This is the primary cause of enlarged prostate. Though males younger than forty years rarely have BPH, nearly more than 50% of elderly males (at age >60 years old) suffer symptoms of enlarged prostate. And this you cannot control from happening.
Usually, you are more susceptible of having enlarged prostate if your father or one of your family had experienced it.
In fact, a positive family history is a very strong predisposing factor for BPH that you cannot control.
This is one of the unexplained, controllable causes of enlarged prostate; but it is found that married men most commonly develop enlarged prostates.
If you are American or European man, then you are at high risk of having BPH. Asian men are less frequently affected. This uncontrollable factor is true and not yet explained.
Many metabolic disorders, like abdominal obesity, increased fasting blood glucose level, diabetes type 2 and elevated blood pressure are usually accompanied with high risk for enlarged prostate.
If you prevent this conditions from setting, you may control enlarged prostate onset too.
Health Professionals Follow-up Study suggests that reasonable alcohol drinking and quitting smoking can limit the enlarged prostate onset.
It is proved that a diet containing more calories can directly influence the chemical structure of androgens. This can definitely influence the prostatic growth. It is also found that physical activity enhances the chances to develop BPH.
That's why if you can take good control of your diet and try to be physically active, you may prevent BPH onset.
Furthermore, scientists have hypothesized myriad theories to what causes of enlarged prostate are:
By aging, naturally testosterone become less produced, this will change the normal balance between 2 hormones. Some animal clinical researches have proved that the increased amounts of estrogen can trigger the development of enlarged prostate.
Naturally, testosterone is transformed to a more potent form called dihydrotestosterone (DHT), which increases the growth of tissues lining your prostate (the glandular epithelium).
Really, DHT is responsible for the fast growth of prostate in the period of puberty (as one of the causes of enlarged prostate in young men).
Studies suggest that older men produce large amounts of DHT. Therefore, DHT is the major suspect of causing enlarged prostate in elderly.
Occurrence of faulty cell apoptosis (programmed cellular suicide); this theory suggests that abnormal prostatic cellular proliferation occur due to defect in cell natural self-destruction.
These can aggravate growth of prostatic cells. What really supports this theory is the presence of many cardiovascular problems in elderly men suffering from enlarged prostate.
In conclusion, the enlarged prostate is normal with aging, you must contact your doctor immediately if you have one or all of below signs:
In order to determine what causes enlarged prostate, your doctor will ask you to tell him/her your complete medical history, and to describe exactly what your symptoms are.
A digital rectal examination will be done gently by your doctor to evaluate the enlargement of your prostate. Some other tests will be done too, including:
