Hello~Niko has given you some very good advice. I agree, I don't believe that gall bladder issues effect the frequency of urination. I suspect that this could be due to a blood sugar disorder.
I hope you get the relief you need soon. God bless you.
It is likely a separate issue and not related directly to gallstones.
Make sure you rule out diabetes, Urinary track infection
and kidney problems which could be underlying conditions causing the frequent urination.
If the volume is higher (not just frequency) it could have to do with possible blood sugar issues.
For males, it's wise to also rule out prostate-related conditions.
I hope this helps,
Niko
