What Complications Can Arise from a UTI?
Urinary tract infections (UTIs) can lead to several complications if not treated promptly and effectively. One of the most common complications is the progression of the infection from the lower urinary tract (bladder and urethra) to the upper urinary tract (kidneys), resulting in pyelonephritis, or kidney infection. This condition is more serious and can cause fever, chills, and severe back or side pain, indicating the infection has reached the kidneys. If a kidney infection is not treated, it can lead to permanent kidney damage or sepsis, which is a potentially life-threatening response to infection affecting the entire body.
Another potential complication of untreated UTIs, particularly in men, is the infection's spread to the prostate gland, leading to bacterial prostatitis. This condition can cause painful or difficult urination, pain in the groin, pelvic area, or genitals, and sometimes flu-like symptoms. Additionally, chronic or recurrent UTIs can lead to scarring in the bladder and urethra, which reduces bladder capacity and can cause frequent urination and other long-term urinary problems. In pregnant women, UTIs can increase the risk of delivering low birth weight or premature infants, highlighting the importance of treating even mild infections during pregnancy.
