Urinary tract infections (UTIs) are common bacterial infections affecting the urinary system, including the bladder, urethra, and kidneys. The choice of antibiotic for treating a UTI depends on several factors, including the type of bacteria causing the infection, the patient's medical history, and any known drug allergies or resistance patterns. Accurate diagnosis through urine tests helps identify the specific bacteria and determine the most effective antibiotic. In some cases, empirical treatment may be started based on common pathogens and local resistance patterns, with adjustments made once test results are available. Proper adherence to the prescribed antibiotic regimen is crucial to fully eradicate the infection and prevent recurrence. Additionally, increasing fluid intake and practicing good hygiene can aid in recovery and reduce the risk of future UTIs.
