How long will i need to be treated for my prostate enlargement?

If BPH = lifetime: If the enlargement is from an infection, then treatment only for a short time. But (as in most cases) if the BPH (benign prostatic hyperplasia) is the cause, then you'll need treatment for a lifetime (or as long as you want the benefits that meds give you). That's why many people choose surgery -- it's more invasive than medications, but is much more durable.

See below: Prostate enlargement (aka BPH) begins at ~age 40 and size and symptoms increase with age. The vast majority of men with prostate enlargement will never require treatment. For those men who are either symptomatic and bothered by their voiding symptoms or experience BPH-related complications (urinary retention, recurrent UTIs or bleeding), there a a variety of available medical and surgical options.
