I read this differently from mike.trainer_LA, 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.

Prescribed on cardiovascular grounds rather than for weight, and almost everything written for patients assumes the opposite.

6 month update on cardiovascular risk: down 56 lbs, off blood pressure meds, A1C normalized. Genuinely life-changing.

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.

One thing that is still open after gary_naperville’s answer:

Did your prescriber agree with that reading, and if not what was their objection?

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.
