Did CGA ask you to submit anything in particular? Are all of these current issues or are they "history of" from years ago? If they are no longer current, then submit your medical records to show that. Either way, if you don't believe they are issues that will affect your ability to serve, then having a specialist in each area write a letter explaining addressing the main concerns would be helpful.
If you look at the DODMERB documentation, there is section explaining what DODMERB (and the SAs) are really concerned about for medical issues:
“4c. Ensure that individuals under consideration for appointment, enlistment, or induction into the Military Services are:
(1) Free of contagious diseases that probably will endanger the health of other personnel.
(2) Free of medical conditions or physical defects that may require excessive time lost from duty for necessary treatment or hospitalization or probably will result in separation from the Service for medical unfitness.
(3) Medically capable of satisfactorily completing required training.
(4) Medically adaptable to the military environment without the necessity of geographical area limitations.
(5) Medically capable of performing duties without aggravation of existing physical defects or medical conditions.”

17. Generalized waiver criteria – The main focus of all waiver decisions is centered on the ability to safely and successfully train, be commissioned, and be world-wide deployable upon graduation/commission. In applying this objective, a few of the questions that are considered are:
a) Is the condition progressive?
b) Is the condition subject to aggravation by military service?
c) Will the condition preclude satisfactory completion of prescribed training and subsequent military duty?
d) Will the condition constitute an undue hazard to you or to others you will be charged in leading, particularly under combat conditions?
