This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
This is not likely related to fatty liver condition.
Excessive thirst can be caused by the high blood sugar or diabetes commonly.
Fasting blood sugar should be checked alon with hemoglobin A1c level.
Another possibility can be due to the ADH hormone abnormality either in the pituitary gland in the brain or at the kidney level.
ADH helps to concentrate the urine and hence preservation of body fluids.
When there is low level of ADH or ADH is not able to act on the kidneys normally excessive thirst issue may arise.
Hence, you need further evaluation by a specialist.
You can try an endocrinologist for full work up.
It was my pleasure to help you today.
