Gastroenterology in Thailand (2026): Endoscopy Costs, Bowel Prep and What's Actually Included

A gastroscopy in Bangkok runs from about 19,000 baht, a colonoscopy from 29,000, and the combined procedure from 39,000 — but biopsy and deep sedation are usually billed separately. Wellmap's verified option in Thailand is Phyathai 2 Hospital, a full-service international hospital.

A gastroscopy and colonoscopy together in Bangkok are commonly quoted at $1,000-1,100, against individual hospital prices of roughly $500-900 for colonoscopy alone — but the number on the package page is rarely the number you pay, because biopsy and deep sedation are usually separate.

What It Costs

Procedure	Published price
Gastroscopy alone	From 19,000 baht (~$600)
Colonoscopy alone	15,900-29,000 baht (~$500-900)
Combined gastroscopy + colonoscopy	24,900-39,400 baht (~$1,000-1,100)

Figures above come from specific Bangkok hospital package pages, which vary by facility — a general-hospital endoscopy suite and a premium digestive-care centre quote differently for what is clinically the same procedure.

What’s In the Price, and What Isn’t

Published packages typically include: the specialist’s fee, the endoscopy suite, bowel-preparation medication with nurse supervision, moderate sedation, and recovery suite time.

Usually billed separately:

Biopsy and histopathology — one hospital states this plainly: a polyp found and sampled during the procedure is an added charge, not part of the headline price
Deep sedation by an anaesthesiologist — the standard package includes moderate sedation only; if your case needs deeper sedation, that’s extra

What this means in practice: ask for the all-in price assuming a biopsy is taken, not the price assuming it isn’t. Polyps are common enough that “no biopsy” shouldn’t be your planning assumption.

Preparing for a Colonoscopy in Thailand

An oral laxative starting the evening before
A clear-liquid diet for the 24 hours beforehand
6 hours with nothing to eat or drink immediately before the procedure
Anticoagulants — if you’re on blood thinners, tell the clinic when you book; stopping them typically needs 3-7 days’ lead time on your doctor’s instruction

Who This Suits, and Who It Doesn’t

A routine screening colonoscopy with no expected complex findings is a reasonable case for combining with travel — the price gap against many home-country costs can cover the flight several times over.

It suits you less well if a biopsy result might need urgent local follow-up with a gastroenterologist who already knows your history, or if you have inflammatory bowel disease or another condition under active management at home — that continuity is worth more than the saving.

What to Bring

Any previous endoscopy or colonoscopy reports, with images if available
Current medication list, especially anticoagulants and antiplatelets
A note of your family history of colorectal or gastric conditions
Your home gastroenterologist’s contact details, in case a biopsy result needs follow-up

Common questions

How much does a colonoscopy cost in Thailand?

Published hospital prices in Bangkok start around 15,900-29,000 baht for colonoscopy alone, roughly $500-900. A combined gastroscopy and colonoscopy runs from about 24,900-39,400 baht depending on the hospital, commonly quoted as $1,000-1,100 all in.

What's usually excluded from the quoted endoscopy price?

Biopsy and histopathology are almost always billed separately — one hospital states this explicitly. Deep sedation administered by an anaesthesiologist, rather than the moderate sedation included as standard, is also an extra if your case needs it.

What does bowel prep for a colonoscopy in Thailand involve?

An oral laxative starting the evening before, a switch to a clear-liquid diet in the 24 hours beforehand, and 6 hours without food or drink before the procedure. If you take anticoagulants, expect to be asked to stop them 3-7 days ahead on your doctor's instruction — tell the clinic about any blood thinners when you book.

Which gastroenterology clinic does Wellmap verify in Thailand?

One: Phyathai 2 Hospital in Bangkok, a full-service international hospital with JCI and ISO 9001 accreditation, also known for bariatric and metabolic surgery.

Is a diagnostic trip to Thailand worth it for a routine screening?

For a standard screening colonoscopy with no complex findings expected, the price gap against home-country costs can be large enough to justify the trip even with flights added. For anything where a biopsy result might need urgent local follow-up, weigh the distance from your own gastroenterologist before booking.
