<<Disclaimer: Verify this information before applying it to your situation.>> Hello Friends....I am a 36 year old biopsy diagnosed Celiac. Unfortunantly it was not until 2 years ago (35 yrs old) that it was discovered. Much damage had already been done. I also have a bad liver and am waiting on a liver transplant. Everytime I go see my local doctor he has me stick my tongue out. He seems to be checking out the color. I know it is a silly question but curiosity has the best of me. I would appreciate any response. Thanks Gang, Debbie
