This includes several conditions: Metabolic syndrome, Impaired Fasting Glucose, Insulin resistance, and Glucose intolerance.  The conditions must be stable.  The airman does not have any symptoms of diabetes.  The airman may not have had any hypoglycemic events. Fasting sugar no less than 70. Current hemoglobin A1C level should be less than 6.5.  Should an oral glucose tolerance test have been performed, the sugar at 1 hour cannot be greater than 1.  Metformin is the “only” oral agent permitted. 

Renal Cancer:

Lastly is kidney cancer.  The condition must be stable as in all the others.  The tumor cannot have extended beyond the capsule, no evidence of metastatic disease be present, and no paraneoplastic syndromes evident. Any treatments must be completed and airman back to full activities.

I am going to go over the final three medical conditions included in the CACI group. 

Migraine and Chronic Headaches:

The condition must be stable.  The diagnoses must be classical or common migraine, chronic tension (or muscle contracture headaches), or cluster headaches.  There can be no more than one headache episode per month.  In the year just prior to the certification there cannot have been any in-patient hospital admissions and no greater than two outpatient or urgent care visits for any exacerbations. The only daily prophylactic medications are calcium channel agents or beta-blockers. Now if the headaches are relieved by daily doses of NSAIDS, that would not be a problem either.
