Can a prostate become so enlarged that it causes a hernia

A big prostate does not push through the abdominal wall. But the same plumbing problem behind it can cause the groin hernia.

The link is pressure, not size. A large prostate narrows the outlet of the bladder. That makes a man strain to push urine out, and years of straining raise pressure inside the belly. A groin or inguinal hernia is bowel or fat pushing through a weak spot in the lower abdominal wall, and that pushing comes from pressure, not from the prostate physically reaching out. The records here do not directly test that pathway in men, so treat it as a plausible mechanism, not a proven number.

One retrieved study does connect the two, but the other way around. It looked at men having prostate surgery and found inguinal hernias appearing afterward, with rates much higher after radical prostatectomy (10%) and radical prostatectomy plus lymph node removal (15%) than after open prostatectomy for benign enlargement (2.5%) [1]. That same record also muddles breast and kidney-stone data, so weigh it carefully [1]. What the surrounding literature tells us about a blocked bladder raising belly pressure is not in these records.

My call: yes, an enlarged prostate can contribute to a groin hernia, but through chronic straining that raises belly pressure, not through the gland's physical size, and the evidence here is indirect. Confidence: low.
