Private IBS treatment in the UK, NICE-guided, done properly.
Indicative pricing
What private IBS treatment costs in the UK.
Indicative ranges across UK private providers.
In short
A gastro consult plus a first FODMAP dietician session: around £400–£650, typically within two weeks.
| Service | Indicative range | Typical duration | Turnaround |
|---|---|---|---|
| Private gastroenterology consultation (initial) | £250–£400 | 45 min | Report within 3–5 days |
| Faecal calprotectin (IBS vs IBD) | £70–£120 | Home kit | 3–5 days |
| Coeliac + IBS bloods panel | £120–£220 | 15 min | 2–3 days |
| BDA-registered FODMAP dietician (per session) | £120–£250 | 45–60 min | Same visit |
| Gut-directed hypnotherapy (per session) | £70–£150 | 60 min | 12-session Manchester protocol |
| CBT for IBS (per session) | £80–£150 | 50 min | 8–12 sessions |
| SeHCAT scan (bile acid diarrhoea) | £450–£800 | 2 visits, 7 days apart | Report within 1 week |
Prices vary by clinician, by whether investigations are needed to exclude coeliac or IBD, and by which combination of dietician, hypnotherapy and CBT you end up using.
The problem
IBS is over-diagnosed, under-treated, and rarely joined up.
Most patients get one drug, no dietician, and no psychology - or a permanent low-FODMAP diet without reintroduction. NICE CG61 asks for stepped care across all three.
-
Not sure it is even IBS?
Coeliac, IBD, bile acid diarrhoea and thyroid disease can look identical. Bloods and faecal calprotectin come first - before any label.
-
Tried a low-FODMAP alone?
The elimination phase is the easy half. Without dietician-led reintroduction you end up on a needlessly restrictive diet that harms your microbiome.
-
Medication only, no results?
For refractory IBS the game-changer is often psychology - gut-directed hypnotherapy or CBT - not the next drug on the list.
When it helps
The IBS patterns we treat - matched to Rome IV.
The subtypes and situations we see most, plus the one red-flag category that means investigation before any IBS label.
-
IBS-D (diarrhoea-predominant)
Loose or frequent stools most days, urgency, cramping - treatment focuses on loperamide, antispasmodics, low-FODMAP and low-dose TCA.
-
IBS-C (constipation-predominant)
Infrequent, hard or incomplete stools with bloating - soluble fibre, macrogols, linaclotide or prucalopride when refractory.
-
IBS-M (mixed pattern)
Alternating diarrhoea and constipation - the trickiest subtype, best managed by dietician plus antispasmodic, with psychology often the game-changer.
-
IBS-U (unspecified)
Symptoms fit Rome IV IBS but do not sit in D, C or M - treated symptomatically while pattern declares itself.
-
Bloating and pain dominant
Peppermint oil, mebeverine or alverine first, plus dietary triggers reviewed by a dietician; low-dose amitriptyline for visceral pain.
-
Post-infective IBS
Symptoms that began after gastroenteritis - often responsive to low-FODMAP and rifaximin; a specific pattern the gastroenterologist will ask about.
-
Overlap with anxiety or low mood
The gut-brain axis is real. SSRI or low-dose TCA plus CBT or gut-directed hypnotherapy often outperforms drug-only treatment.
-
Red flag: alarm features
New-onset over 50, PR bleeding, weight loss, nocturnal symptoms, or family history of bowel cancer or coeliac - investigate before treating as IBS.
Treatment options
The full NICE CG61 toolkit - not just a prescription.
-
NICE first-line - diet and lifestyle
Regular meals, hydration, restrict caffeine, alcohol and fizzy drinks. Soluble fibre (ispaghula, oats). 150 min/week aerobic activity. Sleep and stress work.
-
Low-FODMAP diet (dietician-led)
Monash-developed, NICE-endorsed second-line. 4–6 week elimination, then structured reintroduction to identify your triggers. Around 70 per cent respond.
-
Antispasmodics
Mebeverine (Colofac), alverine (Spasmonal), hyoscine (Buscopan) or peppermint oil (Colpermin) - first-line for cramping across all subtypes.
-
IBS-D medications
Loperamide as-needed, low-dose amitriptyline (10–30mg nocte) for pain plus diarrhoea, rifaximin (Xifaxan) for the SIBO-overlap group, bile acid sequestrants if SeHCAT positive.
-
IBS-C medications
Ispaghula, macrogols (Movicol, Laxido), lactulose. Linaclotide (Constella, NICE TA318) or prucalopride (Resolor, NICE TA211) if refractory.
-
Gut-directed hypnotherapy
The Manchester Model (Peter Whorwell) - a 12-session evidence-based UK protocol. NICE-supported third-line and often transformative for refractory IBS.
-
CBT for IBS
A structured 8–12 session programme targeting symptom-related thoughts and behaviours. NICE-endorsed second-line psychological treatment.
-
Probiotics - a 4-week trial
Bifidobacterium infantis 35624 (Alflorex) is the most-studied. NICE accepts a four-week trial. Mixed evidence - helpful for some, not for others.
Safety and expectations
What to expect from IBS treatment - honestly.
IBS is chronic. Treatment reduces symptoms, it does not cure. Set expectations early, exclude the mimics, and take psychology seriously - outcomes get much better.
-
IBS is chronic - treatment reduces, does not cure
Realistic framing matters. Expect flares and remissions. The goal is fewer flares, milder symptoms, and a life not organised around the nearest toilet.
-
Exclude the mimics first
Coeliac disease, inflammatory bowel disease, bile acid diarrhoea and thyroid disease all masquerade as IBS. Bloods and faecal calprotectin are non-negotiable before treating blind.
-
Faecal calprotectin thresholds
Under 100 µg/g fits IBS. 100–250 is uncertain and needs a repeat. Over 250 warrants IBD workup - usually a gastroenterology referral and colonoscopy.
-
Low-FODMAP is not a forever diet
Strict elimination beyond 6–8 weeks harms the gut microbiome. Reintroduction is the point. Anyone selling you permanent restriction is selling you the wrong thing.
-
Low-dose TCA is not the same as antidepressant use
Amitriptyline at 10–30mg targets visceral pain and sleep, not mood. Doses for depression are 5–10 times higher. Worth explaining because the label puts patients off.
-
Rifaximin is for a specific subgroup
A 14-day course of Xifaxan 550mg tds can help IBS-D with likely SIBO overlap. It is not a routine first-line and needs specialist judgement.
-
Psychology is a treatment, not a last resort
Gut-directed hypnotherapy and CBT for IBS have some of the strongest evidence in the field. Offering them early, not last, changes outcomes.
-
FMT and vagus nerve stimulation are still research
Faecal microbiota transplantation and vagal stimulation for IBS are experimental. Some private clinics offer them; the evidence does not yet justify the price.
-
Red flags
New-onset over 50, PR bleeding, weight loss, nocturnal symptoms, family history of bowel cancer or coeliac - these need investigation, not an IBS label.
Reading your clinic letter
Your IBS management plan in four parts. Read the last one first.
Whichever combination of dietician, medication and psychology you end up on, the clinic letter keeps to the same shape.
A quiet reminder
Medical language is precise and can read coldly - we translate it for you.
If you would like us to talk you through the letter before your review, just ask.

Realistic expectations and review
Read this first: what improvement to expect and by when, what to do if it does not, and when the next review is booked.
Recognised by major UK insurers
Insurance cover for IBS treatment varies - gastroenterology and diagnostics are usually funded, dietician and psychology sometimes are, and hypnotherapy is often self-pay.
Frequently asked
Everything we get asked about IBS treatment.
Quick answers on cost, FODMAP, medication choice, hypnotherapy, and when specialist referral is warranted.
-
Can IBS be cured?
No - but it can be genuinely well-controlled. NICE-guided treatment across diet, medication and psychology reduces symptom frequency and severity so IBS stops running your life. Expect flares and remissions rather than a permanent fix.
-
What is the low-FODMAP diet, and does it work?
It is a dietician-led protocol developed at Monash University: a strict 4–6 week elimination of fermentable carbohydrates, then a structured reintroduction to identify your personal triggers. Around 70 per cent of people with IBS improve. NICE endorses it as second-line after simple dietary advice.
-
How much does private IBS treatment cost in the UK?
Roughly £250–£400 for an initial gastroenterology consultation, £120–£250 per session with a BDA-registered FODMAP dietician, £70–£150 per hypnotherapy session (12 sessions in a full course), and £80–£150 per CBT session. Faecal calprotectin is £70–£120 and coeliac bloods £120–£220.
-
Do I need a colonoscopy before starting treatment?
Not usually. NICE says treat as IBS if symptoms fit and alarm features are absent. A colonoscopy is warranted if you have PR bleeding, weight loss, nocturnal symptoms, a raised faecal calprotectin, are over 50 with new symptoms, or have a family history of bowel cancer or IBD.
-
Which medication works best for IBS?
It depends on subtype. IBS-D often responds to loperamide, low-dose amitriptyline, or rifaximin. IBS-C usually needs macrogols first, then linaclotide (Constella) or prucalopride (Resolor). Antispasmodics like mebeverine, alverine or peppermint oil help pain across subtypes.
-
Why is amitriptyline used for IBS if it is an antidepressant?
At 10–30mg it works on visceral pain and sleep, not mood. Depression doses are 5–10 times higher. It is one of the best-evidenced drugs for IBS pain with a diarrhoea component, and often improves sleep at the same time.
-
Is gut-directed hypnotherapy really evidence-based?
Yes. The Manchester Model developed by Prof Peter Whorwell has strong UK trial data. NICE lists it as a valid third-line treatment. It is not the stage-show version - it is a structured 12-session protocol targeting the gut-brain axis, and around two-thirds of refractory patients improve substantially.
-
What about probiotics - do they help?
Sometimes. Evidence is mixed. NICE suggests a four-week trial at a stated dose is reasonable. Bifidobacterium infantis 35624 (Alflorex) has the most data. If there is no benefit after four weeks, stop - do not keep spending on them indefinitely.
-
When should I be referred to a specialist?
Alarm features (bleeding, weight loss, nocturnal symptoms, new-onset over 50, family history), failure to respond to first- and second-line treatment, severe impact on quality of life, or diagnostic uncertainty.
