What causes an enlarged prostate?
We don't yet fully understand what causes the prostate gland to grow. However, there are two risk factors that we do know about:
Your risk of developing an enlarged prostate increases as you get older. Many men over the age of 50 will have an enlarged prostate gland but not all will get symptoms.
The balance of hormones in your body changes as you get older and this may cause your prostate gland to grow.
Some studies have shown that obese men and men who have diabetes may be more at risk of developing an enlarged prostate. You may be able to reduce your risk by doing more exercise. However, we still need more studies into the causes of enlarged prostate to know for certain if, and how, we can prevent it.
There is also some research that suggests you may be more at risk of developing an enlarged prostate if your father or brother have the condition. Again, further studies are needed to confirm this.
