Hammerman,
Urology nurse here. Diabetes should be excluded.
However, prostate issues are a real possibility here:
Nocturia - pee-ing frequently at night
Occasional low urine volumes - could indicate incomplete bladder emptying possibly due to prostate enlargement
Your age: at 44 you are well within the age range for prostate issues.
Get your PSA (Prostate Specific Antigen) checked. It's a simple blood test and your GP can do it. In addition to Sqad's post, yes raised PSA levels can be indicative of prostate cancer however, benign enlargement will also elevate PSA levels. Prior to the blood test, abstain from any activities that will stimulate the prostate for 72 hours prior to the test (eg ejaculation). This will give a truer result.
Let us know how you get on!
