Urinary tract infections (UTIs) are bacterial infections that can occur anywhere along the urinary tract, which includes the bladder, kidneys, ureters, and urethra. Common symptoms of a UTI include a burning sensation when urinating, the need to urinate more often, cloudy or bloody urine, and pain or pressure in the lower abdomen. Risk factors for UTIs include sexual activity, pregnancy, menopause, diabetes, and a weakened immune system. Diagnosis of a UTI is made through a physical examination, urine culture, and urinalysis. Treatment typically involves antibiotics, although home remedies and lifestyle changes may also be recommended.
