- Treated online: Yes, usually. IBS is diagnosed from the pattern by video, the excluding tests arranged, and antispasmodics, loperamide, a suitable laxative or a low-dose gut-brain neuromodulator prescribed around the main symptom; bleeding, weight loss, night symptoms or onset after 50 are investigated in person first.
- What it is: a disorder of gut-brain communication with an oversensitive, over-reactive bowel, affecting about 1 in 10 adults; IBS is often lifelong, fluctuates with stress, diet, sleep and hormones, and does not damage the bowel or shorten life.
- Diagnosis: abdominal pain on at least 1 day a week for 3 months, linked to bowel movements or a change in their frequency or form, with normal coeliac bloods, inflammatory markers and, where indicated, a normal stool calprotectin; no scan or scope shows IBS.
- What works: soluble fibre such as oats and psyllium, regular meals, a dietitian-led low-FODMAP trial, peppermint oil, antispasmodics, loperamide or laxatives matched to the pattern, and gut-directed hypnotherapy or CBT, which help about 7 in 10 people.
- Not IBS: rectal bleeding, unintended weight loss, diarrhoea that wakes you at night, fever, anaemia, a lump in the abdomen or a first onset after 50 are not IBS features and mean investigation, not an online prescription.
- Emergency: call 112 for severe, sudden, unrelenting abdominal pain, a rigid belly, or vomiting with a swollen abdomen and no wind, which are not IBS.
IBS does not cause bleeding from the bowel, unexplained weight loss, symptoms that wake you from sleep, or a first onset after age 50. Any of these means it is not simply IBS and needs in-person investigation, not an online prescription. If you are passing blood, losing weight without trying, feel a lump in your abdomen, or are anaemic, arrange urgent assessment. If you have severe, sudden, unrelenting abdominal pain, call 112.
Can an online doctor treat IBS?
Often, yes. Irritable bowel syndrome is diagnosed from a typical symptom pattern once alarm features and mimicking conditions are excluded, and much of its management (dietary change, antispasmodics, fibre adjustment, a dietitian-led low-FODMAP trial) can be organised by video.[1] Diagnostic uncertainty, any red flag, or symptoms that started after age 50 need in-person tests before an IBS label is applied.
If IBS has already been diagnosed, you can also start with an Express Assessment for IBS: a short online questionnaire that a licensed doctor reviews. If the doctor needs to speak to you, the video call is included.
What an online doctor will not do is stamp "IBS" on unexplained gut symptoms to make them go away. The value of the consultation is the opposite: making sure the label is earned before you spend months managing the wrong thing.

How an online consultation helps with IBS
- A positive diagnosis: the doctor works through the recognised IBS criteria and the exclusion tests (coeliac bloods, inflammatory markers, faecal calprotectin where indicated), so the diagnosis rests on evidence rather than on nothing else fitting.[1]
- Symptom-led treatment: IBS with constipation, IBS with diarrhoea and pain-predominant IBS are managed differently. The plan is built around the symptom that actually bothers you, not a generic script.
- The low-FODMAP pathway, done properly: if diet is the lever, the doctor explains the low-FODMAP approach and refers you to a dietitian to run it, because the elimination-and-reintroduction structure matters and self-directed restriction long-term does more harm than good.[2]
- Honest referral when the story does not fit: if a red flag appears or first-line treatment fails, the doctor arranges the right tests or specialist referral instead of cycling you through another antispasmodic.
What the doctor checks in an online IBS consultation
IBS is a clinical diagnosis built on a structured history, which is exactly why it suits a video assessment. In an IBS consultation the doctor will typically establish:
- The core pattern: recurrent abdominal pain related to defecation, a change in how often you go, or a change in stool form, and whether pain eases or worsens after you open your bowels.[1][5]
- Your predominant subtype: constipation-predominant, diarrhoea-predominant, or mixed, because it steers the whole plan.
- Bloating, urgency and mucus: the everyday features that are typical of IBS and reassuring when the rest of the picture fits.
- Red flags, asked directly: blood in the stool, unintended weight loss, diarrhoea that wakes you at night, a first onset after 50, iron-deficiency anaemia, and a family history of bowel or ovarian cancer. Any of these takes you off the IBS pathway and onto an investigation pathway.[3]
- Exclusion tests already done or still needed: coeliac serology, a full blood count and inflammatory markers, and faecal calprotectin to help separate IBS from inflammatory bowel disease.[1]
- Triggers and timing: specific foods, caffeine and alcohol, stress and sleep, the menstrual cycle, and whether symptoms began after a gut infection (post-infectious IBS).
- What you have already tried: fibre, peppermint oil, antispasmodics, probiotics, exclusion diets, and what each did.
What is IBS, and why is it a diagnosis of exclusion?
Irritable bowel syndrome is a disorder of how the gut and brain communicate: the bowel is structurally normal, but it is oversensitive and its muscle activity is poorly coordinated, which produces pain, bloating and altered bowel habit.[2] It is common, often lifelong, and genuinely disruptive, but it does not damage the bowel or shorten life.
Positive criteria, then exclusion
Modern practice makes a positive diagnosis when the typical pattern is present (abdominal pain linked to bowel habit, with bloating and change in stool form) and a short set of tests has excluded the conditions that mimic IBS: coeliac disease, inflammatory bowel disease and, in the right person, other causes.[1] Calling IBS a "diagnosis of exclusion" is shorthand for that safety step. It is not a reason to skip the criteria, and it is not a dustbin label for anything unexplained.
What IBS is not
IBS never explains rectal bleeding, progressive weight loss, or symptoms that reliably wake you from sleep. If those are present, the honest answer is that this is not IBS until proven otherwise, and the priority becomes investigation rather than symptom control.[3]
What triggers IBS symptoms?
Flares are usually a combination rather than a single villain. Common triggers include certain fermentable carbohydrates (the FODMAPs), large or fatty meals, caffeine and alcohol, and periods of stress or broken sleep, which turn up the gut-brain volume without causing the condition.[2] Some people develop IBS after a bout of gastroenteritis, when the gut stays hypersensitive long after the infection clears. Identifying your own pattern, ideally with a short symptom-and-food diary, is more useful than blanket food fear.
Is my IBS suitable for online care?
Usually yes, and the exceptions follow clear rules. This is the decision framework the doctors use, aligned with the cited guidance.

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Typical IBS pattern, no red flags, under 50 | Positive diagnosis, exclusion bloods, first-line diet and symptom-targeted medicine[1] | Usually yes | No response after adequate trials, or diagnosis in doubt |
| Constipation-predominant IBS | Soluble fibre, a suitable laxative if needed (not lactulose), antispasmodic for pain | Usually yes | Refractory constipation, or a new change in an older adult |
| Diarrhoea-predominant IBS | Loperamide titrated to symptoms, dietary review, dietitian-led low-FODMAP trial | Usually yes | Nocturnal diarrhoea, weight loss or blood, which are not IBS |
| Ongoing symptoms despite first-line treatment | Low-dose gut-brain neuromodulator (e.g. a tricyclic) trial with review | Often yes | Poor response, or a need for psychological-therapy referral |
| Any red flag: bleeding, weight loss, nocturnal symptoms, onset over 50, anaemia | Investigation first: bloods and appropriate referral[3] | Assessment and referral only | Always: other diagnoses must be excluded before labelling IBS |

What you can do yourself
Start with the adjustable basics: regular meals eaten unhurried, enough fluid, and a look at caffeine, alcohol and very fatty or spicy foods. For bloating and irregularity, soluble fibre such as oats or ispaghula tends to suit IBS better than coarse insoluble bran, which can worsen it. Peppermint oil capsules help some people with cramp and are available without prescription. Physical activity and attention to sleep and stress genuinely move the needle, because IBS runs along the gut-brain axis rather than in the bowel alone.[2] A two-week to four-week symptom-and-food diary is the most useful self-help tool there is.
The low-FODMAP diet, and why a dietitian matters
A low-FODMAP diet reduces specific fermentable carbohydrates and has good evidence in IBS, but it is a structured clinical intervention, not a permanent way of eating.[2] Done properly it has three phases: strict elimination for a few weeks, then systematic reintroduction to find your personal triggers, then a relaxed long-term diet as broad as your symptoms allow. Run open-endedly and alone, it narrows the diet, risks nutritional gaps and changes the gut flora for no lasting benefit. For that reason the doctor refers you to a trained dietitian to supervise it rather than handing you a list to follow indefinitely.
Prescription treatment, with honest limits
A prescription is never issued without a consultation. After assessment the doctor matches medicine to your dominant symptom: antispasmodics such as mebeverine or hyoscine, or peppermint oil, for cramping pain; loperamide for diarrhoea; and a suitable laxative (avoiding lactulose, which can worsen bloating) for constipation.[1] Be clear-eyed about what these do: antispasmodics ease spasm and pain in the moment, and their evidence is modest, so they are symptom tools rather than a cure.[4] Where pain and disturbed bowel habit persist despite first-line measures, a low-dose tricyclic such as amitriptyline can be trialled as a gut-brain neuromodulator, used at doses well below those for depression and reviewed for benefit and side effects.[1][4] None of this is a lifelong prescription by default; IBS treatment is reviewed and adjusted, not simply repeated.
When it might be something else
Part of the consultation is telling IBS apart from its look-alikes, because several conditions borrow its symptoms. Cramping lower-abdominal pain with a change in habit overlaps with ordinary abdominal pain from other causes. Loose stools with weight loss, blood or night-time symptoms point away from IBS and towards inflammatory bowel disease, which is why the doctor may check faecal calprotectin. Coeliac disease can present with IBS-type symptoms and is excluded with a simple blood test before you cut gluten. Persistent diarrhoea or stubborn constipation that does not fit the IBS pattern deserves its own work-up. And in anyone over 50 with new bowel symptoms, colorectal causes are excluded first, not assumed away.[3]
When IBS is treated online, and when you need in-person care
Treated online: people with a typical IBS pattern and no alarm features; diagnosis and first-line management, including dietary advice and a referral into a dietitian-led low-FODMAP programme; symptom-targeted medicines with review; and gut-brain neuromodulator trials for persistent symptoms. IBS is one of several stomach and digestive problems the doctors assess online.
In-person care: anyone with a red flag (rectal bleeding, unintended weight loss, nocturnal diarrhoea, a first onset after 50, iron-deficiency anaemia, or a concerning family history) is directed to investigation rather than IBS treatment, in line with referral guidance;[3] symptoms that fail adequate first-line and second-line treatment warrant gastroenterology assessment; and abnormal exclusion tests (raised calprotectin, positive coeliac serology) change the diagnosis and the pathway. In those cases the consultation buys you the right next step, with a full refund if your doctor decides you need to be seen in person.
When to get in-person care
Call 112 or go to emergency care immediately if you have severe, sudden, constant abdominal pain, a rigid or very tender belly, vomiting with no bowel movement or wind, or you feel faint alongside significant bleeding. Arrange urgent in-person assessment, within days not weeks, for blood in your stool, unintended weight loss, a new change in bowel habit after age 50, diarrhoea that wakes you at night, or symptoms of anaemia such as unusual tiredness and breathlessness. These are not features of IBS and need investigation.
Managing IBS at home: what helps and what does not
Home management is central to IBS: regular meals eaten unhurried, steady hydration, adjusting fibre to your pattern, watching personal triggers honestly rather than banning foods at random, managing stress, and peppermint oil capsules, which have fair evidence for cramping.
What home care cannot do: it cannot make the diagnosis, and IBS is a diagnosis that must exclude other things first. Blood in the stool, unexplained weight loss, symptoms that wake you at night, a family history of bowel disease, or a distinct change in pattern after 50 are not IBS until a doctor has said so. Structured elimination approaches also work far better guided than guessed.
The strongest at-home treatment is still a doctor. A video consultation brings one to your sofa: an honest assessment, and a prescription to a local pharmacy when treatment is right. You can see a doctor over video, usually within 15 minutes. Book a video consultation: the exact price is shown before you pay.

Frequently asked questions about IBS
What is irritable bowel syndrome, and what causes it?
Irritable bowel syndrome is a long-term disorder of how the gut and brain communicate, in which the bowel is oversensitive and contracts abnormally without any inflammation or damage. It is caused by a mix of a sensitised gut nervous system, altered gut bacteria, a previous bout of gastroenteritis (post-infectious IBS), stress and anxiety, food sensitivities, hormonal shifts and a family tendency; it is not caused by anything you did and it is not imagined.
What are the symptoms of IBS?
IBS causes cramping or aching abdominal pain that changes with opening the bowels, bloating that builds through the day, wind, a bowel habit that swings between constipation and diarrhoea or settles into one, mucus in the stool, urgency, and a feeling of incomplete emptying, often with tiredness, nausea or bladder symptoms. Symptoms fluctuate over months and years and flare with stress, poor sleep, certain foods and periods.
Can an online doctor prescribe IBS treatment in Europe?
Yes, after a video consultation. The doctor can prescribe antispasmodics for cramps, loperamide for diarrhoea-predominant IBS, a suitable laxative for constipation-predominant IBS, and where appropriate a low-dose gut-brain neuromodulator for persistent pain, with the prescription sent to a pharmacy near you and a dietitian referral alongside. A prescription is never issued without a consultation.
Can IBS be diagnosed without tests?
Not entirely. IBS is a positive diagnosis based on a typical pattern, but a short set of tests, coeliac bloods, a blood count, inflammatory markers and, where diarrhoea dominates, a stool calprotectin, is used to exclude conditions that mimic it, such as coeliac disease and inflammatory bowel disease. The doctor arranges the tests near you and confirms the IBS diagnosis once they are back normal.
Is the low-FODMAP diet something I should just start myself?
Better not to run it alone long-term. Low-FODMAP has three phases (elimination for 4 to 6 weeks, structured reintroduction, and a relaxed long-term diet), and unsupervised restriction risks nutritional gaps and a shrinking diet for no lasting gain. It helps about half to three-quarters of people with IBS when run properly, so the doctor refers you to a dietitian to do it well.
Do antispasmodics cure IBS?
No. Antispasmodics such as mebeverine or hyoscine ease cramping pain and muscle spasm in the moment, with modest evidence, so they are symptom tools rather than a cure, and peppermint oil capsules do a similar job. IBS management combines diet, targeted medicines for the dominant symptom and gut-brain approaches such as hypnotherapy or CBT, reviewed and adjusted over time.
When are my symptoms not IBS?
Bleeding from the bowel, unexplained weight loss, diarrhoea that wakes you at night, fever, anaemia, a lump in the abdomen, persistent vomiting and a first onset after age 50 are not features of IBS. Any of these needs in-person investigation to exclude inflammatory bowel disease, coeliac disease, infection or bowel cancer, and the doctor arranges it rather than labelling the symptoms IBS.
How long does IBS last?
IBS is usually a long-term condition that comes and goes over years, with flares lasting days to weeks and quieter stretches between; about a third of people find it fades substantially over a decade, and post-infectious IBS often settles within a year or two. It does not progress into anything else, and most people reach good control once the pattern, triggers and the right combination of treatments are found.
What can I do at home during an IBS flare?
During an IBS flare, eat small regular meals of plain food, cut alcohol, caffeine, fizzy drinks, fatty food and sweeteners, use a warm pack on the belly, walk daily, try peppermint tea or capsules, take the antispasmodic or loperamide or laxative agreed for your pattern, protect sleep, and use breathing or relaxation exercises, because the gut-brain link runs both ways. Keep a diary of food, stress and symptoms.
How can I prevent IBS flares?
Prevent IBS flares by eating regular unhurried meals, keeping soluble fibre steady and insoluble bran low, limiting the triggers a diary identifies, drinking enough, exercising most days, managing stress with a proven approach such as CBT or gut-directed hypnotherapy, protecting sleep, and continuing a maintenance pattern of the medicines that help rather than stopping them at the first good week.
Does stress cause IBS?
Stress does not cause IBS on its own, but it is one of the strongest triggers of flares, because the gut and brain share signalling and a sensitised gut reacts to stress hormones with cramps and changed motility. That is why psychological treatments such as cognitive behavioural therapy and gut-directed hypnotherapy improve IBS symptoms in trials, as effectively as many medicines, without implying the problem is in your head.
Is IBS different in pregnancy or in older people?
In pregnancy, IBS often changes, with constipation commoner as the bowel slows; fibre, fluids and pregnancy-safe laxatives are used, and antispasmodics are reviewed with the doctor. In older people, new IBS-type symptoms after 50 are investigated before the label is applied, because bowel cancer, diverticular disease and microscopic colitis are commoner, and medicines are the first suspects for a changed bowel habit.
