The severity of the disease can be reflected by the changes in the tongue. A light red tongue and white, thin, and moist tongue coating are all signs of a mild disease; a red tongue, blue-purple tongue, yellow, thick, and gray tongue coating. , or smooth and coatless, are all signs of a serious condition; pale and white tongues are more common in chronic diseases, such as anemia, protein deficiency, or adrenal insufficiency; red and crimson tongues are more common in diseases such as fever, dehydration, and fluid balance disorders; cirrhosis of the liver If the patient's original pale red tongue, thin white coating or thin yellow coating turns to red and peeling, it means that the liver function has deteriorated. Acute appendicitis is more common with greasy coating. During the treatment process, the thick greasy coating turns to thin white coating, which usually means that the condition has improved, but if the patient is in pain If it is relieved but the greasy coating does not go away, it means that the condition has not improved, or may even worsen.
Changes in tongue appearance also have certain significance in the diagnosis of certain diseases. A large amount of clinical practice has proved that the nature of the disease, the depth of the disease, the progression and regression of the disease, as well as the judgment of the outcome and prognosis of the disease can all be reflected from the changes in the tongue. It can be said that the tongue changes vividly and rapidly. It is like a mirror of the internal organs, which can reflect the condition more objectively and is an important basis for doctors to diagnose diseases.
Tongue diagnosis of traditional Chinese medicine has also had a great impact on Western medicine. Western medicine diagnostics also gradually pays attention to changes in tongue quality, tongue coating, and tongue activity. For example, patients with hyperthyroidism often experience tremors when their tongues are extended; patients with acromegaly and myxedema have enlarged tongues; in hypohemaemic anemia, the tongue surface is smooth; in riboflavin deficiency, the tongue epithelium may have irregular bulges. ; The tongue of patients with scarlet fever is bright red and shaped like a strawberry. These diseases, which are considered to be important organs of the human body in traditional Chinese medicine diagnostics, can all react on the tongue. The patient's condition, changes and prognosis can be understood through tongue diagnosis. Because tongue diagnosis in traditional Chinese medicine is very important, many countries in the world are conducting in-depth research. They use tongue fluorescence examination, tongue print examination, tongue pathological biopsy, tongue intravital microscopic observation, tongue scraping smear examination, and various Physiology, biochemistry, hemorrheology measurement, etc., explore the secrets of tongue diagnosis, so that the ancient Chinese medicine tongue diagnosis can make greater contributions to world medicine.
