- Treated online: Yes, usually. Video assessment, with a prescription when appropriate.
- IBS is diagnosed by pattern once other conditions are excluded; management combines diet, symptom-targeted medicines and, where it helps, a dietitian-led low-FODMAP plan.
- IBS is a disorder of gut-brain communication; it is often lifelong but does not damage the bowel or shorten life.
- Rectal bleeding, unintended weight loss, night-time diarrhoea or a first onset after 50 are not IBS features: investigate.
- If you have severe, sudden, unrelenting abdominal pain, call 112.
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.
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 our 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 |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

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 in many countries. 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 we treat IBS online, and when we refer you
We treat 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 our doctors assess online.
We refer or redirect you: 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 we cannot help online.
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, usually within about 15 minutes: an honest assessment, and a prescription to a local pharmacy when treatment is right. Book a video consultation: the exact price is shown before you pay.

Frequently asked questions about IBS
Can an online doctor prescribe IBS treatment in the EU?
Yes, after a video consultation. The doctor can prescribe antispasmodics, loperamide or a suitable laxative, and where appropriate a low-dose gut-brain neuromodulator. A prescription is never issued without a consultation, and prescribing rules vary by country; your doctor confirms what applies to you.
How much does an IBS consultation cost?
The exact price of a video consultation is shown before payment, and there is no subscription. If the doctor can’t treat you online, you get a full refund and clear directions to the right care.
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, inflammatory markers and, where indicated, faecal calprotectin) is used to exclude conditions that mimic it. The doctor directs the tests you need locally before confirming the diagnosis.
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, reintroduction and a relaxed long-term diet), and unsupervised restriction risks nutritional gaps for no lasting gain. The doctor refers you to a dietitian to run it properly.
Do antispasmodics cure IBS?
No. Antispasmodics such as mebeverine ease cramping pain and muscle spasm in the moment, with modest evidence, so they are symptom tools rather than a cure. IBS management combines diet, targeted medicines and gut-brain approaches, reviewed and adjusted over time.
When are my symptoms not IBS?
Bleeding from the bowel, unexplained weight loss, diarrhoea that wakes you at night, and a first onset after age 50 are not features of IBS. Any of these needs in-person investigation to exclude other diagnoses, and the doctor will arrange that rather than treat it as IBS.
How quickly can I speak to a doctor?
Appointments are available daily from 7am to 11pm, often within about 15 minutes. You choose a slot that suits you, and the doctor reviews your symptoms and any previous tests during the call.
