Glomerular Disease: Symptoms, Diagnosis, and Treatment

What is Glomerular Disease?

One of the most important functions of the kidney is to filter waste out of your blood using a million tiny filters called glomeruli. A glomerulus works a little bit like a kitchen colander, allowing waste and water to pass through to create urine.

Usually, blood will not pass through the “holes" in the colander, and instead return to your body. But if you have a kidney disease that damages your glomeruli, which we call glomerular disease, glomerular disease, blood will pass through the holes and enter your urine.

Glomerular diseases can vary from mild to very serious and include some diseases that rapidly lead to loss of kidney function.

Glomerular disease is a common cause of chronic kidney disease. Among patients on dialysis, about 15 percent have a diagnosis of glomerulonephritis, and another 30 to 50 percent have other glomerular diseases, such as diabetic nephropathy or high blood pressure.

Causes and Types of Glomerular Diseases

Glomerular disease can be caused by:

  • Autoimmune diseases
  • Infections
  • Medications
  • Genetic disorders
  • Diabetes

Sometimes glomerular disease has no identifiable cause. When this happens, it is called idiopathic.

Risks and Complications of Glomerular Disease

The most serious risk of glomerular disease is chronic kidney disease. Some glomerular diseases cause a slowly progressive chronic kidney disease, and it might take 15 to 20 years to lose all kidney function. Other glomerular diseases cause a loss of kidney function in weeks to months. The sooner your kidney disease is diagnosed and treated, the higher your chances of slowing the progression of your illness and avoiding dialysis or kidney transplant.

Glomerular Disease Symptoms and Diagnosis

Glomerular disease often has few symptoms, but you may notice:

  • Pink or brown pee from the presence of red blood cells
  • Foamy pee from excess protein
  • High blood pressure
  • Swelling or retaining fluids

Diagnosing Glomerular Disease

To diagnose glomerular disease, your doctor will likely run:

  • Urine tests.
  • A blood test called Glomerular Filtration Rate (GFR) to measure how well your kidneys filter. A GFR result of 90 or above indicates normal kidney function.
  • Imaging tests, such as CT scans or x-rays.
  • A kidney biopsy.

Glomerular Disease Treatment

Early and precise diagnosis of glomerular disease is vital. Timely treatment is key to avoid kidney failure.

Treatment may include:

  • Diet changes and exercise
  • Medicine to control blood pressure control
  • Medicine to suppress the immune system.

Prevention of Glomerular Disease

It isn't always possible to prevent glomerular disease.

But you can reduce your risk by following doctors' orders:

  • Control your blood pressure if it's high.
  • Control your blood sugar if you have diabetes.
  • Seek prompt treatment for strep throat or impetigo infections.
  • Practice safe sex and avoid IV drug use to prevent infections like hepatitis and HIV.
