The FDA has not approved GLP-1 drugs for anti-aging use, and the long-term safety of GLP-1s in healthy, non-metabolic-disease populations has not been studied Who Faces the Greatest Risk from Premature Use The population most at risk from the commercial enthusiasm outpacing the evidence includes: Healthy adults without diabetes or obesity who are prescribed compounded semaglutide from online or wellness-clinic sources outside standard medical supervision Patients who stop medications for established conditions (diabetes, cardiovascular disease) to substitute GLP-1 drugs on the belief they offer broader protection Older adults with kidney disease or motility disorders, for whom the FDA's added warnings about acute kidney injury and intestinal obstruction are directly relevant Patients who purchase compounded semaglutide which has not been reviewed by the FDA for safety, quality, or efficacy at doses not established in clinical trials Symptoms and Warning Signs to Watch For Patients currently prescribed GLP-1 drugs whether for approved indications or off-label should be aware of the following warning signs that warrant immediate medical evaluation: Severe or persistent nausea, vomiting, or abdominal pain (may indicate pancreatitis or intestinal obstruction) Inability to have a bowel movement for several days (may indicate ileus or fecal impaction) Decreased urine output, swelling, or unusual fatigue (may indicate acute kidney injury) Vision changes particularly sudden vision loss in one eye (rare but flagged in labeling as a serious adverse event) The FDA's October 2025 label update for Ozempic specifically added warnings about ileus, intestinal obstruction, and acute kidney injury as adverse reactions that have been reported post-marketing
