Korea Growth Clinic for Kids: What to Expect & How to Choose

Key takeaways

• A growth evaluation looks at growth history, parents' heights, puberty stage, bone age and blood tests.
• Most short children are healthy and growing normally. Growth hormone is meant for clearly defined conditions.
• In the US, the Pediatric Endocrine Society calls growth hormone for idiopathic short stature a controversial indication, and it advises a cautious approach.
• Korea's growth clinic market is booming, and so are exaggerated ads. Watch for guarantees and pressure.
• Treatment is long-term and needs regular monitoring, which is hard to do on a short trip.
• Prices vary by clinic and by treatment plan, so ask about the total cost over time, not only the first visit.

What is a growth clinic in Korea?

A "growth clinic" (seongjang clinic) is a children's clinic that tracks height and growth, checks for growth disorders and early or late puberty, and advises parents on next steps. Some are part of hospital pediatric endocrinology departments. Others are private clinics, and some also offer Korean medicine programs.

Growth clinics have become very popular. The Korea JoongAng Daily reported in January 2026 that clinics in affluent areas such as Gangnam are booming, that parents describe growth tests as "essential," and that one prominent clinic had a wait of more than a month for a growth test. Parents often feel pressure from marketing about a "golden time" for growth.

Why do some foreign families look at Korea?

Some families want a second opinion or a detailed evaluation, and some say they have struggled to find a doctor at home who will take their concerns seriously. In a 2023 JoongAng Daily report, an Australian mother said she found it very difficult to find a doctor in Australia to prescribe growth hormone for her children's idiopathic short stature.

That is a reason families look abroad. It is not proof that treatment is right for every child. Whether a child needs treatment is a medical decision that should come from a careful evaluation.

What does a proper growth evaluation include?

A thorough evaluation usually includes:

1. Growth history: Past height and weight measurements, plotted on a growth chart. Bring records from your pediatrician if you have them.
2. Family heights: The heights of both parents help estimate a child's expected adult height.
3. Physical exam: Including puberty stage and a check for signs of other health conditions.
4. Bone age X-ray: An X-ray, usually of the hand and wrist, shows how mature the bones are compared with the child's actual age.
5. Blood tests: To look for causes such as thyroid problems or other conditions. Some children need additional hormone tests.
6. A conversation about results: The doctor should explain what the numbers mean, in plain language, and whether treatment is needed.

How to understand bone age

Bone age is a tool, not a verdict. The Korea Times has reported that bone age is typically within about 12 months of the child's actual age. When bone age is much further ahead, the doctor may look for early puberty. When it lags by two years or more, the doctor may investigate possible growth hormone deficiency. The doctor interprets these numbers together with growth speed, puberty stage and family height, so one result alone should never decide a treatment.

Who actually needs growth hormone?

Growth hormone is a prescription medicine. It is clearly indicated for conditions such as growth hormone deficiency and Turner syndrome. As Seoul St. Mary's Hospital pediatrics professor Suh Byung-kyu told the JoongAng Daily, it is not right to recommend injections to a large number of children, and injections may not have a large effect if a child is already growing well.

For children who are short without an identified medical cause, which is called idiopathic short stature, the picture is more complicated. The US FDA approved growth hormone for this group in 2003, but the Pediatric Endocrine Society's guidelines describe it as a controversial indication and recommend a conservative approach. The Society notes that, for these children, treatment is solely about height, the height gain varies, and little is known about long-term risks. It recommends that pediatric endocrinologists manage evaluation and treatment.

What are the risks?

Growth hormone usually means regular injections for years. Like any medicine, it can cause side effects. According to the Ministry of Food and Drug Safety data cited by the JoongAng Daily, reports of serious adverse reactions linked to growth hormone injections rose from 9 in 2020 to 165 in 2024, as prescriptions climbed. Korean authorities have inspected clinics for exaggerated advertising and say they plan to tighten safety management for growth hormone products.

These numbers don't mean treatment is unsafe when it's prescribed for the right reasons. They are a reason to insist on a proper diagnosis, ongoing monitoring and honest answers about benefits and risks.

Red flags to watch for

• Promises such as "10 cm taller" or guaranteed results
• Pressure to start injections at the first visit
• Packages in which injections are mandatory for every child
• No bone age test or blood tests before treatment is recommended
• No pediatric endocrinologist involved
• "Golden time" or "you're already late" messaging
• Supplements, foods or posture programs advertised with specific centimeter gains
• Unwillingness to explain evidence, risks and alternatives

Some clinics also offer Korean medicine growth programs, herbal products or posture management. Evidence that these increase adult height is limited, so ask what it is based on.

Can a short trip work?

For an evaluation, often yes. You can arrange a consultation, tests and a discussion of results during a trip, though popular clinics may have long waits, so book early.

For treatment, it is harder. Growth hormone needs regular monitoring by a pediatric endocrinologist, and a plan for supply and follow-up. Before you begin anything in Korea, ask how treatment would continue at home. Rules for bringing prescription injectables across borders are strict. The FDA says importing drugs for personal use is illegal in most circumstances, so ask the clinic and your own doctor before you plan to carry medicine home.

A practical approach is to bring your child's growth records, get a clear evaluation, request the results and images in English, and review them with your own pediatrician or pediatric endocrinologist.

Height is one part of a child's health. Whatever you decide, try to keep conversations at home supportive. Children can feel pressure when adults talk about their height.

How to choose a safe growth clinic

• Credentials: Ask who will evaluate your child and whether a pediatric endocrinologist is involved.
• A full evaluation first: Treatment recommendations should follow tests, not precede them.
• A clear explanation: The doctor should explain the diagnosis, the evidence, the risks and the alternatives, including watchful waiting.
• English communication: Ask for an interpreter and for results in English.
• No pressure: A good clinic lets you take time and get a second opinion.
• A follow-up plan: Ask what monitoring is needed, how often, and who will do it.

What about price?

Prices vary by clinic, by the tests included and by the treatment plan, so we don't quote numbers here. Ask for an itemized written quote for the evaluation. If treatment is recommended, ask for the total estimated cost over the full course, including the medicine, monitoring visits and any tests, not only the first visit.

Questions to ask before you book

1. Who will evaluate my child, and what is their specialty?
2. Which tests are included, and why are they needed?
3. What does my child's bone age tell us?
4. Does my child meet the criteria for any treatment? What are the alternatives?
5. What are the expected benefits, and what are the risks and side effects?
6. How long would treatment last, and how often is follow-up needed?
7. How would treatment continue if we live abroad?
8. Can I get the results and images in English to share with my own doctor?

FAQ

What happens at a growth clinic in Korea?

The doctor reviews your child's growth history and family heights, examines your child and usually orders a bone age X-ray and blood tests. Some children need further hormone tests. The doctor then explains whether growth looks normal, needs monitoring or may benefit from treatment.

Do all short children need growth hormone?

No. Many short children are healthy and growing normally. Growth hormone is meant for clearly defined conditions, and for otherwise healthy short children the benefits and risks need careful discussion with a pediatric endocrinologist.

What is a bone age test?

A bone age test is a low-dose X-ray, usually of the hand and wrist, that shows how mature a child's bones are compared with their actual age. Doctors use it, together with growth speed, puberty stage and family height, to estimate how much growing a child may have left.

Can I start growth hormone in Korea and continue it at home?

Growth hormone is a prescription medicine that needs ongoing monitoring by a pediatric endocrinologist. Starting treatment on a short trip is rarely practical, and rules for bringing injections across borders are strict. Ask the clinic and your own doctor how treatment, supply and follow-up would work before you begin.

How can I spot an unsafe growth clinic?

Be cautious about guaranteed height gains, pressure to start injections immediately, mandatory injection packages, no testing before treatment and vague answers about risks. A safe clinic explains the diagnosis, the evidence and the alternatives, and gives you time to decide.
