Is surgery better than dieting for weight loss outcomes?

New research has uncovered an association between bariatric surgery and lower death rates.
According to data from the Centers for Disease Control and Prevention (CDC), over a third of adults in the United States lives with obesity. This is particularly worrisome as the condition is also linked to other negative health outcomes, including diabetes, heart disease, and certain types of cancer. The most common ways to manage excess weight are dieting, physical exercise, weight loss drugs, and bariatric, or weight loss, surgery. Individuals aiming to get back into shape may opt for one or a combination of these treatments, depending on what choices are most suitable for them. Bariatric surgery is usually offered to individuals diagnosed with "severe obesity," which is defined as a having a body mass index (BMI) of over 35. This surgery type aims to make the stomach smaller, so that a person's appetite — as well as the amount of food that they can ingest — is reduced. Types of bariatric surgery include:
Recently, Orna Reges, Ph.D., and others from Clalit Health Services in Tel Aviv, Israel, conducted a study that explored which types of weight loss strategy and procedures are associated with a lower risk of all-cause mortality. The findings of their study are published in the Journal of the American Medical Association. Surgery versus nonsurgical managementReges and her team conducted a retrospective cohort study that involved 8,385 people diagnosed with obesity, all of whom had had some type of weight loss surgery (either laparoscopic banding, gastric bypass, or gastrectomy) between 2005 and 2014, and 25,155 people who followed alternative obesity management programs, as advised by their physicians. Obesity management interventions included counseling sessions that targeted diet and working to improve eating behaviors. The participants in the two groups were matched as closely as possible for age — with a median age of 46 — and biological sex. The final follow-up date for all of the participants was December 31, 2015. After analyzing the data obtained from these cohorts over a period of approximately 4.5 years, Reges and colleagues found that the individuals diagnosed with obesity who had undergone bariatric surgery had a lower rate of all-cause mortality than those who had opted for nonsurgical management. The researchers argue that their study is relevant in the context in which much research has been conducted about the short-term outcomes of weight loss surgery, but information about its long-term outcomes is limited. Specifically, they were interested in gathering more data about the associations between this type of intervention and all-cause mortality rates. This kind of information, they say, had not been reliably available before, because previous studies were unable to compare the data for patients of bariatric surgery with those of individuals who had opted for nonsurgical interventions. Reges and her team, however, warn that their study is observational, so it is difficult to infer a direct causal relationship between bariatric surgery and lower death rates. The findings, they say, could be influenced by a range of different factors that the researchers were unable to control. Other limitations include "group imbalance" created by matching the participants based on their age, sex, BMI, and an existing diagnosis of diabetes. Nevertheless, the authors conclude that their study will enrich the existing resources addressing the health outcomes of various obesity treatments. They write:
