What Is Stage 3 Kidney Disease Treatment And Stages

What Is Stage 3 Kidney Disease? It’s a valid question, and at WHAT.EDU.VN, we provide the answers you seek. Understanding stage 3 CKD, chronic kidney disease stages, and kidney failure symptoms is crucial for effective management and care. Let us help you find the information you need about kidney function and renal disease progression and provide resources to get support.

1. Understanding Stage 3 Kidney Disease: An Overview

Stage 3 kidney disease, also known as stage 3 chronic kidney disease (CKD), signifies a moderate reduction in kidney function. Your kidneys are vital organs responsible for filtering waste and excess fluids from your blood, which are then excreted through urine. When kidneys are damaged, they cannot perform these functions efficiently, leading to a buildup of waste products in the body. This condition is categorized into five stages, with stage 1 indicating minimal damage and stage 5 representing kidney failure. Stage 3 is further divided into stage 3a and stage 3b, depending on the estimated glomerular filtration rate (eGFR).

1.1. What is eGFR and its Significance in Stage 3 CKD?

eGFR, or estimated Glomerular Filtration Rate, is a measure of how well your kidneys are filtering blood. It’s calculated using a blood test for creatinine, along with factors like age, sex, and race. In stage 3 CKD:

Stage 3a: eGFR is between 45 and 59 mL/min/1.73 m².
Stage 3b: eGFR is between 30 and 44 mL/min/1.73 m².

A lower eGFR indicates poorer kidney function. Monitoring eGFR is crucial to track the progression of kidney disease and adjust treatment plans accordingly. Regular check-ups and tests are essential for managing kidney health.

1.2. How Common is Stage 3 Kidney Disease?

Stage 3 CKD is relatively common, affecting a significant portion of the adult population, particularly older adults and those with underlying health conditions such as diabetes and high blood pressure. According to the Centers for Disease Control and Prevention (CDC), approximately 15% of U.S. adults have CKD, and many are in stage 3. The prevalence increases with age, making it a significant public health concern. Early detection and management are critical to slowing the progression of the disease and preventing complications.

2. Causes and Risk Factors of Stage 3 Kidney Disease

Several factors can contribute to the development of stage 3 kidney disease. Understanding these causes and risk factors can help in prevention and early detection.

2.1. Common Causes of CKD

The most common causes of CKD include:

Diabetes: High blood sugar levels can damage the blood vessels in the kidneys.
High Blood Pressure: Uncontrolled hypertension can strain and damage the kidneys over time.
Glomerulonephritis: A group of diseases that cause inflammation and damage to the kidney’s filtering units (glomeruli).
Polycystic Kidney Disease (PKD): A genetic disorder characterized by the growth of numerous cysts in the kidneys.
Urinary Tract Obstructions: Prolonged blockages in the urinary tract can cause kidney damage.
Vesicoureteral Reflux: A condition where urine flows backward into the kidneys, leading to recurrent infections and potential damage.
