Proteinuria: Causes, Signs, and Symptoms
Proteinuria is a condition in which an abnormal amount of protein is present in the urine, often indicating underlying kidney dysfunction or systemic health issues.
The causes of proteinuria can vary widely, ranging from temporary conditions to chronic diseases. Common causes include:
Kidney disorders such as Chronic Kidney Disease and Glomerulonephritis
Systemic conditions like Diabetes Mellitus and Hypertension
Infections, fever, or intense physical activity (temporary proteinuria)
Autoimmune diseases such as Lupus
Dehydration or prolonged stress
In many cases, proteinuria may not cause noticeable symptoms in its early stages. However, as it progresses, individuals may experience:
Swelling (edema), especially in the hands, feet, abdomen, or face
Shortness of breath (in severe cases)
Unexplained weight gain due to fluid retention
Early detection of proteinuria is important, as it can be a warning sign of kidney damage or other systemic conditions. Regular screening and clinical evaluation help identify the underlying causes of proteinuria and guide appropriate treatment.
