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

Sigh

They will now.

They will now.

Play dumb and act like you thought it was healed. The my day all that crap as a scare tactic. But everyone lies about something. The military wouldn’t even exist if everyone was honest about past medical conditions. There’s so many stipulations that they can find a reason to DQ any and everybody if they wanted. Pick a good story and stick to it. Good luck.

Probably not a smart move.Being a former Infantryman I can attest that they have legal authority to review your entire history if someone finds out you lied about it.Plus in this day and age it was probably not the greatest idea to start off by saying you lied.Thats admission and of the MEPS station gets wind of it you can be in what we lovingly called "Deep shit"
You said you had to see a cardiologist so do that and see what they determine.But the longer you perpetuate the lie the more likely your going to slip up at a crucial point,and the military does not take kindly to being intentionally lied to.God speed and hope everything works out for you.

Well your recruiter should have advised you to be honest at your meps physical. I did 13 years in recruiting command and had many deps make it through the meps med process with a medical consultation and waivers. But lies will never help you in the long run

They either let you in or won't. Not like they are going court martial you and locm you away.

However the NCIS agent in the office next door to me wants to know your user name, and home city.

You should delete this

I would not worry about it. As a medical professional mentioned in the comments, it's easy to make mis-statements at MEPS. When I was going through the entry process, a routine medical question was 'Do you have any birth defects?' I said 'no' because, at the time, I wasn't thinking about my deformed foot because it doesn't cause me any trouble in day to day life. When I got to MEPS on the day my enlistment began, I panicked and told everyone I could think of that I had forgotten about my foot when asked previously; I was pulling off my shoes and showing my deformed foot to anyone who cared to look.
Aside from causing laughter and exposing my fellow enlistees to my stinky foot, I got no reaction. I was told it was an honest mistake and that, if it didn't cause me trouble on a day to day basis, it wouldn't in the Navy (it didn't).
BTW, I myself developed a heart murmur in the military which turned up at my separation physical; they documented it and put me through a number of tests to make sure I was OK before they released me from active service.

I had flat feet (still do) when I was in the infantry in the early 70s. They were really scraping the bottom of the barrel then. There were guys who stuttered so badly, they couldn't make themselves understood; there were others that I swear were mentally retarded; others were alcoholics and criminals. My best friend had been dishonorably discharged from the Marines and enlisted in the Army (lying, of course). Just tell whoever asks that you're transgendered, and they'll let you in immediately.
