The Stages of Chronic Kidney Disease

By: Anapol Weiss

Chronic kidney disease (CKD) is a progressive condition that involves the gradual loss of kidney function. Many kidney specialists use a system involving stages to describe patients’ symptoms as the disease progresses, according to the National Kidney Center.

Stage 1

90% Kidney Function

Most people do not know they have stage 1 CKD, as they may not experience any symptoms. However, factors such as abnormally high levels of creatinine or urea in the blood, blood in the urine or evidence of kidney damage in an MRI, CT scan or ultrasound could show stage 1 CKD.

Stage 2

60% to 89% Kidney Function

Patients may still be symptom-free during stage 2, but some people start having problems with high blood pressure.

Stage 3

40% to 59% Kidney Function

Symptoms such as fluid retention, swelling of the extremities, changes in urination and kidney pain may appear during stage 3. As stage 3 progresses, patients often see a nephrologist to discuss their condition and a treatment plan to keep their kidneys working as long as possible.

Stage 4

15% to 29% Kidney Function

Stage 4 involves severely reduced kidney function. A patient with stage 4 CKD will likely need dialysis or a kidney transplant in the near future. During stage 4, a person may develop complications such as high blood pressure, anemia, bone disease, or cardiovascular diseases.

Stage 5

Less Than 15% Kidney Function

Stage 5 is also referred to end-stage renal disease (ESRD). When a patient’s CKD has reached stage 5, his or her kidneys cannot adequately function without dialysis or a kidney transplant.

An increased risk of chronic kidney disease has been associated with a widely-used class of drugs called proton pump inhibitors (PPIs), which are typically taken to treat ulcers and conditions such as gastroesophageal reflux disease (GERD). Popular brands of PPIs include Prevacid, Protonix, Nexium and Prilosec.

If you took a PPI drug over an extended period of time and were diagnosed with chronic kidney disease, you may have questions about who is legally responsible and if there is possible compensation for medical bills, loss of work and other financial and personal losses.
