I want to bring up the cardiovascular angle on cardiovascular risk.
The SELECT trial demonstrated a 20% reduction in MACE with semaglutide 2.4mg[1]. This is practice-changing because the CV benefit appears to be independent of the degree of weight loss — suggesting direct vascular and anti-inflammatory mechanisms.
For cardiovascular risk, this means we need to think beyond the primary outcome and consider the cardiovascular implications. The all-cause mortality reduction (HR 0.81) is the most clinically meaningful signal.

Mendelian randomization evidence supporting GLP-1 pathway modulation for cardiovascular risk: genetic variants in the GLP1R gene region associated with lower BMI also show associations with reduced cardiovascular risk, confirming a causal pathway[1].
This "natural experiment" (people born with genetically higher GLP-1 signaling being leaner and healthier) provides orthogonal evidence supporting the pharmacological approach. When genetic epidemiology, clinical trials, and mechanistic studies all converge, confidence in the therapeutic approach is high.

A narrower follow-up, since the general answer is now clear:

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.

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