I am curious why symptoms of postprandial anxiety, tachycardia, hypertension, etc are always investigated through the lens of hypoglycemia as in an adrenergic response. Wouldn't cholecystokinin, specifically CCK2 or CCB, be a better differential for these symptoms? Patients generally get labeled with Postprandial Syndrome and most claim that it doesn't exist, or is strictly an anxiety disorder. It seems as though the CNS role of CCK is overlooked in these investigations.
