How to prepare for a GP or gastroenterologist appointment
Bowel appointments are short and symptoms are hard to describe on the spot. A couple of weeks of notes, a medicine list and a few written questions make the visit far more useful.

General information, not medical advice. This page can help you notice patterns and talk with a clinician. It cannot tell you what is causing a symptom.
Why a little preparation helps
MedlinePlus calls communication with your doctor one of the most important parts of getting good health care, and says being prepared helps you make the most of your visit, in person or by telehealth. For gut symptoms this matters even more, because the details doctors ask about are easy to forget once you are in the room.
Mayo Clinic makes a practical point: if you are ready to answer the doctor's questions quickly, there is more time left for the things you want to talk about. The NHS likewise suggests writing down details of your symptoms before a GP appointment to help you remember them.
What to track in the weeks before
NIDDK suggests tracking your bowel movements and what your stools look like for several days or weeks before your visit, and writing it down so you can share it. These are the details that come up again and again in the questions doctors ask:
| What to note | Why it comes up |
|---|---|
| How often you go each day or week | NIDDK lists how often you have a bowel movement among the first questions about constipation. |
| What your stool looks like, using a Bristol type number | NIDDK says doctors ask what your stools look like. A number from 1 to 7 is clearer than "loose" or "hard". |
| Any blood, red streaks on toilet paper, or black stools | NIDDK and Mayo Clinic both list questions about blood in or on your stool. |
| Pain and how it relates to going | NIDDK says doctors look at whether pain gets better or worse after a bowel movement. |
| Food and drink, with times | NIDDK suggests a food journal of what you eat, your symptoms, when they happen and which foods seem to make them worse. |
| Waking at night to go, fever, or weight loss without trying | Mayo Clinic lists these among the questions doctors may ask. |
An example week of notes
Mon: type 6 twice, urgent after coffee, cramps eased after going. Tue: type 4. Wed: type 6 three times, woke at 3 am once. No blood all week. Weight steady. Short, plain notes like these are easy to read aloud.
What to bring
Combining advice from MedlinePlus and Mayo Clinic, a useful appointment kit is:
- Your symptom notes, including symptoms that seem unrelated to the main problem (Mayo Clinic).
- A full medicine list. MedlinePlus suggests listing all medicines, herbs, vitamins and supplements, plus any allergies. For diarrhea, Mayo Clinic suggests including doses, and if you recently took an antibiotic, which one, for how long and when you stopped.
- Key personal information, such as major stress, recent life changes or travel (Mayo Clinic).
- Your medical and family history. Mayo Clinic says doctors may ask about family history of bowel disorders or colon cancer, and NIDDK mentions digestive diseases such as celiac disease, colon cancer and inflammatory bowel disease.
- Your questions, written down, so they do not get lost.
- A friend or relative, if you like. MedlinePlus and Mayo Clinic both suggest bringing someone to help remember what was said, or to take notes.
Ask about preparation when you book
Mayo Clinic suggests asking, when you make the appointment, whether there is anything you need to do in advance, such as fasting before certain tests or restricting your diet.
How to describe your symptoms
MedlinePlus suggests writing down a description of your symptoms that includes when they started, what makes them better and what makes them worse. It also asks you to be honest rather than saying what you think the doctor wants to hear, because your doctor needs to know what is really going on.
Compare two ways of saying the same thing. Vague: "My stomach has been off for a while." Specific: "Since early August I have had type 6 or 7 stools about three times a day, mostly in the morning. Cramps ease after I go. No blood. I have lost about 2 kilos without trying." The second version answers most of a doctor's first questions in a few sentences.
It can feel awkward to talk about poo. The NHS asks people to try not to be embarrassed, because doctors and nurses are used to talking about these symptoms.
Questions the doctor may ask you
Being ready for these is most of the preparation. Based on NIDDK and Mayo Clinic guidance for bowel symptoms, you may be asked:
- When did this start, and is it constant or does it come and go?
- How severe is it, and what makes it better or worse?
- Do foods, stress or your menstrual cycle seem to set it off?
- Have you seen blood, or black stools? Have you had fever or vomiting?
- Have you lost weight without trying?
- Does it wake you at night?
- What do you usually eat, and what medicines and supplements do you take?
- Have you recently taken antibiotics, traveled, or been around someone with diarrhea?
- Does anyone in your family have bowel problems or colon cancer?
- How much is it affecting your daily life, work or relationships?
Questions to ask your gastroenterologist
Mayo Clinic suggests writing your questions down before the visit, and MedlinePlus says to keep asking until you understand. Put the ones that matter most first, in case time runs short:
- What is the most likely cause of my symptoms?
- Are there other possible causes?
- Do I need any tests, and how do I prepare for them?
- Could a medicine or supplement I take be playing a part?
- Is this likely to be short term or long term?
- What is the best next step, and what are the alternatives?
- I have other health conditions. How can I manage them together?
- Should I change what I eat, or anything else day to day?
- What should I keep tracking before the next visit?
- What signs mean I should come back sooner or get urgent help?
- How and when will I get results, and who do I contact with questions?
- Is there printed material or a website you recommend?
What usually happens at the appointment
NIDDK says doctors start with your symptoms and your medical and family history, then do a physical exam, which usually means checking for bloating, listening to your abdomen with a stethoscope and tapping it to check for tenderness. The NHS says a GP may also ask to do a rectal examination. You can ask for a male or female doctor or nurse, and for someone else to be in the room.
Tests depend on your symptoms. NIDDK lists blood tests and stool tests, and in some cases a breath test or a camera test such as a colonoscopy. The NHS notes you may be given a home kit to collect a small poo sample. If you leave unsure about something, the NHS suggests writing down your questions and booking another appointment to go over them.
When not to wait for the appointment
A booked appointment weeks away is not the right place for urgent symptoms. The NHS says to ask for an urgent GP appointment if your poo is black or dark red or you have bloody diarrhea, and to call 999 or go to A&E (or your local emergency number) if you are bleeding non-stop from your bottom or see a lot of blood or large clots. Our when to see a doctor guide lists the other warning signs, including signs of dehydration.
Common questions
How do I prepare for a gastroenterologist appointment?
Track your bowel movements and what your stools look like for several days or weeks beforehand, as NIDDK suggests. Then write down your symptoms, a full list of medicines and supplements, relevant family history and your questions. MedlinePlus also suggests bringing someone with you to help take notes.
What should I tell my gastroenterologist?
Tell them when symptoms started, how often they happen, what your stools look like, and what makes things better or worse, which MedlinePlus recommends including. Mention any blood, black stools, fever, vomiting, weight loss without trying or night waking, since Mayo Clinic lists these among the questions doctors ask. Be honest, even about things that feel embarrassing.
Can I eat before a gastroenterology appointment?
Ask the clinic. Mayo Clinic suggests asking when you book whether you need to do anything in advance, such as fasting before certain tests. Follow the instructions the clinic gives you.
What happens at a first gastroenterologist appointment?
Usually a conversation about your symptoms, medical history and family history, followed by a physical exam of your abdomen, according to NIDDK. The doctor may then suggest blood or stool tests, or other tests depending on what they find.
What questions should I ask my gastroenterologist?
Good starting points from Mayo Clinic include the most likely cause of your symptoms, which tests you need and how to prepare, and whether to change your diet or routine. MedlinePlus adds asking for written instructions and how to contact the team later.
When to talk to a doctor
Contact a doctor promptly if you notice any of these. Get urgent help if you also feel faint, dizzy or very unwell.
