Glucose is normally the primary source for brain energy. The brain can also use ketones, but this transition is gradual. Symptoms of hypoglycemia reflect 2 major clinical pathways. The first pathway is caused by activation of the autonomic nervous system, which causes symptoms such as sweating, trembling, flushing, anxiety, heart pounding, and hunger. The second group of symptoms is due to neuroglycopenia and includes an inability to concentrate, confusion, tiredness, feeling tearful, difficulty speaking, behavioral changes, incoordination, weakness, and drowsiness. Nonspecific symptoms include mouth tingling, dry mouth, blurred vision, headache, and nausea. These symptoms, of course, vary according to the age of the patient.
