My mother has diabetes and dementia. On Friday morning, she awoke after having vomited in her bed, but doesn t speak, so it wasn t noticed until my father got up and saw it on her face that he realized what had happened. He noticed also that now her walking was very slow and she s kind of hunched over. The hospital did a bunch of tests, and found only that her blood sugar was extremely high, at 400, and an enlarged thyroid. Can an enlarged thyroid cause problems with walking and hunching over?
