My dad had a heart attack and now I am terrified - will GLP-1 help? — looking for input

6 month update on cardiovascular risk: down 51 lbs, off blood pressure meds, A1C normalized.

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.

This answered a question I did not know how to ask.

From the other side of the consultation, briefly.

This is a fair point, and I think intellectual honesty requires acknowledging it. GLP-1 agonists in their current form have ~8-10 years of human exposure data. That's not nothing, but it's not 30+ years either.

However: the risk-benefit calculation should also consider the KNOWN long-term effects of untreated obesity — diabetes, cardiovascular disease, cancer, joint destruction, reduced lifespan by 5-10 years.

Uncertainty about GLP-1 long-term safety vs certainty about obesity consequences. The calculus seems clear to me, but reasonable people can disagree.

Same pattern here, and in the same order. Nothing to add that would improve it.

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.
