A renal diet is a diet aimed at keeping levels of fluids, electrolytes, and minerals balanced in the body in individuals with chronic kidney disease or who are on dialysis. Dietary changes may include the restriction of fluid intake, protein, and electrolytes including sodium, phosphorus, and potassium. [1]
Partial fluid restriction can be used as therapy, but has the disadvantages of being difficult to maintain, and it is often ineffective. [6] Drugs causing increased diuresis is generally an alternative, and have less risk of causing decreased glomerular filtration rate through the kidneys and resultant decreased kidney function.
Demeclocycline can be used in chronic situations when fluid restrictions are difficult to maintain; demeclocycline is the most potent inhibitor of Vasopressin (ADH/AVP) action. However, demeclocycline has a 2–3 day delay in onset with extensive side effect profile, including skin photosensitivity, and nephrotoxicity.
Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis), hemofiltration, and hemodiafiltration, which are various ways of filtration of blood with or without machines. Renal replacement therapy also includes kidney transplantation , which is the ultimate form of replacement in that the old kidney is replaced by a donor ...
Fluid restriction to minimize the risk of edema (if not already present) or to reduce any active edema that may be present. [39] A special diet during the hospital stay that restricts sodium, potassium, and fluids in conjunction with the previously mentioned fluid restriction in an attempt to control symptoms of fluid overload. [40]
Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Kidney dialysis (from Greek διάλυσις, dialysis, 'dissolution'; from διά, dia, 'through', and λύσις, lysis, 'loosening or splitting') is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer ...

Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
