Proteinuria is a medical term used to describe high levels of protein in the urine. Under normal conditions, people do not have protein in their urine because structures in the kidneys known as glomeruli filter out proteins so that they can be reused by the body.

Of the three pathophysiologic mechanisms (glomerular, tubular and overflow) that produce proteinuria, glomerular malfunction is the most common and usually corresponds to a urinary protein excretion of more than 2 g per 24 hours. When a quantitative measurement of urinary protein is needed, most physicians prefer a 24-hour urine specimen.

Proteinuria is also associated with cardiovascular problems, including high blood pressure, and diabetes, all of which can put strain on the kidneys so that they cannot function normally. Protein in the urine can also be caused by infections and inflammations of the urinary tract.

Some people get more protein into urine while standing than while lying down. That is known as orthostatic proteinuria. Treatment of Proteinuria. Proteinuria is not a specific disease. So its treatment depends on identifying and managing its underlying cause. If that cause is kidney disease, appropriate medical management is essential.

Proteinuria is a common finding in adults in primary care practice. An algorithmic approach can be used to differentiate benign causes of proteinuria from rarer, more serious disorders. Benign causes include fever, intense activity or exercise, dehydration, emotional stress and acute illness.

Doctors refer to this as orthostatic proteinuria because it the protein levels of the urine go up when the child is standing. Strangely, when the child lies down, the protein levels return to normal. We doctors are confused by this phenomenon, and we do not know why it happens.

Proteinuria on initial dipstick urinalysis testing is found in as much as 17 percent of selected populations.1 Although a wide variety of conditions, ranging from benign to lethal, can cause proteinuria, fewer than 2 percent of patients whose urine dipstick test is positive for protein have serious and treatable urinary tract disorders.2 A knowledgeable approach to this common condition is required because the diagnosis has important ramifications for health, insurance eligibility and job ...

Risk Factors for Proteinuria. The two most common risk factors for proteinuria are: Diabetes; High blood pressure (hypertension) Both diabetes and high blood pressure can cause damage to the kidneys, which leads to proteinuria. Other types of kidney disease unrelated to diabetes or high blood pressure can also

In mild or temporary proteinuria, no treatment may be necessary. Drugs are sometimes prescribed, especially in people with diabetes and/or high blood pressure. These may come from two classes of drugs:

Healthy kidneys do not allow a significant amount of protein to pass through their filters. But filters damaged by kidney disease may let proteins such as albumin leak from the blood into the urine. Proteinuria can also be a result of overproduction of proteins by the body. Kidney disease often has no early symptoms.
