I do not know much about gluten issues . What a i have been is a athlete my whole life i was a wrestler in high school and finished 5 in the nation. I was in the U S M C for 13 years until a combat injury allmost took my life and left leg from the knee down. I guess what i am trying to say is if your body is not responding from training or physical activity or is provoking a symptom maybee a visit to a doctor is good idea for a good thourough physical and some blood work. 10 years while in a three month training cycle for a power liftng meet i begain to experiance light headedness , dizzy spells , tunnel vision and it happened while not at the gym . Got into the doc asap he did a good thourough exam and blood work and all it turned out to be is low iron. 5. Years ago i started to feel myself thirsty, no energy in the middle of the day, i would get the shakes while lifting so back to the doc and shoot i had diabetes. You cant play it to safe with your health thats my two cents for what its worth
