Scanty/difficult urination
Also called:low urine outputurinary retention
From the TCM perspective: Impaired bladder qi transformation
Overview
Scanty or difficult urination means low output or a weak/strained stream. TCM links it to impaired bladder qi transformation—damp-heat or stasis obstructing (painful/burning), or kidney/spleen yang deficiency failing to move fluids (cold weak stream). A sharp fall in output is medically urgent.
