Glomerulonephritis (various types)
What is Glomerulonephritis (various types)?
Glomerulonephritis is inflammation of the glomeruli, the tiny filters in your kidneys. These filters clean waste and extra fluid from your blood. When they become inflamed, they can leak protein and blood into your urine. Your kidneys may stop working as well as they should.
There are many types of glomerulonephritis. Some develop quickly over days or weeks, called acute glomerulonephritis. Others progress slowly over months or years, called chronic glomerulonephritis. The condition can happen on its own or as part of another disease like lupus or diabetes.
Early detection matters because untreated glomerulonephritis can lead to kidney failure. Many people catch it through routine urine tests before symptoms appear. Understanding your kidney health helps you take steps to protect these essential organs.
Symptoms
- Blood in urine, making it pink or cola-colored
- Foamy urine from excess protein
- Swelling in face, hands, feet, or abdomen
- High blood pressure
- Fatigue and low energy
- Less frequent urination than usual
- Shortness of breath from fluid buildup
Some people have no symptoms in the early stages. The condition may only show up through urine testing. This is why regular kidney health screening is important, especially if you have risk factors.

Causes and risk factors
Glomerulonephritis has many possible causes. Infections like strep throat or bacterial endocarditis can trigger immune responses that damage the glomeruli. Autoimmune diseases such as lupus or vasculitis cause your immune system to attack kidney tissue directly. Some types run in families and have a genetic component.
Risk factors include recent infections, having autoimmune conditions, diabetes, high blood pressure, and certain medications. Sometimes the cause is never found, called idiopathic glomerulonephritis. Heavy alcohol use and exposure to certain toxins may also contribute to kidney inflammation over time.
How it's diagnosed
Diagnosis starts with a urine test to check for protein and blood. Rite Aid offers microalbumin urine testing to detect early kidney damage before other symptoms appear. This test measures small amounts of the protein albumin leaking into urine, an early warning sign of glomerular disease.
Your doctor may order additional blood tests to check kidney function and look for underlying conditions. Imaging tests like ultrasound can show kidney size and structure. In some cases, a kidney biopsy is needed to determine the specific type of glomerulonephritis and guide treatment decisions.
Treatment options
- Treat underlying infections with antibiotics if bacteria caused the inflammation
- Blood pressure medications to protect kidneys and reduce protein loss
- Immunosuppressive drugs like corticosteroids for autoimmune types
- Diuretics to remove excess fluid and reduce swelling
- Low-sodium diet to help control blood pressure and fluid retention
- Reduce protein intake if kidney function is declining
- Stay hydrated and avoid medications that can harm kidneys
- Regular monitoring with blood and urine tests

Frequently asked questions
Acute glomerulonephritis develops suddenly, often after an infection, and may improve with treatment. Chronic glomerulonephritis progresses slowly over months or years and can lead to permanent kidney damage. Acute cases sometimes resolve completely, while chronic types require ongoing management to slow progression.
Some types of acute glomerulonephritis can be cured, especially when caused by treatable infections. Chronic glomerulonephritis usually cannot be cured but can be managed to slow kidney damage. Treatment focuses on controlling symptoms, addressing underlying causes, and protecting remaining kidney function.
When glomeruli become inflamed, they allow protein and blood cells to leak into urine. A microalbumin urine test can detect small amounts of the protein albumin before visible symptoms appear. Higher levels of protein in urine, called proteinuria, indicate more severe kidney damage that needs medical attention.
Not everyone with glomerulonephritis needs dialysis. Many people manage the condition with medication and lifestyle changes for years without dialysis. Dialysis becomes necessary only if kidneys fail and can no longer filter waste adequately. Early detection and treatment significantly reduce this risk.
Limit sodium to help control blood pressure and reduce fluid retention. Your doctor may recommend reducing protein intake if kidney function declines. Avoid processed foods high in phosphorus and potassium if blood levels become elevated. Working with a dietitian can help you create a kidney-friendly eating plan.
Some types of glomerulonephritis have a genetic component and can run in families. Alport syndrome and IgA nephropathy are examples of inherited forms. However, many types are not hereditary and develop due to infections, autoimmune conditions, or unknown causes. Family history helps doctors assess your risk.
Stress does not directly cause glomerulonephritis but can worsen underlying conditions. Chronic stress may raise blood pressure, which can accelerate kidney damage. Managing stress through exercise, adequate sleep, and relaxation techniques supports overall health. It may also help you stick to treatment plans more consistently.
People with diabetes, high blood pressure, or autoimmune diseases should have urine testing at least once a year. If you have a family history of kidney disease, annual screening is recommended. Your doctor may suggest more frequent testing if you have multiple risk factors or previous kidney problems.
Moderate exercise supports overall health and helps control blood pressure and weight. Both factors protect kidney function over time. Avoid intense exercise during active inflammation, as it may worsen symptoms. Always consult your doctor before starting a new exercise program to ensure it is safe for your specific situation.
Untreated glomerulonephritis can lead to chronic kidney disease and eventual kidney failure. Persistent inflammation damages the glomeruli permanently, reducing their ability to filter blood. High blood pressure and fluid buildup can affect your heart and other organs. Early treatment prevents or slows this progression significantly.
