How can dehydration cause UTI

Dehydration may result in UTI in the following ways:

Infrequent urination

Dehydration occurs when a person intakes less water than the body’s requirement.

As a result, there is a significant decline in the frequency of urination, and the person may not naturally flush out the infectious bacteria.

It enables bacteria to stay in the bladder for longer and cause UTIs.

Concentrated urine

Dehydration results in concentrated and less urine formation.

Also, concentrated urine is an ideal medium for bacterial growth as the bacteria increase in number and cause infections in the urinary tract. 

Fact:
