Many patients will feel thirsty when they are undergoing dialysis. Is this
normal and can patients drink more water at this moment?
Experts say that the water that go out of body when doing dialysis is not
from the water we drink. It is from the blood. If patients consume too much
water during the ten hours after dialysis, the water will be reabsorbed into the
blood. In this way, patients will have a swollen heart and too much water will
increase the workload of the heart. More water building up in the heart will
lead to heart failure. If the content of potassium is high, the heart can stop
work suddenly. So, experts remind that patients should control their water
intake strictly when they are undergoing dialysis.
How much water can patients take when they are undergoing dialysis is
determined by their specific illness condition. The general principle is keeping
a balance. Patients who are undergoing dialysis should record their weight
everyday. The increased weight during dialysis should be kept in 1-1.5g. The
weight change in a short time is caused by the water amount in the body.
Generally, patients who are undergoing dialysis once a week, the water intake
should be the urine volume in 24 hours +100ml. For patients who do not have
urine, the water intake should be not more than 100ml.
For patients who undergoing dialysis twice a week, the water intake should be
the urine volume in 24 hours plus 300ml. The water intake should not be more
than 300ml for patients who do not have urine volume.
For patients who are undergoing dialysis three time a week, the water intake
should be 24-hour urine volume +500ml. For those who do not have urine, the
water should not be more than 500ml a day.
Besides water, patients’ diet should also paid special attention to.
1. Low oil and low cholesterol diet: patients who have are undergoing
dialysis often have hyperlipemia. So for fear of the aggravation of
arterosclerosis, patients should strictly control their fat and cholesterol
intake.
2. Soluble fiber: besides consuming much food containing soluble fiber,
patients can take medicines orally as a supplement, Such as Vitamin B2, folic
acid, pyridoxine, ascorbic and acid etc.
3. Potassium, Sodium, Calcium, Phosphorus: the intake of the above substances
should be regulated according to your blood test. The intake of sodium should be
controlled in 1500-2000mg. The intake of sodium should especially strict when
patients have no urine output. Generally, the potassium and urine output should
be less than 1300mg per day. The phosphorus should be kept in 4.5-5.0mg/dL.
Patients should the supplement of calcium for fear of the decline of its
volume.
