my daughter in law is suffering from an illness that has yet to be diagnosed. She is constantly thirsty, urinates alot, has vaginal problems, dry eyes , anxiety , and weight loss . The doctors have ruled out diabetes through test, but have indicated that it might be something like diabetic - something. She was not sure what they said and she will have more test tomorrow after fasting from drink. The doctor told her it is treatable, but that it not diabetes. Can you make any sense of this and help us figure out what it might be.
