Glomerulonephritis refers to a group of conditions in which the kidney’s filtering units (glomeruli) become inflamed. Below is general information on common signs, how it is evaluated, and which specialists are typically involved. This is educational content, not personalized medical advice.
What it is and common types
Glomerulonephritis is not a single disease but several patterns of glomerular inflammation. Forms include acute and chronic presentations and named subtypes such as post‑infectious, minimal change, membranous, and rapidly progressive glomerulonephritis. Each subtype has a different course and outlook, and underlying causes may include immune responses, infections or systemic diseases.
Signs and symptoms to watch for
Typical features include blood in the urine (dark or pink‑tinged), foamy urine suggestive of protein loss, swelling (especially around the ankles and eyes), rising blood pressure and general fatigue. Symptoms vary by person and subtype. Sudden severe breathlessness, rapidly increasing swelling, marked drop in urine output, or major changes in alertness are more serious and warrant urgent medical assessment.
How glomerulonephritis is evaluated
Evaluation usually starts with a clinical history and physical exam, followed by urinalysis and blood tests to assess kidney function and electrolytes. Immunologic tests and ultrasound imaging may help identify causes. In many cases a nephrologist will consider a kidney biopsy to determine the precise subtype and guide follow‑up.
Monitoring and general management principles
Management depends on the subtype and the degree of kidney involvement. Follow‑up typically includes periodic blood and urine testing, blood pressure monitoring and attention to fluid balance. Dietary and lifestyle measures can support kidney health; the exact plan should be set with a nephrology specialist based on individual findings.
When to seek specialist care or urgent assessment
If you notice persistent blood in the urine, rapidly worsening swelling, uncontrolled high blood pressure, or severe breathlessness, contact a healthcare professional promptly. Initial specialist referral is usually to Nephrology; children are often seen by pediatric nephrologists, and other specialties may be involved if a systemic disease is suspected. For sudden life‑threatening symptoms seek emergency services.
