Influence of breakfast on hemodynamics after lunch - a sonographic evaluation of mesenteric and cervical blood flows.

Hemodynamics is subject to change after eating meals, which may be related to various postprandial physical statuses such as hypotension or daytime sleepiness. Previous studies have shown that blood flow in the superior mesenteric artery (SMA) increases after meals, but conflicting results have been reported regarding blood flow in the common carotid artery (CCA). In those studies, the fasting interval before the meal was not taken into account.
