Do they describe autonomic symptoms or panic attacks with sweating, tremor, pallor or palpitations?
Autonomic features of glycopaenia may be obvious. The attack may start with a feeling of hunger but quickly be described as more like a panic attack with anxiety, sweating, dizziness, tremulousness, pallor and palpitations. These symptoms, if not clearly related to fasting, may raise the possibility of thyrotoxicosis or phaeochromocytoma.
