I didn't understand some of what was being said, but his endocrinologist suggested that the GMO breads can be helping to aggravate some of the symptoms of his hypothyroidism, some of which includes poor sleeping. Since cutting out a lot of the glutton related stuff, his speech has improved and he's been sleeping better. It became an issue because his medication has been finicky. His blood test would go back and forth between too much medication and too little and he would sometimes display some of the symptoms of hypothyroidism when his T4 levels were where they were supposed to be. After going back and forth for a long time (only having had a few periods where his levels were properly balanced with no behavioral or other issues) the doctor suggested they look at dietary intolerance's and she now suggests he stay away from GMO breads. It could be an entire gluten thing and because my mom doesn't use a lot of gluten in his diet aside from breads, the doctor was just more specific about what to watch?
