The prostate gland in a man begins to grow in size after 40 years of age quite naturally, and this is known as benign prostatic hyperplasia abbreviated as BPH. Now the problem arises when the enlargement of the prostate is more than normal along with symptoms as mentioned below.
In men, the urine flows through the urethra from the bladder. An abnormally enlarged prostate sometimes blocks the flow of urine through the urethra. The cells of the prostate slowly multiply to cause it to enlarge. This puts pressure on the urethra thereby giving rise to a number of problems, most of which manifest as symptoms.
