She says the same that you are saying about having
symptoms, especially hypoglycemia (now she knows that is what it was)
pre diabetes. She believes she had symptoms years prior to her diagnosis. No one tested her for it, nor did she know much about diabetes and then she was finally diagnosed.
I do not remember my son having a lot of illnesses prior and as far as lows, he was only 3, so he would not have been able to describe them.
