Hello and welcome to Bupa's Inside Health Series.

I'm Dr. Zoe Williams.

And today we're gonna be talking all about gut health.

What do we mean by gut health?

What things are good and bad for our gut and what can we do to look after our gut health?

It's a really interesting topic, but it can be quite confusing and a lot of the science is relatively new.

So I'm gonna be joined by gut health dietitian, Kaitlin Colucci and Iona Bell, who's a specialist dietitian at Bupa's Cromwell Hospital to help us uncover this really interesting topic.

So Kaitlin, let's start with where is the gut and what do we mean by gut health?

So gut health refers to the functioning of our entire gastrointestinal tract.

So that's everything from our mouth all the way through to the exit at the other end.

And its main function is to absorb nutrients from the food that we eat and rid solid waste from the body.

And it also hosts our gut microbiota.

So the community of trillions of bacteria which live inside our large intestine.

Now, for good gut health, there's no real universal definition, but I suppose it could be the absence of any unwanted gut symptoms like abdominal bloating, constipation, or diarrhoea.

And when it comes to our gut health, that also influences other aspects of our health, which will come onto, but what influences our gut health?

So the number one thing which influences our gut health is the food that we eat, in particular, the dietary fibre we consume.

So dietary fibre forms the backbone of all of our plant-based foods.

So our fruits, our vegetables, our whole grains, our beans and lentils and our nuts and our seeds and our gut microbes break down this fibre through a process known as fermentation, which produces all sorts of beneficial molecules, which gets sent all around the body.

And we should be aiming for about 30 grammes of fibre every single day because this has been shown to reduce the risk of certain diseases such as heart disease and type two diabetes.

And we hear more and more now about the gut microbiome.

We also hear that the gut is the second brain and it somehow communicates with our brain and impacts our mental health and it even affects our immune system.

So how is our gut having this huge influence on all these other parts of our health?

So our gut microbiome is not an organ in the conventional sense, but it's a community of trillions of bacteria, fungi, yeasts, and parasites, which live in our large intestine.

And each microbe is capable of producing hundreds of chemicals, which as I was saying, gets sent all around the body to help with our brain health, heart health and skin health.

And 70% of our immune cells are found within the lining of our gut, which is why if we eat a healthy diet, we can help to support a healthy immune system.

Oh, that's fascinating.

I mean that's fascinating to me to think that what we eat can impact all these various aspects.

Tell me a little bit more about the link between food and mood.

So how what we eat can impact our mental health.

So 90% of our serotonin known as our happy hormone, is actually produced within the gut, which is just another reason why it's so important to eat a diet rich in plant-based foods and dietary fibre to help improve our mental health.

And is it true that also the other opposite way is true, you can do things to look after your emotional health and that can give you better gut health?

Absolutely, so there's certain things you can do to help reconnect the gut and the brain, as it were, simple practises such as breathing, because breathing out helps to stimulate that rest and digest nervous system.

Another thing is meditation or mindfulness because that can make you become very present and listen and tune in to what's going on inside the body.

And one of my favourite practises is yoga because as well as including the breathing and the meditation, yoga also involves movement like stretching and compression, which is almost like a little massage for your internal organs and for your guts.

So when it comes to a healthy diet, the guidance seems to change all the time.

The ideas change all the time.

But if we're focusing on looking after our gut health, what suggestions would you have for a healthy diet?

So I suppose my top tips would be to try to eat a diverse range of plant-based foods.

That doesn't mean being 100% plant-based, but aiming for about 30 different plant-based foods per week.

The other thing is to avoid unnecessarily restricted diets.

So avoiding excluding any whole food groups unless you have a medical diagnosis to do so.

So that means not completely cutting out carbs or cutting out fat, for example.

Exactly and actually carbs are super important in our diet because they are so rich in dietary fibre.

The other thing is to try to eat the rainbow when it comes to different fruits and vegetables because they all provide us with different antioxidants and polyphenols, which our gut microbes love and reducing our intake of these ultra processed foods.

So these are foods which contain things like artificial sweeteners, unknown ingredients, and are higher in fat and sugar.

And in addition to all of that, you can experiment with things like fermented foods.

So I'm talking sauerkraut, kimchi, kombucha, kefir, because we know again, these are really beneficial for our our gut microbes.

And we're gonna be covering more of that a little bit later on as well.

So whilst it is natural then to focus on the foods we eat, when we're talking about gut health, there are other parts of our life that are important as well, aren't there?

Like hydration and sleep?

Absolutely, so I always say the most important thing is to chew your food really thoroughly because I think we forget that digestion really does start in the mouth and the more we can chew our food, the easier it is for our body to absorb the nutrients from the food that we eat.

The other thing is to try to avoid wearing high wasted tight fitted clothing because the external abdominal pressure can sometimes worsen digestion and lead to things like abdominal bloating.

Trying to stop smoking and reduce your alcohol intake is really important because smoking can decrease the diversity of the gut microbiome.

It's also important to remember to avoid taking unnecessary medications.

We all need to take medications from time to time, but especially things like the overuse of antibiotics, antibiotics as well as killing off the bad bacteria can often wipe out a lot of the good bacteria.

And the final thing is to really make sure we are drinking enough fluid every day because we've talked about the importance of upping our dietary fibre, but fibre requires fluid to work effectively in the gut.

So we wanna aim for two litres or eight glasses of water every single day.

Wow, so lots to think about, but I think for people, even if you make adjustments to just one or two of those things, then you're gonna make improvements, aren't you?

Absolutely.

Thank you so much Kaitlin, for giving us that insight into the importance of our gut health and especially how it can impact our overall health.

So I'm now with Iona Bell who's a specialist dietitian at Bupa's Cromwell Hospital.

And we're gonna be talking a little bit about gut health issues and touching upon food intolerances.

So Iona as a specialist dietitian, tell me a little bit about your role and your day job.

So I currently work as a specialist dietitian at Cromwell Hospital.

So my mornings consist of ward rounds and also developing nutritional regimes for the patients on the critical care unit.

So this is from IV nutrition to enteral feeding, which is where we insert a tube to feed directly into the gastrointestinal tract.

And my afternoons are spent in the outpatient clinics, with the other specialist dietitians.

And we see a wide variety of patients from IBS, inflammatory bowel disease, coeliac disease, diverticulitis, intolerances and oncology cases as well as many other clinical conditions.

So how might we know when something is potentially wrong with a gut?

What are the telltale signs and symptoms we should look out for?

So if you think that something might be wrong with your gut, you may notice symptoms such as constipation, diarrhoea, flatulence, bloating, abdominal pain and cramps, and a general change in bowel habit.

But it's important to remember that these symptoms can be caused from a wide variety of conditions and you may have one or two of the symptoms or you may experience most, if not all of them.

Okay and I think all those things you mentioned, they're all things that we, I guess we'll get a little bit from time to time.

So when would you recommend is the right time to seek help to go and see your GP for example?

So you should see your GP if you think that anything is wrong with your gut, especially where symptoms are having an impact on your day-to-day life.

And if you're noticing any blood in your stools, a change in stool consistency or a change in stool colour and your GP will then build to help support you and also send you for some further tests.

Okay, so I guess based on that, you might get referred for some tests and you may even get a specific diagnosis and there are many different things that people might get sent to you for, aren't there?

What sort of types of things would you see?

Yeah, so we receive referrals for a variety of reasons through self-referrals or referrals through consultants and GPs.

Some of the most common referrals that we see are those for ulcerative colitis, Crohn's disease, coeliac disease and IBS.

But we also receive referrals for general gut health and also how to manage your intolerances and allergies.

So you mentioned IBS there and I think that's probably one of the commonest conditions people think of when it comes to gut health.

But then there's also IBD which is different.

Can you explain the difference?

Yeah, so inflammatory bowel disease is used to describe two conditions, Crohn's disease and ulcerative colitis, which both cause inflammation in the gut.

Crohn's disease affects any part of the gastrointestinal tract from the mouth all the way to the anus.

Whereas ulcerative colitis only affects large intestine.

If you think that you might have inflammatory bowel disease, you might notice symptoms such as blood in your stool, bloating, lethargy, weight loss, abdominal pain, cramps and discomfort.

Generally the symptoms of IBD will last for a period of time, which is what we call a flareup before going away.

It's really important if you think that you have IBD to speak with your GP as they'll be able to help to offer you some advice as well as send you for some tests and treatment.

Irritable bowel syndrome on the other hand is a condition that affects the digestive tract but there's no inflammation of the gut.

Symptoms can be quite similar to that of IBD.

For example, you might get the bloating and the diarrhoea.

Okay, great, thanks for explaining that.

And if people do get a diagnosis of a specific condition, is this then when they're likely to be referred to somebody like yourself and you can look at diet and other potential causes of their symptoms and help them with a management plan?

Yes, we can help in a variety of ways.

For example, if someone comes to us who has IBS, we generally might ask them when their symptoms first started.

And for some this can be during a really stressful period of time in their lives, for example, in their job or it might be after a loss of a family member or close friend.

We will also take a diet history and also understand the symptoms that they're currently experiencing.

From there we can give them first sign advice, which includes stress management, exercise, dietary advice, and also symptom control.

And if felt appropriate we can give them the low FODMAP diet advice as well.

So you mentioned a low FODMAP diet.

Can you tell me a little bit more about that?

Yeah, so the term FODMAP is an acronym used to describe short chain carbohydrates that are poorly absorbed in our small intestine.

FODMAP stands for fermentable, oligosaccharide, disaccharide, monosaccharide and polyols.

And these short chain carbohydrates are poorly absorbed in everyone, but in those with IBS, will cause them symptoms.

Right?

These FODMAP are found in everyday foods.

For examples in onions and garlic, it's really important if you're going to go and do the low FODMAP map diet that you speak with your dietitian who can help advise you through the three stages.

This consists of complete elimination of these FODMAP foods from your diet before bringing them back in one by one to see which caused symptoms and which you can tolerate.

And now a hotly debated topic in our recent Bupa customer survey was food intolerance.

Over 40% of customers responded said that they wanted to know more about it, so it's really a topic of great interest.

So I wanted to ask you a bit about that.

And firstly, what's the difference between food intolerance and food allergy?

So a food allergy is a reaction that involves the immune system.

It's where the body mistakes a protein that's found in food as a threat and therefore a number of chemicals are released, which cause the symptom of the food allergy.

Almost any food can cause a food allergy, but the most common are nuts, eggs, fish, shellfish, some fruits and vegetables and milk.

A food intolerance on the other hand does not involve the immune system.

And having a food intolerance can cause a wide variety of symptoms and reactions.

But these can be very individual to you with a delayed or immediate onset.

And what are the most common things in the diet that might cause a food intolerance or a food sensitivity?

So one of the most common food intolerances that we see is a lactose intolerance.

And this is where someone might be able to tolerate a little bit of lactose in their diet or no lactose at all.

We also see a non-coeliac gluten sensitivity and this is where despite someone not being diagnosed with coeliac disease or wheat allergies still find that the gluten in food causes them some symptoms such as diarrhoea, bloating, flatulence and abdominal pain.

So would you say that more often than not it tends to be a case of food sensitivity rather than an intolerance?

Yeah, so for example, in someone who has IBS, they might find that having a tables spoon of onions does not cause them any symptoms.

But having three tables spoon of onions causes them quite a lot of gut sensitivity and then brings on those symptoms.

It's the same for example, someone with lactose sensitivity that they can tolerate a lactose containing yogurt.

Having a lactose containing cheese or milk causes them quite severe symptoms.

So what sort of symptoms might somebody get from a food intolerance or sensitivity?

'Cause they can present in all sorts of interesting ways, can't they?

Yeah.

So if you've got a food intolerance or sensitivity, the symptoms of this are very individual to you and they can present in a variety of ways.

However, some of the most common symptoms that we see is bloating, diarrhoea, flatulence and abdominal pain.

Some of the less common symptoms include heartburn, lethargy and tiredness, nausea and acid regurgitation.

So if I suspect that I have an intolerance, should I go ahead and just start cutting things out of my diet and manage that myself or do you think it's better to seek some advice from a healthcare professional?

So you should always see your GP if you think that something might be wrong with your gut and is causing you concern.

However, if you suspect that you have a food intolerance or sensitivity and you can by all means do this on your own and by doing the food elimination and reintroduction method, so this involves taking that food that might be causing you symptoms such as bloating and removing it from the diet.

And then if the symptoms go away, you can then slowly reintroduce it back into the diet and if the symptoms return then you know that this food is causing you problems.

It's important to do this if you can under the supervision of a dietitian as they can help to ensure that your diet doesn't become too restrictive and it stays nutritionally complete.

Okay, so maybe if it's just the one particular type of food, have a go yourself but if there's loads of different things you really need some help with that?

Yeah, definitely.

Yeah, okay.

And what if somebody wants to find out for sure, and a lot of my patients, they want to do a test, they wanna do a quick diagnostic test to find out if they're food intolerances, can they do that?

So unfortunately unlike allergy testing, testing for food intolerances lack some validity.

There's lots of commercially available tests that you might have seen out on the market, but these tests tend to lack quite good evidence to back their claims.

An example of these tests, one is a hair analysis test and this involves taking a strand of your hair and sending it off to the lab to test for food intolerances.

But there's no scientific basis behind this and it lacks that good evidence.

There's also IgG testing, which is where a sample of blood is sent away and it's tested for the IgG antibodies in the blood and it's thought then increasing these antibodies to certain foods shows an intolerance to that food.

However, it's been found that people who are healthy and have no symptoms at all have an increase in these antibodies as well.

And it's thought that the foods that you might commonly eat might show up as an intolerance so you might end up restricting unnecessarily.

There's also kinesiology testing, which is where muscle reactions are looked at when a food is placed near and next to the body.

However, there's no scientific basis behind this and it's thought that the muscle reaction is no better than chance.

Okay, so I guess in summary there's no simple test but if you're having symptoms, if they're persisting, particularly if you're having any symptoms you think could be IBD, it's definitely worth a trip to the GP to get some help and support.

Yeah, definitely always go to your GP if you're are struggling with anything or think that there's anything wrong.

Iona, thank you so much.

That was really interesting and really useful and really good to know that it's the support out there to help people.

Now all of this talk of food has made me think that it's time to unpack what is good and what is bad.

So I'm here in the kitchen with Kaitlin and I think it's probably fair to say that not a week goes by without a new health kick, new fad diet, new supposedly super food of which there is no such thing.

So it's really great to find out what is fact and what is fiction.

And I've got some foods here, some of which we probably tend to think of as good for us and some of us we might think of as not so good for us.

So let's have a look at them.

But before we start with that, I wanted to ask you about probiotics.

So we see lots of probiotic supplements being marketed, but also probiotic drinks in the supermarkets now like kombucha and and kefir.

So are they good for us and should we be investing in them?

So really good question.

So you can find probiotics in food that contain live beneficial bacteria, particularly fermented foods.

So things like kefir, kombucha, kimchi or sauerkraut.

We have limited evidence to show their benefit, but lack of evidence doesn't equate to lack of benefit and we have lots of ancestral evidence to show that these can be really beneficial for our health.

Those aren't to be mistaken with probiotic supplements, which you can buy in capsule form or even some probiotic drinks.

And I just want to make it clear that a normal healthy person does not need to take probiotic to improve their gut's health.

However, if you have a particular gut symptom you're trying to manage, then there might be a particular strain of probiotic bacteria which has been shown in the research to help manage that particular symptom.

Okay, good to know.

And what's the difference between a probiotic and a prebiotic?

So probiotics are the live beneficial bacteria we can take to either maintain or improve our gut health, whereas prebiotics are the food for that gut bacteria and we can get prebiotics from different high fibre foods in our diet.

For example, things like onions and garlics, apples and pears, artichokes, beans and lentils, just to name a few.

Okay, great.

Now one thing I wanted to ask you about and I'm thinking about this plate over here is what are the red flags when you're in a supermarket?

'Cause often packaging and marketing can be quite misleading and have us believe things are good for our health when actually they're may be not so great.

Absolutely.

So it can be really confusing for a consumer to know what's good for our health and what's not and you want to be careful of products that are labelled as natural or even vegan.

That doesn't necessarily mean they're healthy for us.

So for example, if you pick up a packet, it's always good to look at the ingredients list.

You want to be able to understand and read all of the ingredients in the product.

There's about a lot of ingredients on there, some things that I've never heard of before.

Absolutely, so several ingredients, some of which you don't even know what they are.

So although this may look like a healthy choice.

It does.

It may not be the most beneficial thing.

Whereas when you see other products and this is a bar which contains just five ingredients that or whole natural foods and you therefore know this is a little bit better for your health.

So I guess there's no shortcuts.

You kind of have to look at the ingredients list and then make your own decision.

Yeah, absolutely.

One thing I wanted to ask about is caffeine.

So we've got some coffee, tea and colas here.

Is caffeine really that bad for us?

So most people can consume up to 400 milligrammes of caffeine a day.

Pregnant women just 200 milligrammes or so.

How many cups is that?

So that would be about depending on the strength of the tea of coffee, roughly four cups of tea or three cups of coffee.

Okay.

And you can consume that safely without any adverse side effects.

But caffeine is a stimulant and can worsen gut symptoms in those who are sensitive and it's all to do with how caffeine is metabolised in the gut.

And for people who are sensitive impacts can include nervousness, anxiety, and insomnia as caffeine can spike that stress hormone cortisol as well as cause these gut symptoms.

Okay, any any health benefits to these?

Tea and coffee is rich in what we call polyphenols and we know that polyphenols are really good for our gut health.

Any health benefits to to these two and is one worse than the other?

So things like fizzy drinks, they do contain caffeine but they don't contain any other nutrition for our body in that sense.

Okay, so there's no real benefit to having them.

And what about artificial sweeteners?

Are they bad for our gut health?

There is evidence to show that high consumption of artificial sweeteners is detrimental to our gut health.

So it's best to try to avoid them where you can.

Okay, I've got some chillis here.

So spicy foods, some people tend to think of these as as triggers if you do have gut symptoms.

So are they good for us or not?

The active component in chilli is known as capsaicin and some people are affected by spicy foods whereas others are not.

And we tend to see those with increased gut sensitivity such as those with IBS become more sensitive to spicy foods.

Okay, and what about alcohol?

Does that have a negative impact on our gut health?

So alcohol can increase the permeability of our gut.

A term you may have heard be called leaky gut, which can increase the sensitivity of the gut lining, especially in those with IBS.

Now some people may be intolerant to certain components of alcoholic drinks such as the gluten found in beer for people with coeliac disease, whereas others may react to the histamines or the sulphates found in different alcoholic products.

Some alcoholic drinks for example, red wine do contain polyphenols, which we know can be beneficial for our gut health.

However, excess alcohol consumption isn't beneficial for our overall health.

So it's important to try and reduce our intake where we can.

Okay, now this one I'm really interested in chocolate, good or bad?

And are all chocolates equal?

So the higher the percentage of cocoa, the more polyphenols and flavonoids it contains, which again can be really beneficial for our gut microbes.

However, we want to avoid over consumption of any type of chocolate and especially the chocolates with the lower percentage of cocoa, they tend to be higher in fat and sugar, which we know isn't beneficial for our gut health.

OK and I thing with those sort of richer chocolate, you actually need a small amount to feel satisfied.

So it'll be beneficial.

Here I've got some aubergines and tomatoes, although we know fruits and vegetables generally are very good for us, these are part of the nightshade family and some people believe that the nightshade family can cause inflammation in the body.

Is there any truth in that?

So we have no evidence to show that nightshades can cause inflammation in the body.

And in fact, if we avoid all of these fruits and vegetables, we can be unnecessarily restricting the diversity of our diet, which we know is detrimental to our gut health.

When it comes to gut health, is it true that things like garlic, onions and leaks are particularly good as prebiotics?

Absolutely.

They're really rich in these prebiotic fibres as well as things like beans and lentils, artichokes.

So they should definitely form part of a balanced diet.

And what about all the diets and crazes out there?

So juice cleansers, keto, Atkins, where do they stand when it comes to gut health?

So none of these diets have any evidence to show that they can be beneficial for our gut health.

In fact, they're all very low in dietary fibre, which we know is the most important thing when it comes to looking after our gut health.

People may feel temporarily better when they have a complete overhaul of their diet, but often these diets are unsustainable and they're not providing our gut microbes with any goodness that they love.

I also wanted to mention about vegan diets because people adopt a vegan diet assuming it equals a healthy diet, but that's not necessarily the case.

When we look at the premise of a vegan diet, it's to increase your intake of plant-based foods, which are rich in dietary fibre, which can increase the diversity of the gut microbiome.

However, you don't have to go completely vegan to improve your gut health, but focusing on a more plant-based diet, including some animal sources, can still have the same beneficial effect.

Thanks so much Kaitlin.

So I guess to wrap up, for people who don't have any conditions or intolerances, diet diversity really is the way to go alongside being active, looking after our mental health and presumably the occasional treat is okay.

Absolutely.

Thank you so much Kaitlin, that was so interesting.

Kaitlin, I've read that fasting is beneficial for my gut and may ease my symptoms, is that true?

And do the times that we eat affect our gut health?

It is recommended to avoid eating two to three hours before you go to bed because our digestive system does slow down at night.

And this is especially true if you suffer from nocturnal reflux, which is reflux in the evening.

There is some evidence that giving your gut a rest, ideally 12 to 14 hours overnight can be beneficial to allow specific microbes to essentially clean up the lining of your gut, which can keep it really healthy, which is really important to support a healthy immune system.

However, there's no need to skip meals and typically an overnight fast is more than sufficient and it's actually recommended to try and eat a balanced meal every four hours during the day.

So that would include your complex carbohydrates, your protein, and your healthy fats.

Okay.

In some cases it might be recommended to eat little and often especially those who suffer from bad bloating or diarrhoea because smaller meal sizes can sometimes help to ease symptoms.

I think it's become quite popular to extend that fast.

A lot of people are aiming for around 18 hours a day, so there's no evidence that that's beneficial for gut health.

Not necessarily.

The evidence really lies more in people who are aiming to lose weight, but with anything to do with the diet, it's not a one size fits all.

Yeah.

This approach is really effective for some people but not others.

Okay, thank you.

Iona, question for you.

I regularly get heartburn after eating.

How can I make it stop?

So if you regularly get heartburn after eating, it's really important to speak to your GP and they might be able to prescribe you some medications to help with the symptoms.

There are some dietary foods that have been found to aggravate symptoms.

These are spicy foods, fatty foods, caffeinated drinks, tomato products, and also your citrus fruits and juices.

And it might be recommended to try and reduce your consumption of these or eliminate them from the diet it is also advised to try not eat two to three hours before you go to bed and also make sure you're following a healthy balanced diet.

Okey-dokey.

Kaitlin, should I avoid antibiotics?

Will it make my gut health worse?

Now look, we all become ill at times when antibiotics really are a necessity, but avoiding antibiotics unless absolutely necessary leaves the healthy gut bacteria from being wiped out and causing long-term changes to the gut microbiota.

In terms of the evidence for if we do take antibiotics, there is some evidence that actually taking probiotics can help to prevent antibiotic associated diarrhoea.

So it'd be recommended to take them for the duration of the antibiotic course and for two weeks afterwards.

Okay.

And would it be just specific patient groups that that would be recommended for or anyone who's taking antibiotic?

Anyone in particular who's taking an antibiotic could benefit from taking a probiotic.

Okay, all right, that's good to know.

Next question, what causes Crohn's disease?

That's one for you, Iona.

So the prevalence of Crohn's disease is increasing worldwide, but the exact cause of Crohn's disease still remains unknown.

There are some risk factors that have been found to maybe increase your prevalence of Crohn's disease, for example, it's more likely to be diagnosed in your adolescents and younger adults as well as your genetics can play a role.

So someone in your family is diagnosed with Crohn's disease and you also then have an increased chance of getting Crohn's disease.

There's also some other factors, for example, your environment and your ethnicity.

I would like to point out though that food and stress, although they can aggravate symptoms, these have not been found to actually be a cause of Crohn's disease.

Okay.

And Kaitlin, are there genetic links to things like IBS or is it all sort of due to the environment and therefore more controllable?

So it has been shown for IBS to run in families.

So if people haven't discussed their gut symptoms with their family, then I always encourage them to do so because they might not be the only ones suffering alone.

But relatives of an individual with IBS are two to three times more likely to have IBS.

However, studies have shown that individuals may develop IBS sporadically, meaning no one else in the family necessarily suffers from IBS.

And I guess the thing with things running in families is the the genetics that connect the family.

But often people in the same family have similar environmental risks as well, don't they?

It can be difficult to unpick what the reasons are.

Exactly.

Okay, question for you Iona.

What would you recommend to cure repeated constipation?

So if you're struggling with constipation, it is important that you speak with your GP and they might be able to prescribe you some laxatives or there might be another problem that they can help diagnose you with.

But there are some dietary changes that you can make.

One is making sure that you've got enough fibre in your diet, so you're getting the recommended 30 grammes of fibre a day.

So this is found in your fruits and vegetables and also your whole meal products.

It's also important that you're saying hydrated, having the recommended six to eight glasses of water per day and also exercising if you're able to.

And do we have a specific diagnosis of constipation?

When does it become constipation?

I mean I guess I'm asking about frequency of having your bowels moved.

So a normal frequency of bowel movement tends to be between one to three stools a day.

If you find that you're outside of your normal habit and you're not going as regularly as you maybe once were, then that's when you maybe want to start speaking to your GP.

Kaitlin, one for you.

I find that my bowel habit tends to change at different times in my menstrual cycle, is this normal?

Absolutely, so we see differing gut symptoms at different times of the menstrual cycle due to the change in hormones.

So during menstruation, AKA the period, you get an increase in this hormone like chemical called prostaglandin.

The role of prostaglandin is to get the lining of the uterus to contract, but that effect doesn't just stay in the uterus and it can also have an effect on the bowel, which causes an increase of movement of food through the digestive system, which leads to looser and more frequent poops.

Okay.

On the flip side, during the luteal phase of menstruation, we get an increase in the hormone known as progesterone and this can actually slow down the rate of motility through the digestive system leading to things like constipation.

Okay, okay that's really interesting, thank you.

And then my final question is another one for you, Iona.

What causes wind, how much is too much?

Is there a certain point in which we need to be alarmed and does it differ from person to person?

So wind is perfectly normal and it's produced as part of our digestive process when the foods that we eat are fermented in our large intestine in some conditions, for example, IBS, people might find that they produce more wind after eating certain foods than what they normally would.

In terms of wind, how much someone produces is very individual to them.

So if you find that you're producing more than normal, then it's important to go and speak to your GP just in case there's something else going on.

So I think it's kind of like with a lot of things, isn't it?

What's normal is quite a wide variety, but if there's a real significant change for what your normal is, that's when you should seek some help and advice.

Exactly.

Well that's it.

I'm afraid that's all we have time for today.
