Lp(a) and cardiovascular risk: a nuance that matters. Unlike most lipid markers, Lp(a) is 90%+ genetically determined and doesn't really change with weight loss or GLP-1 therapy.
My Lp(a) has remained at 56 nmol/L across all time points. If yours is elevated (>50 nmol/L), you need additional risk mitigation strategies regardless of your GLP-1 response. Don't assume your medication is covering all cardiovascular risk factors.

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.

Saving this. It is the first explanation that did not require me to already understand it. I will report back once I have actually tried it.

Dizziness and cardiovascular risk: I was lightheaded for the first 3 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.

Mine went the same way, slower.
