Peppers, alcohol, and other strong foods can irritate the
prostate and the urinary tract
, so try to avoid them if you think this is causing your problem. Another cause of irritation is constipation and hard stools, which press against the bladder and prostate. Take a stool softener and drink more water if you have hard stools. Take saw palmetto if told to do so by a doctor; this helps with minor prostate enlargement (BPH), but does not treat infections or anything else.
