Urology/Frequent urination at night - slow digestion


Hi there,

I am a 34 year old male with an odd condition: some days, if I eat in the evening after a certain time, my digestion is extremely slow, so that I go to bed with the feeling of a very full stomach. Every time this happens, I have to wake up at night to urinate two or three times and have awful nightmares. I have been having this for some years now and never found any advice or a similar case in the extensive research I did on the internet.  Doctors I saw denied a correlation between the digestion issue and the nocturia and thought simply that I was drinking too much liquid at night, which is not the case. They said that this is a condition not known to western medicine.
Suspicion of diabetes was promptly dismissed after urine tests. The odd thing is that this never happens during day time, only at night. I know that certain foods trigger this condition with certainty,for example potatoes, some not. It seems as if my body would be trying to get rid of some toxin through urination, but how to explain that it only happens at night?
I do not drink neither coffee nor alcohol and do not have symptoms of a benign prostata hyperplasia nor of prostatitis.
What could be causing this and is there a way to treat this issue?

Thanks a lot for your help.


There is no specific condition that causes your particular combination of symptoms. Nocturnal can be caused by fluid issues, bladder overactivity, sleeping disorders and a lack of ADH at night. There us nit enough info provided to differentiate these in your notes start by doing a voiding diary where you write down the time and amount of voiding for 24 hours. If nighttime amounts are small, overactivity is suggested,but if amounts arelarge,then it's more likely to be a fluid management issue. Talk to your urologist.
