What is a common consequence of untreated urinary tract infections?

A common consequence of untreated urinary tract infections (UTIs) is possible kidney damage. When a UTI is left untreated, the infection can ascend from the bladder to the kidneys, leading to a more serious condition known as pyelonephritis, which is an infection of the kidneys. This can result in inflammation and scarring of kidney tissue, potentially causing long-term damage. Kidney damage can lead to complications such as chronic kidney disease, which can have serious implications for overall health.

The other options do not adequately detail the specific health risks associated with untreated UTIs. Kidney stones, while they can arise for various reasons, are not a direct consequence of UTIs. Similarly, decreased metabolism and increased appetite are not recognized complications related to untreated urinary infections. Focus on the importance of prompt treatment for UTIs to prevent these severe outcomes emphasizes the need for proper management of urinary health.
