I hope I didn't make it sound like all hypoglycemia is Toxic Hunger. Just saying one's hypoglycemia *may not* be, but instead Toxic Hunger.
Dr. Fuhrman mentions reactive hypoglycemia can be a symptom of Toxic Hunger. A couple people on here seemed like they may have had this because they said they either passed out or felt so bad they had to go to the emergency room only for the test results at the hospital coming up that their glucose levels were fine.
I advice anyone who has low blood Sugar symptoms to immediately start monitoring their glucose levels. If your levels are normal, then that's a sure bet you have Toxic Hunger instead.
There are a couple of rare types of hypoglycemia caused by tumors that cause constant elevation of insulin.
