The prostate is a gland which sits under the bladder in men. It also surrounds the urethra – the tube through which urine passes out of the bladder when you urinate.
As the prostate enlarges, it presses against and puts pressure on the bladder. This has the effect of ‘irritating’ the bladder, giving rise to what doctors call ‘irritative symptoms’.
At the same time, an enlarged prostate can also ‘squeeze’ the urethra, making it more difficult for urine to flow out of the bladder. This gives rise to ‘obstructive symptoms’.
In general, symptoms of an enlarged prostate affect men from the age of 45 onwards. So, if you are in your 30s, it is unlikely that you will suffer from an enlarged prostate, even if you experience some of the symptoms described on this page.
