What is the cause of a yellow tongue?
This could be caused by smoking, poor diet, recent antibiotic treatment, mild dehydration, poor oral hygeine. In extreme cases a yellowish tongue may suggest excess bile present in the gallbladder or a possible liver disorder. If the tongue is covered by a coating, it may indicate the presence of toxins in the stomach, small intestine or large intestine. If the posterior part of the tongue is coated, it will indicate that toxins are present in the large intestine. If the middle of the tongue is coated, the toxins are present in the stomach and in the small intestine. See your dentist or family physician.
