A Johns Hopkins study found GLP-1 users face increased dementia risk after a decade, possibly due to longer lifespan. A separate JCI review found GLP-1 drugs show neuroprotective signals in preclinical studies but consistent cognitive benefits in humans remain unproven.
Two retrospective studies in type 2 diabetes patients with unruptured intracranial aneurysms linked GLP-1RAs to lower non-traumatic subarachnoid haemorrhage risk. One study also showed lower all-cause mortality over five years.
GLP-1 drugs are expanding in 2026 with oral semaglutide for weight management, rising patient use and broader commercialization. A study also found a modest increase in erectile dysfunction risk among men with Type 2 diabetes starting GLP-1 medicines, though the association weakened after stricter adjustment.
Boots has launched an in-store weight loss service across 17 UK locations, offering face-to-face consultations for weight-loss injections like Wegovy and Mounjaro. The service includes a 10-week free weight loss programme and 12-month aftercare, with prices starting at £99.97 for Wegovy. This marks the first high street pharmacy to provide such in-person weight loss treatment consultations.
A study of over 600,000 patients reveals GLP-1 drugs may reduce addiction across multiple substances, with 50% fewer substance-related deaths and significant reductions in overdoses and hospitalizations. The drugs work by dampening dopamine signaling in brain reward centers. Researchers are exploring broader applications for these medications beyond diabetes and obesity treatment.
The FDA has shifted from regulatory ambiguity to coordinated enforcement against compounded oral semaglutide, culminating in a 2026 announcement of intent to take action against non-approved GLP-1 drugs. Hims & Hers Health's 2024 oral semaglutide offering marked the beginning of a broader regulatory reckoning that saw manufacturer pressure, formal shortage declarations, and warning letters targeting compounding practices.
Multiple Indian pharmaceutical companies including Zydus, Glenmark, Dr. Reddy's, and Alkem have launched semaglutide versions following patent expiry, dramatically reducing prices and expanding access. Companies are competing on both price and innovative delivery systems, with monthly therapy costs now ranging from Rs 1,300 to Rs 4,200. This development could significantly impact diabetes and obesity treatment in India, where over 100 million people live with diabetes.
Novo Nordisk received FDA approval for a 7.2-mg semaglutide dose marketed as Wegovy HD for adult patients with obesity who have tolerated the standard 2.4-mg dose. The approval came through the FDA's new Commissioner's National Priority Voucher pilot program.
GLP-1 receptor agonists like semaglutide and tirzepatide help regulate appetite and improve satiety for medical weight loss. Clinical studies show patients can lose an average of 15% of body weight with these treatments. These medications are suitable for individuals with BMI of 27+ with weight-related conditions or BMI of 30+ regardless of other conditions.
New clinical evidence demonstrates that combining SGLT2 inhibitors with GLP-1 receptor agonists provides additive benefits for type 2 diabetes patients, while machine learning tools help personalize therapy selection.
