What causes black mouth?

A black mouth must be a cause of concern, as it is often a sign of disease. First of all, it shows that the person's physical constitution is relatively poor. Such people often have poor appetite and digestive system disorders, which often lead to constipation, diarrhea and other conditions. In addition, black lips may be related to poor blood circulation. The most common disease is some heart disease. When there is a problem with kidney function, this symptom may also be caused.

What causes black mouth?

The first point is that the digestive system is in an abnormal state for a long time.

It will be difficult for the body to excrete toxins, and the toxins in the human body will slowly accumulate. When they reach a certain level, the body will remind people and the symptom of black lips will appear. In addition, digestive system disorders are caused by many reasons, which are generally related to poor eating habits and bad living habits. Therefore, it is recommended to maintain good eating habits and correct living habits in life. Eighty percent of patients with symptoms such as constipation and diarrhea for a long time will experience loss of appetite, which is also a specific manifestation of problems with the digestive system.

The second point is poor or obstructed blood circulation

The lips may also turn black because when the blood circulation in the human body slows down, it will be prone to various cardiovascular and cerebrovascular diseases, such as heart disease, anemia and other diseases. In severe cases, it may also lead to serious diseases such as stroke. Therefore, when the lips turn black, you should go to the hospital for a blood pressure check. In addition, in some colder places, some people will have bluish purple lips due to poor blood flow at the end of the body, so such people should pay attention to keeping warm and eat more blood and qi-enriching foods to promote blood circulation.

The third point is kidney problems

It will also cause the lips to turn black, because when the liver is damaged, it means that the liver function decreases, which will lead to an increase in melanin in the body, resulting in black lips. In clinical studies, the lips of patients with kidney deficiency, nephritis, and uremia are mostly purple-black, while the lips of most patients with chronic adrenal cortex dysfunction are black. Therefore, when the lips appear black, kidney problems should also be checked.

The fourth point is hepatitis B

Patients may also experience black lips. Due to the decline of liver function, hepatitis B patients naturally have increased melanin, which is also a symptom of worsening hepatitis B, especially for patients with chronic hepatitis and cirrhosis. At the same time, they will also have symptoms such as dull, dry face, and dark complexion. Therefore, if hepatitis B patients have black lips, they must go to a regular hospital for examination, find out the cause, and receive treatment to avoid worsening of the condition. If the disease is caused by liver damage caused by the hepatitis B virus, then hepatitis B antiviral treatment should be carried out in a timely manner.
