No. A gastroenterology consultation very often begins with a conversation, analysis of symptoms, previous test results, medications, diet and lifestyle — not with an automatic referral for gastroscopy or colonoscopy. Endoscopy is an important diagnostic tool, but it is not necessary for every patient at the first visit.
This article explains what a gastroenterology consultation involves, when a doctor may actually recommend gastroscopy or colonoscopy, and when blood tests, ultrasound, stool tests, trial treatment, dietary changes or observation may be enough. If you have digestive symptoms but are afraid of endoscopic examinations, start with a gastroenterology consultation.

Why are patients afraid of visiting a gastroenterologist?
Many patients postpone seeing a gastroenterologist because they immediately imagine gastroscopy, colonoscopy, anaesthesia, bowel preparation or unpleasant experiences they have heard about from other people. This fear is understandable, but it is often based on the mistaken assumption that a gastroenterology consultation automatically means an endoscopic examination.
In reality, the first visit to a gastroenterologist usually focuses on organising the problem. The doctor needs to understand what symptoms are present, how long they have lasted, what worsens them, what relieves them, what tests have already been performed and whether any alarm symptoms are present.
Only after this analysis is it possible to decide whether gastroscopy, colonoscopy, another test, medication, dietary changes, follow-up after a few weeks or referral to another specialist is needed.
“A gastroenterology consultation is not about sending every patient for gastroscopy or colonoscopy. First, we need to determine what the problem is, whether there are alarm symptoms and which test would actually change further management.”
— Dr Mateusz Jóźwiak, gastroenterologist
What does a standard gastroenterology consultation involve?
The foundation of a gastroenterology consultation is a detailed medical history. For the patient, this may sound “ordinary”, but in gastroenterology, the conversation often leads to very specific diagnostic decisions. Short-term indigestion is approached differently from chronic diarrhoea, reflux is approached differently from anaemia or bleeding.
During the visit, the doctor may ask about:
- abdominal pain — location, character, duration and relation to meals,
- heartburn, belching, reflux, hoarseness or cough,
- nausea, vomiting, feeling of fullness, bloating,
- diarrhoea, constipation or alternating bowel habits,
- blood in the stool, black stool or mucus,
- weight loss, weakness, fever, night-time symptoms,
- medications, especially painkillers, anti-inflammatory drugs, anticoagulants and antibiotics,
- previous test results, such as blood count, liver tests, ultrasound, calprotectin, Helicobacter pylori tests,
- family history, especially gastrointestinal cancers and inflammatory bowel diseases,
- diet, alcohol, stress, sleep and lifestyle.
Based on this, the gastroenterologist assesses whether the symptoms appear functional, inflammatory, infectious, metabolic, medication-related, reflux-related, hepatic, pancreatic, intestinal or require more urgent diagnostics.
What should you bring to the visit?
A good consultation is easier if the patient brings previous results. You do not need to have a complete set of tests — the doctor may order them after the visit — but anything already performed helps avoid repeating diagnostics unnecessarily.
It is worth bringing:
- blood count, CRP, liver tests, amylase/lipase, TSH, glucose — if previously performed,
- abdominal ultrasound, CT, MRI or previous endoscopy results,
- stool test results, such as occult blood, calprotectin, parasite tests,
- Helicobacter pylori test results, if performed,
- a list of medications and supplements,
- information about previous surgeries, hospitalisations and chronic diseases,
- a short note: when the symptoms started, how often they occur and what the patient associates them with.
If the patient has no test results, they can still attend the consultation. The gastroenterologist will help decide where to start the diagnostic process.
Does every symptom mean endoscopy?
| Symptom | Does it immediately require gastroscopy or colonoscopy? | What does the doctor usually assess? |
|---|---|---|
| Heartburn and belching | not always | duration, response to treatment, difficulty swallowing, weight loss, bleeding |
| Bloating and feeling of fullness | often not at the beginning | diet, bowel habits, intolerances, medications, alarm symptoms |
| Constipation | not always | age, duration, blood in stool, anaemia, weight loss, medications, diet |
| Diarrhoea | depends on the situation | duration, fever, blood, night-time symptoms, weight loss, calprotectin, infections |
| Abdominal pain | not always | location, relation to food and stool, ultrasound, blood tests, alarm symptoms |
| Blood in stool or black stool | often requires more urgent diagnostics | source of bleeding, blood count, age, accompanying symptoms, indications for endoscopy |
When may gastroscopy be needed?
Gastroscopy allows the doctor to examine the oesophagus, stomach and duodenum. It is a very important test, but it is performed when it can genuinely help with diagnosis or treatment. Not every patient with heartburn, indigestion or upper abdominal pain needs it immediately.
Gastroscopy may be recommended, for example, in case of:
- difficulty swallowing,
- painful swallowing,
- bleeding from the upper gastrointestinal tract, such as vomiting blood or black stool,
- iron-deficiency anaemia without a clear cause,
- unintentional weight loss,
- persistent vomiting,
- suspected peptic ulcer disease or complications of reflux,
- lack of improvement despite properly conducted treatment,
- follow-up of selected precancerous conditions or chronic diseases, if indicated.
If symptoms are mild, short-term and without alarm features, the doctor may first suggest treatment, laboratory tests, Helicobacter pylori testing, dietary modification or observation. The decision depends on age, symptoms, medical history and individual risk.
When may colonoscopy be needed?
Colonoscopy allows assessment of the large bowel and the terminal part of the small intestine. It may be used to diagnose bleeding, chronic diarrhoea, inflammatory bowel disease, polyps and colorectal cancer. It may also be a preventive test at a certain age or in patients with a family history.
Colonoscopy may be recommended, for example, in case of:
- blood in the stool or rectal bleeding that cannot be clearly explained,
- iron-deficiency anaemia without a clear cause,
- unintentional weight loss,
- persistent change in bowel habits, especially if it appeared recently,
- chronic diarrhoea, especially at night or with blood,
- suspected inflammatory bowel disease,
- positive faecal occult blood test or FIT,
- previous colon polyps,
- colorectal cancer in close relatives,
- colorectal cancer prevention according to age and risk factors.
At the same time, not every episode of diarrhoea, constipation or abdominal pain requires colonoscopy. In some patients, blood tests, stool tests, ultrasound, medication review, an elimination diet or trial treatment are performed first.
Alarm symptoms — when should you not delay the visit?
Some symptoms should prompt earlier contact with a doctor. They do not automatically mean a serious disease, but they do require sensible diagnostics. The worst option is treating yourself for months without a diagnosis.
Alarm symptoms include:
- blood in the stool, rectal bleeding or black, tarry stool,
- vomiting blood or coffee-ground vomit,
- difficulty swallowing or a feeling that food gets stuck,
- unintentional weight loss,
- anaemia, especially iron-deficiency anaemia,
- abdominal pain that wakes you at night or becomes worse,
- fever, night sweats, weakness,
- chronic diarrhoea, especially at night, with blood or weight loss,
- new, persistent change in bowel habits,
- a palpable abdominal mass,
- family history of colorectal cancer, stomach cancer or inflammatory bowel disease.
In such situations, the gastroenterologist may refer the patient more quickly for endoscopy or other diagnostics. The aim is not to “scare patients with tests”, but to safely exclude conditions that should not be missed.
Why is it not always worth doing tests “just in case”?
Many patients believe that the more tests they have, the better. In medicine, this is not always true. A good test is one that is justified, answers a specific question and may change further management. A test performed without indications may increase stress, generate incidental findings, lead to further procedures and not always improve patient safety.
This does not mean that gastroscopy or colonoscopy should be avoided. They are very valuable tests when needed. The point is to perform them at the right time, for the right reason and after discussion with the patient.
Rational diagnostics is not “saving on tests”. It is choosing a pathway that is medically justified and safe.
What can be done instead of endoscopy at the beginning?
In many patients, the gastroenterologist may start with less invasive steps. The choice of tests depends on symptoms, but often includes:
- blood count and deficiency parameters,
- CRP or other inflammatory markers,
- liver tests, bilirubin, pancreatic enzymes,
- TSH testing in constipation or diarrhoea,
- stool tests, such as calprotectin, occult blood, infectious tests,
- Helicobacter pylori testing,
- coeliac disease testing, if indicated,
- abdominal ultrasound,
- dietary modification, trial treatment or a symptom diary.
Sometimes only the results of these tests show whether endoscopy is needed. In other cases, alarm symptoms justify endoscopy straight away. This is why individual assessment is so important.
What if the patient is really afraid of gastroscopy or colonoscopy?
Fear of the examination is common and should not be dismissed. The patient may fear pain, the gag reflex, loss of control, anaesthesia, bowel preparation for colonoscopy or the result itself. A good consultation should make room for these concerns.
It is worth telling the doctor directly:
- “I am afraid of gastroscopy”,
- “I had a bad experience with colonoscopy”,
- “I am afraid of anaesthesia”,
- “I have been postponing the visit because I do not want endoscopy”,
- “I want to understand whether this test is really necessary”.
The gastroenterologist can then explain whether the test is needed, what alternatives exist, how preparation looks, whether sedation is possible and what the result can actually show. Sometimes after such a conversation it turns out that the test is not necessary at this stage. Sometimes the patient agrees to it more calmly because they understand its purpose.
“The patient has the right to be afraid of gastroscopy or colonoscopy. Our role is to explain whether the examination is really needed, what it is meant to show and what options are available. The patient’s fear should not be a reason to postpone diagnostics, but a topic for a calm conversation.”
— Dr Mateusz Jóźwiak, gastroenterologist
Common situations in a gastroenterology office
1. Heartburn and reflux
Not every patient with heartburn requires immediate gastroscopy. If symptoms are typical and there are no alarm symptoms, the doctor may start with lifestyle changes, medication and observation. Endoscopy becomes more important if there is difficulty swallowing, bleeding, weight loss, lack of improvement or other risk factors.
2. Abdominal pain
Abdominal pain may come from the stomach, intestines, bile ducts, pancreas, urinary system, reproductive organs, muscles or may be functional. Sometimes the first step is blood testing and ultrasound, not endoscopy.
3. Bloating
Bloating is common and may result from diet, constipation, intolerances, irritable bowel syndrome, microbiota disturbances, stress or gastrointestinal diseases. Colonoscopy is not always the first test. Accompanying symptoms are important.
4. Constipation
In constipation, the doctor assesses diet, fluid intake, physical activity, medications, thyroid disease, alarm symptoms and the patient’s age. In many people, regulating bowel movements is the foundation. Colonoscopy is considered if alarm symptoms appear, there is a sudden change in bowel habits or preventive indications are present.
5. Diarrhoea
In chronic diarrhoea, stool tests, blood count, CRP, calprotectin, infection history, diet, medications and night-time symptoms are important. Endoscopy may be needed, but it is not always the first step.

Frequently asked questions
Does a gastroenterologist immediately refer patients for gastroscopy at the first visit?
Not always. The gastroenterologist first takes a medical history, analyses symptoms and previous results. Gastroscopy is recommended when there are specific indications.
Is colonoscopy necessary for every abdominal pain?
No. Abdominal pain may have many causes. Sometimes the first step is blood testing, ultrasound, stool tests, trial treatment or observation. Colonoscopy is needed when specific indications are present.
When should I not delay seeing a gastroenterologist?
You should not delay the visit in case of bleeding, black stool, weight loss, anaemia, difficulty swallowing, persistent vomiting, severe pain, night-time diarrhoea or sudden change in bowel habits.
Can other tests be done before endoscopy?
Often yes. Depending on symptoms, the doctor may order blood tests, stool tests, abdominal ultrasound, Helicobacter pylori testing or other tests. Endoscopy is chosen according to the situation.
Is it worth telling the doctor that I am afraid of gastroscopy or colonoscopy?
Yes. This is important information. The doctor can explain whether the test is necessary, what alternatives exist, how preparation looks and how discomfort can be reduced.

Book a gastroenterology consultation →Summary
A gastroenterology consultation does not automatically mean gastroscopy or colonoscopy. In many cases, the first step is a detailed medical history, analysis of previous results, medical examination, laboratory tests, ultrasound, stool tests, trial treatment or dietary changes.
Endoscopy is a very important tool, but it should be performed when there are indications. Alarm symptoms such as bleeding, anaemia, weight loss, difficulty swallowing, chronic diarrhoea with general symptoms or persistent change in bowel habits require earlier assessment.
If you are postponing the visit because you are afraid of tests, it is worth starting with a conversation with a gastroenterologist. The purpose of the consultation is not only to order tests, but above all to choose diagnostics that are truly necessary and safe for the patient.
