Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The "earlier than weight loss explains" argument is weaker than this thread makes it sound. Blood pressure and inflammatory markers move fast and are downstream of early weight loss, so the mechanism is not as cleanly separable as the summaries imply.
Dr.DermMIA said:Prescribed on cardiovascular grounds rather than for weight, and almost everything written for patients assumes the opposite.
Dr.DermMIA said:...we're creating a generation dependent on cardiovascular risk...
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.

Anti-inflammatory mechanisms of GLP-1 agonists and cardiovascular risk: beyond weight loss, GLP-1R activation directly suppresses NF-κB signaling, reduces NLRP3 inflammasome activation, and decreases monocyte/macrophage adhesion to endothelium[1].
Clinical correlates: hsCRP reduction of 30-60% (consistently seen across trials), reduced carotid intima-media thickness, and decreased coronary plaque inflammation on PET imaging.
These anti-inflammatory effects likely contribute to the cardiovascular benefit seen in SELECT — and may explain benefits beyond what weight loss alone would predict.

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off losartan 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.
