Urinary tract infections (UTIs) are a common health concern among women. The dynamics of female anatomy make them more susceptible to these infections. This is due to the short and petite urethra providing a convenient pathway for bacteria to infiltrate the bladder and urethra. Left untreated, UTIs can escalate, and bacteria may ascend to the kidneys, resulting in a serious condition known as pyelonephritis. Recognizing the symptoms, such as the unmistakable burning sensation during urination and increased frequency of urination, is crucial for timely intervention and effective treatment.
