Heart rate increase on GLP-1 — 6 month update

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.

My reason for being on this is cardiovascular rather than cosmetic, which puts me in a small minority in most of these threads.

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.

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.

Following on from KetoKyle — and this may be the naive question:

Was that from a primary source or from a summary of one?

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.
