- Published screening prices on the pages we read ranged from 19,500 baht for a gastroscopy to 64,500 baht for a combined gastroscopy and colonoscopy.
- Screening packages commonly exclude biopsy and polyp removal, which are only known to be needed during the procedure.
- Sedation is not always mentioned; ask whether it is included and who gives it.
- Bangkok Hospital's headquarters screening packages are for people aged 45 and over, for Thai nationals and expatriates, and not for diagnosing existing symptoms.
- Bowel preparation the day before a colonoscopy is part of the process, so plan time around it.

Gastroscopy, colonoscopy and what they look at
A gastroscopy (upper endoscopy) passes a thin camera through the mouth to examine the oesophagus, stomach and the first part of the small intestine. A colonoscopy passes a camera through the back passage to examine the large bowel. Both can be done on the same day, and hospitals in Thailand often sell them separately and as a combined package.
Colonoscopy is used both to investigate symptoms and to screen for bowel cancer and polyps in people without symptoms. The Bangkok Hospital headquarters packages we read are explicitly for preventive screening in people aged 45 and over, and say they are not intended for diagnosis or follow-up of existing conditions. If you have symptoms such as bleeding, a change in bowel habit or weight loss, the hospital is likely to want you to see a gastroenterologist first, and that visit is charged separately.
What the published prices include
On the pages we read, Bangkok Hospital's headquarters listed a gastroscopy at 19,500 baht, a colonoscopy at 26,800 baht and both together at 39,000 baht, including the standard procedure and the endoscopist's and outpatient physician's fees on the day. Biopsies and other additional procedures, extra specialists and treatment after the examination are excluded.
Bangkok Hospital Samui's package is priced higher, at 46,500 baht for a colonoscopy and 64,500 baht for both, but includes pre-procedure blood and urine tests, an ECG, a chest X-ray and the bowel preparation medicine. It excludes clearance by an internal-medicine physician, specialist fees, pathology and minor procedures beyond a standard examination. The two sets of figures therefore cover different things and should not be compared on price alone.
Biopsy, polyp removal and sedation
The main source of extra cost is what is found. If the doctor sees a polyp or an area that needs testing, they may remove it or take a biopsy during the same procedure, and the tissue is sent to a pathologist. Packages we read exclude these, because nobody knows in advance whether they will be needed. Ask the hospital for an indication of what polyp removal and pathology typically add, and whether it will seek your consent for extra charges before proceeding.
Sedation practice varies. Some procedures are done with a local anaesthetic throat spray or block, others with intravenous sedation or a general anaesthetic given by an anaesthetist. The Bangkok Hospital headquarters pages do not mention sedation, and Samui lists a 'local block' gastroscopy separately from a standard one. Ask whether sedation is included, who gives it, and whether you need someone to take you home afterwards.
Preparing for a colonoscopy
A colonoscopy needs a clear bowel. Hospitals give instructions on diet in the days before and a laxative preparation to drink, usually the evening before and sometimes the morning of the procedure. This takes time and means staying close to a toilet, so plan the day before as well as the day itself.
Tell the hospital in advance about medicines you take, especially blood thinners, diabetes medicines and iron tablets, as some may need to be adjusted. Do not change prescribed medicines without advice from the doctor who prescribed them or the endoscopy team.
Eligibility, coupons and insurance
The Bangkok Hospital headquarters packages are sold as e-coupons, must be used between 25 July and 31 December 2026, and are for Thai nationals and expatriates; without the coupon the full price applies. Visitors should ask what price applies to them.
Insurers often treat screening and diagnostic endoscopy differently. A screening package bought as a promotion may not be claimable, while an endoscopy ordered by a doctor for symptoms may be. Check with your insurer before booking, and ask the hospital for an itemised bill and an English report including any pathology results.
Public and university hospitals also perform endoscopy, usually at lower cost, but non-urgent waits can be long and prices for foreigners are rarely published in English. Pathology results generally take several days, so if you are travelling, ask how results will reach you and who will explain them if you have already left.
Questions to ask before you book an endoscopy
- Is this a screening package, and am I eligible as a visitor or resident?
- Is sedation included, and who gives it?
- What would a biopsy or polyp removal and pathology add to the bill?
- Are pre-procedure tests and bowel preparation medicine included?
- Do I need to see a specialist first, and what does that consultation cost?
- When will I receive the report and any pathology results in English?
Frequently asked questions
How much does a colonoscopy cost in Thailand?
On the official pages we read in October 2026, Bangkok Hospital's headquarters listed a screening colonoscopy at 26,800 baht and Bangkok Hospital Samui at 46,500 baht, with different inclusions. Biopsy and pathology were extra at both.
How much does a gastroscopy cost?
Bangkok Hospital's headquarters listed a screening gastroscopy at 19,500 baht; Bangkok Hospital Samui listed 24,000 baht with a local block and 37,500 baht for its standard gastroscopy package.
Is sedation included?
Not always, and some pages do not say. Ask whether sedation is included, what type, and who gives it.
What if they find a polyp?
It may be removed or biopsied during the procedure and sent for testing. The packages we read exclude these extra procedures and pathology, so ask for an estimate in advance.
Can I use a screening package if I have symptoms?
Bangkok Hospital's headquarters packages say they are for preventive screening, not diagnosis. If you have symptoms, expect to see a specialist first.
