U.S. bariatric surgery rates drop significantly amid GLP-1 surge

The number of metabolic and bariatric surgery procedures in the United States dropped below 200,000 in 2024 for the first time since 2020, a more than 20% decline from the prior year, according to new research presented today at the annual scientific meeting of the American Society for Metabolic and Bariatric Surgery.

Bariatric surgery improves outcomes for patients with obesity and chronic kidney disease

Metabolic and bariatric surgery, also known as weight-loss surgery, dramatically improves outcomes for patients with obesity and chronic kidney disease (CKD), significantly reducing the risk of kidney failure, major cardiovascular events and death, according to new research presented here today at the annual meeting of the American Society for Metabolic and Bariatric Surgery.

GLP-1 use surges as surgery rates drop for severe obesity

Drawing on electronic health records from nearly 20 million patients with severe obesity, researchers from University of California San Diego find that GLP-1 prescriptions have grown exponentially -- from less than 4,600 prescriptions in 2018 to more than 1.4 million in 2025 -- according to a new real-world analysis presented today at the annual scientific meeting of the American Society for Metabolic and Bariatric Surgery.

Bariatric surgery costs significantly less than GLP-1 drugs over two years

A new real-world analysis of more than 90,000 patients with obesity and type 2 diabetes finds metabolic and bariatric surgery is costs significantly less than weekly injections of GLP-1 drugs over a two-year period, according to a new research presented today at the annual scientific meeting of the American Society for Metabolic and Bariatric Surgery.

Study reveals epigenetic adaptation of beta cells across lifespan and disease

As people age, most maintain normal blood sugar even as insulin resistance tends to rise. New research suggests that pancreatic beta cells help meet this demand through gradual epigenetic changes in regulatory regions of the genome that support beta-cell identity and function.

Mapping brain circuits helps identify the causes of psychiatric symptoms

If a small stroke in one corner of the brain can tip a previously healthy person into mania or set off obsessions and compulsions where none existed before, then the circuit connected to that lesion is telling us something rare in psychiatry.

GLP-1 drugs combined with surgery yield superior weight loss results

People who begin obesity treatment with glucagon-like peptide-1 receptor agonists (GLP-1s) and then undergo metabolic and bariatric surgery achieve substantially greater weight loss than with the medications alone, according to new research presented today at the annual meeting of the American Society for Metabolic and Bariatric Surgery.

A more accurate tool for assessing Arsenic toxicity

Public health experts estimate that more than 200 million people worldwide are exposed to arsenic through contaminated drinking water. Scientists know long-term exposure to arsenic is associated with increased risk of chronic illnesses like cancer and cardiovascular disease, but there hasn't been a reliable way to track these exposures and fully understand their effects on the body and the mechanisms behind them.
