Dry weight is very important to the people on the list of dialysis. Doctors will ask their patients to weigh themselves before and after dialysis. What’s more, during the interval of dialysis, patients are strictly controlled on water or fluid diet intake. In order to understand the meaning of dry weight, at first we must know what it is and then the measure of controlling it will be introduced next.
The definition of dry weight
Simply speaking, dry weight is the weight after the excess water is removed in dialysis. With the ideal dry weight, patients will feel nothing discomfort, such as low blood pressure, swellings, palpitation, short of breath, the normal size of heart, thirsty, dry skin, etc.Can Ozone Therapy Reduces Dialysis and treatment Renal Failure
Therefore, the ideal dry weight can be set down in one time. As for the patients who take dialysis at first time, it will take two or three weeks to watch the change of their weight and clinical symptoms before and after dialysis. The relative dry weight can be found out after all factors are taken into consideration.
The meaning of dry weight
Dry weight determines how much water is removed during dialysis. The unreasonable dry weight setting will make dehydration and other fatal complications.Can Micro-Chinese Medicine Osmotherapy Benefit PKD Patients with Dialysis
If dry weight is set lower than the ideal one, more water will be removed to make patients reduce weight to the setting point. At this moment, patients are to show the symptoms of dewatering, such as fatigue, muscle twitches, low blood pressure, vomiting, weak pulse, shrinking heart in X scan, etc. On the contrary, if dry weight is set higher than the ideal one, there is still excess water depositing in body after dialysis. The water in lacuna is to elevate blood pressure and provoke hydrothorax, ascites as well as a sense of impending doom caused by Acute Left Heart Failure.
The method of maintaining dry weight
Normally patient on dialysis must be in their ideal dry weight once a week. The suitable diet for those patients must follow the principle of small amount with enough nutrients. If dialysis is taken every other day, the increased weight should be not more than 3% of dry weight. That is to say, before the next dialysis, a 50kg person would be better put on weight less than 1.5kg. If the person takes dialysis every three days, the increased weight should be less than 5% of his or her dry weight.Does Every PKD Patients Go for Dialysis
Controlling water intake
Water intake is another factor increase the weight of patients. As for patients with Polycystic Kidney Disease (PKD), without effective treatments, they may suffer from Kidney Failure in future. As kidney fail in filtrating and draining metabolic wastes out, every sip of water will be accumulated in body. The suitable water intake is usually not more than the volume of urine the day before, but it is still ok for patients take 500mL water a day more than their urine the day before. After they have heavy sweating, 100 to 200mL is added to their water intake. Doctors suggest that the water should be divided reasonably in a whole day. When they have their medicines, 450mL water is used for having medicines three time a day. In addition, a cup of milk or a bowl of porridge or soup contains 200mL of water, while an apple of 120g contains about 50mL of water. Doctors and the family members of patients should pay more attention to the water intake of patients on the list of dialysis.
