Question: HI. Starting (3) years ago I started experiencing dizziness, unsteadiness, and light fatigue after eating high complex carb meal or simple sugars. (1) year ago, the symptoms progressed. 5 minutes to 40 minutes after a meal, I feel the above symptoms with confusion and extreme fatigue. Sometimes with palpitations and SOB. Cold intolerance in the hands. This may happen with even just one cracker within 5 minutes. I have eliminated most complex carbs and all simple sugars with some improvement. Another major symptom is exercise intolerance. I am unable to left or even ride a bike for 5 minutes without feeling extremely fatigued and very SOB. Other symptoms: dizziness when going from sitting to standing (more prevalent after eating) and chest congestion for about 30 minutes after eating. Blood pressure taken at lowest 92/68 after eating. History of milk protein allergy and chronic IC. NO milk in diet. Restricted salt in diet for last 6 years and no IC symptoms. Depo Provera injections for 12yrs. Last shot April 2014. Tests:

7/14:
GTT: sugars at 222 at 2 hours mark, insulin at 32. (retook two months later- sugars normal but no insulin level done). Endo believed high sugars due to restrictive carb diet. Introduced some carbs into diet before re-doing test. Took metformin for one week. Was able to tolerate more carb/sugar foods without dizziness but still extremely fatigued with 30 minutes. Recently tried Metformin again, and felt weaker, more fatigued.
ECHO negative
EKG: negative
PFT: possible restrictive lung dz, suggests parenchymal lung dz but ruled out by pulm doc after chest xray and examine

Any idea of a diagnosis?
