Thank you — that is the clearest version of this I have read, and I have read a lot of them. Printing the relevant bit and taking it with me.
From the other side of the consultation, briefly.
SUSTAIN-6 was the first CVOT to show cardiovascular benefit with semaglutide, relevant to cardiovascular risk. In 3,297 T2DM patients with high CV risk: MACE HR 0.74 (95% CI 0.58-0.95, p=0.02)[1].
Notable: the retinopathy signal in SUSTAIN-6 (HR 1.76) was subsequently attributed to rapid A1C reduction in patients with pre-existing retinopathy — not a direct drug effect. This has been confirmed in longer-term follow-up studies.

I understand the skepticism — we've all seen "miracle" weight loss solutions come and go. But consider what makes GLP-1 agonists different:
- Phase 3 RCTs with thousands of participants (not 20-person pilot studies)
- Published in NEJM, JAMA, Lancet (not press releases)
- Replicated across multiple independent research groups
- Proven cardiovascular and renal benefits beyond weight loss
- Biological mechanism fully characterized at the receptor level
This isn't a fad — it's a new drug class supported by the highest level of clinical evidence. The comparison to past fads is understandable but inappropriate.

Dizziness and cardiovascular risk: I was lightheaded for the first 2 weeks. Root cause was a combination of reduced caloric intake and mild dehydration.
Fix: minimum 80-100oz water daily, don't skip meals even if you're not hungry (eat small protein-rich snacks), and stand up slowly from sitting/lying positions. Also check your blood pressure — GLP-1-induced weight loss can make BP meds too strong, requiring dose reduction.
Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. Carry on.
