Nocturia - how many is too many?

With nocturia in people who have uncontrolled blood sugars, how many times does one tend to go?

And is it more to do with the amount of urine produced, rather than the number of times?
 
Nocturia doesn't only occur in those with high blood glucose.
It can be caused by a number of conditions.
But if you have high blood glucose there are plenty of other reasons to get it down.

High blood sugars cause large volumes of urine to be produced through an osmotic effect when the kidneys can't manage to reabsorb all the glucose and it spills over into the urine. (The word diabetes is from the Greek for siphon.)

It doesn't? I thought the whole reasoning is that because of the excess glucose, the body can't deal with it so you produce more urine. Would you produce more in the day too?

Yes, you would continue to produce large volumes of urine (polyuria) all the while blood glucose levels were above the renal threshold for glucose which is usually around 10 mmol/l. During the day we may not notice needing to empty the bladder more frequently but people are more likely to notice the problem at night as they have to wake up. Normally we secrete a hormone at night that reduces urine output and this allows us to get a full night's sleep. The osmotic effect of glucose lost in urine stops the hormone from having its usual effect and the bladder will easily fill up within 8 hours, hence night-time wakening.

There are other causes of nocturia:- https://patient.info/doctor/nocturia

Ok so would you say prior to diagnosis, more people have nocturia or polyuria or both?

I don't know. Some people have neither. If you have symptoms of nocturia I would see your GP. It would be helpful if you make it clear whether you're a) going frequently but producing relatively small amounts of urine or b) producing large amounts of urine. If it's the latter, it would be helpful to say if you think you are only producing large amounts of urine at night and normal amounts during the day.
