The condition of the tongue can reflect the health of the body to a certain extent. If the body is healthy, the color and symptoms of the tongue are normal, while some people are very worried about the blackening of the tongue. Therefore, it is very important to know the causes of blackening of the tongue body in time. Let's look at the reasons why the tongue turns black.
1. Diet reasons
The blackening of the tongue coating is most commonly caused by some foods, such as black sesame paste, or drugs, such as iron, which can easily blacken the tongue coating. When your phenomenon may be related to food, but you have taken several drugs recently, it is not excluded that it is a drug factor. If the tongue coating is black, it is related to medication and food. This is only a temporary phenomenon, and it won't happen again. Don't worry.
2. Infected with a high fever
In the process of fever, most people show black hair, and some people have a high fever and retreat, but when they have a fever for the second time, black hair appears again and again, which proves that there is an inevitable connection between fever and the appearance of black hair.
Half of the patients with black fur are caused by various inflammations, including pneumonia, pyelonephritis, gangrenous appendicitis, peritonitis, cholecystitis, phlebitis of lower limbs, suppurative osteomyelitis, pelvic inflammatory disease and septicemia.
3. Gastrointestinal dysfunction
Clinically, more than half of patients with black moss will have gastrointestinal symptoms such as abdominal distension, constipation, nausea and loss of appetite, and gastrointestinal dysfunction is one of the symptoms of body poisoning.
4. Central nervous system dysfunction
When nervous, it will cause the dysfunction of the central nervous system and increase the acidity in the mouth, which is conducive to the growth of chromogenic mold and the appearance of black moss.
5. Mold infection
In people's mouth, there are all kinds of microorganisms, such as bacteria and molds, which restrict and promote each other at ordinary times, maintaining an inevitable balance and not hindering people's health. If a large number of broad-spectrum antibiotics are used to treat diseases, the balance of these microorganisms will be broken.
Some bacteria that are sensitive to antibiotics are killed, while molds that are relatively not afraid of these antibiotics multiply. Because mold can produce various colors, it can appear on the tongue, from brown to dark black.
6. Critically ill patients
Some chronic visceral failure, such as severe liver injury in the late stage of liver cirrhosis, chronic renal failure and uremia, and various advanced cancers, lead to extreme weakness and black tongue coating.
