Overview

Definition

Glomerulonephritis stems from injury to the tiny tubules inside the kidneys. They filter wastes from blood and make urine. If they aren’t working well, wastes build up in the in the body.

There are 2 types:

  • Acute—starts up quickly
  • Chronic—grows slowly over time

  • Renal ultrasound
  • Kidney biopsy

You will be referred to a specialist for care.

Treatments

Treatment

The care depends on the cause. The focus is to maintain kidney function and lower the chances of further injury. Care may involve:

  • Changes to your diet to manage protein, salt, and electrolyte balances
  • Medicines will help manage other problems such as high blood pressure or fluid build up
  • Dialysis—a machine works for your kidneys by filtering your blood
  • A kidney transplant
