With the popularization of health preservation, more and more people begin to observe some changes in their bodies, among which the changes of tongue coating are more obvious. Tongue is connected with five internal organs through meridians, so the deficiency and deficiency of human viscera, qi and blood, body fluid and the severity of diseases can be objectively reflected in tongue images.

A healthy tongue is pink, with a moist surface, moderate dryness and wetness, and a thin, white and even tongue coating.

However, cracked tongue, root of tongue and thick tongue coating with tooth marks are more common in clinic. According to the theory of traditional Chinese medicine, it is the clinical manifestation of spleen and stomach weakness, spleen deficiency and dampness excess or spleen and kidney yang deficiency.

Traditional Chinese medicine believes that the whitish tongue coating is caused by spleen deficiency, stomach fire and food accumulation, and after the tooth tongue is formed, it proves that the moisture in the body is already very serious, because the moisture stays in the body, the tongue is more likely to store water and moisture, which leads to the tongue swelling and squeezing teeth, thus forming the tooth tongue.

It shows that there are too many phlegm-dampness pathogens in the body, and people with this tongue often have a bad spleen and stomach.

① The tongue coating is thick and greasy, yellow or white, or has a fat tongue and a cracked tongue. When I get up in the morning, my mouth is sticky and it is difficult to improve my bad breath.

② The appetite drops obviously, and eating a little food will lead to obvious satiety and even abdominal distension, which will seriously affect absorption and digestion.

(3) Weight gain is mainly manifested in excess water, food is not easy to digest and remains in the body, which will also lead to weight gain, which is manifested in patients' obesity and fat accumulation in the abdomen and buttocks.

④ The tongue coating becomes thick, white and even greasy.

5 The stool will be deformed, and the whole body will be as painful and uncomfortable as being wrapped in wet clothes. I have no energy to do things and my whole body is weak.

Tongue diagnosis is an important part of traditional Chinese medicine inspection and the basis of syndrome differentiation and treatment. The tongue picture changes rapidly and clearly, which can accurately reflect the ups and downs of human qi, blood and body fluid and the movement.
