Gastroesophageal reflux disease, or GERD, is a condition in which stomach contents flow back into the oesophagus and cause troublesome symptoms, most commonly heartburn and regurgitation, meaning the return of acidic or bitter contents into the throat or mouth. In some patients, symptoms are occasional, but in others they return regularly and disturb sleep, eating, work and everyday functioning.
This article explains what reflux is, which symptoms should prompt a consultation, when gastroscopy is needed, what role lifestyle and stress play, and why treatment should not consist only of “taking acid medication”. If symptoms persist, recur or affect everyday life, it is worth booking a gastroenterology consultation.

What is gastroesophageal reflux disease?
Reflux means the backflow of stomach contents into the oesophagus. Short episodes of reflux may occur physiologically, especially after a large meal. We speak about gastroesophageal reflux disease when reflux causes troublesome symptoms or leads to complications, such as oesophagitis.
Most often, patients describe heartburn, burning behind the breastbone, a sour taste in the mouth or regurgitation after eating or when lying down. Sometimes, however, the picture is not typical. The patient may report hoarseness, cough, a feeling of a lump in the throat, belching, upper abdominal pain or worsening sleep.
In gastroenterological practice, it is important not only to diagnose reflux, but also to determine whether the symptoms really result from GERD or from another cause: functional dyspepsia, peptic ulcer disease, oesophageal motility disorders, oesophageal hypersensitivity, ENT conditions or cardiac problems.
“Reflux does not always mean the same thing in every patient. In one person, typical heartburn after meals dominates; in another, cough, hoarseness or upper abdominal pain may be the main problem. That is why we first need to take a good history, and only then decide whether treatment is enough or diagnostics are needed.”

The most common symptoms of reflux
The typical symptoms of gastroesophageal reflux disease are fairly characteristic, but their severity may vary greatly. In some patients they occur a few times a month, while in others almost every day.
The most common GERD symptoms include:
- heartburn, meaning a burning sensation behind the breastbone,
- regurgitation of acidic or bitter contents into the throat or mouth,
- a sour taste in the mouth,
- belching,
- a feeling of fullness after meals,
- pain or discomfort in the upper abdomen,
- worsening symptoms after a large, fatty or late meal,
- worsening symptoms when lying down or bending forward,
- waking up at night because of burning or regurgitation.
If symptoms occur frequently, require regular medication without consultation or return after stopping treatment, it is worth discussing the situation with a gastroenterologist.
Extra-oesophageal symptoms — when can reflux “imitate” other diseases?
In some patients, reflux does not cause classic heartburn. Instead, symptoms appear in the throat, larynx or airways. This can be misleading, because the patient may first see an ENT specialist, pulmonologist or family doctor.
Symptoms that may coexist with reflux include:
- chronic cough,
- hoarseness, especially in the morning,
- a feeling of a “lump in the throat”,
- frequent throat clearing,
- burning in the throat,
- recurrent throat irritation,
- a feeling of mucus or obstruction despite no infection,
- worsening symptoms after eating or at night.
However, caution is needed: not every cough, hoarseness or throat problem means reflux. Such symptoms may have many causes, so treating them “as reflux” without assessing the whole clinical picture may be insufficient.
Symptom — what can it mean?
| Symptom | Possible connection with reflux | When not to delay? |
|---|---|---|
| heartburn after meals | typical GERD symptom | when it occurs often or requires constant treatment |
| regurgitation into the mouth | common reflux symptom | when choking, night symptoms or reduced quality of life occur |
| hoarseness and cough | may coexist with reflux | when they persist despite treatment or have another possible cause |
| chest pain | may sometimes be confused with heartburn | requires urgent assessment if it may be cardiac in nature |
| difficulty swallowing | may indicate a complication or another disease | this is an alarm symptom — it requires diagnostics |
Alarm symptoms — when should gastroenterology not wait?
Most patients with heartburn do not have a dangerous disease, but there are symptoms that should not be explained as ordinary reflux without diagnostics. Their presence may indicate the need for faster medical assessment and gastroscopy.
Alarm symptoms include:
- difficulty swallowing,
- pain when swallowing,
- unintentional weight loss,
- gastrointestinal bleeding, coffee-ground vomiting or black stools,
- iron deficiency anaemia,
- recurrent or persistent vomiting,
- progressive worsening of symptoms,
- a palpable lump in the upper abdomen,
- new dyspeptic symptoms in an older patient,
- chest pain that cannot safely be considered heartburn.
In such situations, it is not worth changing medications on your own for many weeks. First, it is necessary to determine whether the symptoms really result from reflux and whether there are indications for more urgent diagnostics.
Why does reflux occur?
GERD usually does not have one single cause. Most often, it results from a combination of mechanical factors, lifestyle, body weight, diet, hiatal hernia, eating habits, sleep and individual oesophageal sensitivity.
Factors that may contribute to reflux include:
- weakening of the anti-reflux barrier between the stomach and oesophagus,
- hiatal hernia,
- overweight and obesity, especially abdominal obesity,
- large and fatty meals,
- eating late in the evening, shortly before sleep,
- alcohol, smoking and some irritating drinks,
- pregnancy,
- some medications,
- long-term stress and tension, which may intensify symptom perception,
- oesophageal hypersensitivity or coexisting functional gastrointestinal disorders.
It is worth emphasising that in one patient the main problem may be excess weight and late eating, in another hiatal hernia, and in another oesophageal hypersensitivity and emotional tension. That is why treatment should be individualised.
Stress and reflux — an important factor, but not the only explanation
Patients often notice that reflux symptoms worsen during periods of stress, lack of sleep, tension, rush or psychological overload. This is a real experience. The nervous system affects gastrointestinal motility, pain perception, muscle tension, sleep and the body’s response to signals from the oesophagus.
However, this does not mean that reflux is “imaginary” or that everything is “caused by stress”. That is too much of a simplification. Stress may intensify symptoms, increase awareness of bodily signals, worsen sleep, affect eating patterns and make treatment more difficult. But it should not replace diagnostics, especially when alarm symptoms are present.
In some patients, it may be helpful to combine gastroenterological treatment with work on sleep, tension reduction, regular meals, physical activity and — when indicated — psychological support. Such an approach does not make symptoms “less medical”; it simply better takes into account the interaction between the brain and the digestive tract.
“If a patient says that reflux worsens with stress, this should not be dismissed. However, we must be careful not to attribute everything to the psyche. First, we assess symptoms, red flags and response to treatment, and only then build a plan.”
— Dr Mateusz Jóźwiak, gastroenterologist
Does reflux always require gastroscopy?
No. Not every person with heartburn needs gastroscopy immediately. In patients with typical symptoms and no alarm symptoms, the doctor may often start with conservative treatment, lifestyle modification and observation of response to therapy.
Gastroscopy may be needed if:
- alarm symptoms are present, such as difficulty swallowing, weight loss, bleeding or anaemia,
- symptoms do not improve despite properly conducted treatment,
- symptoms quickly return after stopping medication,
- oesophagitis, stricture, Barrett’s oesophagus or other complications are suspected,
- the clinical picture is not typical and other causes need to be excluded,
- before planned procedural or surgical treatment, confirmation of the diagnosis is necessary.
A simple rule is worth remembering: gastroscopy is not a “punishment” for reflux and not a mandatory ending to every visit. It is a test performed when it can realistically change further management.
What does a gastroenterology consultation for reflux look like?
The consultation begins with a detailed medical history. The doctor asks about the nature of symptoms, duration, connection with meals, body position, sleep, stress, medications, diet and previous treatment. It is also important to determine whether alarm symptoms are present.
During the visit, the gastroenterologist may discuss:
- whether the symptoms are typical for GERD,
- whether gastroscopy is needed,
- whether medications were taken at the right dose and at the right time,
- how long to continue treatment and when to modify it,
- which lifestyle changes make the most sense for a given patient,
- whether symptoms may have a cause other than reflux,
- whether additional tests are needed, such as pH monitoring or oesophageal manometry in selected situations.
A well-conducted consultation is not just about prescribing “acid medication”. Its goal is to determine whether the diagnosis is likely, what factors intensify symptoms and what treatment plan will be safe and realistic.
Reflux treatment — what really matters?
GERD treatment usually includes several elements. In some patients, lifestyle changes and short pharmacological treatment are enough. In others, longer therapy, recurrence control, diagnostics or procedural treatment in selected cases may be needed.
In reflux treatment, the following may matter:
- weight reduction in patients with overweight or obesity,
- avoiding large meals late in the evening,
- not lying down directly after eating,
- avoiding individual products that trigger symptoms,
- limiting alcohol and smoking,
- elevating the head of the bed in patients with night symptoms,
- regular meals and calmer eating,
- pharmacological treatment if recommended by the doctor,
- proper use of medications, especially proton pump inhibitors,
- stress reduction, improved sleep and physical activity if these are important aggravating factors.
Proton pump inhibitors, or PPIs, are often used in GERD treatment. However, it is important to take them as recommended by the doctor — usually before a meal, not randomly during the day. If the medication does not work, the problem is sometimes not the medication itself, but the dose, timing, lack of GERD diagnosis or coexistence of another disorder.
What can the patient check before the visit?
| When are symptoms strongest? | after eating, at night, when bending, during stress, after coffee, alcohol or fatty meals |
| Are alarm symptoms present? | difficulty swallowing, weight loss, bleeding, anaemia, persistent vomiting |
| What medications were used? | name, dose, time of taking and duration of use matter |
| Do symptoms return after stopping medication? | this is important information when planning further diagnostics |
| Could the pain be cardiac? | chest pain, shortness of breath, sweating or radiating pain require urgent assessment |
Frequently asked questions
Does reflux always mean too much acid?
Not always. Symptoms may result from regurgitation, oesophageal hypersensitivity, motility disorders, hiatal hernia or other problems. That is why a lack of full improvement after “acid medication” does not always mean that only the dose needs to be increased.
Is gastroscopy necessary with reflux?
Not in every patient. Gastroscopy is particularly important in the presence of alarm symptoms, lack of improvement after treatment, recurrence after stopping medication or suspected complications.
Can stress worsen reflux?
Yes, stress may intensify symptom perception, affect sleep, eating patterns and digestive tract function. However, this does not mean that symptoms are “imaginary” or that diagnostics can be skipped when red flags are present.
What helps most with reflux?
It depends on the patient. Weight reduction, avoiding late large meals, not lying down after eating, limiting individual triggers and properly selected pharmacological treatment are often important.
Can PPIs be taken continuously?
In some patients, longer treatment is justified, but it should be periodically assessed by a doctor. It is important to use the lowest effective dose when such a regimen is possible and to determine why symptoms return.
When should I see a gastroenterologist?
It is worth seeing a gastroenterologist if symptoms are frequent, recur, disturb sleep, require regular medication, do not improve despite treatment or are accompanied by alarm symptoms.
Do heartburn, regurgitation, hoarseness or cough return despite treatment?
Do not assume that “this is just how it has to be”. Start with a gastroenterology consultation and determine whether the symptoms truly result from reflux.
Book a gastroenterology consultation →Summary
Gastroesophageal reflux disease may cause heartburn, regurgitation, sour taste, upper abdominal pain, hoarseness, cough and sleep disturbance. In many patients, symptoms can be controlled effectively, but it is important to determine whether GERD is truly the cause or whether another condition is responsible.
Not every case of reflux requires gastroscopy, but alarm symptoms, lack of improvement after treatment, recurrence after stopping medication or an atypical clinical picture should prompt deeper diagnostics. Stress may worsen symptoms, but it should not be treated as the only explanation without medical assessment.
If reflux symptoms affect everyday functioning, sleep or eating, book a gastroenterology consultation. The doctor will help determine whether treatment, gastroscopy, a change in how medications are taken or further diagnostics are needed.
