As a child, I was diagnosed with hypoglycemia. I had the typical symptoms; I was tired, shaky, irritable, and would have brain fog. My parents were told to keep me away from sweets and for years, I didn’t have candy. I remember even having pancakes with syrup would cause severe nausea and I’d have to lay down. I never really understood that if I had low blood sugar (hypoglycemia), why would putting sugar in the system bother me? It would seem that would be the way to fix it.
