Which of the following is NOT a common symptom of glomerulonephritis?

Glomerulonephritis is a condition characterized by inflammation of the glomeruli, which are small structures in the kidneys that filter blood. Common symptoms associated with glomerulonephritis include hematuria (blood in the urine), edema (swelling due to fluid retention), and hypertension (high blood pressure).

The presence of hematuria occurs because inflammation can cause damage to the glomeruli, allowing red blood cells to escape into the urine. Edema typically results from the kidneys’ impaired ability to filter and excrete excess fluids, leading to fluid accumulation in the body’s tissues. Hypertension can arise as a consequence of the kidneys' response to kidney damage and fluid overload, affecting blood pressure regulation.

In contrast, polyuria, which refers to excessive urination, is not typically a symptom of glomerulonephritis. Instead, patients with this condition more commonly experience oliguria (reduced urine output) due to kidney dysfunction. Therefore, recognizing that polyuria does not align with the typical presentation of glomerulonephritis helps identify the correct answer.
