The prostate is a gland unique to men that produces prostate fluid, and the prostate is rich in local blood flow. If the body drinks alcohol it will lead to a higher local alcohol concentration than other tissues, so local congestion and edema will occur, even leading to an increase in the size of the prostate. If the patient does not have any underlying disease, drinking alcohol will lead to local congestion of the prostate gland. If there is prostatitis, drinking alcohol will aggravate the progress of prostate disease. If you have an enlarged prostate, drinking alcohol causes the body to be unable to urinate on its own due to the increase in prostate volume, which means acute urinary retention.
