How do I start an MEB process in the National Guard?

You do not actually start a MEB. A doctor has to recommend you as unfit for duty. Then it can go to a board. If you think you may have a condition that qualifies you for a medical separation, you should ask for medical appointments to consult with a physician who will be able to make a more qualified prognosis.

A lot of great information as already been given, but since you came off profile that means, to me, you haven't been seeking treatment, or haven't been turning in documentation of those visits, you need to make regular appointments with whoever your primary care provider doctor is and have them give limitations, hell I have seen them written on a prescription pad, when you leave your doctor's appointment request copies of care given, diagnosis, progress, etc and give those to who ever your state surgeon rep is. In Texas we had a representative designated to each battalion. I also turned a copy into my unit readiness NCO as he was HIPAA trained. If you are not still seeking care I would recommend starting again because you will have to show that you are doing your part. If you get a temporary profile and in 3 months have nothing to support it then you will possibly come off profile again. At your next drill sit down with your Platoon Sgt, explain your situation, you DO NOT have to reveal the nature of the conditions.Tell him you would like to be scheduled for an appointment with a military doctor and go from there. Each state may have a different process for getting a profile but the easiest way is the annual PHA that was mentioned earlier.. I think we called them FMR, where you do shots, dental, etc..a mini SRB. Hope that helps.

Soldiers do not initiate a MEB, doctors do.
