Re: Urinary Problem - January 2010 to Present

You are right that this can be sugar diabetes, but I doubt diabetes insipidus (DI).  Since DI involves a lack of antidiuretic hormone (ADH, vasopressin) you would be urinating a lot, but with more of a full bladder each time.  But you can still have these checked with a fasting glucose and ADH levels.

Another possibility I can think of is interstitial cystitis.

Prostate issues are unlikely since the digital exam and PSA counts were both normal.

Prostate infection is possible, but again unlikely.  Infections will generally result in swelling, which again would be detected by the digital exam.

As for hemorrhoids there are a number of causes including lack of fiber in the diet, lack of silica or vitamin C, straining while having bowel movements or lifting, portal vein congestion, etc.
