The most common form of kidney disease is chronic kidney disease. Chronic kidney disease is a long-term condition that does not improve over time. It’s commonly caused by high blood pressure. High blood pressure is dangerous for the kidneys because it can increase the pressure on the glomeruli.weight loss and poor appetite. swollen ankles, feet or hands – as a result of water retention (oedema) shortness of breath.tiredness.blood in your pee (urine)an increased need to pee –particularly at night.difficulty sleeping (insomnia) itchy skin.Stage 3 CKD means you have an eGFR between 30 and 59 and mild to moderate damage to your kidneys. Your kidneys do not work as well as they should to filter waste and extra fluid out of your blood.In Stage 5 CKD, you have an eGFR of less than 15. You may also have protein in your urine (i.e., your pee). Stage 5 CKD means your kidneys are getting very close to failure or have already failed. Kidney failure is also called end-stage renal disease (ESRD) and end-stage kidney disease (ESKD)Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood’s chemical makeup may get out of balance.Chronic kidney disease can progress to end-stage kidney failure, which is fatal without artificial filtering (dialysis) or a kidney transplant.Blood Tests. Because your kidneys remove waste, toxins, and extra fluid from the blood, a doctor will also use a blood test to check your kidney function. The blood tests will show how well your kidneys are doing their job and how quickly the waste is being removed.The blood test checks your GFR—glomerular filtration rate. GFR is an estimate of your kidney’s filtering ability. A GFR below 60 is a sign of chronic kidney disease. A GFR below 15 is described as kidney failure.Simple urine test: Usually, albumin is not present in urine. This test kit is convenient and can accurately diagnose albuminuria (presence of albumin in the urine), which is a sign of kidney damage. A person may keep a record of the extent of albuminuria and plan a visit to the doctor accordingly.
