Can a non diabetic patient suffers hypoglycemia?

Define: Hi. Please define hypoglycemia. If you're not taking diabetes drugs, true pathological hypoglycemia is vanishingly rare. Did you become confused, lose consciousness, have a seizure? If not, there is a popular self-diagnosis of "hypoglycemia" that isn't real. There are rare familial syndromes where pancreatic tumors can occur that cause pathologic hypoglycemia. See an endocrinologist if indicated.

Reactive hypogly. : If you're referring to reactive hypoglycemia, then that to which you refer is fairly common. It's related to the overly brisk response of the pancreas to ingestion of simple sugar. Non-diabetics can certainly experience this.
