Diabetes mellitus in patients with benign prostatic hyperplasia.

Of 51 patients submitted to operation for benign prostatic hyperplasia three (5.9%) were knwon, diabetics and two others had undergone surgery for peptic ulcer. Of the remaining patients half (23 out of 46) were found to be diabetic; 40% (20 patients) had a history of previous cardiac infarction or electrocardiograph evidence of myocardial ischaemia.It is suggested that these findings add further support to the hypothesis that benign prostatic hyperplasia is one manifestation of a relative increase of oestrogen secretion with advancing age.
