Insulin (diabetic) induced hypoglycemia
A much more serious type of hypoglycemia occurs when a diabetic takes more insulin than is needed to metabolize the available glucose. The onset of symptoms of an insulin reaction— hunger, tingling sensations, sweating, faintness, impaired vision, mood changes, palpitations, and a cold, clammy sensation—can be reversed by immediately eating a tablespoonful of sugar or honey, sucking on a hard candy, or drinking a glass of orange juice or a sugary drink. Do not ignore insulin reactions.
