As distinct from the Western medical concept of urinary bladder, this concept from traditional Chinese medicine is more a way of describing a set of interrelated functions than an anatomical organ.
As opposed to western medicine, where the bladders function is the storage and excretion of urine, the bladder in traditional Chinese medicine has extended functions, including how fluids are transformed during urine production.
If the kidney is yang deficient, the bladder may not have the sufficient qi and heat to transform fluids properly into urine.
This could result in overly clear urine that must be excreted more frequently.
