Pattern Overview

Bladder Damp-Heat is the most common pattern in acute urinary tract infections, characterized by acute bacterial cystitis, burning urination, frequent urination, urgency, yellow or turbid urine, and lower abdominal pain. The core pathogenesis is accumulation of Damp-Heat in the Bladder, causing bacterial colonization, mucosal inflammation, and urinary irritation.
