Protein Leakage in Urine: Causes and Symptoms
Protein leakage in urine, also known as proteinuria, is an abnormal concentration of protein in the urine and can be caused by a variety of reasons. Normally, kidneys filter waste from the body, and only a small amount of protein ends up in the urine. However, some conditions can disrupt this process and cause an excess of protein in the urine.
The glomerular filtration barrier (BFG) plays a vital role in filtering the blood to remove waste products in the urine while preserving beneficial components such as protein. BFG has two functions: It allows water and low molecular weight molecules to pass through, and it prevents the passage of high molecular weight molecules. Usually, the proteins do not pass through the BFG.
The symptoms of urine leakage are edema in the genital lips in women and the scrotum in men and a swollen abdomen due to the accumulation of large amounts of fluid in the abdominal cavity. Shortness of breath may also develop as fluid collects in the area around the lungs. Additionally, the loss of nutrients in the urine can cause nutritional deficiencies, calcium loss from bones, and people becoming deficient in vitamin D.
Several factors can cause temporary proteinuria, such as extreme temperatures, emotional stress, financial effort, and fire. Still, these factors usually do not cause harm to the functioning of the kidney, and the urine should return to normal once the cause is eliminated.
Protein overflow in the urine can occur when there is an increased production of low molecular weight proteins that can pass through the glomerulus. This condition creates an increased load on the proximal coiled tubes to reabsorb the protein and results in an increased concentration of excreted proteins.
In conclusion, it is essential to seek medical attention if you experience any of the symptoms mentioned above. Early detection and treatment of proteinuria can help manage the underlying condition and prevent any further complications.
