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.

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.

Study highlights breakthrough in overcoming diminishing returns of sequential IBD therapies

For patients with Crohn's disease or ulcerative colitis who have exhausted other treatment options, a new combination therapy is showing results that offer hope for one of medicine's most treatment-resistant populations, according to findings from two studies to be presented today at Digestive Disease Week® (DDW) 2026.

Brain pathways shape distinct itch responses in the face and body

In a new study, researchers from North Carolina State University show that itch sensations in the face are perceived differently from those in the body due to differences in signaling between trigeminal (located in the brain) and spinal pain pathways.

NIH awards $3.9 million grant to develop a non-opioid pain treatment

The National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health (NIH), has awarded a $3.9 million grant to a multi-institutional team led by scientists at Sanford Burnham Prebys Medical Discovery Institute to develop a non-opioid pain therapeutic and advance it into a Phase 1 clinical trial.

Randomized controlled trial validates total hip arthroplasty for improving functional capacity

Total hip arthroplasty leads to the best outcomes in the treatment of moderate-to-severe hip osteoarthritis, according to a new study by the University of Eastern Finland and Kuopio University Hospital. During a one-year follow-up, surgery combined with conservative treatment was found to relieve pain and improve functional capacity and quality of life more effectively than conservative treatment alone, which was based on an exercise program.
