Why Does My IBS Flare Up in the Morning?

Your IBS is worse in the morning because four separate things land inside roughly the same ninety minutes. Your colon is close to silent while you sleep and switches on the moment you wake. The strong, long contractions that you feel as urgency cluster right after waking. Your rectum registers urge and pain at lower thresholds in the morning than it does in the evening. And then breakfast, and often coffee, each add another push on top.

None of that is unique to IBS. Everybody's colon does it. What is different in IBS is that a normal amount of activity is felt much more loudly, so the ordinary morning wake-up call turns into cramps, three trips to the bathroom and a calculation about whether you can leave the house.

This guide goes through each of those four mechanisms with the studies behind them, explains why the afternoon is usually easier, and covers the part almost nobody writes about: why waking up two hours early to "empty out" can quietly make the whole thing worse.

The short answer: four things land in the same ninety minutes

Most explanations of morning IBS stop at "the gastrocolic reflex". That is one of four mechanisms, and on its own it does not explain why so many people report symptoms before they have eaten anything at all.

Here is the fuller picture, in the order it happens:

1. Overnight loading. Your colon is close to motionless for seven or eight hours while contents keep arriving from the small bowel and bacteria keep fermenting them.
2. The wake response. The moment you surface from sleep, colonic motility rises and the strong propagating contractions that produce an urge start firing.
3. Heightened sensitivity. Your rectum reports urge and pain at lower thresholds in the morning than later in the day.
4. The meal response, twice. Breakfast triggers a further increase in colonic activity, and for many people so does coffee, within minutes.

Then add whatever is happening in your head about the commute, the meeting, or the seat on the train with no toilet nearby.

Each of those has evidence behind it, and each is worth understanding separately, because they suggest different things you can actually change.

Your colon is almost silent all night, then switches on when you wake

The colon has a daily rhythm, and it is a big one. Overnight it does very little. On waking it starts working, hard.

The cleanest evidence comes from studies that threaded pressure sensors through the colon and recorded for a full 24 hours. In the first of these, 14 healthy volunteers were recorded continuously while they ate two large meals and a breakfast. Colonic motor activity was low before meals and minimal during sleep, and the motility index rose significantly after meals and at morning awakening. Almost all subjects showed isolated high-amplitude contractions that travelled long distances down the colon, and most of these occurred after morning awakening. The authors noted that these contractions were often felt as an urge to defecate, or came just before a bowel movement (Narducci 1987).

Those long-distance contractions have a name: high-amplitude propagating contractions, or HAPCs. They are the manometric version of what older textbooks called a mass movement. They are not subtle. In a separate study of 20 healthy volunteers, their average amplitude was around 110 mmHg and they lasted about 14 seconds, travelling about 1 cm per second. Their frequency peaked after meals and after awakening in the morning, and was at its minimum in the late afternoon and overnight (Bassotti 1988).

A 2023 review pulling together the manometry literature put a number on it: across studies, up to 90% of HAPCs occur during the daytime and they are relatively rare at night. Where hourly distributions were reported, the peak occurrence was detected at awakening around 7am, just after breakfast around 9am, and after lunch around 1pm (Hibberd 2023).

This shows up in population data too. When researchers asked nearly 1,900 adults in Bristol to record three consecutive bowel movements, most defecations occurred in the early morning (Heaton 1992). That was a general population sample, not an IBS sample. The morning peak is human, not a symptom.

Waking is the trigger, not the clock

This is the part that explains why weekends feel different, and it is more specific than "your body clock".

A study that combined colonic pressure recording with full sleep monitoring in 11 healthy volunteers found that propagating contractions were essentially eliminated during slow-wave sleep, rose again during REM sleep, and that transient arousal from stable sleep, with or without actually waking up, was a potent and immediate stimulus for colonic propagating contractions. The authors concluded that sleep itself, rather than lying down or the passage of hours, is the major determinant of the daily variation in colonic motility (Furukawa 1994).

Read that again: arousal is the stimulus. Not breakfast. Not standing up. The transition out of sleep.

That is why a common report in r/ibs is that alarms are worse than natural waking, and that weekends and holidays are easier. In a thread asking whether anyone else's IBS is worse in the morning, one of the most upvoted observations was that pretty much any morning that starts with an alarm is a struggle, and that things are noticeably better on days when waking happens naturally (r/ibs thread). That is lived experience rather than evidence, but it lines up neatly with what the manometry shows.

The reverse case makes the same point from the other direction. Researchers analysed wireless motility capsule data from 190 people and measured the change in colonic contraction frequency in the hour after waking. In healthy people and in people with normal-transit constipation the wake response was clear. In people with slow transit constipation it was significantly blunted at 20, 40 and 60 minutes after waking (Surjanhata 2018). The colonic wake response is a real, measurable physiological event that can be present, exaggerated or missing.

Why the same amount of stool feels more urgent at 7am

Motility is only half the story. The other half is how loudly your gut reports what is happening, and that also changes with the time of day.

In a study of 12 healthy male volunteers, a balloon was inflated in the rectum under computer control at seven standardised time points across a full day and night, and participants reported when they first felt it, when they felt an urge, and when it became painful. Sensory thresholds for urge and pain varied significantly with the time of day, with higher thresholds in the evening than in the morning (Enck 2009). A higher threshold means it takes more to register. So the same physical distension that you would barely notice at 9pm reads as urgency at 7am.

Two caveats worth stating plainly. This was a small study, only 12 people, and all of them were young healthy men rather than people with IBS. It has not, as far as we could find, been repeated in an IBS population. So it is a mechanism that fits, not a proven explanation of your mornings.

But it matters because IBS is characterised in part by heightened visceral sensitivity in the first place. If your baseline threshold is already lower than average, and the daily rhythm pushes it lower still first thing, the morning becomes the point in the 24-hour cycle where the gap between what is happening and what it feels like is widest.

There is a related finding in IBS specifically. In a study using prolonged colonic pressure recording in people with IBS, episodes of pain were significantly associated with high-amplitude propagated pressure waves, which were more frequent in the IBS group than in healthy controls (Clemens 2003). So the same contractions that cluster after waking are the ones linked to pain episodes.

Breakfast adds a second push on top of the first

The gastrocolonic response is the increase in colonic motor activity that follows eating. It is well documented, it is normal, and it is not a "reflex" in the simple sense: it involves neural and hormonal signalling and its size depends on what and how much you eat (Dorfman 2022).

What the manometry adds is that the composition of the meal changes the shape of the response. In a randomised crossover study, 18 healthy volunteers received either a predominantly fat or a predominantly carbohydrate meal while colonic pressure was recorded. Both increased activity in the first hour after eating. The carbohydrate meal produced a faster onset but a shorter-lived effect. The fat meal was slower to start but its effect persisted longer, and it was the only one that also produced more simultaneous and retrograde waves. After both meals, half the subjects showed high-amplitude propagating waves (Rao 2000).

That is a useful detail for mornings. A fried breakfast and a bowl of cereal are not the same intervention, and the difference is about timing and duration as much as about the ingredients.

The important point is that the meal response arrives on top of a wake response that has already started. In the original 24-hour study, the motility index rose both at awakening and after meals (Narducci 1987), and in the hourly distribution data the two peaks sit about two hours apart: one around 7am at waking, one around 9am after breakfast (Hibberd 2023).

This is exactly the "two poo morning" that people describe in r/ibs: wake, go, eat breakfast, go again. A thread with that title drew dozens of replies from people describing the same fixed sequence, and several said that if they skipped the second one the day felt off (r/ibs thread). The physiology says that is two distinct stimuli, not one long episode.

For how long a reaction to a particular meal takes to arrive, which is a different question from why the morning is loud, see our guide to how long after eating IBS flares up.

Coffee is a third push, and it is not really the caffeine

Coffee genuinely stimulates the colon, but not in everyone, and the caffeine is not the whole mechanism.

In an ambulatory manometry study, 12 healthy volunteers received caffeinated coffee, decaffeinated coffee, water and a 1,000 kcal meal in random order over a 10-hour period. Caffeinated coffee increased colonic pressure activity and the number of propagated contractions compared with water. Its magnitude was similar to that of a meal, about 60% stronger than water and about 23% stronger than decaffeinated coffee (Rao 1998). Decaffeinated coffee's effect was not statistically different from either water or caffeinated coffee, which tells you the study was small and the decaf sat somewhere in between.

An earlier study went looking for who responds. Of 99 healthy young volunteers surveyed, 29% said coffee gave them a desire to defecate, and that rose to 63% among the women. When 14 of them had rectosigmoid pressure measured, motility increased within four minutes of drinking coffee in the eight self-described responders, and not in the six non-responders. Both regular and decaffeinated coffee did it. Hot water did not (Brown 1990).

Four minutes. That is faster than caffeine absorption explains, and it happened with decaf, which is why the current thinking is that something other than caffeine alone is involved.

What arrived overnight is still in the queue

The fourth contributor is simple volume. Your colon was quiet for eight hours, but your small bowel was not, and neither were your gut bacteria. Whatever you ate at dinner has had the entire night to reach and ferment in the colon.

That means the morning wake response is not firing into an empty tube. It is firing into whatever accumulated overnight, and the gas produced along with it. This is the part of the puzzle that the sibling post on meal-to-symptom timing covers in detail, including why a reaction to last night's dinner can be the thing you feel this morning.

The practical upshot is that "why is my morning bad" and "what did I eat this morning" are often the wrong pairing. The morning is when yesterday shows up.

Cortisol, dread and the 6am commute

Waking is also a hormonal event. Within roughly 30 to 45 minutes of waking, cortisol rises sharply in most healthy people. This is called the cortisol awakening response, and it is now treated as a distinct phenomenon layered on top of the ordinary circadian cortisol rhythm, with its own regulation (Stalder 2025).

Is it different in IBS? The evidence is thin and mixed, and worth reporting honestly rather than confidently.

One older study measured salivary cortisol in 55 people with IBS and 28 matched controls. Compared with controls, the IBS group had significantly higher cortisol in the morning and lower in the evening, while keeping the normal circadian shape (Patacchioli 2001). That finding is often quoted online as "high morning cortisol causes morning IBS". It does not show that. It shows an association in a modest sample, measured once.

A later and more careful study sampled serum cortisol every 20 minutes through the night in 30 women with IBS and 31 healthy controls. Overall there were no significant differences in cortisol or catecholamine patterns between the IBS group and controls. There were differences between IBS subtypes: women with constipation-predominant IBS had higher noradrenaline, adrenaline and cortisol across the sleep period, and women with diarrhoea-predominant IBS had lower noradrenaline and cortisol (Burr 2009). So the simple story does not hold up, and if anything the subtype differences ran in the opposite direction to what you would guess.

Where the psychological contribution is much better established is anticipation. A very common theme across morning threads in r/ibs is that symptoms are worse on days with somewhere to be, and that the fear of not making it becomes its own trigger. In a thread about mornings from 6am to 10am being unmanageable while afternoons were fine, several replies named anticipatory anxiety directly and described the avoidance that follows: declining early meetings, not booking early flights, working from home where possible (r/ibs thread). The post that seeded this article was exactly that story, written from an airport gate by someone who had done everything they could think of to prepare for an early flight and still had symptoms hit at boarding (r/ibs thread).

IBS is formally defined as a disorder of gut-brain interaction (Lacy 2016), and the two-way traffic is the point. Morning dread is not "all in your head" and it is not imaginary: it is one input into a system that is already at its most reactive at that hour.

The morning buffer trap

Here is the part that almost no article about morning IBS mentions, and it is the one worth the most.

The standard coping strategy is to wake up earlier. An hour earlier, then ninety minutes, then two hours, so that there is time to get everything over with before you have to leave. It works, in the narrow sense. It is also the single most common thing people describe in morning threads: waking at 5am for an 8am start, at 4am for a 7am start, building the whole day backwards from an unpredictable bathroom window (r/ibs thread).

The problem is the sleep you are spending to buy it.

In a study of 24 women with IBS who kept sleep and symptom diaries for a full menstrual cycle and wore actigraphs for a week, poorer self-reported sleep quality significantly predicted higher abdominal pain, anxiety and fatigue the following day. Objectively measured sleep efficiency predicted worse next-day anxiety and fatigue. When the analysis was run in reverse, symptoms did not generally predict the following night's sleep (Buchanan 2014). The arrow pointed mostly one way: sleep to symptoms.

A systematic review of the sleep and IBS literature found that sleep disturbances are well documented in IBS and that several studies link poorer subjective sleep quality to more severe and more frequent gut symptoms, while noting that studies using objective measures such as polysomnography and actigraphy have been less consistent (Tu 2017).

So the loop looks like this. Bad mornings cause you to wake earlier. Waking earlier shortens and fragments your sleep. Poorer sleep predicts more pain and anxiety the next day. More pain and anxiety makes the morning worse, so you set the alarm earlier still.

We have written separately about why IBS comes and goes from day to day, which covers the sleep-to-next-day link in the context of general symptom variability.

Why some people with IBS-C say mornings are their best window

If you have constipation-predominant IBS, the whole framing above may feel inverted. Many people with IBS-C report the opposite pattern: they feel fine on waking, and the bloating builds through the day until the evening is the worst part. That came through clearly in morning threads, where people with IBS-C described waking comfortable and steadily inflating from the first meal onwards (r/ibs thread).

The same physiology explains both. The wake response and the meal response are the two biggest windows of colonic propulsion in the day. If your problem is too much propulsion and too much sensitivity, those windows are when you suffer. If your problem is too little propulsion, those same windows are your best chance of anything happening at all, and the discomfort accumulates in the long gap between them.

The evidence for the difference is direct. In IBS with constipation, the frequency of high-amplitude propagating contractions over 24 hours is reduced compared with healthy people. In IBS with diarrhoea, HAPC frequency during the active daytime period is higher than in controls (Hibberd 2023). And in slow transit constipation specifically, the wake response itself is measurably blunted (Surjanhata 2018).

If you are not sure which pattern you have, or whether it has shifted, our guide to the difference between IBS-D and IBS-C explains how subtype is actually defined and why it is less stable over time than most people assume.

A timeline of a typical IBS morning

This is a composite, not a prediction, and clock times will differ for everyone. It is meant to show which mechanism is doing what, so you can work out which part of your own morning you might be able to move.

Shift work, weekends, and the morning that moves

If the morning peak is driven by waking rather than by the clock, then changing when you wake should change when the peak lands. That is broadly what the shift work evidence suggests, and it comes with a warning.

In a UK Biobank cohort of 239,760 people in employment, compared with day workers, those doing rare or some night shifts had a modestly higher risk of developing IBS (hazard ratio 1.10, 95% CI 1.01 to 1.20) and those doing usual or permanent night shifts higher still (hazard ratio 1.21, 95% CI 1.05 to 1.41). Longer duration and higher frequency of night shifts both carried higher risk (Yao 2025). These are observational associations with modest effect sizes, so they show a link rather than proof that shift work causes IBS.

A cross-sectional study of 392 night shift workers in Australia and the UK found that 21.3% met Rome IV criteria for IBS and 30.4% for functional dyspepsia. Nearly 60% said night shifts negatively affected their gut symptoms, and 16.3% had considered changing jobs because of them (Pennaneach 2026). Again, cross-sectional: it cannot separate cause from effect.

Reviews of circadian physiology in the gut give the mechanism a plausible shape. Peripheral clocks exist in the gut epithelium and in the enteric nervous system, they can be reset by light, sleep timing and meal timing, and disruption of those rhythms has been linked to altered motility, permeability and microbial composition (Duboc 2020, Bishehsari 2025).

Closer to everyday life, researchers have examined chronotype and social jetlag, the gap between your natural weekend sleep timing and your enforced weekday timing, in 62 women with IBS and 58 healthy women who kept 28-day diaries. Later chronotype predicted poorer weekday sleep quality and a sense that sleep need was not met (Yang 2021). That study looked at sleep outcomes rather than at gut symptoms directly, so it is a link in a chain rather than the whole chain. But combined with the next-day sleep-to-pain finding, it offers a reasonable account of why a late chronotype forced into a 6am start might have particularly rough mornings.

What actually helps, ranked honestly by evidence

There is no trial of "interventions for morning IBS". Nobody has run one. What follows is what the general IBS evidence supports, ordered by how well it is established, with the morning-specific reasoning attached. None of it is a recommendation to start, stop or change any medication or supplement: those conversations belong with your GP or gastroenterologist.

Best established:

• Psychological therapies. A network meta-analysis of 41 randomised trials and 4,072 participants found that cognitive behavioural therapy, both face-to-face and self-administered or minimal-contact, was among the interventions with the clearest efficacy for IBS symptoms (Black 2020). For morning symptoms specifically, the relevant target is often the anticipation and the avoidance rather than the gut itself. Both the ACG and BSG guidelines include gut-directed psychological therapy among recommended options (Lacy 2021, Vasant 2021).
• Physical activity. In a randomised trial of 102 people with IBS, those instructed by a physiotherapist to increase physical activity had a significantly greater improvement in IBS severity scores than controls, and significantly fewer of them got worse over the study (Johannesson 2011). Worth noting: that was about activity in general, not a morning routine.

Plausible and worth discussing, but not settled:

• Protecting sleep rather than shortening it. This follows from the next-day findings (Buchanan 2014) rather than from any trial that tested it as a treatment for morning symptoms. No study has shown that extending sleep improves morning IBS. It is a reasonable hypothesis with a cost of essentially zero.
• Consistent wake times. If arousal is the stimulus (Furukawa 1994) and circadian disruption is associated with worse gut symptoms (Bishehsari 2025), a stable wake time is a plausible way to make the morning peak predictable even if it does not make it smaller. Predictable is worth a lot when you are planning a commute.
• Moving the meal, rather than removing it. The meal response is real and its shape depends on composition (Rao 2000). Shifting breakfast to after you arrive somewhere, or changing what it consists of, changes when the second peak lands. Several people in the morning threads described doing exactly this. It is a scheduling change, not a treatment, and if it turns into regularly skipping meals it is worth talking to a dietitian rather than letting it drift.

Interesting but genuinely limited:

• Melatonin. In a two-week randomised, double-blind, placebo-controlled trial of 40 people with IBS who also had sleep disturbance, melatonin at bedtime significantly reduced mean abdominal pain scores and raised rectal pain thresholds compared with placebo. Notably, it did not improve bloating, stool type, stool frequency, anxiety or depression scores, and polysomnography showed no change in sleep parameters (Song 2005). Forty people, two weeks, one outcome improved. That is a signal, not a solution, and anything you take is a conversation with your doctor rather than something to trial off your own back.

Deliberately not on this list: any suggestion about a specific dose of anything, and any elimination diet framed as a permanent fix. If a low FODMAP diet is on the table it should be a short, structured process with a planned reintroduction phase, ideally with a dietitian, not a permanent restriction.

A two-week morning experiment you can actually run

Most trigger hunting in IBS is organised around foods. For morning symptoms that is often the wrong axis, because the biggest variable is not what you ate, it is when you woke and what happened in the first hour. Here is a way to test that instead.

Log only six things, every morning, for two weeks:

1. Time you actually woke, and whether it was an alarm or natural.
2. Approximate hours slept and a one-to-five rating of how the sleep felt.
3. Time of your first bowel movement, and its Bristol type.
4. Any further bowel movements before midday, with times.
5. Time of first food and first coffee, and what they were.
6. Worst pain or urgency score before midday, zero to ten, and whether you had somewhere to be.

Then, at the end of two weeks, ask four questions:

• Is the first event tied to waking time or to clock time? Sort your rows by wake time and see whether the gap between waking and the first bowel movement is roughly constant. If it is, your morning moves with you and a later start genuinely buys you a later peak rather than a better one.
• Do alarm mornings differ from natural mornings? You will probably have a handful of each. Compare the worst-score column.
• Does the second event follow breakfast or follow the first event? If the interval from breakfast is more consistent than the interval from the first bowel movement, that is your meal response, and moving breakfast will move it.
• Do "somewhere to be" days stand out after you control for wake time? This is the anticipation signal, and it is the one most worth taking to a clinician, because it points towards a treatment with good trial evidence rather than towards another food to cut.

If you would rather not do this on paper, an app that timestamps entries as you make them does the same job with less friction. Clairop lets you log by speaking, which matters at 6am, and its insights screen looks at delay windows between an input and a symptom rather than just listing what you ate. You can read more about how it works.

When morning symptoms are probably not IBS

Morning urgency is a normal IBS pattern. Some morning presentations are not, and they have specific alternative explanations that are worth knowing about because they change what gets tested.

Diarrhoea that wakes you from sleep. This is the big one. British Society of Gastroenterology guidance on chronic diarrhoea treats nocturnal symptoms as an atypical feature that points away from a straightforward functional diagnosis and towards investigation (Arasaradnam 2018), and the BSG IBS guideline takes the same line (Vasant 2021). The physiological reason is exactly what this article has been describing: propagating contractions are largely eliminated in deep sleep (Furukawa 1994). Something that overrides that deserves a look. If diarrhoea is waking you at night, see a doctor promptly.

Very early urgent morning diarrhoea, especially after gallbladder removal or an infection. Bile acid diarrhoea is a common and frequently missed alternative. A meta-analysis of studies using SeHCAT testing found that around a quarter to a third of people diagnosed with IBS-D had evidence of bile acid malabsorption, depending on the threshold used (Slattery 2015). It is testable and it is treatable, which is why it is worth asking about rather than assuming.

Morning symptoms plus red flags. Blood in the stool, unexplained weight loss, fever, anaemia, a new change in bowel habit after the age of 50, or a family history of bowel cancer or inflammatory bowel disease are all reasons to be assessed rather than managed as IBS. See a doctor promptly if any of those apply.

Morning nausea and vomiting. Nausea is common in IBS but is not part of the diagnostic criteria (Lacy 2016), and persistent morning nausea with vomiting, early fullness or weight loss has other explanations that deserve their own assessment.

If you are weighing up whether this is a GP conversation or a specialist one, we covered that decision in should I see a gastroenterologist for IBS.

Myths about morning IBS

"It is just the gastrocolic reflex." The meal response is one of four contributors and it cannot explain symptoms that arrive before you have eaten. The wake response is a separate, documented event (Narducci 1987, Furukawa 1994).

"High morning cortisol is causing it." This is stated confidently across the internet on the strength of one modest study (Patacchioli 2001). A study that sampled cortisol every 20 minutes overnight found no overall difference between women with IBS and controls, and the subtype differences it did find ran in unexpected directions (Burr 2009). The cortisol awakening response is real (Stalder 2025); the claim that it explains your mornings is not established.

"Going three times in the morning means something is seriously wrong." Not on its own. Strong propagating contractions cluster after waking and after meals, so several can arrive close together in the same window (Bassotti 1988). It is worth reporting if it is new, if there is blood, or if it wakes you at night, but frequency in the morning window by itself is a pattern, not a finding.

"Cutting out coffee will fix it." It might reduce one of three or four pushes, and only if you are a responder. In the study that looked for responders, fewer than two thirds of those who felt coffee affected them showed a measurable rectosigmoid response, and decaffeinated coffee produced the same effect in those who did (Brown 1990).

"Waking up earlier is the answer." It is the most common coping strategy and it comes with a documented cost, because poorer sleep predicts more abdominal pain, anxiety and fatigue the next day (Buchanan 2014).

"Morning symptoms mean your diet was wrong yesterday." Sometimes. But the morning peak happens on days you ate nothing unusual, because the wake response happens every day (Hibberd 2023). If you blame a food every time you have a bad morning, you will end up with a very short list of foods and the same mornings.

If you have Crohn's disease or ulcerative colitis

The circadian physiology described here applies to everyone's colon, so morning urgency is a common experience in inflammatory bowel disease too. The interpretation is different in one important way.

In IBS, morning urgency without red flags is a pattern rather than a warning. In IBD, changes in frequency, urgency or bleeding are how a flare announces itself, and they need to be measured against your own baseline rather than explained away as "just my mornings". Waking at night to open your bowels is a particularly important signal in IBD and should prompt contact with your team.

Circadian disruption has been studied in ulcerative colitis specifically, with reviews describing links between sleep disruption, colonic permeability and inflammatory markers (Hibberd 2023, Bishehsari 2025). That is mechanism-level work, not a reason to change anything you are doing.

If you have IBD and you are trying to work out whether a run of bad mornings is a flare, our guides on how to tell if you are in a Crohn's flare and how to know if your ulcerative colitis is flaring cover how to tell, and what tests separate symptoms from inflammation.

When to see a doctor

Book an appointment, and say clearly that symptoms are worst in the morning, if:

• Diarrhoea wakes you from sleep. See a doctor promptly.
• You see blood in the stool, at any time of day. See a doctor promptly.
• You are losing weight without trying, or you have fever, night sweats or anaemia. See a doctor promptly.
• Your bowel habit has newly changed and you are over 50, or you have a family history of bowel cancer or inflammatory bowel disease. See a doctor promptly.
• Mornings are costing you sleep, work or your social life, even without any of the above.
• You have had your gallbladder removed, or your symptoms started after a gut infection, and mornings are urgent and watery. Ask specifically about bile acid diarrhoea.
• Symptoms are the same every morning regardless of what you eat, and dietary changes have made no difference.

Two things make that appointment more productive. Bring the timings rather than the adjectives: wake times, first bowel movement times, number of bowel movements before midday, and the worst score each morning. And say out loud how much sleep you are giving up to manage it, because that number often lands harder than a symptom description and it points towards treatments with real trial evidence behind them. Our guide to preparing for a GI appointment covers how to fit that onto one page.
