Short answer

Pediatrics(소아청소년과) is generally the first department to see when you are concerned about a child's height or growth. If a hormonal or metabolic cause is suspected, the pediatrician will typically refer the child to Pediatric Endocrinology(소아내분비과) for further evaluation.

Which department

  1. 1Pediatrics (소아청소년과)
    Pediatricians are trained to monitor children's overall growth and development, including height and weight tracking against standardized growth charts. They assess whether a child's growth pattern falls within the expected range for their age and sex, and coordinate further workup if needed. — First / second line: This is generally the right first stop — a pediatric clinic (의원) level visit is appropriate in most cases. If the pediatrician identifies signs suggesting a hormonal or systemic cause, they will typically issue a referral to a higher-level specialist.
  2. 2Pediatric Endocrinology (소아내분비과)
    This subspecialty focuses on hormone-related conditions in children, including growth hormone concerns, thyroid issues, and other endocrine factors that can affect growth. Pediatric endocrinologists use specialized assessments to evaluate whether a child's growth pattern may have an underlying hormonal basis. — First / second line: Children are usually referred here by a general pediatrician rather than visiting directly. In Korea, a referral letter (요양급여의뢰서) is required to access a subspecialty clinic at a tertiary or university hospital with full national health insurance coverage.
  3. 3Korean Medicine Clinic — Hanuiwon (한의원)
    Some families in Korea consult a Korean medicine practitioner regarding a child's constitution and general health management. Korean medicine practitioners assess overall physical balance and vitality within their own diagnostic framework, though growth evaluation in the conventional medical sense — such as bone age assessment or hormone level testing — is outside the scope of Korean medicine. — First / second line: A Korean medicine clinic can be visited directly without a referral. It is worth keeping in mind that this setting does not replace conventional growth assessment; families often use it alongside, not instead of, a standard pediatric evaluation.

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 suddenly loses consciousness or cannot be roused — go to the emergency room or call 119 immediately.
  • The child shows signs of severe difficulty breathing or respiratory distress.
  • The child experiences a sudden, unexplained seizure for the first time.
  • The child develops rapidly progressing weakness, paralysis, or loss of vision in a short period.
  • The child shows signs of anaphylaxis — severe swelling of the face or throat, hives spreading rapidly, or inability to breathe — after taking any substance.

Before your visit

  • Note the child's current height and weight, and bring any previous growth records or health check-up booklets (아이 건강수첩) if available.
  • Recall approximately when you first noticed the growth concern — whether it has been gradual over months or years, or whether it seemed to accelerate or stall recently.
  • Note the heights of both parents and any siblings, as family height patterns are typically relevant information for the doctor.
  • List any chronic conditions the child has been diagnosed with, and bring a record of any medications or supplements the child is currently taking.
  • Note whether the child has shown any other changes alongside growth concerns, such as changes in weight, energy level, appetite, or development of secondary sexual characteristics.
  • If the child has had any prior blood tests, imaging, or bone age X-rays related to growth, bring those results or reports to the appointment.

General principles

In general medical practice, a child's growth is assessed by comparing their height and weight measurements over time against standardized growth charts. A child who consistently follows a growth curve — even at the lower end — may be evaluated differently from one whose growth appears to have slowed or plateaued unexpectedly. The pattern and trend over time, rather than a single measurement, tends to be the key point of interest for clinicians.

When a pediatrician decides that further investigation is warranted, the evaluation may involve looking at factors such as bone maturation, nutritional status, and hormone levels. These assessments help identify whether a child's growth pattern reflects normal familial variation, nutritional factors, or a condition that may benefit from medical attention. The specific direction of investigation is determined by the doctor based on the individual child's situation.

In Korea's general healthcare flow, a pediatric clinic (소아청소년과 의원) is typically the appropriate starting point for growth concerns. If the child is referred to a subspecialty at a tertiary hospital (상급종합병원), a referral letter (요양급여의뢰서) is required to receive national health insurance coverage at that level; secondary hospitals (병원·종합병원) can generally be visited directly without a referral under normal insurance coverage. It is advisable not to delay seeking evaluation if a growth concern has been noticeable over an extended period.

FAQ

Should I go to a local pediatric clinic or directly to a university hospital for my child's growth concern?

In most cases, starting at a local pediatric clinic (의원) is the recommended approach under Korea's general healthcare system. If the pediatrician determines that specialist evaluation is needed, they can issue a referral to a higher-level institution. Visiting a tertiary or university hospital directly without a referral is possible, but a referral letter (요양급여의뢰서) is required to receive full national health insurance coverage at tertiary hospitals (상급종합병원).

How is a child's growth concern evaluated differently from an adult height concern?

Children's growth evaluation typically focuses on the growth trajectory over time — meaning how fast or slowly the child is growing relative to their own previous measurements and expected growth curves for their age group. Because children's bones are still developing, tools such as bone age assessment can provide additional context that is not relevant for adults. A pediatrician or pediatric endocrinologist is the appropriate person to interpret these factors for a child.

At what point is it generally considered worth seeing a doctor about a child's height?

General medical guidance suggests that it is worth seeking a pediatric evaluation if the child appears to be growing significantly more slowly than peers of the same age and sex, if growth seems to have stalled over a period of months, or if the parents have a specific concern they would like assessed. Early evaluation is generally better than waiting, as some factors that influence growth are more readily addressed at younger ages. A doctor's assessment is the only way to determine whether there is anything worth following up on.

Can a Korean medicine practitioner (한의원) evaluate my child's growth?

Korean medicine practitioners assess a child's constitution and general health within their own diagnostic framework, which differs from conventional growth evaluation methods such as growth charts, bone age X-rays, or hormone testing. If your primary concern is whether your child's height falls within a medically expected range or whether there is an underlying cause to investigate, a conventional pediatric evaluation is generally the appropriate setting for that assessment. Some families choose to visit both types of practitioners for different aspects of their child's health.
