Healthy kidneys can perform to balance fluid in the body.In kidney disease, the diseased kidneys fail to work adequately.If excess fluid builds up in body, it can cause fluid overload which can elevate blood pressure and may contribute to heart disease.Therefore, it is important to adjust the fluid intake for people with Kidney Disease.
Dialysis can take over a partial function of the kidneys to remove some fluid from body.Thus,the patients can have a less restrictive fluid intake. What is the recommended fluid intake in kidney disease with and without dialysis?
Fluid intake in chronic and acute nephritis
If the patients with Nephritis have edema and high blood pressure,they should determine their fluid intake based on their urine output and edema degree.If they just have mild edema,they only need to reduce fluid intake slightly. If oliguria and serious edema occur,they should keep a salt-free and reduce fluid intake.The amount of fluid equals to urine output of previous day plus about 500ml.For example,if the urine output is 1500ml, the total amount of fluid intake should be 1500+500=2000ml. How much fluid should you intake? We can help you analyze your condition and give you a reference. You can email to email@example.com to send us your medical report.
Fluid intake in Nephrotic Syndrome
A typical manifestation of nephrotic syndrome is edema due to retention of fluid and sodium.The fluid intake in nephrotic syndrome can refer to the principle of fluid intake in nephritis.
Fluid intake in kidney failure without dialysis
When GFR reduces below 2~5ml/min, the patients susceptible to edema. Therefore,it is very important to restrict the intake of fluid.If excess fluid builds up in body, it can cause shortness of breath, high blood pressure, pulmonary edema and congestive heart failure.However, in some cases, the urinary concentrating defect occurs,the urine output increases drastically.Deficient fluid intake can lead to dehydration.The recommended fluid intake equals to the urine output of the previous day plus about 500ml.
Fluid intake in the kidney failure with dialysis
Most of patients on maintenance Dialysis suffer oliguria or anuria,they should particularly cautious in adjusting their fluid intake. In general, the recommended fluid intake should be not higher than 1000ml/d, including fluid in foods.
Either excess or less fluid intake is harmful to the patients with kidney disease. So you should refer to a dietitian to decide your fluid intake.
