GLP-1s Raise Hypotension Events to 10.2% at 6 Months in Patients on 2+ BP Drugs

Summary
42,262 patients taking at least two antihypertensive classes saw hypotension-related events rise from 8.7% to 10.2% within 6 months of starting a GLP-1, according to research presented at ENDO 2026.
Older adults and diabetes patients appeared most vulnerable: people 65 or older accounted for 53% of events but 37% of the cohort, while type 2 diabetes patients made up 75% of events versus 63% overall.
Researchers said weight loss likely contributed to lower blood pressure, but secondary analyses suggested it did not fully explain the increase; dehydration, direct vascular effects and sodium excretion were also cited as possible mechanisms.
The study was retrospective and observational, and an outside specialist said the broad composite endpoint, modest absolute differences and loss of significance by 24 months argue for vigilance rather than alarm.
Clinicians were urged to monitor blood pressure closely after starting GLP-1s in patients on multiple antihypertensives and consider reducing those drugs proactively, especially for older adults and people with type 2 diabetes.
