😳 Uncontrolled IBS is not good but then you get a flare up on top of this.

😩 The natural thing to want to do is avoid all food, all fiber and go bland diet for a while but that doesn’t really work and can actually make things worse.

🙋‍♀️ Instead use this science backed approach to gain back control.

😩 Relate?

➡️ When you get instant urgent or loose stools after eating it is normal to think that it is just what you ate but that’s not the truth.

➡️ People worry that they are having malabsorption and will end up with nutritional deficiencies but this isn’t the case in IBS.

✅ Foods take hours to pass through your gut so what you are experiencing is likely fueled by your gastro-colic reflex and what you ate yesterday and your stress levels etc - there are many factors to unpick.

👀 Can you relate?

➡️ The truth is that constipation isn’t defined by how often you p**p but what that stool looks like, how easy it is to pass and how empty you feel after.

➡️ IBS constipation can be caused by a combination of factors which is why it’s important to target those factors vs just focusing on generic gut health advice of fiber and fluid only.

👀 This is the biggest misconception I see people make when they seek the help of a dietitian for this IBS… they think that a dietitian will take out foods and identify the food that’s causing the issues.

😅Now yes sometimes we do do that but the issue is that a lot of people with IBS are already avoiding all the potential culprits plus a random list of other foods due to misinformation online or misinterpretation of their own diaries.

🙋‍♀️ So in many cases I actually end up adding foods back into the individuals diet rather than restricting further.

➡️ Food is often an issue in IBS and some (not all) people have food intolerances but it isn’t the only issue and that’s why a restriction only approach isn’t going to give you the control you so badly need.

👀👀 It’s an easy thing to overlook but this is an issue I see all of the time.

🤝 A vegetable soup makes the perfect healthy lunch until you realise it contains hardly any calories.

➡️ When we don’t consume enough calories our gut slows downs.

😅 Surprisingly many soups actually don’t contain enough fiber either so do check that!

🙏🙏 This does not mean you can’t have soup but it does mean you need to add something to it - aiming for at least 500 calories (often much more if you exercise and are under 50).

➡️ How many people have their mornings dedicated to the toilet before work? 😩

🤝 Once again, when you understand the science you can start to apply it to your sensitive IBS gut.

Does this new study mean we should start using IgG food intolerance tests for IBS? 🩸

The results are interesting, and I don’t think they should simply be dismissed.

But showing that an IgG-guided elimination diet improved one outcome does not prove that IgG has correctly identified someone’s food intolerances.

There are still some big unanswered questions, particularly around differences in FODMAP and fibre intake between the diets, whether IgG positivity actually identifies a symptom-triggering food, and what happens when those foods are reintroduced.

This matters because unnecessary food restriction isn’t harmless. With IBS, our goal should be to identify what actually triggers YOUR symptoms while keeping your diet as varied as possible.

So yes, this study has made the IgG conversation more interesting.

But no, I’m not recommending IgG testing to guide food elimination in IBS based on the evidence we currently have.

😳 It can get like this in IBS when it feels like everything you eat can cause symptoms.

🙏 But please note this is not the case at all.

➡️ Foods can cause symptoms depending on the amount you eat, the combination, hours afterwards, if you are constipated.

😅 And sometimes symptoms are not even due to food at all.

😩 Looking 6 months pregnant by the end of the day is normal when it comes to uncontrolled IBS.

➡️ But the cause is not 1 thing. It could be many things.

👀 TBH I usually have to use several techniques with clients because there distention is caused by many things.

✅✅ Target a combination of what I have mentioned in this video.
