Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland.[1] Symptoms may include frequent urination, trouble starting to urinate, weak stream, inability to urinate, or loss of bladder control.[1] Complications can include urinary tract infections, bladder stones, and chronic kidney problems.[2]
The cause is unclear.[1] Risk factors include a family history, obesity, type 2 diabetes, not enough exercise, and erectile dysfunction.[1] Medications like pseudoephedrine, anticholinergics, and calcium channel blockers may worsen symptoms.[2] The underlying mechanism involves the prostate pressing on the urethra and thereby making it difficult to pass urine out of the bladder.[1] Diagnosis is typically based on symptoms and examination after ruling out other possible causes.[2]
Treatment options include lifestyle changes, medications, a number of procedures, and surgery.[1][2] In those with mild symptoms, weight loss, exercise, and decreasing caffeine intake are recommended, although the quality of the evidence for exercise is low.[2][4] In those with more significant symptoms, medications may include alpha blockers such as terazosin or 5α-reductase inhibitors such as finasteride.[1] Surgical removal of part of the prostate may be carried out in those who do not improve with other measures.[2] Some herbal medicines that have been studied, such as saw palmetto, have not been shown to help.[2] Other herbal medicines somewhat effective at improving urine flow include beta-sitosterol[5] from Hypoxis rooperi (African star grass), pygeum (extracted from the bark of Prunus africana),[6] pumpkin seeds (Cucurbita pepo), and stinging nettle (Urtica dioica) root.[7]
About 105 million men are affected globally.[3] BPH typically begins after the age of 40.[1] Half of males age 50 and over are affected.[2] After the age of 80, that figure climbs to as high as about 90% of males affected.[8][9][1] Although prostate specific antigen levels may be elevated in males with BPH, the condition does not increase the risk of prostate cancer.[10]
