Medical Research on Diabetes and Obesity Treatments

New observational studies suggest GLP‑1 diabetes and obesity drugs are associated with higher rates of fractures, osteoporosis and gout in older adults. Separately, a BMJ analysis of more than 600,000 U.S. veterans found GLP‑1 initiators had roughly a 15–20% lower risk of developing substance use disorders and, among those with prior SUD, about 25–50% lower risk of drug‑related emergency visits, hospitalizations, overdoses, suicide‑related events and death; investigators propose a shared "biologic signal," but outside experts caution that these are observational findings and randomized trials of GLP‑1s for addiction are underway.
