Lupus is a chronic autoimmune disease that can involve any part of the body or organs inside the body. Elevated protein in urine may indicate that lupus has involved your kidney.
Your kidney is the most serious organ involved in lupus, but kidney damage usually occurs silently. If it is caught in time, kidney inflammation can be treated successfully to stop it from developing into Kidney Failure.
Elevated protein urine is the most common symptom of kidney problem. In early stage, you can not notice protein in urine, but test can help detect it. As the kidney damage becomes more severe, more protein will be passed out in urine. You may notice foams in urine. When this happens there, there is a tendency to ankle swelling, to fluid retention and to general fluid "bloating"
When the kidney is inflamed, the blood pressure frequently rises. When the kidney is more severely damaged, the filtering function of the kidneys will be affected. As a result, toxins such as urea, creatinine etc will build up in blood, leading to weight loss, nausea and general malaise.
To decide whether there is elevated protein in urine, urine test is required. A urine test checks different components of urine, a waste product made by the kidneys. Protein is normally not found in the urine. Inflammation of kidney can cause elevated protein in urine.
Additionally, more information concerning kidney function is obtained from simple blood tests. The three main blood tests are affected by kidney function are the blood urea, the creatinine and the albumin.
In some patients, the only way of determining precisely the degree of kidney damage is to perform a kidney biopsy. It is an invasive procedure in which some tissue is removed from kidneys.
If you are a lupus patient and are experiencing elevated protein in urine, it is important for you to seek for treatment immediately.
