The causes of black lips are the following three most common

Different lip colors often indicate different diseases in people's bodies. Among them, black lips is the most common symptom. So, what are the causes of dark lips?

1. Digestive system

After clinical research, it was found that the cause of black lips is closely related to diseases, especially problems with the digestive system. If the digestive system is not fully functional or if we suffer from long-term constipation, diarrhea and other symptoms, our lips will turn black. There are many reasons that lead to digestive system problems, such as poor eating habits or incorrect living habits, which can all cause digestive system diseases. Therefore, experts remind us that we should try our best to develop good living habits and eating habits in our daily lives.

Especially some patients who have constipation, diarrhea and other conditions for a long time should be examined and treated as soon as possible. At the same time, experts remind that most patients with symptoms such as constipation and diarrhea have loss of appetite, etc. These are specific manifestations of digestive system malfunction.

2. Blood circulation

Once the blood circulation is poor or blocked, it will cause the lips to turn black. Therefore, when the lips turn black, you should also consider whether it is due to problems with blood circulation. Research has found that if the patient has problems with blood circulation, it will usually induce various cardiovascular and cerebrovascular diseases, the most common of which are heart disease, anemia, etc. In severe cases, it may even induce major diseases such as stroke. Therefore, when the lips appear black, etc., you should check your blood pressure health as soon as possible.

Especially in some places with extremely cold climates, many people's lips will turn blue and purple due to poor blood circulation at the end of the body. This can also induce various major diseases in the long run. Therefore, for this group of people, in addition to taking basic warming measures, they should also eat more foods that have the effect of replenishing blood and qi to promote normal blood circulation.

3. Kidney function

Many people don’t know that if there is a problem with our kidney function, it will also cause our lips to change color. For example, kidney deficiency, nephritis, uremia, etc. are all common kidney diseases. Clinical studies have found that the lips of these patients are mainly purple-black in color. There are also some patients with chronic adrenal insufficiency whose lips are mainly black in color. Therefore, experts remind that after the lips become darker, in addition to checking the health of the above-mentioned organ tissues, you should also pay special attention to kidney problems.

In addition to kidney damage that can cause the lips to darken, long-term excessive smoking, drinking, or polyps in the digestive tract can also cause the lips to darken. Therefore, patients should find out the cause before receiving effective treatment. When it comes to the question of what causes black lips, these are common reasons.
