Gynecomastia is a recognised medical condition involving enlarged breast tissue in men, and it can have hormonal, medication related or other medical causes that a doctor should assess before any cosmetic consultation. The ten Bangkok gynecomastia surgery clinics ranked here are hospitals and clinics that publish a dedicated gynecomastia or male breast reduction procedure page on their own website. This page stays factual: what each provider states about separating glandular tissue from fat only enlargement, which technique it names for each presentation, whether it publishes a grading system, and what it discloses about anaesthesia and recovery. Nothing here is clinical advice, and no provider has paid for its position.
The reasoning behind our Bangkok gynecomastia rankings
Every entry comes from the provider's own published gynecomastia or male breast reduction page, read directly rather than through a directory. We recorded whether the page separates true glandular gynecomastia from fat only pseudogynecomastia, which surgical technique it names for each case, whether a grading or classification system is published, and what the page discloses about anaesthesia and hospital stay. We excluded general breast or body contouring pages that do not name gynecomastia specifically. Two things stay with the reader and cannot be settled from a website: a doctor's assessment of the underlying cause, and the treating surgeon's board certification.
Preecha Aesthetic Institute (PAI)
Preecha Aesthetic Institute sets out a three category breakdown on its gynecomastia and male breast reduction page: fat only cases treated with VASER liposuction, glandular tissue cases treated with excision, and mixed cases treated with both. The page states the surgery is performed at a JCI accredited hospital under general anaesthesia with one night's stay, sutures removed at seven days, a return to work at seven days, and a recommended minimum of eleven days in Bangkok before flying home. It names three board certified plastic surgeons, including institute founder Dr Preecha Tiewtranon, which is more surgeon detail than most providers in this ranking publish. Ask which of the three named surgeons would operate on you specifically.
Rattinan Clinic
Rattinan Clinic publishes the most clinically detailed gynecomastia page in this lineup, describing true gynecomastia as a firm rubbery lump beneath the nipple caused by glandular growth, distinct from the soft, diffuse fat of pseudogynecomastia. It names the Simon Classification from 1973, grading enlargement from mild puffiness through to severe sagging that needs skin excision, and states that mixed cases combine liposuction with gland removal through a small incision at the areola edge. Recovery notes include twenty four hour compression wear for the first three days, sutures removed around day seven, and a return to work in one to two days. Co-founder Dr Suthipong Treeratana is named with more than thirty years of body contouring experience.
Vejthani Hospital
Vejthani Hospital publishes a gynecomastia surgery page offering liposuction, excision or a combination, though unlike some competitors it does not explain which presentation calls for which technique beyond stating that breast size and desired result decide the approach. General anaesthesia is administered intravenously, the page describes the procedure as typically outpatient with same day discharge, and it estimates a return to work at around two weeks. A doctors who treat this condition section exists but does not name an individual surgeon or credentials, so confirm who would operate before scheduling. It suits a reader who wants a large accredited hospital setting rather than a boutique surgical clinic.
Yoskarn Clinic
Yoskarn Clinic distinguishes fat only pseudogynecomastia from true glandular gynecomastia on its male breast reduction page, and publishes three techniques: liposuction for fat, direct glandular tissue removal through a small areola incision for gland driven cases, and a combined method for mixed presentations. Anaesthesia is stated as local or general depending on the case. The recovery section is unusually granular, mapping expectations from day one through week six, with final results described at three to six months. Surgeon credentials stay generic, referring only to board certified plastic surgeons without naming anyone, so ask directly for the operating surgeon's name and registration.
Nirunda Clinic
Nirunda Clinic separates fatty fullness from excess glandular breast tissue on its gynecomastia and mastectomy page, describing a combined approach where liposuction sculpts the fat and any remaining glandular tissue is excised through a roughly one inch incision beneath the areola. General anaesthesia is stated for the procedure. Published recovery runs from a couple of weeks to a month for full recovery, with light exercise permitted after ten days and chest specific exercise avoided for two to four weeks. As with several providers here, this page does not name an individual surgeon either, only board certified surgeons in general, so ask for the operating doctor's name and Thai medical licence before booking.
Samitivej Plastic and Esthetic Surgery Institute
Samitivej Plastic and Esthetic Surgery Institute lists male breast reduction, described on the page as gynecomastia, among its breast procedures without a dedicated procedure page: no technique, anaesthesia, grading system or surgeon name is published for this specific operation. What the listing does offer is the wider Samitivej hospital network behind it, useful for a reader who wants full hospital infrastructure and other specialists on site if a complication needs different care. Because the public page stops at a single line, this is the entry in this ranking where a direct enquiry, not the website, has to answer nearly every clinical question before booking.
KKC Clinic
KKC Clinic publishes a dedicated gynecomastia surgery page naming liposuction, glandular excision and a combined approach, with an optional J-Plasma skin tightening add-on for looser skin after weight loss. The page states the procedure is done under general anaesthesia or IV sedation with local anaesthesia, and names two surgeons, Dr Peerajed Chaiyasuk and Dr Wutthiwat Anupansawang, describing each one's years of experience in body contouring and VASER liposuction. It states a compression garment worn four to six weeks, a return to desk work within a week and full workouts resuming at four to six weeks, though it does not publish a formal grading system for gynecomastia severity or state a hospital stay length.
Yanhee International Hospital
Yanhee International Hospital describes three techniques on its male breast reduction page: liposuction, a subcutaneous mastectomy performed through a periareolar incision, and a combined approach, and it distinguishes true glandular gynecomastia from fat only pseudogynecomastia without naming a formal classification scale. General anaesthesia or local anaesthesia with sedation are both offered, and the page names the operating surgeon, Dr Duangkamon Chiranakorn, with a stated medical degree from Prince of Songkla University and plastic surgery training at Siriraj Hospital. Published recovery includes one night in hospital, a compression garment, a follow up appointment at seven to ten days and a final shape described as settling over six to twelve months.
Bumrungrad International Hospital
Bumrungrad International Hospital lists gynecomastia surgery among its published treatments, stating only that the procedure removes fat, glandular tissue and, in more advanced cases, skin from the chest, without naming a specific technique such as liposuction or excision. Anaesthesia is offered as local anaesthesia with sedation or general anaesthesia, and the page states a return to desk work at five to seven days, avoiding strenuous activity for two to three weeks and full resolution of bruising over three to six months. No individual surgeon is named and no compression garment or hospital stay length is published, so this entry offers a large accredited hospital setting rather than procedure level detail, and a direct enquiry is needed to fill in the technique and surgeon question.
Before gynecomastia surgery in Bangkok, verify this
Gynecomastia can have hormonal, medication related or other medical causes, and a doctor should assess that before any cosmetic booking; this ranking does not replace that assessment. Because the underlying cause determines whether surgery is even the right next step, that clinical evaluation belongs before, not after, any consultation about technique or pricing.
When you do reach the consultation stage, ask three things directly: whether your case is glandular, fat only or mixed, since that decides the technique; what anaesthesia will be used and whether an anaesthesiologist is present throughout; and how many nights, if any, the provider expects you to stay in Bangkok afterwards. Ask to see the operating surgeon's name and Thai medical licence rather than accept a general claim that the team is board certified, and if any of this is unclear on the provider's own page, treat that as a reason to ask more questions, not less.
Budget and logistics matter too, but they should follow the clinical picture rather than lead it.

Nothing on this page is medical advice, and no provider has paid for its position here.
Kamol Cosmetic Hospital publishes a dedicated gynecomastia page naming three separate techniques: liposuction alone for excess fat, excision for breast tissue and skin, and a combined approach when both are present, with the page stating that the appropriate technique depends on individual examination. The hospital includes a published classification image but does not explain its grading criteria in the accompanying text, and it does not name an anaesthesia type beyond noting that patients meet the anaesthesiologist beforehand. Compression garment use runs several weeks and the page estimates a return to normal activity within a few weeks, though it does not state the hospital stay length. No individual surgeon is named on this page, so ask who will operate before booking.
