UTIs and prostatitis can have overlapping symptoms but are fundamentally different conditions. UTIs are infections of the urinary tract that are usually caused by bacteria like E. coli, while prostatitis is inflammation of the prostate gland that can be caused by bacterial or non-bacterial factors. Prostatitis may cause symptoms beyond urinary issues like abdominal, back, or groin pain and sexual dysfunction. UTIs typically show abnormalities in urine tests, but prostatitis diagnosis requires additional examinations and treatment can be more complex, sometimes requiring traditional Chinese medicine instead of antibiotics alone. It is important for men not to self-diagnose but to see a medical professional for accurate diagnosis and treatment of UTIs or prostatitis.
