Thyroid specialist at Apgujeong Hana Clinic.
The thyroid gland — a small butterfly-shaped gland in the front of the neck — controls your body's metabolism, energy production, heart rate, body temperature, mood and much more. When it functions abnormally, the effects are wide-ranging and often mistaken for stress, ageing or lifestyle factors. Thyroid disorders are among the most commonly missed diagnoses in adults — particularly women.
Apgujeong Hana Clinic's thyroid clinic is led by Dr. Shin Hyun-won — a board-certified endocrinologist trained at Samsung Seoul Hospital with a Medical PhD from Sungkyunkwan University and over 20 years of specialist experience. Dr. Shin evaluates and treats all thyroid conditions in English, from simple TSH abnormalities to complex autoimmune thyroid disease and thyroid nodule management.
For expats in Seoul, thyroid conditions are particularly important to manage correctly. Continuation of thyroxine (levothyroxine) therapy, access to full thyroid antibody panels and thyroid ultrasound — all with English results — are available at our Apgujeong clinic without the complexity of navigating a large Korean hospital system.

How to tell if your thyroid may not be working correctly.
Thyroid disorders are called "great mimics" in medicine because their symptoms overlap with so many other common conditions — stress, depression, ageing, menopause and chronic fatigue. This is why thyroid disorders are frequently missed or misattributed for years. A simple blood test is the only reliable way to diagnose a thyroid problem.
What your thyroid blood tests actually measure.
A single TSH test — as used in many routine checkups — can miss important thyroid abnormalities, particularly early autoimmune thyroid disease. At Apgujeong Hana Clinic, we offer the complete thyroid panel to ensure no aspect of your thyroid health is overlooked.
| Test | What It Measures | Why It Matters |
|---|---|---|
| TSH | Thyroid stimulating hormone from the pituitary | The most sensitive marker of thyroid function — elevated in hypothyroidism, low in hyperthyroidism |
| Free T4 | Active thyroxine — the primary thyroid hormone | Measures actual circulating thyroid hormone — confirms severity of hypo or hyperthyroidism |
| Free T3 | Triiodothyronine — the most biologically active form | Important for patients on T4 therapy who remain symptomatic despite normal TSH |
| Anti-TPO | Thyroid peroxidase antibodies | Positive in Hashimoto's and Graves' disease — confirms autoimmune thyroid disease |
| Anti-TG | Thyroglobulin antibodies | Additional autoimmune marker — important in thyroid cancer monitoring |
| Thyroglobulin | Protein produced by thyroid cells | Used in thyroid cancer surveillance — should be undetectable after thyroid removal |
How we treat thyroid conditions at Apgujeong Hana Clinic.
Thyroid treatment is highly individualised. The appropriate approach depends on whether the thyroid is underactive or overactive, the severity of the dysfunction, the underlying cause and the patient's overall health and symptoms. Your specialist will explain all options clearly in English.
