The PSA indicates the general health of one's prostate. It is measured through the PSA test. Since the PSA is normally present in very small amounts in the blood, an elevated PSA level would mean an incidence of a prostate disease.
It is usual for urologists to prescribe antibiotics to lower the PSA and recommend another PSA test after a period of time usually 3-6 month's interval. PSA will usually drop if infection is present. However, if there is no infection, or in cases where the infection does not respond to the antibiotic, then the PSA will not change or will continue to rise after the medication. Also, antibiotics have side effects, which is common to all medicines. These can be as mild as a simple headache or as severe as diarrhea.
Research shows that natural ways to improve the general health will ordinarily result to lower PSA levels. A properly-balanced diet that contains a wide variety of vitamins and antioxidant-rich fruits and vegetables will promote a healthier prostate. Animal fats and protein, highly refined and fried foods and dairy products should be avoided. This is because animals that are grain-fed are suspected to be given antibiotics; therefore, it is believed that their meat and excretion, including eggs and dairy products, must contain traces of these antibiotics that are harmful to human consumption. The same is true with pesticides and other chemicals sprayed on plants, hence it is important to choose organic and natural produce.
Supplementation is also a key to lowering the PSA level. Natural supplements that are rich in vitamins D, E and C and minerals such as selenium also support a healthy prostate.
It is also important for the body and the prostate to receive ample amounts of exercise and movement. However, biking and other sorts of riding should be done in moderation as these activities could impact the prostate.
