Thank you for spelling out the reasoning rather than just the conclusion. Adding it to my notes with a link back to this thread.
Clinical perspective, offered as context rather than as advice.
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.

Adding a me-too, because a thread of one person's experience is not much use. I had assumed I was the exception until I read this.

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

Metabolic syndrome resolution on cardiovascular risk: I went from meeting 3 of 5 diagnostic criteria to meeting ZERO after 14 months of treatment.
The 5 criteria (and my journey):
- Waist circumference: 53" → 37" ✅ Resolved
- Triglycerides: 231 → 101 ✅ Resolved
- HDL: 37 → 53 ✅ Resolved
- Blood pressure: 141/97 → 119/73 ✅ Resolved
- Fasting glucose: 126 → 89 ✅ Resolved
Metabolic syndrome reversal is, in my view, the most medically significant outcome of GLP-1 therapy.
