Period Problems in Korea: When Should You Visit an OB-GYN?

October 5, 2026

Irregular, painful, heavy or absent periods — a guide to getting help

Quick answer: See an OB-GYN in Korea if your periods are irregular for several months, so heavy you change protection every 1–2 hours, painful enough to disrupt daily life, absent for three months, or if you bleed between periods or after sex. Most period problems can be diagnosed with ultrasound and blood tests.

Periods can be affected by many things — stress, travel, new routines and changes in diet are all common when living abroad. Some period changes are temporary, but others deserve a medical check. Here's a guide to knowing when to visit an OB-GYN in Korea.

Irregular Periods

See a doctor if your cycles are regularly shorter than 21 days or longer than 35 days, or vary a lot month to month. Possible causes include PCOS, thyroid problems and hormonal changes.

Heavy Periods

Soaking through a pad or tampon every hour or two, passing large clots or bleeding for more than seven days can be signs of fibroids, polyps or hormonal issues — and can lead to anemia.

Painful Periods

Pain that stops you from working or studying, isn't relieved by painkillers or is getting worse over time may be a sign of endometriosis or adenomyosis.

Missed or Absent Periods

After ruling out pregnancy, missing three or more periods should be checked.

Bleeding Between Periods or After Sex

This should always be evaluated, especially if it persists.

Severe PMS

If mood changes before your period affect your relationships or work, treatment options are available.

What to Expect at the Clinic

  • Questions about your cycle history — a period-tracking app helps
  • Pregnancy test
  • Pelvic exam and ultrasound
  • Blood tests for hormones, thyroid and anemia

Treatment Options

Depending on the cause: pain relief, hormonal treatments, iron supplements, treatment for conditions like PCOS or fibroids, or lifestyle support.

Care in English

Period problems are personal. Discussing them with an English-speaking OB-GYN makes it easier to describe your symptoms accurately and understand your options.
