The Five Stages of Chronic Kidney Disease, Symptoms, Early Diagnosis, and the Importance of Prevention<\/strong><\/h3>\n

Kidney dysfunction manifests through the five stages of chronic kidney disease (CKD), also known as chronic renal failure. The loss of kidney function is caused by underlying pathological conditions. A key feature of CKD is that it presents no symptoms during the first two stages<\/strong>. Therefore, CKD is difficult to diagnose in its early stages, making prevention and early diagnosis essential<\/strong>.<\/p>\n

\n

Key Data for Diagnosing Chronic Kidney Disease<\/strong><\/h3>\n

To diagnose CKD early, it is necessary to monitor specific health values, starting with the Glomerular Filtration Rate (GFR)<\/strong>.<\/p>\n

This value, along with proteinuria<\/strong> (the presence of proteins in the urine), classifies the stage of kidney disease. Proteinuria can be assessed either over 24 hours or as the albumin-to-creatinine ratio (ACR)<\/strong>. The normal GFR range in adults is 100\u2013120 mL\/min<\/strong>.<\/p>\n

\n

The Five Stages of Chronic Kidney Disease<\/strong><\/h3>\n

Stage 1<\/strong><\/h4>\n

The first stage is asymptomatic and features a normal or slightly increased GFR<\/strong>. However, this alone is not sufficient for a CKD diagnosis. If proteinuria is also present, it may serve as an early warning sign.<\/p>\n

\n

Stage 2<\/strong><\/h4>\n

Stage 2 is also asymptomatic, but unlike stage 1, it involves a slight reduction in GFR<\/strong>. If significant proteinuria is detected, an immediate consultation with a nephrologist<\/strong> is recommended. This becomes especially important when GFR is significantly reduced and high albuminuria<\/strong> (excess albumin in the urine) is present.<\/p>\n

\n

Stage 3 \u2013 The Onset of Renal Insufficiency<\/strong><\/h4>\n

Stage 3 of CKD is split into two subcategories. From this stage onward, the condition is considered chronic renal insufficiency<\/strong>, and a nephrologist consultation becomes essential<\/strong>. Stage 3 is marked by a GFR below 60 mL\/min<\/strong>.<\/p>\n

    \n
  • \n

    Stage 3a<\/strong> may still show no symptoms, but action can be taken to slow disease progression.<\/p>\n<\/li>\n

  • \n

    Stage 3b<\/strong> is often accompanied by symptoms like malnutrition, bone pain, nerve numbness, and concentration difficulties<\/strong>. Secondary hyperparathyroidism<\/strong> and anemia due to CKD<\/strong> are also common at this stage.<\/p>\n<\/li>\n<\/ul>\n

    The nephrologist typically prescribes drug therapy and a specific dietary program<\/strong> to reduce disease progression and prevent metabolic imbalances.<\/p>\n

    \n

    Stage 4<\/strong><\/h4>\n

    Stage 4 involves a significant drop in GFR<\/strong> and is characterized by noticeable reductions in physical strength and endurance<\/strong>. The nephrologist recommends an even stricter diet with low-protein foods<\/strong>. Erythropoietin supplementation is also prescribed to treat anemia. Metabolic complications become more evident in this stage.<\/p>\n

    \n

    Stage 5<\/strong><\/h4>\n

    This is the final stage<\/strong> of kidney failure, defined by a GFR below 15 mL\/min<\/strong>. At this point, the patient enters a predialysis phase<\/strong> under the nephrologist\u2019s supervision. Several factors are assessed to determine whether dialysis should begin:<\/p>\n

      \n
    • \n

      Elevated blood urea nitrogen (BUN)<\/strong><\/p>\n<\/li>\n

    • \n

      Changes in urination frequency<\/strong><\/p>\n<\/li>\n

    • \n

      Presence of edema (swelling)<\/strong><\/p>\n<\/li>\n

    • \n

      Anemia<\/strong><\/p>\n<\/li>\n

    • \n

      High levels of parathyroid hormone (PTH)<\/strong> and phosphorus<\/strong><\/p>\n<\/li>\n<\/ul>\n

      Dialysis becomes necessary when these factors can no longer be managed through diet alone<\/strong>.<\/p>\n

      \n

      Prevention<\/strong><\/h3>\n

      As with other diseases, prevention is crucial<\/strong> for chronic kidney disease and kidney failure. In CKD, prevention is even more important, as early stages typically lack warning signs.<\/p>\n

      The first step<\/strong> in identifying potential kidney disease is to evaluate renal function through GFR testing<\/strong>, along with measurements of creatinine<\/strong> and albumin<\/strong> levels in the urine.<\/p>\n

      Blood tests<\/strong>\u2014especially for creatinine, albumin, urea, sodium, potassium, calcium, PTH, and complete blood count\u2014along with urinalysis<\/strong>, help monitor the disease’s progression toward advanced stages and are the primary tools for early detection.<\/p>\n

      At Nefrocenter\u2019s Centers of Excellence<\/strong>, all laboratory tests needed for the prevention, diagnosis, and treatment<\/strong> of chronic kidney disease are available.<\/p>\n","protected":false},"excerpt":{"rendered":"
