Signs of Stage 3 Chronic Kidney Disease & How Can Diet Help With Stage 3 Chronic Kidney Disease?

What is Stage 3 Chronic Kidney Disease?

A person diagnosed with stage 3 chronic kidney disease (CKD) suffers from moderate damage to the kidneys. In addition, the stage comprises of two parts – reduction in GFR or Glomerular Filtration Rate to 45-49 mL/min in Stage 3A, and decrease in Glomerular Filtration Rate to 30-44 mL/min in Stage 3B.

The piling of the waste not only exerts pressure on the body but also declines the functionality of the kidney further. The entire scenario is life-threatening, as the rate of occurrence of kidney failure increases drastically. In stage 3 of kidney disease, the person is likely to develop anemia, high B.P (blood pressure), and bone diseases.
