Hey Karl. First off, respect—that’s a solid blood pressure, and dropping 31 pounds is no small thing. You’re clearly putting in the work, and at 4.8 cm, every little bit helps when it comes to reducing stress on your aorta.

I had a Type A dissection back in 2015 and needed emergency open-heart surgery with a Dacron graft. So yeah, I take this seriously and I get where you're coming from. After my surgery, I went deep into learning what helps and what doesn’t. Here's the deal: there’s really no supplement or herb that’s been proven to shrink an aneurysm. I’ve heard people talk about turmeric, hawthorn, nattokinase, magnesium, etc.—and while some of those might support general vascular health, none of them are a magic bullet.

The big three are: keep blood pressure low (you’re already nailing that), avoid big blood pressure spikes (like heavy lifting, straining, or holding your breath), and get regular imaging to track size. Also, hydration matters more than people think. Dehydration can cause subtle spikes in blood pressure that fly under the radar.

I take meds now, and I’m okay with that. I’ve learned not to fight the tools that help me stay alive. But lifestyle? That’s huge too—and you’re doing a lot right. Keep walking, stay steady with the low-carb plan if it’s working for you, and just be cautious about anyone promising that an aneurysm can shrink with supplements alone. If it were that simple, none of us would be here. You’re on the right track. Keep at it. Peace.
