Learn Thai Vocabulary for the Doctor and Hospital

Published September 12, 2026 · 8 min read · Thai Language

Thai hospitals are excellent and the paperwork is fast — but the counter you need is labelled in Thai, and “my stomach hurts” is not a sentence you want to be improvising at seven in the morning.

This is the one chapter of Thai that people put off and then need at short notice. If you learn Thai vocabulary for the doctor and hospital while you are perfectly healthy, the whole visit changes: you walk in, read the department signs in Thai script instead of hunting for an English one, tell the nurse in one clean sentence where it hurts and how long it has been going on, and understand the words called out at the pharmacy window. This Thai language guide gives you the signs, the sentence patterns, the body parts and the symptom words — in Thai script, in plain Thai transliteration and in literal English, so you can see how each phrase is actually built.

Why hospital Thai is different from restaurant Thai

Ordering food is forgiving. You can point, you can smile, and the worst outcome is the wrong noodles. A clinic is the opposite: the person in front of you is making decisions based on what you say, and the vocabulary is narrow and specific. The good news is that this is a small, closed set: you can learn Thai vocabulary for an entire clinic visit in an evening, because “narrow and specific” also means short. Around forty words cover a routine visit, and they recombine endlessly — once you know ปวด (puat, “to ache”) and a handful of body parts, you can build a dozen complaints without learning a single new verb.

Two practical notes before the vocabulary. Private hospitals in Bangkok, Chiang Mai and Phuket usually have English-speaking staff at the front desk, but the further you get from the reception counter — and the further you get from a tourist city — the more Thai you need. And in a real emergency the number to dial is 1669 for an ambulance, with 1155 for the Tourist Police, who answer in English and will translate.

Read Thai script on the hospital signs first

Thai hospital signage is wonderfully consistent. The same dozen words appear on the same dozen doors nationwide, which makes them ideal practice if you are still learning to read Thai script — you already know what the sign must say, so you are only decoding the letters.

Notice how many of these are compounds of words you may already have: ห้อง (hong, room) plus something, or ผู้ (phu, person who) plus something. Thai builds new vocabulary by stacking plain words rather than importing Latin roots, which is a real gift to the beginner. If the letters are still slow, ten minutes a day with the flashcard trainer will get you reading these signs faster than any phrasebook can.

The two words at the front counter

You will be asked whether you have been before. เคยมาไหมครับ (khoey maa mai khrap) — literally “ever come, yes-no?”. Answer เคย (khoey, “have before”) or ไม่เคย (mai khoey, “never”). If you have no appointment, say ไม่ได้นัดครับ (mai dai nat khrap) — “didn’t book”. Walk-ins are completely normal in Thailand.

ปวด or เจ็บ: the distinction that matters

English says “it hurts” for everything. Thai splits the idea in two, and using the wrong one is the single most common mistake learners make in a clinic.

• ปวด (puat, low tone) — a dull, internal, ongoing ache. Headache, stomach ache, toothache, period pain, sore muscles.
• เจ็บ (jep, low tone) — a sharp, surface or injury pain. A cut, a burn, a sore throat, something that hurts when touched or moved.

So a headache is ปวดหัว (puat hua), never เจ็บหัว; but a sore throat is เจ็บคอ (jep kho), never ปวดคอ — which would mean a stiff, aching neck instead. The sentence pattern could not be simpler:

ปวด + [body part] + ครับ/ค่ะ

Thai drops the pronoun and the verb “to have” entirely. ปวดท้องค่ะ is a complete, natural, polite sentence meaning “I have a stomach ache.” Add นิดหน่อย (nit noi, a little) or มาก (mak, a lot) on the end to grade it, and สามวันแล้ว (saam wan laeo, “three days already”) to say how long.

Thai body-part words worth memorising

• หัว hua — head
• ท้อง thong — stomach, belly
• คอ kho — throat and neck (one word for both)
• หลัง lang — back
• ฟัน fan — tooth
• หู hu — ear
• ตา taa — eye
• อก ok — chest
• แขน khaen — arm
• ขา khaa — leg

These are one-syllable, high-frequency words — exactly the sort of material a beginner Thai lesson should be built on, because each one is also a reading drill in Thai consonants and vowels. หัว, หลัง and หู all show the silent leading ห that pushes a low-class consonant up into the rising tone; the tone marks guide explains why that little ห is there at all.

Thai symptom words you can say in one breath

Learn these ten and you have covered most of what a Thai doctor will ask about. ไม่สบาย is the all-purpose opener. If you remember nothing else, ไม่สบายครับ plus pointing at the part that hurts will get you seen.

At the pharmacy window

Thai medicine words are built on one root: ยา (yaa), medicine. ยาแก้ปวด (yaa kae puat) is literally “medicine that fixes ache” — a painkiller. ยาลดไข้ (yaa lot khai) is “medicine that lowers fever”. ยาแก้แพ้ (yaa kae phae) is an antihistamine. The verb for taking medicine is กินยา (kin yaa) — literally “eat medicine” — and the instruction you will hear most is กินหลังอาหาร (kin lang aahaan), “take after food”. Our separate guide to Thai pharmacy vocabulary goes further into dosages and the green-cross shop signs.

Two more words for the cashier: ใบเสร็จ (bai set, receipt) and ใบรับรองแพทย์ (bai rap-rong phaet, medical certificate). Ask for both if you intend to claim on insurance, ประกัน (pra-kan).

Thai pronunciation traps in this vocabulary

• ไข้ and ไข่. One tone mark apart. ไข้ (falling tone) is fever; ไข่ (low tone) is egg. Saying you “have an egg” is a classic, and the reason Thai transliteration alone will never be enough.
• ยา and หญ้า. Yaa with a mid tone is medicine; yaa with a falling tone is grass.
• หมอ is not แพทย์. Both mean doctor. หมอ (mor, rising tone) is the everyday word and what you will actually say; แพทย์ (phaet) is the formal term you will see written on doors and certificates.
• Keep the particle on. In a clinic you are speaking to strangers who are senior in the room, so every sentence ends in ครับ (men) or ค่ะ (women). Dropping it sounds curt at exactly the moment you want to sound cooperative.

A study tip: build the sentence before you need it

Write out one sentence tonight and keep it in your phone: your name, your allergies (แพ้ยา…), any regular medication, and your blood type. Have a Thai friend or a colleague check it once. That single note does more for you at a hospital counter than a hundred half-learned words, and copying it out by hand is a painless way to learn the Thai alphabet in context.

Then drill the pattern rather than the list. Say ปวด plus a different body part ten times a day for a week, and the structure becomes automatic — which is the whole point, because the day you need it is the day you will not be in the mood to conjugate anything. It is a small piece of Thailand expat language competence, and one of the very few that you will be glad to have long before you use it. Of all the places to learn Thai vocabulary, this is the one worth doing early — and the alphabet reference is where the reading half of it starts.

This guide is language study material, not medical advice. For symptoms that worry you, see a doctor — and in an emergency, dial 1669.
