Why do patients with Polycystic Kidney Disease (PKD) feel thirsty after
hemodialysis treatment? With the enlargement of the kidney cysts, they will
compress the surrounding normal renal tissues and renal functional cells. And
due to the decline of the kidney filtration functions, the creatinine level of
the patients begins to increase. Therefore, patients have to take hemodialysis
treatment when the creatinine increases to certain level. But why do patients
with Polycystic Kidney Disease (PKD) feel thirsty after hemodialysis
treatment?
This problem mainly is mainly resulted from deficient and irregular
hemodialysis treatment.
1, disorder of water and electrolyte: when patients are in the stage of renal
failure or the end stage of renal failure, the retented water amount in the
patient’s body is times of that of healthy people. Large amount of water
permeates into the tissue space after passing through the blood capillary wall
under the function of blood osmotic pressure and fluid static pressure, which
will increase the extracellular osmotic pressure and lead to the dehydration
state of extracellular fluid.
2, the relative insufficience of the blood volume: as for the patients in the
stage of renal failure and in the end stage of renal failure, there are large
amount of water existing in the tissue space, which result in the relatively
insufficience of the effective circulation of blood volume. And then organism
will stimulate the thirsty central of hypothalamus through the reflexive of the
osmothic pressure receptor, then the patients will feel thirst.
3, affection of toxins: as the kidneys have been seriously damaged, they
can’t eliminate toxins out of the body normally. Then the toxins, such as serum
creatinine, BUN and uric acid, will retent in the body. In order to eliminate or
dilute the various toxins and the high concentrations of sodium, patients have
to take in more water, so the patients will have the feelings of thirsty.
4, psychological factors: these psychological factors exist among most
patients who are taking hemodialysis treatment. Though the thirsty feeling is
not so much strong, the desire for water still exists.
To resolve the problem: why do patients with Polycystic Kidney Disease (PKD)
feel thirsty after hemodialysis treatment, patients need sufficient and regular
hemodialysis treatment. If you have other doubts about this problem, please send
