Understand your values of Proteins in Urine (mg/dl)

What is it and its measure units?

Proteins in urine, often referred to as proteinuria, is a condition where there is an excess of protein found in the urine. Typically, urine contains only small amounts of protein because proteins are usually too large to pass through the kidneys' filtering system. The measure units for proteins in urine are typically in milligrams per deciliter (mg/dl). This test can be a critical part of diagnosing various kidney issues, as healthy kidneys usually remove very little protein from the body.

Which is its function in our bodies?

While proteins play crucial roles throughout the body, including building muscles, repairing tissues, and supporting immune function, their presence in urine isn't a function but rather a signal. Normally, healthy kidneys filter waste products from the blood while retaining components like protein that the body needs. If proteins are found in the urine, it may indicate that the kidneys' filtering systems are damaged or overwhelmed, allowing proteins to pass into the urine, which should not typically occur. Thus, it can serve as an early indicator of potential kidney disease or other systemic conditions.

What happens if we have values out of normal?

If protein levels in urine are out of the normal range, it could be an indication of several health conditions. Elevated protein levels, or proteinuria, may suggest kidney damage or disease, such as glomerulonephritis, diabetic kidney disease, or high blood pressure-related renal damage. In some cases, it might indicate urinary tract infections (UTIs), systemic diseases like lupus, or even urinary tract blockages. Persistent or severe proteinuria may lead to further health complications, including kidney failure over time if left unchecked. Thus, it’s critical to investigate elevated levels promptly and address the underlying causes.

Which are its optimum values and what should we do to improve our values of this substance?

Ideally, the amount of protein in urine should be very low, typically less than 150 mg/d in a 24-hour period of urine collection, or up to 10 mg/dl when measured in a random urine sample. To maintain or work towards these optimum values, it’s essential to manage conditions like diabetes and high blood pressure effectively, as these can contribute to elevated protein levels. Eating a balanced diet, staying hydrated, and maintaining a healthy weight can also be beneficial. Regular exercise and avoiding smoking can support kidney health, potentially reducing the risk of developing conditions that cause proteinuria. If you're concerned about your levels, it may be necessary to consult with a healthcare provider for a tailored approach.
