This is Dr. David
I am another expert here. with ketones in the urine and wanting to drink all the time and pee all the time, she could have diabetes. I know she has had her sugars checked, but she needs a glucose challenge test and a hemoglobin a1c level to check for diabetes or prediabetes.she could also have a fungal thrush infection in her mouth. does she have a white coating on her tongue?
fur feeling on the tongue could be from acid reflux up her throat or bacterial infection of her mouth , sometimes from gingivitis. she could also have an autoimmune disorder as wellher thyroid hormone levels need to be checked as wellhave all of these been checked?
