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

Why do you have to go to a cardiologist if they didn't find it at MEPS? If you grew out of it when you were younger, than its no problem. If you still have it, it limits where the military can place you, if you are accepted. If you out and out lied and it is discovered, kiss your military career good-by. If you are let 'in' and they find out you lied, you'll be put out.
Lots of people have murmurs and it never effects them, others have problems throughout thier lives. I will not attempt to diagnose your murmur, but the doctors will.

They will now! It's called a fraudulent enlistment!

What this all really comes down to is not whether this young person is fit for duty, that is for the Army medical staff to decide, but their character. Did they misconstrue what doctors told them when they were a child to get into a branch of service? Depends on their motives. Did they do it for the sole purpose of donning the uniform to serve in our great military? Or were some truths omitted in order to serve and then file a disability claim on down the line for the condition? Only this young person knows what their intentions were. What is plain to see is that their good character has come out and shows that they have a conscience for right and wrong. If they didn't care or were really trying to defraud the system the question would never have be put on this site. My advice, along with so many others would be to disclose what you do know. Start your careers off on the correct foot and don't go into something that blemishes your sacrifice and service. Recruiters we love em' but they can be manipulative, and sometimes have folks "forget" certain things so they can them into service. Honesty is the best policy. Have people gotten screwed over from telling the truth? Sure we all have, but I would rather be screwed by the truth than by a lie. So if Dr. Sawbones says the kid is G2G then let them take up arms. If they are not, or know for a fact they are not, then I would tell them that their are other avenues to take to serve our great nation. I've seen folks that had alot of heart but couldn't meet the standard. There are standards for a reason. To keep people alive and complete the mission.

*Loyalty, Duty, Respect, Honor, Selfless Service, Integrity, and Courage. We know them. We taught them. Hopefully some of us practiced them. Speak your mind in a respectable fashion, and honor your fellow service member or veteran while doing so. We all wear or have worn the uniform. One team, One fight.

If you had not wrote this post, I would say probably. But since you ratted yourself out, I say DEFINITELY.

Dude, really? This isn't the kind of thing to post on the internet.

I completed my physical for the US Air Force in October 1968 at Fort Hayes, Ohio. I reported for basic training shortly after at Lackland Air Force Base, Texas. We went through uniform issue, set up housekeeping, and had a couple of days to get acclimated. Then the day came when the entire squadron marched out by flights for PT. The PT uniform was combat boots, utility uniform trousers, and t-shirt. Our tunics and head cover were placed neatly on the ground. We did not run in formation. The first day my flight of newbies was assigned to run one complete circuit on the 1/4 mile track. A couple of days later that was increased to two circuits as our conditioning improved. There were always stragglers and those who could not complete the course.
There were always ambulances and medics on site to attend to those who fell out or passed out. Our third Saturday we were up to running four circuits, one mile. It was a particularly warm and humid day. The squadron began the run. It wasn't too long before the first troop fell on the track and was evacuated via ambulance to the hospital 1/2 mile away. Before the first ambulance had returned, the second ambulance left with another troop. When the first ambulance returned it was loaded with a third troop. They made eight runs that morning for dehydration, exhaustion, and heart attacks. Eight went to the hospital, four came back, and two died of heart attacks. We lost on average one man a day, six days a week, for the first three weeks of training due to physical training and medical conditions.
Asthma, allergies, heart murmurs, and other conditions are no joke. You could say that they are "as serious as a heart attack". I applaud your willingness to serve, but it isn't worth becoming a statistic. I went on to complete Canadian Forces basic twelve years later, and U S Army basic sixteen years later at 34 years of age. I saw the pattern of highly motivated people betting their lives and losing every time. Don't do it.

I understand this was published over a year ago but I am generally always late to the party... LOL
1. Unless authorized to do so, which you would have to allow them to (i.e. you would have to grant them permission to by signing something) look into your records when you were a minor.
2. Unless they have reason to ask for permission they generally dont look into records prior to your enlistment that are not tied to education, and criminal history.
3. To emphasize what LTC Jason Mackay said THIS IS A PUBLIC WEB SITE AND YOU JUST MADE A PUBLIC STATEMENT THAT YOU LIED TO THE GOVERNMENT TO GAIN ENTRY INTO THE MILITARY.
4. Probably nothing will come of this regardless, but you should think more in the future before you say things on an open network.

Among many other things, I was a legal officer and an administrative job ('rating') in the Navy. My Captain, and then later myself, always referred those soldiers/sailors/airmen/marines/coastguardsmen and women, who had a repetitive pattern of missing PT (i.e., anything that brings you this kind of 'what the ...' attention is not good; missing PT or a whole workday for days and weeks on end is just one of the many examples), to review their medical and dental records. And consistently opting for 'sick call' for an illness that is suspiciously constant, or some other person mentions seeing this 'sick' person out and about, could and would also cause me to, or have my commander have me, review their medical and dental records. Or, I would request a physician at the base's MTF to please look into any known or similar ailments the soldier mentioned at their MEPS delayed entry physical and then their MEPS shipping or ship day, boot camp day, physicals. Any inconsistencies prompted two things: first: with concurrence from the MTF's treating physician, we'd verify the member had this before entry and failed to disclose it; or, second: a pattern of misconduct and providing false statements (i.e., both charges [misconduct; false statements] can come from the lack of disclosing all known medical ailments at your exams) can cause a member to face punitive or non-punitive measures (this means either a court-martial or an Article 15 hearing). We would also pursue the separation of this member (soldier) via a variety of methods (i.e., mainly administrative separation and an OTH characterization of service on the DD-214). I strongly urge you to disclose your previously undisclosed but known issue. My last tenure or duty station was as the Chief Liaison and Enlisted Classifier at MEPS in Spokane. I assure you, it can come up to haunt you in your future if it doesn't spring up at your shipping date (or the day you swear in a second time and fly out to boot camp). I am a Navy Chief, so we call it ship date or 'shipping date.' - Thank you. "You do what's right because it's the right thing to do." P.S. So far, my peers' comments, and yours, in all ranks, and on the Enlisted and Officer side favor disclosing the full truth. I will say, based on real and first-hand experience working with recruiting and inside MEPS, it will not go over well when you are honest because the recruiter will need to get the paperwork. But, if you wait until your 'shipping day' and then disclose it, you will most likely be in serious and turbulent water with your recruiter's CSM (or CMC, CMDCM, or just 'TOP'), Division/Squad/Platoon Officer, and possibly the Commander him-/her-self. Be honest and committed to such; it's how you shoot straight and how to serve with HONOR.

50 years ago I know for certain that whatever the final decision is, that's it unless you continue with the malady once your in. Then you will get an undesirable discharge-no big deal. I have never had anyone ask about my military service, anywhere, anytime except at the VA for bullet damage.

Make it past 180 days and document each time you go to sick call.
