Presence of protein in urine is a condition which is known as proteinuria in medical parlance. It is sometimes also referred to as albuminuria or micro albuminuria. Let us discuss the significance of this condition.
It is the job of our kidneys to filter our blood. While the toxins present in it are discarded in the form of urine, the essential components are retained back. However, in certain conditions, the kidneys fail to retain all the protein present in blood. Some amount of it may then pass into urine giving rise to proteinuria.
In early cases, proteinuria may remain undetected. However, as more and more amounts of protein are passed into urine, the urine may appear to be frothy. Deficiency of protein in the body may give rise to swelling in the upper and lower limbs and on the face. In case of any of these symptoms, one must consult his physician immediately.

In both these conditions, protein in urine may be the earliest sign of damage to kidneys. If left untreated, the damage to kidneys may become progressive leading to chronic renal failure.
Protein in urine is just a symptom of underlying medical pathology. Treatment depends upon treating the cause. In case of people suffering from diabetes or high blood pressure, two classes of medicines are generally prescribed to halt the damage to kidneys. These include:
In case the damage to kidneys is not checked in the initial stage, it may lead to chronic renal failure, where dialysis or kidney transplant are the only options left to save the life of the patient.
