A form at a Seoul clinic, a row of boxes in Korean, and one space labeled 만성 질환 (mansong jilhwan, chronic conditions). If you have asthma, the word you need is 천식 (cheon-sik). Knowing it before you need it costs about five minutes now. It can save a very stressful five minutes at a registration desk later.
천식: pronunciation and what the word actually contains
천식 is a Sino-Korean compound. 천 (喘) means labored breathing or panting; 식 (息) means breath or rest. Together they describe the condition accurately: the breath that won't come freely. Pronunciation: the first syllable sounds roughly like 'chun' (rhymes with 'fun'), and the second ends with a stopped consonant that doesn't get released the way English 'sick' does. Say 'CHUN-seek' with a soft ending and you're close enough for any Korean listener. The stopped final consonant is one of the patterns that trip up learners most often. Breath has audio for the related vocabulary around 숨 (sum, breath), which appears constantly in medical contexts. In a clinical intake form, the written question is 천식이 있으십니까? (cheon-sik-i isseusimnikka?). At a walk-in clinic, a nurse is more likely to say 천식 있으세요? out loud, dropping the formal ending. Your answer either way: 네, 있어요 (ne, isseoyo), meaning 'yes, I have it.'
At a Korean clinic: registration and first conversation
Korea's healthcare system is accessible in a way that surprises many first-time visitors. Walk-in clinics (의원, uiwon) sit on nearly every block in any city neighborhood. Copays are low. Pharmacies open until 10 p.m. are common. For travelers or short-term residents with asthma, this matters.
The practical sequence goes like this. You walk into a Hospital or a smaller 의원. The front desk asks 어떻게 오셨어요? (eotteoke osyeosseoyo?), meaning 'What brings you in today?' A direct reply works well: 천식 때문에 왔어요 (cheon-sik ttaemune wasseoyo) means 'I came because of asthma.' If your symptoms are active right now, say 숨이 차요 (sum-i chayo), which means you're short of breath. That phrase gets immediate attention at any clinic counter. If you're picking up medication rather than seeking a new consultation, the conversation shifts to the Pharmacy counter. 처방전 있어요 (cheo-bang-jeon isseoyo) means 'I have a prescription.' Pharmacists here are knowledgeable about generic names for common asthma medications, so don't rely on brand names alone.
Vocabulary for respiratory care
A few terms that come up most often in conversations about asthma and respiratory health in Korean:
- 천식 (cheon-sik): asthma
- 흡입기 (heu-bi-gi): inhaler, literally 'inhalation device'
- 기관지 (gi-gwan-ji): bronchial tubes, the airway structure asthma affects
- 알레르기 (al-le-reu-gi): allergy, a loanword used exactly as in English. See Allergy
- 처방전 (cheo-bang-jeon): prescription
- 약국 (yak-guk): pharmacy
- 응급실 (eung-geup-sil): emergency room. See Emergency Room
Most of these follow consistent Sino-Korean syllable patterns. Once you've learned 천식 and 기관지, new medical terms become easier to recognize even when you don't know them yet. The vocabulary builds on itself faster than it looks from the outside.
미세먼지 and 천식: Seoul's year-round respiratory conversation
If you've spent any time in Seoul between October and May, you've seen 미세먼지 (mi-se-meon-ji). Fine dust. Particulate matter blown in from the continent, mixed with local vehicle and industrial emissions. Since the Korean government began issuing daily air quality advisories as public health policy in 2013, 미세먼지 has become embedded in everyday life in a way that has no close parallel in most English-speaking countries.
On heavy 미세먼지 days, elementary school outdoor activities are canceled. Convenience stores sell out of KF94 masks by midmorning. Weather apps display PM2.5 counts alongside temperature, and many people with 천식 check air quality before checking rain probability. Seoul in March can require more planning than Seoul in August. That planning includes knowing your inhaler vocabulary. Know the word for Emergency Room (응급실) before you need it. Know that Korean pharmacies carry major asthma medications under generic names. Bring documentation of your existing prescription in international format rather than just a brand name. The pharmacist can usually match a generic name immediately. The phrase 천식 약 처방전이 필요해요 (cheon-sik yak cheo-bang-jeon-i piryohaeyo, 'I need a prescription for asthma medication') sets up a clinic visit clearly.
Explaining your condition in everyday Korean
Beyond the clinic, you might need to tell a Korean host, a hiking guide, or a language school coordinator about your asthma. The most direct sentence: 저는 천식이 있어요 (jeo-neun cheon-sik-i isseoyo), meaning 'I have asthma.' Natural, clear, and immediately understood. To mention that you carry an inhaler: 저는 흡입기를 가지고 다녀요 (jeo-neun heu-bi-gi-reul gajigo danyeoyo), meaning 'I carry an inhaler with me.' You're not oversharing. You're giving someone the information they'd need to help you if something happened. I tell my language students the same thing I'll tell you here: medical vocabulary isn't advanced Korean. It's practical Korean. Learning it early reflects real-world priorities, not textbook ones. For broader health-related vocabulary in Korean, Wellness culture covers wellness culture and everyday health language, and Health checkup walks through the vocabulary for the regular checkup system (건강검진) that Koreans use throughout their lives.
Common questions
Q: Is 천식 the only Korean word for asthma?
천식 is the standard clinical and everyday term. It's what you write on a medical form and what a Korean doctor says in conversation. In older texts or traditional medicine contexts (한방, hanbang), you might occasionally see 천명 (cheonmyeong), which refers specifically to the wheezing sound that accompanies an asthma attack rather than the condition itself. Don't let that variation slow you down. In any modern Korean clinic, pharmacy, or conversation, 천식 is the word everyone uses and recognizes instantly. If a doctor says 기관지 천식 (gi-gwan-ji cheon-sik), they're specifying the bronchial form. It's still 천식. The Doctor vocabulary page covers the clinical vocabulary you'd need alongside 천식 during a full consultation.
Q: Can I refill my asthma prescription at a Korean pharmacy?
Yes, in most cases. Korean pharmacies (약국) carry a wide range of asthma medications under generic names. Common inhalers like salbutamol and beclomethasone-based inhalers are available. You'll need a Korean prescription first, which means a brief clinic visit. That visit is usually fast and affordable even if you're paying out of pocket as a visitor. Bring documentation of your existing prescription if you have it. Saying 천식 약 처방전이 필요해요 at the clinic sets up the conversation quickly. The Pharmacy page has the counter vocabulary you'll need once you're standing at the 약국 window with prescription in hand.
Q: Is asthma common or well understood in Korean medical culture?
Yes. Awareness has increased significantly over the past decade, driven partly by 미세먼지 coverage that made air quality a household conversation starting around 2013. Korean childhood asthma rates have been tracked in medical literature since the 1990s, with urban areas like Seoul showing higher rates than rural regions. The government runs public awareness campaigns through regional health centers, and most Korean adults know what 천식 means. Saying 저는 천식이 있어요 to a Korean host or coworker isn't unusual or uncomfortable. It's as ordinary as saying 저는 안경을 써요, meaning 'I wear glasses.' Koreans won't dramatize it. They'll probably ask if you need a quieter room away from cooking smoke, or check whether your schedule allows for a rest day during a heavy 미세먼지 week.
천식 is two syllables
천식 is two syllables. It doesn't take long to learn. If you're traveling to Korea with asthma, that word and the phrase 숨이 차요 (I'm short of breath) are the two things most worth memorizing before you board. The Koko AI app organizes Korean vocabulary by real-life context: clinic visits, daily conversations, health and wellness. Medical Korean doesn't have to exist in a separate category from everything else you're already building. Start with 천식. The rest layers in naturally, one word at a time.
