Bangkok's private hospitals publish a range of physician-led weight management options, from tiered wellness assessments to bariatric surgery departments with years of published follow-up protocols. The seven providers listed here all publish a medically supervised weight management or bariatric surgery service on their own website today, led by named physicians, endocrinologists or surgical teams rather than a single injection or drip. This page does not promise a result, does not state a weight loss amount and does not recommend a specific medication. It sets out what each provider publishes about its team, its services and its follow-up care, so a reader can shortlist a provider before making contact directly.
How we assessed these providers
Each entry is drawn from the provider's own published centre or programme page: what it states about physician or specialist involvement, the wider care team, diagnostic or surgical services offered, and any follow-up schedule. We excluded providers whose published offer is limited to slimming injections, fat dissolving treatments, detox programmes or intravenous drips with no stated physician supervision, since those fall outside the medically supervised weight management this page covers. Nothing here recommends a specific medication, states a weight loss amount, or promises a result of any kind.
BDMS Wellness Clinic
BDMS Wellness Clinic runs a tiered weight management programme it calls Your Weight, Your Way, stating that expert physicians guide the assessment while trainers, nutritionists, dietitians and a sports wellness specialist deliver the plan. The published programme includes body composition analysis, hormone and micronutrient testing, blood work covering lipids, glucose and organ function, and a structured eight-week exercise component, with three assessment tiers offering different depths of testing. Readers drawn to a diagnostic-heavy starting point, rather than a single consultation, are the natural fit here. Ask which tier includes a named supervising physician and how often you will be reassessed, since the tiers differ mainly in testing depth.
Praram 9 Hospital
Praram 9 Hospital addresses weight through its Diabetes and Metabolic Center, whose centre page names six physicians and describes a multidisciplinary team of nutritionists, pharmacists and physical therapists, stating that a weight loss programme is used to prevent diabetes complications and related conditions. The centre is on the third floor of Building A. This option fits someone whose weight goals sit alongside a diabetes or metabolic diagnosis rather than a purely cosmetic aim, since the programme is framed around disease prevention. Ask whether the centre offers a standalone weight management pathway for someone without a metabolic diagnosis, since the published page addresses weight mainly in that context.
Vejthani Hospital
Vejthani Hospital runs its Endocrinology, Diabetes and Clinical Nutrition Center on the fifth floor, and its centre page states the centre was set up partly to meet the needs of patients with obesity, staffed by five named endocrinologists and supported by registered dietitians who provide consultations. The page describes consultation, diagnosis, prevention and treatment as its scope, without detailing one structured programme. A reader who wants an endocrinologist involved from the outset, particularly where weight concerns overlap with a thyroid or metabolic condition, will find this the more relevant fit. Ask for the specific weight management pathway and how often the dietitian team reviews progress, since the page describes the centre's scope rather than naming one programme.
Bumrungrad International Hospital
Bumrungrad International Hospital addresses obesity through both its Endocrinology, Diabetes and Clinical Nutrition Center and its Digestive Disease Center, and its obesity page states that nutrition counselling sits with the endocrinology centre while surgical options, including laparoscopic sleeve gastrectomy, endoscopic sleeve gastroplasty and bariatric endoscopy, sit with the digestive disease team. The page also references medication as one treatment path without naming a specific drug. Someone wanting both a non-surgical and a surgical route weighed within one hospital before choosing would be well served here. Ask which centre will coordinate your case if you are referred between the two, since the page describes two separate departments rather than one weight clinic.
Phyathai 2 Hospital
Phyathai 2 Hospital publishes a bariatric surgery article describing sleeve gastrectomy, Roux-en-Y gastric bypass and a sleeve-plus procedure performed by a team of specialised doctors and multidisciplinary professionals. The page states that doctors monitor patients with follow-up appointments at two weeks, one month, three months and two years, and that follow-up includes consultations with endocrinologists and cardiologists. For a reader who wants a long-term follow-up schedule set out in writing before surgery, rather than arranged afterwards, this published timeline stands out. Ask for the names and qualifications of the specific surgical team assigned to your case, since the article describes the pathway rather than naming individual doctors.
Phyathai 3 Hospital
Phyathai 3 Hospital runs a bariatric surgery service through its Advanced Surgical Interventional Technologies unit, and its bariatric surgery article describes laparoscopic gastric surgery performed through roughly five small abdominal incisions, each under two centimetres. The page sets out a staged post-operative diet moving from liquid to soft food over the following weeks, and states that ongoing behavioural support for eating habits remains part of sustained results. Its location makes it a practical choice for a reader on the Thonburi side of Bangkok seeking a minimally invasive surgical option close to home. Ask which specialists are involved in the multidisciplinary follow-up beyond the surgical team, since the article focuses mainly on the operation itself.
Samitivej Sukhumvit Hospital
Samitivej Sukhumvit Hospital runs bariatric surgery through its Surgery Clinic, based on Building 3, 1st floor of the Sukhumvit campus, alongside laparoscopic gallbladder, hernia and colonic procedures. The hospital's public directory of services confirms bariatric surgery is one of the specialties available at this specific location, distinguishing it from other Samitivej branches that offer different weight loss packages such as an adjustable gastric balloon at its Srinakarin site. Samitivej also lists several named surgeons with bariatric surgery credentials, including fellowship training in advanced laparoscopic and endoscopic bariatric techniques. Readers should ask which surgeon at the Sukhumvit campus performs bariatric procedures and what pre-operative workup is required, since the clinic page describes general surgical capacity rather than a single dedicated weight loss pathway. Details are on the hospital's Surgery Clinic page.
Bangkok Hospital (Headquarters)
Bangkok Hospital, the BDMS network's flagship campus on Soi Soonvijai, publishes a Weight Management and Obesity Clinic distinct from its surgical bariatric pages, describing a multidisciplinary team of endocrinologists, nutritionists, bariatric surgeons, rehabilitation specialists and health psychologists working together on both conservative and surgical treatment. Conservative options include personalized nutrition and exercise planning supported by Bioelectrical Impedance Analysis body composition testing, while the surgical arm covers laparoscopic gastric banding, sleeve gastrectomy and gastric bypass performed by the same clinic's bariatric surgeons. This combined structure makes it a comparison point for readers who want medical weight management assessed before any decision about surgery is made, rather than a surgery-first pathway. See the clinic's own overview page.
Yanhee International Hospital
Yanhee International Hospital publishes gastric balloon insertion as a non-surgical, medically supervised weight loss procedure that must be performed in a hospital setting by a specialist and supporting team, rather than a walk-in aesthetic treatment. The hospital states candidates typically fall within a BMI range of 30 to 50, must commit to accompanying lifestyle changes, and cannot proceed if they have had prior stomach surgery or certain gastrointestinal conditions. Because Yanhee is more widely known for cosmetic and plastic surgery, this page is useful specifically for readers comparing its medically supervised obesity procedure against the surgical bariatric programs published by other hospitals on this list, rather than against its cosmetic body-contouring services. Review the eligibility criteria on the hospital's gastric balloon page.
Piyavate Hospital
Piyavate Hospital lists Surgery and Treatment of Obesity as one line item within its wider Surgery Center, covering gastric balloon insertion for weight loss and laparoscopic gastric reduction alongside the center's cancer, laparoscopic and cardiac surgery services. The hospital names more than two dozen surgical specialists attached to the center, though its published page does not single out which of them lead the obesity service specifically, so readers should ask directly which surgeon performs bariatric procedures and how many cases they have handled. The center states it holds Hospital Accreditation (HA) and Joint Commission International (JCI) accreditation, which readers can independently verify before booking a consultation. See the hospital's Surgery Center page for the full service list.
Vibhavadi Hospital
Vibhavadi Hospital publishes a detailed gastric sleeve surgery page that sets eligibility at a BMI of 40 or higher, or 35 or higher with a condition such as type 2 diabetes, high blood pressure or sleep apnea, and describes a pre-operative process that includes nutritional and psychological assessment before scheduling. The hospital states its program is led by bariatric surgeons supported by specialized nurses, and it separately lists an Obesity and Weight Management Clinic and an Endocrinology and Metabolism Center among related services, suggesting a wider internal referral network beyond the surgical page itself. Readers should confirm which of these related clinics they would actually be assessed by first, since the surgery page describes the operation rather than the intake process. Full detail is on the hospital's gastric sleeve surgery page.
What to confirm before you start a programme
Weight management is a medical matter, and published programmes vary a great deal in what they actually include, from a single consultation to a full surgical pathway with years of follow-up. Before you commit, confirm in writing who supervises the programme day to day, whether that person is a physician or a specialist, and what follow-up is included once the initial programme ends. Ask how progress is measured and reviewed, and whether nutrition, exercise and any medical or surgical component are coordinated by the same team.
Prices and specific services quoted here come from each provider's own page and can change, so confirm them directly before you book anything. It is also worth asking each provider in writing what happens if your case turns out to need a different pathway than the one you first enquired about, for example if an assessment suggests a surgical route where you had expected a non-surgical programme, or the reverse. A clear answer at this stage tells you how the team communicates once you are an actual patient rather than an enquiry.
If you are researching non-surgical medical options as part of your decision, it is worth reading up separately on how these are regulated and supplied locally, such as this overview of Ozempic in Thailand, so that any conversation with a provider about medication starts from an informed position. Whatever pathway you are weighing, treat the material on this page as a starting point for questions rather than a final answer, and get everything that matters to your decision confirmed directly by the provider before you commit any time or money.
MedPark Hospital operates a bariatric surgery service through its Gastrointestinal and Liver Center, and its bariatric surgery page states that the surgical team works alongside physicians, dietitians and nutritionists who provide post-surgery instructions and a phased return to regular food over several weeks. The hospital lists laparoscopic sleeve gastrectomy and gastric bypass among its published procedures. It suits a reader who wants a surgical pathway backed by a hospital-wide multidisciplinary follow-up team rather than a standalone clinic. Ask what pre-operative assessment is required and who supervises your specific case, since the page describes the general pathway rather than an individual treatment plan.
