GLP-1 and peripheral arterial disease — looking for input

Vitamin deficiency cascade with cardiovascular risk: after 6+ months of reduced food intake, I developed a subtle but important pattern: low B12 →…

Thank you — that is the clearest version of this I have read, and I have read a lot of them.

Clinical perspective, offered as context rather than as advice.

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.

SUSTAIN-6 was the first CVOT to show cardiovascular benefit with semaglutide, relevant to cardiovascular risk.

6 month update on cardiovascular risk: down 64 lbs, off blood pressure meds, A1C normalized. Genuinely life-changing.

SELECT is the trial that changed the framing of this class, because it was an outcome trial rather than a weight trial: about a 20% relative reduction…

...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.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful.
