The Prostate and Hormonal Changes
The truth is, around the age of 40, testosterone levels begin to decline in men. Although not as significant and all-encompassing as the hormonal changes women experience during menopause, it does have some definite effects. As testosterone levels decline, there is also an increase in one of its metabolites, called dihydrotestosterone (DHT). This hormone causes overproduction of cells within the prostate gland, which ultimately result in enlargement of these tissues.
Benign Prostate Hyperplasia – BPH
This process is called benign prostatic hyperplasia often simply called BPH. Because the prostate sits beneath the bladder, when inflamed it may put pressure on the urethra, creating a variety of uncomfortable urinary complaints. Quite simply, the enlarged prostate obstructs the flow of urine. This results in symptoms of incomplete emptying of the bladder, dribbling, difficulty starting urination, reduced force of the stream, frequent urination of small amounts, and sometimes the inability to urinate at all. The data varies, but BPH interferes with the urinary system to some degree in up to 80% of men over the age of 60. It is reported that at least 50% of men over the age of 45 have some prostate enlargement, whether it is accompanied by symptoms or not. These numbers characterize benign prostatic hyperplasia as an "epidemic" rather than an isolated health concern that is troublesome to a small group of men.
This year the American Cancer Society estimates that 165,000 men in the US will be diagnosed with prostate cancer and 35,000 will die of it. Presently, the only malignancy killing more men is lung cancer. The overall incidence has soared 39% since 1973. However, prostate cancer is rare before the age of 50. It occurs in at least 50% of men who live to be 80 and beyond, the average age of diagnosis being 73.
Herbal Nutrition for Prostate
The good news is that research on the herb Saw Palmetto has shown effectiveness at inhibiting the effects of dihydrotestosterone – it works ! Since 1983, there have been numerous double-blind trials involving hundreds of patients. All of the studies show that Saw Palmetto extract is effective for both subjective and objective measurements of prostatic enlargement. Although not as widely studied as Saw Palmetto berry, both Nettle and Pygeum have been shown to be effective for symptoms of BPH.
