I lied at MEPS. Will they go back and look through my medical records?

I have talked to just about all my military friends and talk over a few beers about how we made it through MEPS. 99% lied about a parking ticket or a broken bone. A while back there was a Command Sergeant Major who after 25 years of service during his retirement process to get him his DD214 some one had realized that he had stolen his twin brother his identity to get in. Naturally he lost all benefits after well earned awards and benefits. BUT HE LIED. at least im sure he had fun jumping out of planes and collecting a paycheck (one check that he is not gonna get as a retiree) with you medical past. If you die ARMY will not pay life insurance if you die of the one condition(s) in question. Nor VA most likely will not compensate you for the same. But if you want to serve. Do what your heart feels.

Technically they cant without your consent but on that note it's possible you will get denied on that basis.

I had asthma and a bad back. My doctor offered to send a letter to the draft board. I said no and enlisted. MACV SOG, CIA and retired Homeland.

You have already violated the Army values. Integrity is an integral aspect of serving! If you are not willing to show it in the beginning, chances are you won’t show it during your career. Personally, I wouldn’t want you serving next to me, especially, having to depend on your integrity! The willingness to serve is admirable, however, MEPS is in place for a reason. As it has been mentioned throughout this thread, your health matters tremendously in mission readiness and capability. My advice, fix this issue before it’s too late! Come clean BEFORE you ship out, if not, just know that you WILL be reported and the penalties under UCMJ will be severe!

You were 6 buddy...but don't bring this sort of thing up in a public forum.

You were 6 when you were told you had a heart murmur, and could not be expected to know that when you enlisted, easily forgotten and nobody would know you had "lied" I suppose by omission, and who could prove you were told? Many parents wouldn't tell their kid something like that..

You weren't six when you lied about it. Or when you confessed to your actual crime of lying on an official document on Rallypoint.

The real answer to your actual initial question is, paraphrasing someone else about this public forum--they will now.

Now that it's two years later and RP decided that now would be a good time for me to see this, I am really curious how this situation panned out.

Is it the Doctor at MEPS that is sending to a Cardiologist? If they do say you have a I don't think that they ca say for sure that you had it as a child and unless the Cardiologist sees something different you will probably be good to go.

Yes, they can find your medical records and you will be booted out in Basic/Boot Camp (if you make it).
We had one guy who lied about a broken leg. He was kicked out of Basic after 6 weeks. Another failed to mention he had received an undesirable (now OTH) discharge from the Navy. He disappeared after week 5.

Good luck in life, dude. You're gonna need it. Not because of the murmur. But because of your poor decision to lie about it.
