Short answer

Pediatrics(소아청소년과) is generally the first department to visit when a child has a stomachache, as pediatric specialists are trained to evaluate abdominal symptoms across all age groups. Depending on the findings, the pediatrician may refer the child to Pediatric Surgery(소아외과) or Pediatric Gastroenterology(소아소화기영양과) for further evaluation.

Which department

  1. 1Pediatrics (소아청소년과)
    Pediatricians are the primary specialists for children's health and are trained to assess a wide range of causes of abdominal pain in children, including infections, constipation, functional disorders, and systemic illness. They can perform an initial physical examination and determine whether the symptom requires further specialist involvement. — First / second line: In general, a local pediatric clinic (의원) is the appropriate first stop for a child with stomach pain that is not severe or accompanied by alarming signs. If the clinic-level doctor finds signs suggesting a more serious condition, a referral letter (진료의뢰서) may be issued for a secondary or tertiary hospital.
  2. 2Pediatric Surgery (소아외과)
    Pediatric surgeons handle abdominal conditions in children that may have a surgical cause, such as appendicitis, intestinal obstruction, or hernia. They are typically involved after an initial evaluation by a pediatrician suggests a possible surgical issue. — First / second line: This department is generally accessed via referral from Pediatrics rather than as a first visit. In an emergency setting, the emergency department team will typically coordinate surgical consultation directly.
  3. 3Pediatric Gastroenterology (소아소화기영양과)
    This subspecialty focuses on digestive tract conditions in children, including chronic abdominal pain, inflammatory bowel conditions, and nutritional issues. It is typically involved when symptoms are recurring, chronic, or suggest a specific gastrointestinal cause. — First / second line: Generally reached through referral from a general Pediatrics clinic or hospital department. A referral letter is commonly required when visiting a secondary or higher-level hospital in Korea's healthcare system.
  4. 4Emergency Medicine (응급의학과)
    When a child's abdominal pain is sudden, severe, or accompanied by red-flag symptoms, the emergency department is the appropriate place regardless of which specialist would normally manage the condition. Emergency physicians coordinate with relevant specialists on-site. — First / second line: Go directly to the emergency room (응급실) or call 119 without waiting for a regular clinic appointment if any of the red-flag signs described below are present.

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).

  • The child has sudden, severe abdominal pain that is getting rapidly worse and cannot be relieved by any position.
  • The abdomen appears visibly distended or feels board-hard to the touch.
  • The child is vomiting repeatedly, especially if the vomit is green or contains blood.
  • There is blood in the stool, or the stool is black and tar-like.
  • The child shows signs of severe distress such as inability to walk, loss of consciousness, or extreme paleness.

Before your visit

  • Note exactly when the pain started, how long it has lasted, and whether it is constant or comes and goes.
  • Observe and describe the location of the pain — for example, around the belly button, lower right side, or all over — and whether it shifts.
  • Track any accompanying symptoms such as fever, vomiting, diarrhea, loss of appetite, or recent changes in bowel habits.
  • Bring a list of any medications, supplements, or herbal remedies the child is currently taking.
  • Recall whether the child has had similar episodes before, and if so, bring any previous test results or medical records.
  • Note whether the child has recently traveled, changed diet, or been in contact with someone who was ill.

General principles

Abdominal pain in children has a very broad range of possible causes, which is why Pediatrics(소아청소년과) acts as the general entry point in Korea's healthcare system. A pediatrician is trained to differentiate between common causes such as constipation or viral gastroenteritis and less common but more serious conditions, using clinical examination and, when appropriate, further testing as guided by medical judgment.

In Korea's healthcare system, it is generally recommended to start at a local clinic (의원) level before moving to a larger hospital. If the local pediatrician determines that specialist imaging, endoscopy, or surgical evaluation is needed, they will typically issue a referral letter (진료의뢰서), which is often required to access secondary or tertiary hospitals under the national health insurance (건강보험) system.

Children's abdominal symptoms can sometimes be linked to causes outside the digestive system, such as urinary tract issues, musculoskeletal causes, or stress-related functional pain. This is one reason why the initial comprehensive assessment by a pediatrician — rather than going directly to a subspecialty — is generally considered the most practical first step.

The diagnostic approach for childhood stomachache typically follows a step-by-step process guided by symptom history, physical examination, and the child's age, all of which a doctor will assess during the consultation. Parents are encouraged to share as much detail as possible about the timing, character, and associated symptoms to help the doctor form a complete clinical picture.

FAQ

Should I go to a local pediatric clinic or a hospital emergency room for my child's stomachache?

In general, a local pediatric clinic (의원) is appropriate for stomachaches that are mild to moderate and not accompanied by red-flag symptoms. If the pain is severe, sudden, or accompanied by alarming signs such as those listed above, going directly to an emergency room or calling 119 is the safer option. A doctor can then advise on next steps.

How is childhood stomachache different from adult stomachache in terms of which department to visit?

For children, Pediatrics(소아청소년과) is generally the first department because pediatricians are specifically trained to assess symptoms in the context of a child's developmental stage, which can significantly affect how conditions present. Adults would typically start at Internal Medicine(내과) or General Surgery(외과) depending on the nature of the pain, but these departments are generally not the first choice for children.

What kinds of tests are generally done when a child has a stomachache?

The type of testing, if any, is determined entirely by the doctor based on the clinical examination and symptom history — this cannot be decided before the visit. In general medical practice, doctors may consider blood tests, urine tests, or imaging depending on what they find during the physical examination. No specific test should be expected or requested without a doctor's assessment first.

My child's stomachache keeps coming back over several weeks — does that change which department I should visit?

Recurring or chronic abdominal pain in a child is still generally evaluated first by Pediatrics(소아청소년과), who can assess the pattern and decide whether a subspecialty referral — such as to Pediatric Gastroenterology(소아소화기영양과) — is appropriate. Bringing a detailed record of when episodes occur, how long they last, and what other symptoms accompany them will be very helpful for the doctor's assessment.
