The cause of prostate enlargement is still unknown, but it is believed to be linked to hormonal changes that occur as men age. The body's hormonal balance shifts as you get older, and this can lead to an increase in prostate size. It is not fully understood what causes the prostate to enlarge, but it could be due to alterations in the balance of sex hormones as men age. For many men, an enlarged prostate is a natural part of the aging process, similar to wrinkles.
The exact causes of prostate enlargement are still unclear, but it may be related to changes in the balance of sex hormones as men age.1 Additionally, there is some research that suggests a role for DHT, a male hormone that helps the prostate grow. Older men tend to have higher levels of DHT. In addition, too much DHT may be the reason for prostate cell growth.6 An enlarged prostate is referred to as benign prostatic hyperplasia (BPH). This occurs when cells in the prostate start to multiply, leading to swelling and tightening of the urethra which restricts the flow of urine.
An enlarged prostate can cause uncomfortable urinary symptoms such as blocking the flow of urine out of the bladder. The intensity of symptoms in people with an enlarged prostate can vary, but they usually worsen gradually over time. Antibiotics may be used if the prostate is chronically inflamed due to bacterial prostatitis related to BPH. In many cases, this continuous growth enlarges the prostate enough to cause urinary symptoms or significantly impede urine flow.
Prostate cancer is usually symptomless and is identified by an increase in PSA or a prostate nodule. Transurethral incision of the prostate (TUIP) is a procedure in which a few small cuts are made in the prostate to reduce pressure on the urethra.
