Every military branch requires that you be of physically sound mind and body, as such you are required to complete a physical at a local MEPS. At MEPS, doctors will test everything from your vision and hearing to your joints, blood, and urine. The military wants to make sure that there is nothing that would put you at risk of injury or death because of some inability to carry out your duties as an officer. You start the day by completing a Medical Questionaire in which you will be asked to detail your medical history. This questionaire will be added to your packet.

They will ask for every detail. Give it to them. As I said before, with some exceptions everything is waiverable. Serious heart conditions or asthma are the kinds of things that are not but if you don't tell the doctors about something and it is discovered later on then you will be looking at a dishonorable discharge, fines and maybe even prison time for falsifying medical information.

Some medical issues may require that you have an independent consultation. For example, if you suffered a head trauma at some time a neurological consult might be required just to make sure everything is as it should be. This is one of those case-by-case requirements I mentioned earlier.
