From the other side of the consultation, briefly.

This is a fair point, and I think intellectual honesty requires acknowledging it. GLP-1 agonists in their current form have ~8-10 years of human exposure data. That's not nothing, but it's not 30+ years either.
However: the risk-benefit calculation should also consider the KNOWN long-term effects of untreated obesity — diabetes, cardiovascular disease, cancer, joint destruction, reduced lifespan by 5-10 years.
Uncertainty about GLP-1 long-term safety vs certainty about obesity consequences. The calculus seems clear to me, but reasonable people can disagree.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.

I understand the concern, but consider this analogy: are we "creating a generation dependent on" blood pressure medication? Cholesterol medication? Thyroid medication?
Obesity is a chronic disease with biological drivers. Treating it with medication is no different from treating any other chronic condition. The "dependency" framing implies weakness or moral failure — neither of which is accurate.
If ongoing medication is what keeps someone healthy, that's successful treatment, not dependency.

Mendelian randomization evidence supporting GLP-1 pathway modulation for cardiovascular risk: genetic variants in the GLP1R gene region associated with lower BMI also show associations with reduced cardiovascular risk, confirming a causal pathway[1].
This "natural experiment" (people born with genetically higher GLP-1 signaling being leaner and healthier) provides orthogonal evidence supporting the pharmacological approach. When genetic epidemiology, clinical trials, and mechanistic studies all converge, confidence in the therapeutic approach is high.

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off metoprolol entirely! My cardiologist is thrilled.
If you're on BP meds and losing weight on a GLP-1, monitor your BP at home regularly. Hypotension symptoms (dizziness, lightheadedness when standing) mean your BP meds may need reduction. Don't wait for your next scheduled appointment — call your doctor.
