Hypothyroidism Treatment in Seomyeon, Busan

What is hypothyroidism?

Hypothyroidism (갑상선 기능 저하증) means the thyroid gland produces too little hormone, slowing many body processes. The most common cause is Hashimoto's thyroiditis, an autoimmune condition. Other causes include previous thyroid surgery, radioactive iodine treatment, certain medicines, and excess or deficient iodine. Mild, or subclinical, hypothyroidism, with raised TSH but normal T4, is common and does not always need treatment.

Symptoms and when to see a doctor

Tiredness, sluggishness and feeling cold
Weight gain, constipation and dry skin
Hair thinning, puffy face, hoarse voice
Low mood, slowed thinking and poor concentration
Heavy or irregular periods, or difficulty conceiving

Symptoms are often gradual and non-specific, so a simple blood test is the best way to check. Severe untreated hypothyroidism with confusion, very low temperature or drowsiness is a rare emergency.

What happens at the clinic

Blood tests: TSH and free T4; thyroid antibodies (anti-TPO) to look for Hashimoto's.
Examination and ultrasound: to check for goitre or nodules when indicated.
Treatment decision: overt hypothyroidism is treated; subclinical cases are treated or monitored depending on TSH level, symptoms, age and pregnancy plans.
Starting levothyroxine: dose based on weight, age and heart health; older adults often start low.
Follow-up: TSH rechecked after about 6–8 weeks and dose adjusted until stable.

Treatment outlook

With the right dose, most people feel well and lead normal lives. Take levothyroxine at the same time daily, typically 30–60 minutes before breakfast or at bedtime on an empty stomach, and separate it by several hours from iron, calcium, antacids and some supplements. Coffee and soy can also reduce absorption. Women planning pregnancy or who become pregnant usually need a dose increase and close monitoring.

Risks and side effects

Levothyroxine is the same as the body's natural hormone, so side effects come mainly from incorrect dosing. Too much can cause palpitations, anxiety, poor sleep, and over time bone loss and atrial fibrillation; too little leaves symptoms unresolved. Regular blood tests prevent both.

Choosing a clinic for hypothyroidism care in Seomyeon

Choose an endocrinologist or internal medicine specialist experienced in thyroid care.
Ask whether thyroid ultrasound is available if a goitre is present.
Bring your current dose and brand, as switching brands may require a recheck.
If pregnant or planning pregnancy, ask for a specific monitoring plan.
Ask for written instructions on taking levothyroxine correctly.

Simple follow-up

Once stable, many patients need only a quick blood test and short visit once or twice a year at a clinic near Seomyeon Station.

How should I take levothyroxine?

Take it at the same time every day on an empty stomach, usually 30 to 60 minutes before breakfast with water. Keep it several hours apart from iron, calcium and antacids, which reduce absorption.

Will I need thyroid medicine for life?

Often yes, especially with Hashimoto's thyroiditis or after thyroid surgery. Some temporary forms, such as after pregnancy or certain types of thyroiditis, may resolve.

Does subclinical hypothyroidism need treatment?

Not always. Treatment depends on the TSH level, symptoms, thyroid antibodies, age and pregnancy plans. Many people with mildly raised TSH are simply monitored.

How long until I feel better on levothyroxine?

Some people notice improvement within a few weeks, but it can take a few months to find the right dose and feel fully well. Blood tests guide adjustments.

Does eating seaweed affect hypothyroidism?

Very high iodine intake, such as large amounts of seaweed or kelp supplements, can worsen thyroid function in some people with Hashimoto's. Normal amounts in a varied diet are usually fine; ask your doctor.
