Prostate enlargement is quite common among male adults who are 50 or older. It often causes various problems in urination, including a weak or slow flowing stream, a feeling of incomplete bladder emptying, and sleep disturbance called nocturia. There are prescription drugs and natural treatments for this prostate problem, which can be used together to help shrink the prostate and solve urination issues associated with an enlarged prostate. Saw palmetto, a well-known natural treatment for prostate problems, is one example that may slow down the enlargement of the organ, though it isn’t usually used for problems with urination.
