What to Bring to Your Gastroenterologist Appointment

The average gastroenterologist appointment lasts about 15–20 minutes. If you spend the first 10 minutes trying to remember your symptoms, when they started, and what makes them worse, you've spent most of your appointment on setup rather than answers.

Preparation makes a measurable difference. Doctors in a 15-minute slot can do a lot more for you if you arrive organised. Here's exactly what to bring — and what to say when you get there.

1. A symptom summary document (1 page, prepared in advance)

The most useful thing you can bring is a concise written summary of your symptoms. One page. You'll be surprised how much clarity this creates — both for your doctor and for yourself.

Your summary should cover:

• What symptoms you have: bloating, cramping, diarrhoea, constipation, urgency, nausea, etc.
• When they started: as specifically as possible (after a holiday, after a particular illness, gradually over years)
• Frequency: how many days per week do you have symptoms? How many bowel movements per day on a bad day?
• Severity: how significantly do symptoms affect your daily life? Do they impact work, social events, travel?
• Pattern: time of day, before or after meals, relationship to stress, menstrual cycle correlation if relevant
• What makes it better: warmth, movement, fasting, any foods that seem safe
• What makes it worse: stress, specific foods, time of day, movement, eating at all

2. Your food and symptom log

If you've been tracking your food and symptoms — even for a week or two — bring it. Gastroenterologists are used to patients saying "I think dairy might be a trigger" based on vague memory. A structured log that shows three weeks of meals, symptoms, and severity ratings is a different level of evidence.

It shifts the conversation from "these are my guesses" to "here's what my data shows."

Even a rough log is better than nothing. A phone note with dated entries, a spreadsheet, a food diary app export — anything showing the connection between what you're eating and what you're experiencing is useful.

3. A medication and supplement list

Write out everything you're currently taking — prescription medications, over-the-counter medications, and supplements. Include dose and frequency.

Many medications affect gut function significantly: iron supplements (constipation), magnesium (loose stools), NSAIDs like ibuprofen (gut irritation), proton pump inhibitors (alter gut bacteria), certain antidepressants. Your gastroenterologist needs this information to interpret your symptoms correctly.

Don't assume they'll have an up-to-date record from your GP. Bring your own list.

4. Your previous test results

If you've had any relevant tests before — blood tests, stool tests, colonoscopy, endoscopy, ultrasound — bring the reports or at least note the dates and what was found.

Things particularly worth noting:

• Any IBD investigations (colonoscopy, calprotectin, CRP)
• Coeliac disease testing (TTG antibodies)
• Blood tests showing anaemia or nutritional deficiencies
• Stool testing for infections or blood

If tests came back normal, that's also useful — it rules things out and shapes the current investigation.

5. Your specific questions, written down

You'll forget at least one important question the moment you're in the consultation room. Write them down in advance.

Common important questions to consider:

• Should I have a colonoscopy or other investigations given my symptoms?
• Is there anything in my symptom pattern that concerns you?
• Should I be tested for coeliac disease before changing my diet?
• Is small intestinal bacterial overgrowth (SIBO) worth investigating?
• What treatment options are available for my subtype (IBS-D, IBS-C, IBS-M)?
• Should I see a dietitian for low-FODMAP guidance?
• Are there medications that might help while I work on dietary triggers?
• What symptoms should prompt me to come back urgently?

6. A description of your "red flags" awareness

Gastroenterologists are required to rule out serious pathology before diagnosing functional conditions like IBS. Help them do this quickly by being clear about whether you have:

• Blood in stool (bright red or dark/tarry)
• Unintentional weight loss
• Symptoms that wake you at night
• Fever accompanying gut symptoms
• Family history of colorectal cancer or IBD

If you have any of these, say so clearly at the start of the appointment. If you don't, it's also worth noting that — it helps the doctor move more quickly to the IBS conversation.

What to expect from a first appointment

A first gastroenterology appointment typically involves:

• Taking a full symptom and medical history
• Reviewing test results
• Potentially requesting further investigations (blood tests, stool tests, colonoscopy)
• Discussing a management plan

You may not get a definitive diagnosis at the first appointment. This is normal — IBS is a diagnosis of exclusion, meaning other conditions need to be ruled out first. The investigations can take weeks.

After the appointment

• Note down the key discussion points and any recommended next steps before leaving
• Ask for test referrals in writing if verbal instructions were given
• Continue your food and symptom tracking — data collected now will be useful at your follow-up
• Don't make major dietary changes before investigations are complete (especially coeliac testing — see the [low-FODMAP diet guide](/articles/fodmap-diet-explained/) for why this matters)
• Follow up if you haven't heard about test results within the expected timeframe

I've lived with IBS since 2018 and saw four gastroenterologists before I started tracking properly. Find My Triggers is what I wish I'd had from the start.
