Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in the size of the prostate gland. Symptoms may include frequent urination, trouble starting to urinate, a weak stream, inability to urinate, or loss of bladder control. Complications can include urinary tract infections, bladder stones, and chronic kidney problems. The cause is unclear.
Risk factors include family history, obesity, DMT2, not enough exercise, and ED. Medications like pseudoephedrine, anticholinergics, and calcium channel blockers may worsen symptoms. The underlying mechanism involves the prostate pressing on the urethra thereby making it difficult to pass urine out of the bladder.
Diagnosis is typically based on symptoms and examination after ruling out other possible causes.
