Mechanism of Postprandial Drowsiness and the Clinical Application under the Model of WeiQi Circulating from Yin to Yang
Postprandial drowsiness is a clinical condition characterized by pronounced drowsiness after meals, while
The Inner Canon of Yellow Emperor
(《黄帝内经》) associates this condition with
wei
qi
(defensive
qi
). By analyzing the original texts of
The Inner Canon of Yellow Emperor
and perspectives from many medical professionals, it is found that the transition between wakefulness and sleep depends on the mutual induction of
yin
and
yang
, and that the two pathways of
wei
qi
circulation intersect at the spleen and stomach. Based on this, the core pathogenesis of postprandial drowsiness is proposed to be either upper
jiao
obstruction or spleen-stomach dysfunction, leading to the stagnation of
wei
qi
internally, then the mutual induction of
yin
and
yang
causes inward invasion of
wei
qi
in the body, resulting in drowsiness; at this stage, the stagnated and inward invasive
wei
qi
converges at the spleen and stomach, then merges into
the circulation of
zang
-
fu
organs, rerouting through the Foot Taiyang Meridian, forming a circulation pattern described as "circulating from
yin
to
yang
". Treatment should focus on the root and branch simultaneously, with the primary goal of regulating the circulation of
wei
qi
; facilitating its transition from
yin
to
yang
to restore the sleep-wake cycle. By proposing the model of
wei
qi
circulating from
yin
to
yang
, this study offers novel insights on the understanding of postprandial drowsiness.
