I'm not sure how much research has been done regarding secretin and ph, but we do know that secretin prompts the duodenum to release that gush of bicarbonate. Now it would stand to reason that for an individual with a low ph, this would spell relief. But I think not for an individual already in a state of alkalosis. It is an interesting point. After the disappointing experience with secretin, I began researching ph balance in the body.
Most autistic children do seem to be on the acid side.
I began testing urine and saliva ph. One of my twins hung consistently in the 8.0-8.5 range for almost a year. Recent stool testing revealed a gut ph of 7.2, again leaning toward the alkaline side.
