GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Methylene blue enhances hair follicle stem cell regeneration under stress

A new research paper was published in Volume 18 of Aging-US on May 5, 2026, titled "Methylene blue protects hair follicle stem cells from oxidative and metabolic stress to enhance hair regeneration."

Endoscopic sleeve gastroplasty outperforms oral semaglutide in short-term weight loss

A comparative study, presented at ESGE Days 2026, has found that endoscopic sleeve gastroplasty (ESG) is associated with significantly greater short-term weight loss than oral semaglutide in adults with obesity.

GLP-1 weight loss medications linked to significant drop in asthma flares

New research presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) shows the use of the new GLP-1 class of obesity drugs in people with asthma is associated with a 26 % fall in the number of asthma exacerbations and a 14% drop in use of asthma inhaler reliever use. The study is by Simon Høj and Dr Kjell Erik Julius Håkansson, Copenhagen University Hospital, Copenhagen, Denmark and colleagues.

New obesity medications offer a potent tool for combating hypertension

A meta-analysis of 32 studies and 43,618 adults presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) shows that use of new classes of obesity drugs for weight loss is associated with a clinically relevant drop in blood pressure (BP): a 0.34 mmHg reduction in systolic BP per 1\% weight loss.

Semaglutide significantly reduces obesity in treatment-resistant young adults

A weekly dose of semaglutide (2.4 mg) leads to a clinically significant reduction in body mass index (BMI) and related health outcomes in young adults with severe obesity who are treatment resistant following hospital-based non-pharmacological obesity care during childhood, according to a randomized controlled trial being presented at this year's European Congress on Obesity (ECO) in Istanbul, Turkey (12-15 May).

GLP-1 obesity drugs mainly reduce fat while preserving muscle mass

New research to be presented at the European Congress on Obesity (ECO2026) in Istanbul, Turkey (12–15 May) shows that following treatment with GLP-1 drugs for obesity, most weight loss is fat mass (80–85%) and relative muscle mass is preserved.

Once-daily orforglipron helps preserve weight loss after semaglutide or tirzepatide

Oral orforglipron helped adults maintain clinically meaningful weight loss after prior injectable tirzepatide or semaglutide therapy. The phase 3b ATTAIN-MAINTAIN trial suggests switching to once-daily oral therapy may help reduce weight regain when injectable treatment is discontinued.

Large human islet study reveals new insights into diabetes risk

Diabetes is the most common and serious chronic disease worldwide, characterized by insufficient insulin to maintain proper blood glucose levels.

Could GLP-1 drugs help breast cancer patients live longer?

A large retrospective cohort study of adult female breast cancer patients found that GLP-1 receptor agonist use was associated with better all-cause survival and recurrence-free survival in patients with obesity or type 2 diabetes. The strongest associations were seen versus non-use in obesity and versus insulin or metformin in type 2 diabetes, while comparisons with SGLT2 inhibitors were less consistent and require further study.

Two leading heart risk tools pass a major global test

A multinational Nature Medicine validation study found that PREVENT and SCORE2 cardiovascular risk equations performed generally well across 6.4 million people from observational cohorts and randomized trials. The findings support broader use of these tools for CVD risk stratification, while highlighting the need for local calibration and more validation in underrepresented regions.

Semaglutide shows sustained weight loss benefits in older adults

A new analysis of the STEP trails carried out by semaglutide manufacturer Novo Nordisk has analysed various trials to show the safety and efficacy of the obesity drug semaglutide in older adults (over 65 years), and found similar efficacy and safety as in the general trial populations .

Daily orforglipron treatment reduces weight and blood sugar in seniors

A new analysis to be presented at this year's European Congress on Obesity (ECO 2026, Istanbul, Turkey, 12-15 May) examined daily oral orforglipron treatment for the treatment of obesity, with or without diabetes, in users aged 65 years and over, with results and a safety profile similar to that seen in the ATTAIN clinical trial programme population.

Greater weight loss from GLP-1 drugs lowers health complication risk

New research to be presented at this year's European Congress on Obesity (ECO 2026, Istanbul, Turkey, 12-15 May) shows that, following treatment for obesity or diabetes or both using incretin-based drugs, losing more weight versus less weight, and losing a little weight versus gaining weight, both lead to relatively lower risk of obesity-related conditions.

Liver fat may disrupt post-meal glucagon control in early type 2 diabetes

Researchers found that MASLD, rather than type 2 diabetes alone, was linked to higher fasting glucagon levels in adults with newly diagnosed diabetes and matched controls. In people with early type 2 diabetes, higher liver fat was specifically associated with exaggerated early post-meal glucagon responses, independent of insulin sensitivity, visceral fat, amino acids, or NEFAs.

People judge GLP-1 users more harshly than dieters

Stigma surrounding GLP-1 weight loss treatments reveals societal biases, impacting individuals' mental health and the effectiveness of obesity interventions.

Bariatric surgery outperforms GLP-1 medications for obesity disease remission

Metabolic and bariatric surgery delivers significantly greater weight loss and higher rates of obesity-related disease remission than glucagon-like peptide-1 receptor agonists (GLP-1s), according to one of the largest and most comprehensive real-world comparisons of the two treatments.

Popular GLP-1 drugs significantly reduce major cardiovascular events,

Researchers evaluate the long-term cardiovascular safety and efficacy of GLP-1RAs in high-risk populations.

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.

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.
