In mild urinary tract infections, it is possible to achieve self-healing by drinking more water and maintaining a clean urinary tract by flushing the urinary tract with urine. The general observation period is about 72 hours, or 3 days. However, if the urinary tract infection does not heal on its own after more than 3 days, it is recommended to go to the hospital for examination and, if necessary, treatment with antibacterial drugs. Drinking more water can produce more urine, which promotes the excretion of urine containing bacteria as soon as possible. At the same time, urine flushes the urinary tract, which can expel the bacteria attached to the mucous membrane of the urinary tract and achieve self-healing. It can often be applied to young and strong men or women, whose organism is relatively resistant, as well as to minor urinary tract infections, that is, infections confined to the lower urinary tract, including infections of the urethra and bladder. However, when upper urinary tract infections occur, even if you drink more water, they will not heal themselves and need to be treated with medication. Upper urinary tract infections, including pyelonephritis and ureteral inflammation, cannot be cured by drinking more water. However, minor urethritis and cystitis can be cured by drinking more water and urinating more often.
