Dr.GutHealth said:6 month update on cardiovascular risk: down 46 lbs, off blood pressure meds, A1C normalized.
I read this differently from Dr.GutHealth, on substance rather than tone. 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.

NNT calculation for cardiovascular risk clinical endpoints: NNT = 1/ARR (absolute risk reduction).
From SELECT trial: MACE at 39 months — 6.5% semaglutide vs 8.0% placebo. ARR = 1.5%. NNT = 67 over 3.3 years.
Compare to established therapies:
| Intervention | NNT | Timeframe |
|---|---|---|
| Semaglutide (MACE) | 67 | 3.3 years |
| Statins primary prevention (MI) | ~100 | 5 years |
| Aspirin secondary prevention | ~77 | 2 years |
These NNTs are clinically meaningful and comparable to accepted cardiovascular interventions.

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

Vitamin deficiency cascade with cardiovascular risk: after 6+ months of reduced food intake, I developed a subtle but important pattern: low B12 → elevated homocysteine → increased cardiovascular risk marker.
The connection: B12 is a cofactor for homocysteine metabolism. Without adequate B12, homocysteine accumulates. This is ironic — taking a CV-protective medication while developing a CV risk factor from reduced nutrition.
Solution: comprehensive vitamin supplementation and regular lab monitoring. Don't let the medication's benefits be undermined by nutritional deficiencies.
