Its stated mission is simple but ambitious: \u003cstrong\u003e\"to aspire to provide the most credible and transparent information available on bariatric\/metabolic surgery.\"\u003c\/strong\u003e This report is the seventh edition of its global registry series, released in August 2022.\u003c\/p\u003e\n\n\u003cp\u003eWhat exactly is a registry? According to the Agency for Healthcare Research and Quality, a registry is an organized system that uses observational methods to collect uniform data — clinical and other — to evaluate specific outcomes for a population defined by a particular disease or condition. When data is collected reliably and prospectively, it gives researchers a unique opportunity to understand patterns of disease and the real-world effects of treatments.\u003c\/p\u003e\n\n\u003cp\u003eThe history of this registry shows how far the field has come. The first IFSO Global Registry Report was produced in 2014, drawing on contributions from \u003cstrong\u003e18 countries across 5 continents, with 100,092 operation records\u003c\/strong\u003e — of which 53,197 were performed in the calendar years 2011–2013. In that first report, contributions varied enormously: one individual centre entered just 24 operation records, while two countries with established national registries (Sweden and the United Kingdom) each contributed over 34,000 records.\u003c\/p\u003e\n\n\u003cp\u003eBy the sixth report, the registry had grown to \u003cstrong\u003e507,298 operations from 50 contributor countries and 5 national registries\u003c\/strong\u003e. However, the project faced significant obstacles. These included a lack of consistent definitions for data fields (making true comparisons between countries difficult), and the fact that some countries were represented by a single surgical centre, which meant the data did not accurately reflect the entire country's activity. The introduction of the General Data Protection Regulation (GDPR) in Europe in May 2018 also changed how individual patient data could be collected and shared, placing new responsibilities on IFSO as the data controller.\u003c\/p\u003e\n\n\u003ch2 id=\"methods\"\u003eStudy Methods: How the Data Was Collected\u003c\/h2\u003e\n\n\u003cp\u003eThis seventh report represents a fundamental change in approach. Unlike the first six reports, which were based on individual-level patient data, this report contains \u003cstrong\u003eonly aggregated data\u003c\/strong\u003e from established national or regional bariatric surgery registries. No individual patient data was collected.\u003c\/p\u003e\n\n\u003cp\u003eIFSO knew of \u003cstrong\u003e32 national or regional registries\u003c\/strong\u003e worldwide. Of these, \u003cstrong\u003e25 agreed to participate — 23 national registries and 2 regional registries\u003c\/strong\u003e (Ontario in Canada and Michigan in the United States). This means that \u003cstrong\u003e78.1% of all known registries\u003c\/strong\u003e are represented in the report. The operations included were performed in either \u003cstrong\u003e2020 (for the USA) or 2021 (for the rest of the world)\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe data collection team at the Australia and New Zealand Bariatric Surgery Registry (ANZBSR) — Jennifer Holland, Angus Campbell, Robin Thompson, Jenifer Cottrell, and Dianne Brown — created a data dictionary, built a secure REDCap database housed at Monash University in Melbourne, Australia, and collected the aggregated data from each registry. The Data Vision Lab in the Netherlands then performed the analysis and created the visualizations.\u003c\/p\u003e\n\n\u003cp\u003eThe datasets focused on three key areas: the \u003cstrong\u003edemographics\u003c\/strong\u003e of people undergoing weight loss surgery, the \u003cstrong\u003etypes of procedures\u003c\/strong\u003e being performed, and markers of \u003cstrong\u003eperioperative safety\u003c\/strong\u003e (outcomes around the time of surgery, such as length of hospital stay, readmissions, and deaths). Because each registry already collected data according to its own definitions, it was not possible to perfectly align every dataset — where important definitional differences existed, they are flagged in the report.\u003c\/p\u003e\n\n\u003cp\u003eImportant caveats remain even with this improved structure. Very few registries achieve complete data ascertainment, meaning not 100% of people who undergo bariatric procedures are included in their registry. Not all registries have complete follow-up in the perioperative period, so some complications may not have been recorded. Registries also differ in how they audit or confirm data accuracy. These limitations are important to keep in mind when reading the results.\u003c\/p\u003e\n\n\u003ch2 id=\"demographics\"\u003eKey Finding 1: Who Is Having Weight Loss Surgery?\u003c\/h2\u003e\n\n\u003cp\u003eThe report looked closely at the age, sex, and body mass index (BMI) of patients undergoing weight loss surgery. BMI is a measure of body fat based on height and weight; a BMI of 30 or higher indicates obesity, and a BMI of 40 or higher indicates severe (or \"morbid\") obesity.\u003c\/p\u003e\n\n\u003cp\u003eOne finding was consistent across every single reporting registry: \u003cstrong\u003ethe majority of patients were female\u003c\/strong\u003e. This pattern held true in all countries and regions, reflecting a well-known global trend in who seeks out weight loss surgery.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003emedian starting BMI\u003c\/strong\u003e of patients varied significantly by country. The lowest median starting BMI was \u003cstrong\u003e36.8 kg\/m² in China\u003c\/strong\u003e, followed by \u003cstrong\u003e54.1 kg\/m² in Azerbaijan\u003c\/strong\u003e at the other end of the spectrum. The majority of registries reported starting BMIs in the \u003cstrong\u003e40–45 kg\/m² range\u003c\/strong\u003e, which is firmly in the severe obesity category.\u003c\/p\u003e\n\n\u003cp\u003eAge also varied. The median patient age was just \u003cstrong\u003e25 years in Kuwait and 32 years in China\u003c\/strong\u003e, compared to \u003cstrong\u003e44 years in the Netherlands, Italy, and New Zealand\u003c\/strong\u003e. This wide range suggests that different countries have different patterns of when patients pursue surgery — some earlier in life, others later.\u003c\/p\u003e\n\n\u003ch2 id=\"procedures\"\u003eKey Finding 2: What Operations Are Being Performed?\u003c\/h2\u003e\n\n\u003cp\u003eThe report catalogued the types of weight loss operations being performed worldwide, distinguishing between \u003cstrong\u003eprimary procedures\u003c\/strong\u003e (a first-time weight loss surgery) and \u003cstrong\u003erevisional procedures\u003c\/strong\u003e (a second surgery to correct or revise a previous one).\u003c\/p\u003e\n\n\u003cp\u003eThe most common procedure across all registries was \u003cstrong\u003esleeve gastrectomy\u003c\/strong\u003e — a procedure in which roughly 80% of the stomach is removed, leaving a banana-shaped tube. The second most common was \u003cstrong\u003eRoux-en-Y gastric bypass\u003c\/strong\u003e, which creates a small stomach pouch and reroutes part of the small intestine. These two operations form the backbone of modern bariatric surgery.\u003c\/p\u003e\n\n\u003cp\u003eThe report also noted an increasing number of \u003cstrong\u003e\"other\" procedures\u003c\/strong\u003e — including operations like the single-anastomosis (one-anastomosis) gastric bypass — particularly in the revisional setting. This suggests that surgeons are expanding their toolkit for patients who need a second operation after an initial procedure.\u003c\/p\u003e\n\n\u003cp\u003eIn terms of surgical technique, the \u003cstrong\u003emajority of operations were performed laparoscopically\u003c\/strong\u003e — meaning through small \"keyhole\" incisions rather than one large open incision. However, the report highlighted that the uptake of \u003cstrong\u003erobotic surgery continues to increase\u003c\/strong\u003e, especially for revisional procedures. Robotic surgery uses computer-assisted instruments that give the surgeon enhanced precision and control.\u003c\/p\u003e\n\n\u003ch2 id=\"diseases\"\u003eKey Finding 3: Obesity-Related Diseases in Surgical Patients\u003c\/h2\u003e\n\n\u003cp\u003eObesity is rarely an isolated condition — it is often accompanied by other chronic diseases, known as \u003cstrong\u003ecomorbidities\u003c\/strong\u003e (diseases that occur at the same time as another condition). The report examined which obesity-related diseases were most common among patients undergoing weight loss surgery.\u003c\/p\u003e\n\n\u003cp\u003eThe most frequently reported preoperative comorbidity was \u003cstrong\u003etype II diabetes\u003c\/strong\u003e. The highest rates of type II diabetes among people undergoing bariatric surgery were seen in \u003cstrong\u003eMichigan (USA)\u003c\/strong\u003e, while the lowest rates were reported in \u003cstrong\u003eItaly\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eA particularly interesting finding concerned \u003cstrong\u003egender differences\u003c\/strong\u003e in coexisting diseases.

The researchers noted that these differences were \u003cstrong\u003econsistent between countries\u003c\/strong\u003e, making them \"worthy of further investigation.\" These patterns may reflect underlying biological differences, differences in how men and women are screened or diagnosed, or social and psychological factors surrounding obesity and its treatment.\u003c\/p\u003e\n\n\u003ch2 id=\"safety\"\u003eKey Finding 4: How Safe Is Weight Loss Surgery?\u003c\/h2\u003e\n\n\u003cp\u003eFor patients considering weight loss surgery, safety is naturally a top concern. This report brings reassuring news: \u003cstrong\u003ebariatric metabolic surgery is very safe\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ereported death rate\u003c\/strong\u003e following surgery across all registries was \u003cstrong\u003e0% to 0.11%\u003c\/strong\u003e — meaning at most roughly 1 death per 1,000 operations, and in many registries zero deaths. For context, this is comparable to or better than the risk of many other common elective surgeries.\u003c\/p\u003e\n\n\u003cp\u003eThe report also looked at \u003cstrong\u003elength of hospital stay\u003c\/strong\u003e, which varied considerably between countries. For primary procedures, the median length of stay ranged from just \u003cstrong\u003e1 day in Ontario (Canada), the Netherlands, Sweden, Norway, and Michigan (USA)\u003c\/strong\u003e to \u003cstrong\u003e6 days in China\u003c\/strong\u003e. The researchers noted that these differences probably reflect \u003cstrong\u003ecultural expectations around discharge timing\u003c\/strong\u003e and the availability of community resources — not necessarily differences in medical need or quality of care. In other words, a shorter hospital stay in one country does not mean patients there are healthier or receiving worse care; it may simply reflect different norms about recovery at home.\u003c\/p\u003e\n\n\u003cp\u003eTwo other patterns emerged regarding hospital stays:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMost countries reported a length of stay that was \u003cstrong\u003eslightly higher for revisional procedures\u003c\/strong\u003e than for primary procedures — likely because revisional operations are more complex and involve scar tissue from the previous surgery.\u003c\/li\u003e\n  \u003cli\u003eThe rates of \u003cstrong\u003eunplanned readmission\u003c\/strong\u003e (being admitted back to the hospital after being discharged) were \u003cstrong\u003eslightly higher in those registries with the shortest length of stay\u003c\/strong\u003e — a finding that makes intuitive sense, since patients going home sooner have less time to be monitored in a hospital setting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 id=\"implications\"\u003eClinical Implications: What This Means for Patients\u003c\/h2\u003e\n\n\u003cp\u003eSo what does this report mean for someone considering weight loss surgery — or for someone who has already undergone a procedure?\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFirst, it confirms that weight loss surgery is a very safe option for treating severe obesity.\u003c\/strong\u003e The 0–0.11% mortality rate is an important number for patients and their families to understand when weighing the risks of surgery against the very real risks of untreated severe obesity, which include heart disease, stroke, diabetes complications, and certain cancers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSecond, the report provides a detailed picture of the \"typical\" bariatric surgery patient.\u003c\/strong\u003e The typical patient is female, has a starting BMI of roughly 40–45 kg\/m², and is between the age of 25 and 44 depending on the country. However, the wide ranges show that weight loss surgery is being used successfully across a broad spectrum of ages and body sizes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThird, the findings suggest that surgeons are increasingly tailoring procedures to individual patients.\u003c\/strong\u003e The growing variety of procedures — including \"other\" and revisional operations — means that patients who have not succeeded with one approach may have additional options. The increasing use of robotic techniques also reflects ongoing innovation in the field.\u003c\/p\u003e\n\n\u003cp\u003eFinally, the gender differences in coexisting diseases highlight the importance of \u003cstrong\u003ecomprehensive preoperative screening\u003c\/strong\u003e. Male patients should be carefully evaluated for diabetes, sleep apnea, abnormal cholesterol, and high blood pressure, while female patients should be screened for depression. This personalized approach to preparing for surgery can improve outcomes for everyone.\u003c\/p\u003e\n\n\u003ch2 id=\"limitations\"\u003eLimitations: What This Report Couldn't Prove\u003c\/h2\u003e\n\n\u003cp\u003eIt is just as important to understand what this report cannot tell us as what it can.

This is comparable to or better than many other common elective surgeries, making weight loss surgery remarkably safe.\u003c\/p\u003e\n\u003ch3\u003eWho typically undergoes weight loss surgery?\u003c\/h3\u003e\n\u003cp\u003eWorldwide, the majority of patients having weight loss surgery are female. Median starting BMI is usually 40-45 kg\/m², which falls in the severe obesity range. Patient age varies notably by country, from a median of 25 years in Kuwait to 44 years in the Netherlands, Italy, and New Zealand.\u003c\/p\u003e\n\u003ch3\u003eWhat is the most common weight loss operation?\u003c\/h3\u003e\n\u003cp\u003eSleeve gastrectomy is the most frequently performed primary weight loss procedure worldwide, followed by Roux-en-Y gastric bypass. These two operations are the backbone of modern bariatric surgery. Surgeons are also increasingly using other procedures, especially for revisional surgeries, and robotic techniques are becoming more common.\u003c\/p\u003e\n\u003ch3\u003eWhich obesity-related diseases are most common in surgery patients?\u003c\/h3\u003e\n\u003cp\u003eType 2 diabetes is the most frequently reported obesity-related disease among patients undergoing weight loss surgery. Males are more likely to have diabetes, obstructive sleep apnea, dyslipidemia, and hypertension, while females are more likely to report depression. These differences were consistent across countries and warrant further investigation.\u003c\/p\u003e\n\u003ch3\u003eHow long is the hospital stay after weight loss surgery?\u003c\/h3\u003e\n\u003cp\u003eThe median hospital stay varies by country, ranging from 1 day in several countries including Canada, the Netherlands, Sweden, and Norway, to 6 days in China. Shorter stays likely reflect different cultural norms and resources, not worse care. Revisional procedures tend to have slightly longer stays than primary procedures.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between primary and revisional weight loss surgery?\u003c\/h3\u003e\n\u003cp\u003ePrimary surgery is a patient's first weight loss operation, while revisional surgery is a second operation to correct or revise a previous one. Revisional procedures are often more complex because they involve scar tissue, which is why hospital stays tend to be slightly longer for these cases.\u003c\/p\u003e\n\u003ch3\u003eWhy does it matter if a weight loss program participates in a registry?\u003c\/h3\u003e\n\u003cp\u003eRegistry participation shows a program is committed to quality assurance and transparency. It means the program tracks its outcomes and compares them to national and international benchmarks. For patients, seeking care at a program that participates in a national or regional registry can be a marker of continuous quality improvement.\u003c\/p\u003e\n\u003c!-- ddn:faq:end --\u003e\n\n\u003ch2 id=\"source\"\u003eSource Information\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eOriginal article:\u003c\/strong\u003e Seventh IFSO Global Registry Report 2022\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAuthors\/Contributors:\u003c\/strong\u003e Wendy A.
