Thank you for the information.

There can be a few causes for the need to urinate frequently at night.

It can be due to an infection or inflammation, chronic kidney disease.

Diabetes is another cause.

Excess intake of fluid, tea, coffee, alcohol can also cause it.

You can try to drink the fluid more during day & limit tea, coffee, alcohol, if you take.

If that does not help, I would advise to have an examination by doctor again.

A few tests like urine for routine analysis, blood tests, ultrasonography of kidney and bladder can be taken.

I hope this information helps.

I will be happy to assist, if you need any clarification.
