What is one consequence of untreated kidney infections?

Untreated kidney infections, also known as pyelonephritis, can lead to potential kidney damage. This occurs because the infection can cause inflammation and scarring of kidney tissues, ultimately impairing their function. Over time, if the infection is not resolved, it may lead to chronic kidney disease or even kidney failure, highlighting the critical importance of prompt treatment for kidney infections. Early intervention helps prevent these severe complications and preserves kidney health.

The other options do not accurately reflect the consequences of untreated kidney infections. For example, improved kidney function is contrary to what occurs, and while diabetes can have various risk factors, it is not directly caused by kidney infections. Decreased production of insulin is unrelated to kidney infections as insulin is primarily produced by the pancreas.
