Hi much has been written about your question in the forum. Your aneurysm is in the larger side, it usually means you get more frequent checks and depending on several variables (your body size, family history, general health, etc) maybe even start planning for repair. Seeing a surgeon is a must at that size, the surgeon will evaluate all the variables above and give you guidance. You may want to consult more than one, look for one with thousands of these surgeries done, major medical center with all the capabilities.
In the mean time your top priority is maintaining BP under control, high BP even for short spikes is the worst enemy of an aneurysm. If you don’t have a cardiologist look for one who specializes in aortic diseases it makes a huge difference, hopefully he/she will maintain communication with the surgeon. Remember the surgeon will stop seeing you after surgery, the cardiologist will follow you for life.
The exertion comment is related to BP, any exercise that leads you into an effort that makes you hold your breath or grunt raises your BP to really high levels for this seconds, and as I mentioned even short spikes are dangerous.
Keep yourself health eat well, exercise but minding the limitations, you want your body at its best if/when you have surgery.
I had a 5.2cm ascending aortic aneurysm that was repaired 6 years ago, I was in good health and it went as smooth as it could have gone. 6 years on I live a very active normal life. I get checked every year by my cardiologist.
The Dr said if you “want” to talk to a surgeon, the answer is yes and the sooner the better, same with a cardiologist.
You know you have it and can take care of it, plan and make arrangements, not everyone gets that opportunity.
All the best
