My 21 year old son has never an appetite to speak of....he forgets to eat, even when he was a newborn. His BMI is 18-19 and he has low blood sugar. He also has epilepsy which seems to trigger seizures when he has not eaten. can low BS trigger seizures? Could his appetite and metabolic condition play a role in his seizures? Could he have an underlying metabolic disorder? Are the doctors who specialize in this field? Thanks much Barb
