Proteinuria is a key symptom associated with glomerulosclerosis, which is a condition characterized by the scarring or hardening of the glomeruli, the tiny filtering units in the kidneys. When these filtering units become damaged, they lose their ability to effectively filter waste and excess substances from the blood. This results in an abnormal leakage of protein into the urine, known as proteinuria.

In the context of glomerulosclerosis, the presence of protein in the urine can serve as an important indicator of kidney damage and can be a marker used in diagnosing various nephrotic syndromes. The detection of protein in the urine can indicate impaired kidney function, leading to additional complications if not managed properly.

Other potential symptoms like high blood pressure, skin rash, and heart palpitations might be related to broader conditions affecting kidney function or other systemic issues but are not directly indicative of glomerulosclerosis itself. For instance, high blood pressure can result from renal disease but is not specific to glomerulosclerosis, while skin rash and heart palpitations are similarly vague and may not directly connect to glomerular damage. Therefore, proteinuria is the most definitive symptom associated with glomerulosclerosis.
