What to know
Benign prostatic hyperplasia (BPH) is noncancerous enlargement of the prostate. It can contribute to frequent or urgent urination, nighttime urination, difficulty starting, a slow or weak stream, and incomplete bladder emptying. These symptoms are not specific to BPH, so diagnosis matters.
Evidence and treatment context
NIDDK describes established BPH management as including watchful waiting, lifestyle changes, medicines, and surgery depending on symptoms and clinical circumstances. For supplements, evidence is ingredient-specific and often limited. NCCIH says saw palmetto alone probably does not improve BPH urinary symptoms; evidence for pygeum is limited and based substantially on small, short studies.
