Dr. Visnu Lohsiriwat

Dr. Visnu Lohsiriwat (Thai: นพ. วิษณุ โล่ห์สิริวัฒน์) is a Thai plastic surgeon in Bangkok whose documented work concentrates on the breast and on body contouring. Bumrungrad International Hospital publishes him as Visnu Lohsiriwat, M.D., under two specialty labels: General Surgery and Plastic Cosmetic & Reconstructive Surgery. Siriraj Piyamaharajkarun Hospital (SiPH) gives his expertise as plastic and reconstructive surgery, breast aesthetic surgery, cosmetic breast reconstruction and breast oncology. He also teaches. His academic base is Siriraj, the medical faculty of Mahidol University: his CV and his own website describe him as a lecturer in its Division of Head-Neck and Breast Surgery, and the university's research portal files him under the surgery department there.

Official sources connect him with three Bangkok hospitals:

• [Bumrungrad International Hospital](/hospital/bumrungrad-international-hospital/), 33 Sukhumvit Soi 3 (Soi Nana Nua), Watthana. His Bumrungrad profile publishes no clinic timetable; the hospital's contact centre arranges outpatient times with him on request.
• [Siriraj Piyamaharajkarun Hospital](/hospital/siriraj-piyamaharajkarun-hospital/), 2 Wanglang Road, Bangkoknoi. SiPH places him in its Surgery Center (Head, Neck, Breast) and publishes a single clinic for him: Mondays, 16:00 to 18:00, in weeks two and four of each month.
• [Siriraj Hospital](/hospital/siriraj-hospital/), the university's teaching hospital, which shares the 2 Wanglang Road address and where he belongs to the surgical faculty.

His professional website, which uses his Thai nickname หมอบัว (Dr. Bua), groups his procedures into three families: breast surgery (silicone implant augmentation, lifts, reductions, implant revision and removal, and bilateral breast removal for trans men), liposuction with fat injection, and abdominal contouring that ranges from a mini tummy tuck to a circumferential 'belt' procedure. Among professional bodies, his closest confirmed link is to ThPRS, the Thai plastic surgery society: its online directory has a member entry for him, and its executive committee page includes his name.

If you are weighing up one of these operations, you can request a consultation with Dr. Visnu Lohsiriwat through our patient team. We contact the hospital you prefer, check what is available and reply to you; nothing is booked until that has been confirmed.

One point of identity is worth knowing when you search for him: the colorectal surgeon Varut Lohsiriwat, also at Siriraj, shares his family name. This profile is about Dr. Visnu Lohsiriwat, the plastic and breast surgeon.

Dr. Lohsiriwat took his medical degree at Siriraj, stayed there for both of his specialist residencies, and later trained in breast surgery in Italy and the United States. Unless a difference is noted, the years below are the same on his Bumrungrad and SiPH profiles, his ThPRS entry and his own website.

• Doctor of Medicine, 2000: Faculty of Medicine Siriraj Hospital, Mahidol University. His own website, his ThPRS entry and his 2018 CV record the degree with first-class honours; the Bumrungrad and SiPH profiles give the degree and year without mentioning honours.
• Internship, 2000–2001: Samutsakorn Hospital, according to his 2018 CV.
• Higher Graduate Diploma Program in Clinical Sciences, 2002: listed on the SiPH profile, which does not name the awarding institution.
• General surgery residency, 2001–2005: at Siriraj; his Thai Board of Surgery diploma followed in 2005.
• Plastic and reconstructive surgery residency, 2005–2007: also at Siriraj, which he finished in 2007 with the board diploma in plastic surgery.
• Observership, 2012: Memorial Sloan-Kettering Cancer Center, New York, as listed by SiPH.
• Fellowship in breast plastic and reconstructive surgery: European Institute of Oncology, Milan. SiPH dates it to 2013; his website and ThPRS entry give 2012; his 2018 CV lists the period as 2008–2013 together with a 'Certificate Research Fellowship Oncoplastic Reconstruction, 2013'.

Two Thai board diplomas. In Thailand, a doctor who finishes an approved residency in a specialty receives a board diploma (วุฒิบัตร) in that field. Dr. Lohsiriwat has two of these, in general surgery and in plastic surgery. The home page of his website uses the phrase 'Double Board Certified' for this combination, while his CV simply lists both diplomas. The pairing fits the way SiPH frames his expertise, which covers breast oncology alongside aesthetic and reconstructive breast surgery.

Licence. The licence can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th, and our patient team can help you confirm it before you travel. His ThPRS member entry gives licence number 25355. You can search the Medical Council's public register yourself under his Thai name, วิษณุ โล่ห์สิริวัฒน์, and the sourcing behind each statement on this page is described in our provider research methodology.

Posts listed as current

• Faculty of Medicine Siriraj Hospital, Mahidol University: lecturer (อาจารย์), consultant and permanent staff member in the Division of Head-Neck and Breast Surgery, Department of Surgery, since 2007 according to his 2018 CV. The Mahidol research portal and his 2026 journal affiliations place him in the same department. The Thai prefix อ. that SiPH puts before his name means lecturer; it is not a professorial rank.
• Siriraj Piyamaharajkarun Hospital: specialist in the Surgery Center (Head, Neck, Breast).
• Bumrungrad International Hospital: surgeon under General Surgery and Plastic Cosmetic & Reconstructive Surgery, with outpatient times given on request.

A clinic timetable on his website, valid from 6 April 2023, also lists a breast clinic at Siriraj Hospital on Monday and Tuesday mornings and a scar clinic at the hospital's skin laser centre on Monday afternoons. Clinic sessions at a public teaching hospital change over time, so read that timetable as background rather than as current opening hours.

Roles in professional bodies

• International Oncoplastic Breast Society (IOPBS): his website and ThPRS entry give his role as International Secretary (General Secretary), and SiPH includes IOPBS among the societies it lists for him.
• ThPRS: his membership shows on the society's own directory (entry first posted 28 November 2019 and updated 8 February 2024), and named on the executive committee page as assistant public relations officer. The page does not state the committee's term.
• The Royal College of Surgeons of Thailand: listed as a membership by SiPH, whose Thai-language page describes him as a subcommittee member.
• Academic journals: his 2018 CV lists him as an associate editor of Gland Surgery and on the editorial board of the Journal of Breast Cancer, and his website says he is an editor of Thai and international academic journals. Ask our patient team whether these roles are current.

His 2018 CV adds six further memberships: the Thai Breast Disease Society, the International College of Surgeons of Thailand, the Thai Society of Wound Healing, the European-Asian Society for Breast Disease, and the aesthetic surgery societies ISAPS (international) and ThSAPS (Thai). We have these six from his CV only: ThSAPS does not publish a member list, and we did not search the ISAPS directory.

Places named in older documents

His 2018 CV names consultant roles at Bangkok Hospital and the Phuket Plastic Surgery Institute, and the 2023 timetable lists a surgery clinic on the 9th floor of Vimut Hospital for cosmetic, revision and reconstructive breast surgery. On 27 September 2026, Vimut's doctor finder returned no match for him and the Phuket institute's website had no profile for him. Some medical-travel websites also connect him with Samitivej hospitals, but we found no official Samitivej page listing him. None of these appears here as a current place of practice. If you were referred to him at one of them, tell our patient team and we will ask.

Research

A PubMed search on his full author name returned 51 records when we checked on 27 September 2026. Examples published with his Siriraj affiliation include:

• a 2026 Gland Surgery study comparing outcomes of implant-based breast reconstruction with acellular dermal matrix, without it, and with TiLOOP® in breast cancer patients;
• a 2026 Gland Surgery prospective cohort study of immediate fat-augmented latissimus dorsi (FALD) flap reconstruction after mastectomy;
• a 2025 randomised controlled study in Archives of Dermatological Research on a fractional 1064-nm picosecond laser for minimising scars after mammoplasty in Asian patients;
• a 2024 meta-analysis in Annals of Surgical Oncology on implant-based reconstruction after mastectomy with and without acellular dermal matrix;
• the Oncoplastic Breast Consortium consensus conference on nipple-sparing mastectomy (Breast Cancer Research and Treatment, 2018);
• a 2014 Gland Surgery paper on metabolic syndrome and outcome after breast reconstruction.

Published research shows which clinical questions a surgeon works on. It is not evidence of the result any individual patient will get.

Every procedure below appears on Dr. Lohsiriwat's own website, mostly on service pages that present their lists as images. The general guidance in each part comes from our procedure guides and describes patients in general, not his results. Whether any of these operations suits you can only be decided after the surgeon has assessed you.

Breast augmentation with implants (our guide)

Silicone implant augmentation comes first on his breast page, with added fat injection or endoscopic assistance listed as options. In general, planning an augmentation means choosing the implant (silicone or saline, round or anatomical, smooth or textured), the incision (inframammary fold, areola edge or armpit) and the pocket, above the pectoral muscle or partly beneath it. Ask him which combination he proposes for your chest and why, and ask specifically about the implant surface, because some textured implants are associated with a higher risk of a rare lymphoma (BIA-ALCL). Implants are not lifetime devices, and most people should expect that, years later, the devices will need replacing or removing in a further operation. Our augmentation guide sets aside 7–10 days for the trip, long enough for the wound check.

Breast lift, alone or with implants (our guide)

Two lift options appear on his site: a lift combined with augmentation, using either a periareolar incision or a vertical or anchor pattern, and a lift that keeps the existing breast size. As a rule, more lift means a longer scar: a periareolar scar suits mild sagging, and vertical and anchor patterns are used as sagging increases. A lift reshapes rather than enlarges. If you also want more upper-breast volume, the implant may be placed in the lift operation itself or in a separate, staged operation; his list includes the combined option, so ask whether he would recommend one sitting or two in your case. For a lift, the guide's planning window is 10–14 days.

Breast reduction (our guide)

His breast page lists a lift with size reduction, and his biography names reduction among his breast operations. Reduction removes breast tissue, fat and skin and raises the breast in the same operation. Relief of neck, back and shoulder pain is a common reason for it, alongside shape, although results vary and other causes of pain should be assessed. Breastfeeding may not be possible afterwards, so mention any plans for a future pregnancy. Our guide gives a typical stay of 10–14 days, so wound healing can be checked before you fly.

Implant revision and implant removal (revision guide, removal guide)

This is the most detailed part of his breast list. For revision he lists three approaches: adjusting the existing implant pocket; removing the capsule (the layer of scar tissue that forms around every implant) and creating a new pocket; and that capsule-and-pocket revision combined with a lift. For old implants he lists removal alone, removal with complete capsule removal, and capsule removal with a lift. Which route fits depends on why you want a change: the implant itself, the capsule around it, a different size, or a wish to live without implants. Recovery and hospital stay after revision or removal vary with what is done, so ask him directly how long to plan in Thailand, and make sure the hospital's quote states what each option includes.

Fat transfer to the breast (our guide)

His liposuction page states that fat removed by liposuction can be injected into the breast, either to enlarge it or to correct its shape, and his implant augmentation can include fat injection. In general, fat transfer gives a modest increase in size, part of the transferred fat is reabsorbed, more than one session may be needed, and it depends on having fat available to harvest. Ask whether he would use fat alone or alongside an implant in your case. Our guide lists about 7–10 days in Thailand.

Liposuction (our guide)

The areas on his liposuction page are the upper and lower abdomen, the inner and outer thighs, the upper arms, the back, the hips and waist, the knees, and an area listed in Thai as ปีกไหล่. Liposuction reshapes; it is not a weight-loss treatment and does not tighten loose skin. Removing large volumes in one session raises the risk of fluid shifts, bleeding and blood clots, which is why the volume taken in one sitting is limited to what your weight and health allow, and larger plans are sometimes divided into stages. A compression garment is worn afterwards, swelling settles gradually over the following weeks, and the final contour usually becomes visible over 3–6 months. For liposuction our guide's range is 7–10 days in the country; a big-volume session, many treated zones or an added operation lengthens that.

Tummy tuck: mini, full, extended and belt

His abdominal page lists four versions, each with a matching guide on our site: a mini tummy tuck, a full tummy tuck (his home page also lists abdominoplasty as a service), an extended tummy tuck and a circumferential belt procedure, which we cover under body lift. In general, a full abdominoplasty uses a low hip-to-hip incision, usually repairs separated abdominal muscles and repositions the navel; a mini version treats loose skin below the navel through a shorter incision; an extended version carries the incision further round the sides to treat the flanks; and a belt procedure continues the incision around the body. Surgeons usually advise waiting until you have finished having children and your weight has been stable for some months, and smoking must stop well before surgery. Among cosmetic operations, the tummy tuck sits in the higher band for blood-clot risk, so ask about clot prevention for the flight home. Our guide suggests about 12–14 days in Thailand, and longer after extended or combined procedures.

Top surgery for trans men (our guide)

His breast page lists bilateral breast removal for female-to-male patients. It does not say which techniques he uses or what documentation he asks for. In general, the technique depends on chest size and skin elasticity: a double-incision operation, with the nipples removed and regrafted, is the common approach for medium and larger chests, while periareolar or keyhole methods are kept for smaller chests with firm skin. Many surgeons follow WPATH SOC-8, which does not require hormone therapy before chest masculinization, but each surgeon sets their own requirements. Bumrungrad's Pride Clinic names other surgeons on its transgender plastic surgery team, so ask our patient team where he would carry out this operation. Expect around 10–14 days in Bangkok by our top surgery guide's reckoning, because drains usually come out and the nipple grafts are inspected before anyone flies.

Breast reconstruction and breast cancer surgery

SiPH lists breast reconstruction after mastectomy and breast cancer surgery, including cancer surgery combined with augmentation, among his interests, and his website lists surgery for benign breast tumours and breast cancer. His breast page also includes nipple and areola reshaping. We do not yet have procedure guides for these operations. If you are living with a breast cancer diagnosis, your treatment is planned with your oncology team; our patient team can pass on a request for a consultation, but cannot advise on cancer care.

Not on his documented lists. Face, eyelid and nose operations do not appear on the procedure lists we found for him; a 2013 co-authored paper on augmentation rhinoplasty is among his PubMed records, but his current service pages do not offer nose surgery. If facial surgery is what you are looking for, start from our procedure guides.

A first consultation with Dr. Lohsiriwat is where you agree what is realistic for your body, where the operation would take place and how aftercare works once you are home. Because his documented work runs from breast implants to abdominal contouring, the most useful questions depend on the operation you have in mind.

For any operation

• At which hospital would the surgery take place, and who gives the anaesthetic?
• How many nights would I spend in hospital, and when would you expect me to be fit to fly?
• What does the written quote include: surgeon, hospital, anaesthesia, garments and follow-up visits? What happens if a revision is ever needed?
• Whom do I contact about my wounds or recovery after I return home?

For implants, revision or removal

• Which implant brand, surface, shape and size do you suggest, and why that surface?
• Which incision and which pocket, in front of or behind the muscle?
• Would you add fat injection or use an endoscope in my case? Both appear on his list of options.
• For a revision: will you keep my current pocket or create a new one, and will the capsule come out?
• For a removal: will the capsule be removed completely, and am I likely to need a lift to reshape the breast afterwards?
• Will I receive an implant card with the brand, size, type and lot numbers for my records?

For lifts and reductions

• Which scar pattern, around the areola, vertical or anchor, does my degree of sagging call for?
• If I also want an implant, would you do the lift and the augmentation together or in two stages?
• What could the operation mean for breastfeeding and nipple sensation?

For liposuction, fat transfer and tummy tuck

• How much fat can safely be removed in one session, given my weight and health?
• Would a mini, full, extended or belt tummy tuck suit my abdomen, and would my abdominal muscles be repaired?
• Would you combine liposuction with the tummy tuck, and does that change how long I should stay in Thailand?
• What clot-prevention steps do you recommend around surgery and the flight home?

For top surgery

• Which technique suits my chest size and skin?
• What letters or assessments do you require before surgery?
• How will nipple grafts be checked, and when can I travel?

In general, it helps to write your questions down before the appointment and, if English is not your first language, to ask the hospital in advance about an interpreter.

Of Dr. Lohsiriwat's three listed hospitals, Bumrungrad International Hospital is the one with documented services for patients travelling from abroad. The Bumrungrad details below come from the hospital's own pages and from the accreditors' directories.

Bumrungrad International Hospital (33 Sukhumvit Soi 3, Soi Nana Nua, Watthana)

• Coordination for patients from abroad sits with a dedicated Medical Coordination Office, found in Building A on level 10. Before arrival it reviews records, gives price estimates, sets appointments and offers telemedicine; it stays involved during the admission; once you leave hospital, it handles the medical report, the fit-to-fly document and any follow-up arrangements. The hospital describes the service as complimentary.
• Language help is well documented: according to the Bumrungrad factsheet the interpreter team numbers over 130, and the hospital also mentions cultural support officers for travelling patients more comfortable in another language than English.
• Transport help includes a hospital desk in the Suvarnabhumi Airport arrivals area; a complimentary van that leaves the airport roughly hourly, depending on passenger numbers, for Bumrungrad or hotels close to it; and free shuttles from the BTS Nana and BTS Phrom Phong stations.
• The Business Center books hotels and flights, and it can handle visa-extension paperwork with the immigration authorities in Bangkok for a patient and anyone accompanying them.
• Bumrungrad holds JCI hospital accreditation and HA Thailand advanced hospital accreditation, the latter valid to 22 May 2029. JCI also lists a Breast Cancer clinical care program certification for the hospital, effective 30 May 2025; his profile does not say whether he works within that program.
• The hospital's Plastic (Cosmetic) Surgery Center is on the 16th floor of Building A and sees patients by appointment. His profile does not name the clinic where he consults, so the confirmed location comes with your appointment.

Siriraj Piyamaharajkarun Hospital (2 Wanglang Road, Bangkoknoi)

Our research on SiPH covered his listing and clinic times, not the hospital's services for patients from abroad. Because his published clinic there runs only on Monday late afternoons, twice a month, a SiPH consultation needs travel dates that fit that window.

Siriraj Hospital

Siriraj is a public university hospital, and the 2023 timetable on his website is the only schedule we have for him there. If you specifically want to be seen at Siriraj, tell our team and we will ask how an appointment with him can be arranged.

Length of your trip

For the operations on his lists, our procedure guides point to these general ranges: 7–10 days in Thailand around breast augmentation, fat transfer to the breast or liposuction; 10–14 days around a breast lift, breast reduction or top surgery; and 12–14 days around a full tummy tuck, more when it is extended or combined with other work. Revision, implant removal and a belt procedure vary too much for a standard figure, so ask him directly. Only the surgeon who operated can clear you to fly. Around a long flight after liposuction or a tummy tuck, walk regularly, keep well hydrated and ask about clot prevention such as compression stockings. After breast surgery, pack button-up or zip-front tops, and line up someone to carry heavy bags for you.

Language. Bumrungrad lists Thai and English for Dr. Lohsiriwat, and his 2018 CV adds Italian.
