Patient Script
For the friend playing the patient role
Character Overview: You are Hollie Drummond, a 25 year old trainee solicitor. Six weeks ago you started your two year training contract in the property team of a commercial law firm in Leeds. The hours are long, there are client meetings most days, and the firm decides at the end of the two years which trainees it keeps. You share a flat with your friend Tamsin. Your parents and younger brother live in Nottingham.
In the week you started the job your bowels changed. You now go four or five times a day, the stools are loose, and you have to rush. You have lost about half a stone without trying. You are sure it is stress, because the timing fits so neatly and because your mum has had a "nervous tummy" for years and says you have inherited her stomach. You are calling from a glass meeting pod at the office on your lunch break. You are bright, upbeat and a little brisk, want a quick fix and play things down, but are more worn out and embarrassed than you let on.
You do not volunteer the weight loss, the night time trips to the toilet, the mouth ulcers or the near accident on the train unless the doctor asks about those areas.
Opening Sentence: "Hi, thanks for calling me back. So, since I started my new job my stomach's been all over the place and I'm back and forth to the loo all day. I'm pretty sure it's just stress, so I was hoping you could give me something for IBS."
History if Asked (Data Gathering Phase)
- ●How often and what it is like: "Four times a day usually, sometimes five. It's loose, sort of like porridge, and on bad days it's like water. I used to go once a day, regular as clockwork." It began the week she started at the firm, every day, with no normal day since.
- ●Rushing to the toilet (if asked about urgency or accidents): "When it comes, it comes. I always need to know where the nearest loo is." If asked whether she has ever not made it in time, her voice drops: "Last Tuesday on the train in, I honestly thought I wasn't going to make it. I got off two stops early and ran into a café. I made it, just. I haven't told anyone that."
- ●Night time (if asked whether it wakes her): "Most nights, yes. I'm up once, sometimes twice, in the night. Before all this I'd sleep straight through."
- ●Tummy pain (if asked): "Crampy, around my belly button and down on the right a bit, usually an hour or so after I've eaten. Going to the loo helps a little."
- ●Blood, slime, dark or greasy stools (if asked): "No, never any blood, and I do look. No slime, not black, just brown and loose. Nothing greasy or floating. It flushes away fine."
- ●Weight (if asked): "I've lost about half a stone. I'm normally about nine stone eleven and I was nine stone four on Tamsin's scales at the weekend." She has not been trying: "I'm eating normally. My mum said I looked thin when I went home and that threw me a bit." Appetite fine, no diets.
- ●What she has tried (if asked about medicines or remedies): "I bought loperamide from the supermarket. I take two before a big client meeting, so two or three days a week for the last three weeks. It helps for the meeting, but it all comes back the next day." No laxatives or painkillers.
Ideas, Concerns, Expectations
Gating note: Hollie does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks is going on, what is worrying her, or what she was hoping for.
- ●Ideas: She is convinced it is stress and that she has her mum's stomach. "It's the job, it has to be. It started the same week. And my mum's had IBS for years."
- ●Concerns: Work. She is six weeks into a contract and cannot be the trainee who is always off or always running out of meetings. "I can't be the one who's always off sick. They decide who they keep at the end and everyone's watching the new trainees." If the doctor explores further, a quieter worry comes out: "The weight thing's been bugging me a bit, if I'm honest. I didn't think stress did that so quickly."
- ●Expectations: She wants a tablet to get her through the working day, like her mum's peppermint capsules or something stronger, and would rather not have many appointments.
If Asked: Medical History and Medications
Gating note: Hollie answers each of these plainly when the doctor asks about it.
- ●Past health: Always well, bowels totally normal before this. Coil fitted two years ago, periods light, nothing changed, cannot be pregnant.
- ●Other medicines and allergies: Only the loperamide. No antibiotics for years. No allergies.
- ●Family history: Mum has IBS and Dad has high blood pressure. Her younger brother is fine. Nobody has had bowel cancer, inflammatory bowel disease, coeliac disease or serious bowel problems.
Social History and Lifestyle Impact
Gating note: Hollie shares this naturally when talking about work and how she is managing, bit by bit and not as a speech.
- ●Work: A big completion deadline at the end of the month.
- ●Lifestyle impact: "I plan my whole day around where the toilets are. I sit at the end of the table in meetings so I can slip out. I've stopped going to the gym, and I'm shattered by the afternoon."
- ●Alcohol, caffeine and smoking: Three medium glasses of wine on Thursdays and a couple at the weekend. Three or four flat whites a day. Never smoked, no drugs.
- ●Travel and contacts: No travel abroad for about ten months. Nobody at home or work has had a stomach bug.
- ●Diet: Meal deal at her desk for lunch, proper tea at night. No food makes it worse, including milk or bread.
If Asked: Associated Symptoms
Gating note: Hollie answers briefly, in a sentence or two.
- ●If asked about mouth ulcers or a sore mouth: "Oh, yes, loads this last month. Two or three at a time, inside my lips and under my tongue. They clear up in about a week and then new ones come. I put that down to late nights and too much coffee." No single ulcer has lasted more than a few weeks.
- ●If asked about tiredness: "I'm wiped out. I thought that was the hours."
- ●If asked about the back passage: "It's a bit sore from wiping so much. No lumps or anything coming out."
- ●If asked about mood: "I'm stressed with work, obviously, but I'm not low."
- ●All of the following are negative: fever, shivers or night sweats, joint pain or swelling, sore or red eyes, rashes or tender lumps on the legs, nausea or vomiting, a swollen tummy (only "a bit gurgly"), dizziness or fainting, any change in how much she drinks or passes urine, and a racing heart, shakiness or feeling hot (her heart only races after too much coffee).
Responses to Management (The Negotiation Phase)
- ●If the Doctor says it does not sound like stress or IBS and needs looking into:
- ●Reaction: Taken aback and a little defensive. "Really? But it started literally the week I started work. Isn't that a bit of a coincidence?" If the doctor explains which parts do not fit stress, she goes quieter: "I suppose the waking up at night is weird. And the weight. I'd just put it all down to being run off my feet." If the doctor simply offers an IBS tablet she is pleased: "Perfect, that's exactly what I was after."
- ●If the Doctor asks her to stop or avoid the loperamide:
- ●Reaction: Alarmed. "But what do I do before a client meeting? That's the only thing that gets me through." Once the risk is explained: "Okay, I didn't know that. I thought they were just harmless supermarket tablets." She agrees if she has a practical plan for meetings.
- ●If the Doctor arranges tests or an examination:
- ●Reaction: Practical. Blood tests: "Can I get them done early, before work? What are they looking for?" Advised to keep eating gluten: "I wasn't planning to change what I eat, but why does that matter?" Stool test: "Oh God. Do I have to bring it in? I can't exactly carry it round the office." Examination: "Could it be this week, early morning?" If it may include the back passage: "Could it be a female doctor, or someone else in the room?" If asked to press on her own tummy she declines: "I'm in a glass meeting pod. Can I come in?"
- ●If the Doctor says she needs a hospital bowel specialist, a camera test or A&E today:
- ●Reaction: Worried about work. Specialist: "How soon? I've literally just started this job. Is it that serious?" Camera: "Am I awake for that?" A&E: "Today? I feel alright. Is that really necessary?"
- ●If the Doctor says what it could be:
- ●Reaction: She asks directly once a plan is made: "So if it's not stress, what do you actually think it is?" If inflammation of the bowel is named, she is frightened: "Isn't that the one where people end up with a bag? Would I be ill on and off for the rest of my life?" She settles with an honest, hopeful answer and a clear next step. If gluten is mentioned: "So I'd have to give up sandwiches?" She is reassured that nothing changes until it is confirmed.
- ●If the Doctor gives safety netting, work advice and a plan for results:
- ●Reaction: To "get back in touch if it gets worse": "Worse how, though? I'm already going four times a day." To specific warning signs: "Okay, blood or a temperature, ring the same day. Can you send me that in a text?" To a fit note: "Would work have to know what it's for? I don't want to be the trainee with the bowel problem." She is open to it if told what it would say. On results: "Will you ring me, or do I have to chase?"

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Hollie is 25 with six weeks of continuous loose stools, four or five a day, urgency, crampy pain, about half a stone of weight loss (roughly 5% of body weight), waking most nights to open her bowels, and recurrent mouth ulcers.
- ●She has an explanation ready: the symptoms began the week she started a demanding contract, and her mother has irritable bowel syndrome (IBS). She asks for an IBS tablet. The timing is the trap: neither stress nor a parent with IBS explains nocturnal stools, weight loss or mouth ulcers.
- ●Model answer: recognise an organic picture, say so honestly, stop the loperamide, send bloods including coeliac serology and a faecal calprotectin, see her in person within days, refer urgently to gastroenterology, set a fixed results review, safety net specifically and support her at work.
- ●Also acceptable: sending the urgent referral now, or as soon as the first results return within about a week; adding a faecal immunochemical test (FIT) and a stool culture; seeing her the same day. Not acceptable: IBS treatment instead of investigation, or A&E for a systemically well patient.
Why This Is Not IBS
- ●NICE CG61 advises considering IBS when symptoms have been present for at least six months, and CKS makes the diagnosis only after at least six months of typical symptoms once alternatives are excluded. Hollie has had six weeks.
- ●NICE CKS on chronic diarrhoea lists red flags needing investigation or referral: unexplained weight loss, rectal bleeding, iron deficiency anaemia, raised inflammatory markers, nocturnal or continuous diarrhoea, and fever, tachycardia or dehydration. Hollie has two on history alone. CKS on IBS advises discussion with or referral to gastroenterology for atypical features such as nocturnal diarrhoea.
- ●Stress can worsen bowel symptoms and acknowledging that matters, but it is not a reason to skip investigation.
The Differential Diagnosis in a Young Adult
- ●Crohn's disease: CKS advises suspecting it with unexplained diarrhoea lasting more than 4 to 6 weeks, nocturnal diarrhoea, abdominal pain, fatigue, weight loss, aphthous ulcers, perianal disease and extra intestinal features in joints, eyes and skin. Incidence peaks between 15 and 30 years. Right lower pain after meals with weight loss fits ileal disease.
- ●Ulcerative colitis: usually bloody diarrhoea, so less likely here.
- ●Coeliac disease: NICE NG20 recommends serological testing for persistent unexplained gastrointestinal symptoms, prolonged fatigue, unexpected weight loss or severe or persistent mouth ulcers. Hollie meets several.
- ●Hyperthyroidism: weight loss and loose stools with palpitations and tremor.
- ●Others: infection (Giardia after travel, C. difficile after antibiotics; she has had neither), laxative misuse or an eating disorder, caffeine, bile acid diarrhoea and microscopic colitis. Colorectal cancer is rare at 25, with no bleeding, mass or anaemia.
History and Examination
- ●Ask directly about weight, night time stools and mouth ulcers, because patients rarely volunteer them. Screen for extra intestinal features, perianal symptoms, infection risks, medicines including over the counter anti diarrhoeals, thyroid symptoms and family history.
- ●Mouth ulcers in crops that heal within a week or two are aphthous. A single ulcer lasting more than 3 weeks is different: NICE NG12 advises considering a suspected cancer pathway referral for oral cancer.
- ●A telephone consultation cannot complete the assessment. CKS advises abdominal examination and, if acceptable, digital rectal examination, with measured weight and BMI. Arrange a face to face review within days, offering a chaperone.
Blood Tests and Coeliac Testing
- ●CKS recommends in chronic diarrhoea: full blood count, urea and electrolytes, liver function including albumin, calcium, B12, folate, ferritin, thyroid function, ESR, CRP and coeliac serology. Normal bloods do not close the question, because results can be normal in active Crohn's disease.
- ●NICE NG20: laboratories test total IgA and IgA tissue transglutaminase (tTG) first, use IgA endomysial antibodies if tTG is weakly positive, and consider IgG based tests if IgA is deficient. Without a total IgA a negative tTG can be falsely reassuring.
- ●Testing is accurate only while gluten is eaten: some gluten in more than one meal every day for at least 6 weeks before testing, and no gluten free diet until a specialist has confirmed the diagnosis, even if serology is positive. Positive serology means referral for biopsy; negative serology with continuing suspicion still means specialist assessment.
- ●Pitfall: CKS lists gluten as a possible trigger of aphthous ulcers. Do not suggest cutting it out before coeliac testing is complete.
Faecal Calprotectin and Stool Tests
- ●Calprotectin is released by neutrophils, so stool levels reflect bowel wall inflammation. NICE HTG320 (formerly DG11) recommends it to help distinguish IBD from IBS in adults with recent onset lower gastrointestinal symptoms when specialist assessment is being considered and cancer is not suspected. CKS applies it to people under 40.
- ●Cut offs are set locally. One national pathway treats below 100 micrograms per gram as IBS very likely, repeats results of 100 or more, then refers routinely at 100 to 250 and urgently above 250. Anti inflammatory painkillers can raise it and some people with IBD fall below it, so in Hollie a normal result would not make her weight loss and night time stools functional.
- ●Send stool microscopy and culture to exclude infection.
- ●NICE NG12 recommends offering a quantitative FIT to adults with a change in bowel habit, with no lower age limit; refer if 10 micrograms of haemoglobin per gram of faeces or more. HTG690 found too little evidence on FIT under 40, and CKS uses calprotectin in under 40s when cancer is not suspected, so FIT is reasonable but its omission is not a failing.
How Urgent? Choosing the Disposition
- ●Emergency admission: CKS reserves this for suspected IBD with bloody diarrhoea, fever, tachycardia or hypotension. Severe pain, a distended tender abdomen or significant dehydration also call for same day hospital assessment.
- ●Urgent gastroenterology referral: CKS advises urgent referral for suspected Crohn's disease that does not need admission, because early treatment improves outcomes. NICE QS81 says people with suspected IBD should have specialist assessment within 4 weeks.
- ●For Hollie: urgent gastroenterology referral, with bloods, calprotectin and stool culture in parallel and a face to face assessment within days. The referral can go now or when the first results return. She does not need A&E today, and a routine referral or a trial of IBS treatment would leave suspected IBD unassessed for too long.
Why Not Loperamide or IBS Treatment Now
- ●CKS advises not prescribing anti diarrhoeals when the diagnosis is uncertain, because they can precipitate toxic megacolon in ulcerative colitis. The BNF lists active ulcerative colitis and bacterial enterocolitis as contraindications. Loperamide also hides the symptoms that guide urgency.
- ●Shop bought loperamide is licensed for attacks lasting up to 48 hours, and in IBS packs only for IBS a doctor has diagnosed. Six weeks of daily symptoms is outside this.
- ●NICE CG61 makes loperamide, antispasmodics and peppermint oil IBS treatments. They belong after an organic cause is excluded, not instead of investigation.
- ●For the ulcers CKS suggests benzydamine or chlorhexidine mouthwash. Advise avoiding ibuprofen and similar painkillers while she is investigated, since they can aggravate bowel inflammation.
Results, Safety Netting and Work
- ●Fix a results review within about a week. Act on each result: positive coeliac serology means referral for biopsy while she keeps eating gluten; raised calprotectin, inflammatory markers, anaemia or low albumin support the urgent referral; normal results still need specialist discussion, because CKS advises referral when someone under 40 lacks typical functional symptoms.
- ●Safety net: same day contact or NHS 111 for blood in the stool, fever, severe or constant pain, marked rise in frequency, vomiting, dizziness, fainting or very little urine; 999 for collapse or severe pain with a swollen tender abdomen.
- ●People can self certify for 7 days. A fit note can say she "may be fit for work taking account of the following advice", suggesting adjustments such as toilet access. DWP guidance allows a less precise diagnosis if revealing it would harm her position. A confirmed long term condition such as Crohn's disease may count as a disability under the Equality Act 2010, with a duty on her employer to make reasonable adjustments.
Common Mistakes in This Station
- ●
Accepting the stress explanation because the timing fits, and prescribing an antispasmodic, peppermint oil or loperamide.
- ●
Not asking about weight, night time stools or mouth ulcers.
- ●
Calling it IBS after six weeks despite red flags.
- ●
Endorsing her regular loperamide while the diagnosis is uncertain.
- ●
Advising her to cut out gluten before the coeliac test, or ignoring total IgA.
- ●
Omitting faecal calprotectin, or planning to label her IBS if it is normal.
- ●
Referring routinely, or "reviewing in six weeks", instead of urgently.
- ●
Sending a well patient to A&E, or managing her entirely by phone.
- ●
Vague safety netting.
- ●
Ignoring her fear for her training contract, or answering her question about "ending up with a bag" with false reassurance or frightening certainty.
