A doctor's report isn't a diary or a narrative. It's a compressed document that conveys numbers, patterns, and warning signs in under 90 seconds of reading. Someone who brings a good IBS report to the clinic changes the course of the appointment — from "explain what's happening" to "let's discuss the options".
Why a structured report saves 15 minutes of clinic time
In a 15-minute slot, history-taking is the most expensive unit. Replacing it with a structured document leaves 11 minutes for the actual decision. Details in our 15-minute appointment article.
The DGVS S3 guideline (Layer 2021) recommends a standardised approach to IBS assessment: symptom course over at least three months, red-flag screening, differential diagnosis (coeliac, IBD, infection). For all these decisions the clinician needs data in comparable form — not "I've been better and worse" but Bristol distribution, IBS-SSS score, and trigger patterns.
The four mandatory sections of an IBS report
A useful IBS report has four core blocks — anything beyond that is garnish. Each block must be readable as one chart or one number, otherwise it doesn't belong on a one-page report.
- 1. Bristol distribution — frequency of the 7 types across the tracking weeks. Shows IBS subtype per Rome IV (Mearin 2016) (IBS-D, IBS-C, IBS-M, IBS-U).
- 2. Pain and bloating trend — line across calendar days, 0–10 scale. Shows frequency and intensity — the basis for the clinician's impact assessment.
- 3. IBS-SSS score — single number with baseline, current, and delta. The 50-point MCID threshold (Francis 1997 (Francis 1997)) shows whether changes are clinically relevant.
- 4. Red-flag status — explicitly checked list. Which red flags are negative (blood, weight loss, fever, nocturnal pain, anaemia, palpable mass), which are present. See red-flag article.
Optional but highly useful are three further blocks: trigger patterns (what correlates regularly with symptoms), medication list including OTC, and a question list with three to six concrete questions for the appointment.
Documenting Bristol distribution correctly
A Bristol distribution is meaningful from at least 2 weeks of daily logging. Three weeks is better, four weeks optimal. The clinic reads the distribution against fixed Rome IV thresholds:
- IBS-D (diarrhoea-predominant): >25 % type 6/7, <25 % type 1/2
- IBS-C (constipation-predominant): >25 % type 1/2, <25 % type 6/7
- IBS-M (mixed): >25 % type 1/2 AND >25 % type 6/7
- IBS-U: none of the above
Details on the scale and subtype classification in our Bristol article. For the report, a small bar chart with 7 columns (types 1–7) and percent frequency is enough — this visual is used internationally in gastroenterology.
IBS-SSS score: the one number that sums it up
The IBS-SSS by Francis, Morris, and Whorwell (Francis 1997) reduces the IBS experience to a number between 0 and 500 — higher = more severe. For the report you need:
- Baseline score (at the start of tracking or before an intervention)
- Current score (at the time of the report)
- Delta (current minus baseline) — with MCID marker: ≥50 points is considered clinically relevant
- Severity band: <75 remission, 75–175 mild, 175–300 moderate, >300 severe
A sample report sentence: "Baseline 320 (severe, 2026-02-15) → current 220 (moderate, 2026-04-15) → Δ −100 (MCID threshold exceeded)". Readable in one glance. Calculation and MCID details in our IBS-SSS article.
Trigger patterns and red-flag checklist
Trigger patterns are the real currency of pattern recognition. A good tracking app surfaces correlations like "onion + high stress → type 6 within 24 h in 3 of 3 incidents". For the report you want the three to five strongest correlations — no more, otherwise signal vs. noise becomes hard in the clinic.
The red-flag checklist is explicit: each of the six DGVS red flags is deliberately checked — "negative" or "positive". Only then does the clinic know for sure that the warning signs were reviewed, and which further diagnostics are indicated:
- Blood in stool / tarry black stool
- Unintended weight loss >5 % in 6 months
- Fever >3 days with bowel symptoms
- Nocturnal waking pain
- Anaemia symptoms (pallor, breathlessness, fatigue)
- Palpable mass or unusual lymph nodes
Plus context factors: age >50 (first onset), positive family history for IBD, coeliac, or colorectal cancer. All placement details in our red-flag article.
Template: what a good one-page report looks like
An example that fits on a single A4 page — readable in 90 seconds. Italic parts are placeholders; in the real template they carry actual values:

How DarmKompass generates this PDF
Manually assembling from several apps is slow and error-prone. darmkompass generates the one-page report automatically from your logging data: Bristol distribution, pain curve, IBS-SSS with MCID marker, red-flag status as checklist, trigger patterns as top-3 correlations, medication list, and a customisable question list. Three clicks under "Export → Doctor PDF", ready to print or attach to the clinic's patient portal.
The report does not replace medical judgement — it is the input material that gets the clinic to a decision faster. Whether the decision is "continue" or "new diagnostics" is the clinician's job. Your job ends with the preparation.
