An enlarged prostate

Eventually, an enlarged prostate can squeeze down on the small tube that transports urine from the bladder out of your penis and restrict the flow of urine.

This can lead to problems

While the symptoms of BPH may be mild to moderate at first, it can have a significant impact on your quality of life. Left untreated, BPH may lead to bladder, urinary tract or kidney problems.4
