Background: It is commonly known that headaches are induced by intake of specific food, drink, and/or additive. In addition, some patients experience postprandial headache independent of ingestion of specific items. Currently, information on the pathophysiology underlying this particular type of headache is scarce. Case reports: We report two cases in which headaches were observed after each meal. Postprandial hypotension was demonstrated in both cases. Tonometry-based continuous blood pressure measurement during head-up tilt revealed sympathetic dysfunction. In one patient, meta-iodobenzylguanidine (MIBG) myocardial scintigraphy detected cardiac sympathetic denervation, and diagnosis of pure autonomic failure was made. In both cases, treatment of postprandial hypotension was effective in relieving postprandial headache. Discussion: The possibility of postprandial hypotension should be explored in patients with headache that occurs after meal. To this end, tonometry-based blood pressure measurement and MIBG myocardial scintigraphy may be useful diagnostic investigations. Treating postprandial hypotension may be effective in alleviating the symptoms.
