This document provides an overview of glomerulonephritis, including its causes, symptoms, and principles of dietary management. Glomerulonephritis is an inflammation of the glomeruli in the kidneys, which are structures that filter blood and remove excess fluids. It can be caused by genetics, infections, immune system problems, or other issues. Symptoms may include blood in the urine, fatigue, swelling, and changes in urination. Dietary management focuses on managing fluid intake, providing adequate calories and nutrients while restricting sodium and protein intake, depending on the severity of the condition. The goals are to reduce swelling and support kidney function during treatment.
