Internal Medicine (내과) is generally the first department to see for heartburn, as it covers most digestive tract concerns including acid-related symptoms. If further investigation is needed, you may be referred to a Gastroenterology specialist (소화기내과) within the same or a larger facility.
Which department
- 1Internal Medicine (내과)Internal Medicine physicians handle a broad range of symptoms including heartburn, indigestion, and acid reflux at the primary care level. They can evaluate whether the symptom is likely related to the esophagus, stomach, or another organ system, and coordinate further steps if needed. — First / second line: This is generally the right starting point at a local clinic (의원). If your symptoms are persistent, recurring, or accompanied by other concerns, the internist may refer you to a specialist or a larger hospital (병원).
- 2Gastroenterology (소화기내과)Gastroenterology focuses specifically on the digestive system, including the esophagus and stomach, which are the most common sources of heartburn. This department typically handles cases that require more detailed evaluation of the digestive tract. — First / second line: You would generally be referred here from Internal Medicine when symptoms are chronic, unexplained, or when the physician considers a closer look at the esophagus or stomach to be appropriate. In some cases, patients with a clear prior history may visit this department directly at a hospital (병원 or 종합병원).
- 3Cardiology (심장내과)Heartburn-like chest discomfort can sometimes be difficult to distinguish from cardiac-related pain, so Cardiology may be involved when a heart-related cause needs to be ruled out. An Internal Medicine doctor will typically guide whether this referral is appropriate. — First / second line: This is not usually the first stop for heartburn, but if your chest discomfort is unusual in character or accompanied by symptoms like shortness of breath or radiating pain, a doctor may recommend cardiac evaluation alongside digestive workup.
Go to the ER / call 119 if
If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).
- Sudden, severe chest pain that feels crushing, squeezing, or radiating to the arm, jaw, or back — go to the emergency room or call 119 immediately rather than choosing a department.
- Vomiting blood or passing black, tarry stools, which may indicate bleeding in the upper digestive tract.
- Difficulty swallowing or a feeling that food is getting stuck in the throat or chest.
- Significant unintentional weight loss occurring alongside heartburn symptoms.
- Heartburn accompanied by sudden cold sweats, dizziness, or loss of consciousness.
Before your visit
- Note when the heartburn started and how often it occurs — for example, whether it happens daily, after meals, at night, or when lying down.
- Track what seems to trigger or worsen the symptom, such as specific foods, beverages, stress, or body position.
- Make a list of any other symptoms you have noticed alongside the heartburn, such as nausea, bloating, cough, or chest tightness.
- Bring a list of all medications and supplements you are currently taking, as some can contribute to acid-related symptoms.
- If you have had any previous stomach or digestive examinations, bring those records or reports if available.
- Be ready to describe how much the symptom affects your daily life, including sleep and eating habits, so the doctor can assess severity.
General principles
Heartburn is a sensation of burning or discomfort that typically originates from the esophagus or stomach, often related to how stomach acid interacts with the lining of the upper digestive tract. Because the symptom overlaps with several possible causes, Internal Medicine (내과) is generally the first specialty to evaluate it, as these physicians are trained to assess the full picture before narrowing down to a specific organ or system.
In the Korean healthcare system, it is generally recommended to visit a local clinic (의원) first rather than going directly to a large hospital, unless the symptom is severe or accompanied by warning signs. If the clinic physician determines that a closer or more specialized evaluation is appropriate, they will typically issue a referral letter (진료의뢰서), which is often required to receive health insurance coverage at a secondary or tertiary hospital.
When a more detailed look at the digestive tract is considered appropriate by the attending physician, examinations of the esophagus and stomach are among the tools that gastroenterologists commonly use. The decision about which examination is suitable, and when, is made by the doctor based on the overall clinical picture — not as a routine step for every patient with heartburn.
Because the chest area is shared by both the digestive and cardiovascular systems, heartburn-like sensations can occasionally prompt evaluation by more than one department. A general internist will usually be the one to decide whether cardiac causes need to be ruled out, making Internal Medicine a practical and efficient first contact for most patients.
FAQ
Should I go to a local clinic (의원) or a hospital (병원) for heartburn?
For most cases of heartburn, a local clinic staffed by an Internal Medicine physician is generally the appropriate first step under the Korean healthcare system. Going directly to a large hospital without a referral is possible but may result in higher out-of-pocket costs and is generally reserved for cases where symptoms are severe or complex.
How is heartburn different from a heart problem, and how will the doctor tell them apart?
Heartburn and cardiac chest discomfort can feel similar, which is why a doctor will ask detailed questions about the character, timing, and associated symptoms before deciding which direction to investigate. The distinction is generally made through clinical assessment by a physician, and if there is any uncertainty, they may involve additional evaluations — this is a decision made by the doctor, not something patients need to determine on their own.
What kind of examinations are generally done for heartburn?
The specific examinations considered depend on the individual patient's history and symptom pattern, and the decision rests with the attending physician. In gastroenterology, it is common for doctors to consider examinations that allow a direct view of the esophagus and stomach lining when symptoms are persistent or unclear, but not every patient with heartburn will need such evaluation.
Is the approach different for children or elderly patients with heartburn?
Children with heartburn-like symptoms are generally seen by Pediatrics (소아청소년과) first, as their digestive systems and symptom presentation can differ from adults. Elderly patients may also have a different symptom profile, and an Internal Medicine physician will take age-related factors and existing health conditions into account when deciding how to proceed — consulting a doctor rather than self-assessing is especially important in these groups.
