Kidney infections are the primary type of infection known to cause high protein in the urine (proteinuria).
When you have a kidney infection, also known as pyelonephritis, the infection can damage the kidney's filtering units (glomeruli). These units normally prevent large molecules like protein from leaking into the urine. When damaged, they become less effective, allowing protein to pass through and appear in your urine.
Here's a more detailed breakdown:
- Kidney Infections (Pyelonephritis): These infections directly affect the kidneys and their ability to filter blood properly. The inflammation and damage can lead to proteinuria.
While kidney infections are the most direct cause, other infections can indirectly contribute to high protein in urine by impacting kidney function or overall health:
-
Infections that cause Sepsis: Severe infections can sometimes lead to sepsis, a life-threatening condition where the body's response to an infection spirals out of control. Sepsis can damage multiple organs, including the kidneys, potentially leading to proteinuria.
-
Infections Associated with Glomerulonephritis: Certain infections, such as strep throat (caused by Streptococcus bacteria) can trigger glomerulonephritis, an inflammation of the glomeruli. While not a direct kidney infection, the inflammation damages the filtering system and causes proteinuria.
It's important to note that proteinuria can also be caused by conditions other than infections, such as diabetes, high blood pressure, and certain medications. If you have high protein levels in your urine, it's crucial to consult a healthcare professional for proper diagnosis and treatment.
