Membranous Nephropathy: Causes and Treatments
Membranous nephropathy is a kidney disease that affects the tiny blood vessels in the kidneys called glomeruli. These glomeruli filter waste and excess fluids from your blood to form urine. In membranous nephropathy, the walls of the glomeruli become thickened due to the buildup of immune deposits. This thickening can interfere with the kidney's ability to filter blood properly.
Causes of Membranous Nephropathy
The causes of membranous nephropathy can be divided into two main categories: primary and secondary.
Primary Membranous Nephropathy
Primary membranous nephropathy, also known as idiopathic membranous nephropathy, occurs without an identifiable cause. It is believed to be an autoimmune disorder, where the body's immune system mistakenly attacks the kidneys.

Secondary membranous nephropathy occurs as a result of other conditions or factors, such as:
- Infections (e.g., hepatitis B, hepatitis C)
- Certain medications (e.g., nonsteroidal anti-inflammatory drugs, gold salts)
- Autoimmune diseases (e.g., lupus)
- Cancers (e.g., lung, colon, breast cancer)
Symptoms of Membranous Nephropathy
The symptoms of membranous nephropathy can vary, but the most common ones include:
- Swelling in the legs, ankles, or feet
- Foamy urine (due to excess protein in the urine)
- Weight gain (from fluid retention)
- Fatigue
- High blood pressure
Diagnosis of Membranous Nephropathy
To diagnose membranous nephropathy, your doctor may perform several tests, including:
Urine Tests
Urine tests are used to check for proteinuria (excess protein in the urine), which is a common sign of membranous nephropathy.
Blood Tests
Blood tests can help determine how well your kidneys are functioning and check for other conditions that might be causing your symptoms.
Kidney Biopsy
A kidney biopsy involves taking a small sample of kidney tissue to examine under a microscope. This can help confirm the diagnosis and determine the extent of the disease.
Treatment of Membranous Nephropathy
The treatment for membranous nephropathy depends on the severity of the disease and its underlying cause. Here are some common treatment options:
Medications
- Immunosuppressants: These medications can help reduce the immune system's attack on the kidneys.
- Corticosteroids: These can help reduce inflammation in the kidneys.
- ACE inhibitors or ARBs: These medications can help lower blood pressure and reduce proteinuria.
Lifestyle Changes
- Diet: A low-sodium, low-protein diet can help reduce swelling and proteinuria.
- Exercise: Regular physical activity can help maintain a healthy weight and blood pressure.
- Quit smoking: Smoking can worsen kidney function, so quitting is essential for managing membranous nephropathy.
Membranous Nephropathy Diet
A healthy diet is crucial for managing membranous nephropathy. Here are some dietary recommendations:
Low-Sodium Diet
Reducing sodium intake can help control blood pressure and reduce swelling. Aim for less than 2,300 milligrams of sodium per day.
Low-Protein Diet
A low-protein diet can help reduce the workload on your kidneys. Consult with a dietitian to determine the right amount of protein for your needs.
Fruits and Vegetables
Eating a variety of fruits and vegetables can provide essential vitamins and minerals while helping to maintain a healthy weight.

Book an AppointmentManagement and Monitoring
Managing membranous nephropathy involves regular monitoring and follow-up with your healthcare team. This may include:
Regular Check-ups
Regular check-ups with your nephrologist (kidney specialist) are essential to monitor kidney function and adjust treatment as needed.
Blood Pressure Monitoring
Keeping your blood pressure under control is crucial for preventing further kidney damage. Aim for a blood pressure of less than 130/80 mm Hg.
Monitoring Proteinuria
Your doctor may recommend regular urine tests to monitor protein levels and adjust treatment as needed.
