I was negative on all testing: blood, skin, and stool. I have hla1 genes which my doctor didn’t even know was the neurologically presenting gene. And yet when I gave up wheat my reflux, yawning, shortness of breath, belly pain, bloody stools, loss of voice, arthritis, asthma, fatigue, and hypoglycemai magically went away. A miracle cure. My asthma doctor said maybe the Pepicid started working (it had been two years)!
Now I’m paleo grain and sugar free with intermittent fasting and I’ve never felt better.
I’d rather eat glass than wheat. (And my testing was all negative!)
