What causes dark lips?

Black lips are quite common in daily life. When this symptom occurs, you must be vigilant. It is often caused by some diseases, even some serious diseases, such as problems with the digestive system, gastrointestinal disorders, restricted blood circulation, problems with the cardiovascular system, etc. In addition, problems with the kidneys and liver are also prone to such symptoms.

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.

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.

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.

4. Hepatitis B

Patients with hepatitis B will also have dark lips, and dark lips are also one of the symptoms of worsening hepatitis B. When the liver is severely damaged, liver function will decline. At this time, the melanin in the human body will increase, causing the lips to darken. Therefore, patients should pay special attention in their daily lives and should regularly check whether their liver function is normal. Once the function is impaired, active and effective treatment should be carried out.
