic đđ

Did you know Vitamin D deficiency is strongly linked to IBS symptoms? đđ
âĄď¸ Adults need 10 micrograms per day â usually from sunlight and small amounts in food.â¨âĄď¸ UK guidelines suggest everyone supplement in the winter.â¨âĄď¸ But hereâs the kicker⌠even in sunny places like the UAE, deficiency rates are still super high!
For IBS, the stats are even more shocking:â¨đš Around 20% of the general population are deficient.â¨đš But in IBS, that number jumps to 67%.â¨đš Research shows correcting this deficiency can significantly improve symptoms. đ
đ Hereâs what I recommend to clients:â¨âď¸ Consider a daily supplement of 10 micrograms (400 IU) year-round.â¨âď¸ If you have IBS, get your Vitamin D levels checked.â¨âď¸ If deficient, youâll likely need a short-term high-dose supplement, followed by a maintenance dose once levels are back to normal.

Histamine intolerance
đ So pleased to see my first published paper.
đ¤ŻHistamine intolerance is a very tricky area to navigate so I was delighted to contribute to this project and review the research available. If you have a science background then you can check out the paper here: Int. J. Mol. Sci. 2025, 26(18), 9198; https://doi.org/10.3390/ijms26189198
đââď¸But for the vast majority of you who do not have a scientific background I will summarise below;
* Histamine intolerance occurs when someone is unable to break down histamine we find naturally occurring in foods and also histamine which the body naturally produces. The build up leads to a range of symptoms.
* Symptoms range in type and severity but include – GI symptoms, sinus problems and even urinary issues.
* There are no accurate tests currently available.
* Diagnosis is made a lot like IBS in that routine tests to rule out other conditions that symptoms could be linked to are done first. This is done alongside the individualâs presentation in relation to fitting with histamine intolerance. AND then only if that personâs symptoms improve on restriction of histamine and come back with reintroduction do we make a diagnosis.
* There is no one accurate list of high histamine foods which makes it tricky to navigate. Instead âbest practiseâ is often applied.
* Research showing oral DAO enzymes to be useful is limited but they are worth trying to help expand a personâs diet.
đIf you have any of these symptoms, please check in with your doctor rather than trying to self-manage. Your symptoms may be due to a number of other conditions which need medical treatment.

âźď¸Yes IBS can involve food intolerances but there is no current food intolerance test that exists.
đ§We can not test for food intolerances because they do not involve a single pathway in the body which can be tested. Instead, food intolerances involve several pathways – some we do not yet understand.
đŠSadly, there are a number of scams out there which promise you this lovely neat report of your food intolerances based on various testing but none are accurate – to the point that if I advised a client to take one, I would lose my license.
đSo please, I know it is super frustrating but do not waste your time or money on âfood intolerance testing.â
