Hello,

Thanks for posting your query.

The symptoms for excessive urination irrespective of fluid intake and feeling thirsty indicate either deranged blood glucose levels or diabetes insipidus.

You need to visit your physician and get some investigations done - fasting glucose levels, serum electrolytes, serum osmolarity and urine osmolarity.

If you have more queries, I will be glad to answer.
