Medications are necessary to treat night-time urination, or nocturia, in women, but men can benefit from a supplement called saw palmetto, according to the Weil Lifestyle. When the male prostate gland increases in size, it presses against the bladder, which leads to frequent urination. Saw palmetto helps shrink the prostate gland.
Benign prostatic hyperplasia, or BPH, leads to an obstruction in the flow of urine out of the bladder, note the Weil Lifestyle. In addition to night-time urination, other symptoms include weaker urine flow, increased dribbling after full urination, difficulty starting to urinate and elevated frequency. The cause of BPH is the long-term impact of testosterone on the prostate, which is normally about the size of a walnut and provides lubricants to coat the interior of the urethra and make a hospitable growing area for sperm.
Taking 160 milligrams of a saw palmetto extract that has been standardized to 85 to 90 percent total fatty acids twice daily should shrink the prostate in a month to six weeks, states the Weil Lifestyle. Some formulations mix saw palmetto with Pygeum africanum, which also protects the prostate and comes from evergreen tree bark. Taking 30 milligrams of zinc picolinate each day may help as well.
