Commentary states: The bladder receives fluids. If the Qi mechanism fails to transmit and circulate normally, it results in fullness and distension of the lower abdomen. This may be caused by exertion after a full meal or sexual intercourse, causing the bladder to twist and close off (Bladder Reversal/Turn), leading to the inability to urinate, thereby resulting in "Bao Zhuan" (Bladder Reversal). The manifestations include obstruction of the urinary pathway, acute pain and tension in the lower abdomen, irritability, stifling sensation, sweating, and urgent, rushing Qi. In severe cases, it may lead to death; therefore, prompt treatment is required.
