Diabetes and weight-loss drugs like GLP-1 agonists can lower blood pressure by about 10 points on average, and this happens even before much weight is lost.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Establish causal effects of GLP-1RAs on blood pressure.
A double-blind RCT of 1,200 adults with type 2 diabetes and hypertension, randomized to semaglutide 1.0 mg/week vs placebo for 24 weeks, with 24-hour ambulatory BP as primary endpoint, blinded assessment.
Provide pooled estimate of BP reduction across all GLP-1RA trials.
A meta-analysis of all placebo-controlled RCTs of GLP-1RAs ≥12 weeks, extracting mean change in systolic and diastolic BP from ambulatory monitoring, using random-effects model.
Assess long-term BP control in real-world users.
A prospective cohort of 7,000 patients with diabetes starting GLP-1RAs, with office and ambulatory BP measured annually over 5 years.
Estimate average BP among current users.
A cross-sectional analysis of 10,000 patients on GLP-1RAs, extracting latest BP readings from EHRs, adjusting for age, sex, and antihypertensive medications.
Interpret BP findings and clinical relevance.
A narrative review discussing mechanisms and clinical implications of GLP-1RA effects on BP, summarizing trial data.
