Overview

Hyperthyroidism can make your body feel stuck in high speed.

Hyperthyroidism happens when the thyroid gland produces too much thyroid hormone. This can affect the heart, weight, sleep, mood, digestion and menstrual cycle.

At Apgujeong Hana Clinic, we evaluate thyroid symptoms, review blood tests and help identify whether the cause may be Graves’ disease, thyroiditis, nodules or medication-related.

Diagnosis Pathway

We confirm thyroid overactivity with targeted testing.

Symptoms alone are not enough. Blood tests help confirm whether thyroid hormone is high and whether more testing is needed to find the cause.

TSH
Thyroid-Stimulating Hormone Often the first screening test. Low TSH can suggest overactive thyroid activity.
T4
Free T4 Measures one of the main thyroid hormones and helps judge severity.
T3
T3 Testing Useful when hyperthyroidism is suspected but T4 is not clearly high.
Ab
Thyroid Antibodies May help identify autoimmune causes such as Graves’ disease.
Treatment Planning

Treatment depends on the cause, severity and risk.

Hyperthyroidism treatment is individualized. Your doctor reviews symptoms, lab results, heart rate, pregnancy status, medication history and possible cause before planning care.

Symptom Control
Heart-racing, tremor and anxiety symptoms may need short-term control while thyroid testing is reviewed.
Fast Relief
Antithyroid Medicine
Medicines may reduce thyroid hormone production when suitable for the patient and diagnosis.
Common Option
Cause Review
Graves’ disease, thyroiditis and thyroid nodules require different follow-up plans.
