There are many different conditions that could cause proteins in the urine, and the treatment for each underlying condition is different. So the first step you have to do is to see a nephrologist to find out what causes your protein in urine.
In many cases, proteinuria is caused by relatively benign (non-cancerous) or temporary medical conditions.
These include dehydration, inflammation and low blood pressure. Intense exercise or activity, emotional stress, aspirin therapy and exposure to cold can also trigger proteinuria. In addition, a kidney stone in the urinary tract can cause proteinuria.
Occasionally, proteinuria is an early indication of chronic kidney disease, a gradual loss of kidney function that may eventually require dialysis or a kidney transplant. Diabetes and high-blood pressure can damage kidneys and are the number-one and number-two causes of kidney disease.
Other potentially kidney-harming diseases and medical conditions, which can lead to proteinuria, include:
- Immune disorders like lupus and Goodpasture’s syndrome
- Acute inflammation of the kidney (glomerulonephritis)
- Cancer of plasma cells (multiple myeloma)
- Intravascular hemolysis, which is the destruction of red blood cells and release of hemoglobin in the bloodstream
- Cardiovascular disease
- Preeclampsia, the simultaneous development of hypertension and proteinuria in a pregnant woman
- Kidney cancer
- Congestive heart failure
Also, most serious illnesses can result in proteinuria.
Treatment depends on the underlying condition that caused proteinuria. Each condition requires different treatments.
