Hi. Welcome to JustAnswer. I shall try my best to assist you while you are corresponding with me.
At his age, having nocturia means that he should have some conditions ruled out.
He should have his sugar levels checked and also have urinalysis done to rule out any problems with the urinary tract.
Seeing an internist will be the best course of action at this point in time and after the relevant investigations and when a narrow differential diagnosis is established, he can be referred to a suitable specialty.
Let me know if you have more queries or require more information.
does it look like he has kidney or diabetes problem?
