UTIs are typically caused by bacteria from the large intestine existing from the anus and entering the urethra (where urine is released from the body). If bacteria do get into the urethra, they can travel through the urinary tract system and develop into an infection.
Women are prone to UTIs for a number of reasons, including:
Anatomy: Because women have shorter urethras than men, the bacteria is able to reach the bladder and kidneys faster, causing higher rates of UTIs.
Genetics: Some women to be naturally predisposed to UTIs due to the shape of their urinary tract.
Hormone changes: Frequent fluctuations in hormones due to women’s menstrual cycles can increase the risk for UTIs.
Other factors which may increase the risk for UTIs include multiple sclerosis, a weakened immune system due to conditions like diabetes, and health issues affecting urine flow, such as kidney stones, stokes, and spinal cord injuries.
