Gastric sleeve cost in Bangkok: hospital packages, what they include, and the stay

What a gastric sleeve costs in Bangkok

On 2 November 2026 we read the weight-loss surgery prices that three Bangkok hospitals and one Bangkok clinic publish on their own websites:

What the surgeon does	Published prices
Gastric sleeve	From 430,000 to 450,000 baht at the clinic, with four nights in hospital; 500,000 to 550,000 baht at one hospital, with four nights; 640,000 baht at another hospital for keyhole surgery, with three nights.
Gastric sleeve, robotic	700,000 baht at that hospital, with three nights.
Gastric bypass	From 600,000 to 650,000 baht at the clinic, or 630,000 baht for a mini bypass, with four nights.
Changing a sleeve to a bypass	From 690,000 baht at the clinic, with four nights.
Gastric balloon, with no incision	165,000 baht at a third hospital for a balloon that stays six months, or 234,000 baht for one that stays a year, with one night; from 230,000 baht at the clinic.

The hospital with the highest prices says they apply only to patients flying in from abroad and are valid until 31 December 2026. The clinic gives starting prices, and says a high BMI may add an anaesthetist's fee or the cost of special techniques.

What the package covers, and what it leaves out

Two hospitals list what their package includes: the surgeon and the anaesthetist, the operating room, the room, nursing and food for the stated nights, and the supplies and medicine for the operation. The clinic's package adds a consultation, care after surgery, a leak test, a health check and a ride from the hospital, with follow-up for up to two years.

Both hospitals leave out the tests and checks before surgery, specialists' fees for other conditions, and the cost of complications or extra time in intensive care. One also leaves out laboratory tests, pathology and medicine to take home. None of the four lists flights or a hotel; the clinic says both are extra.

How long to stay

You stay three nights in hospital at one hospital and four at the others. The clinic advises about 10 to 14 days in Bangkok for surgery, recovery and follow-up, and suggests planning at least two weeks.

The Thai guideline sets a diet on each side of the operation. Before it, a liquid diet of under 800 calories a day, with 60 to 80 grams of protein and at least 1.8 litres of water, for about a week, or two weeks if your BMI is over 50. After it, clear liquids on the first day and, if those go well, thicker liquids on the second, soft food for the first two to four weeks, and normal food in small meals, about 1,000 calories a day, from one month.

It also sets follow-up over the first year: with the surgeon at one week, one month and one year, and with a dietitian at 1, 3, 6, 9 and 12 months, with vitamins and calcium taken every day. Arrange who will see you at home before you go. None of the four says when you can fly; ask your surgeon before you book your flight home.

Who qualifies, and checking the surgeon

The Thai Society for Metabolic and Bariatric Surgery's guideline, published in 2020 and revised in Thai in 2021, says surgery should be considered for Thai patients with a BMI of 37.5 or more, or 32.5 or more with related illnesses that full treatment has not controlled. For type 2 diabetes or metabolic syndrome that lifestyle changes and standard treatment have not controlled, it may be considered from a BMI of 30; between 27.5 and 30, only under strict medical supervision, with your consent and an ethics committee's approval.

The guideline recommends surgery between the ages of 18 and 65, with other ages decided by a team of specialists. It asks patients to show their commitment: to lose 5 to 10% of their weight before the operation, to attend at least 80% of the appointments before it, and to understand the operation and the care after it. It says it is not a rigid rule or a legal standard; the surgeon decides with you. One hospital says its package depends on your condition and the surgeon's assessment.

Only a doctor registered and licensed by the Medical Council of Thailand may practise medicine (Medical Profession Act 1982, section 26). You can check a doctor on the Medical Council's website by searching their first name and surname, in Thai or in English. It lists only licensed doctors. If you find nothing, the Council answers on 02-590-1887. No one may present themselves as skilled in a field of medicine unless they hold the Medical Council's certificate for it, or one the Council recognises, or meet criteria set in the Council's regulations (section 28). The Thai guideline says the surgeon should be specially trained in this surgery. Ask which certificate your surgeon holds.

What to ask before you pay

Do I meet the Thai guideline's criteria, and what preparation do you need from me before the operation?
Are the tests before surgery included, and what do they cost?
What happens, and who pays, if there is a complication or I need intensive care?
How many nights in hospital, and when can I fly?
What follow-up is included once I am home?
What is the surgeon's full name, and which Medical Council certificate do they hold?
