What causes purple lips

When something is wrong with our body, our lips can also warn us, such as through the color of our lips. We should pay attention when our lips turn purple. Purple lips may be a problem with the lungs or heart, which is usually caused by a decrease in oxygen content in the blood. We should go to the hospital for a comprehensive examination in time. Of course, some people have purple lips since birth, which is a sign of illness. Let's take a look at the specific reasons:

① Purple lips are called cyanosis in medicine. Cyanosis of the lips is mainly caused by a decrease in the oxygen content of hemoglobin in the blood. It is common in patients with lung and heart problems, such as chronic obstructive pulmonary disease and some asthma. In this case, lack of oxygen in the body can cause purple lips. In addition, in terms of the heart, when acute left heart failure occurs, the patient will have pulmonary edema and insufficient nutrients in the body, which will cause cyanosis of the lips.

② Purple lips are mainly caused by a decrease in the oxygen content of hemoglobin in the blood. Common causes are lung problems, such as chronic obstructive pulmonary disease and asthma, and heart problems, such as acute left heart failure.

③ Purple lips are mostly a sign of heart failure, which can be seen in congenital heart disease, cor pulmonale, and coronary heart disease. There may be lower limb edema, fatigue, and wheezing. It can be diagnosed through electrocardiogram, cardiac color ultrasound, coronary angiography and other examinations. It can also be seen in symptoms caused by severe respiratory diseases and airway obstruction, which require a chest CT examination. It is recommended to see an internal medicine doctor for examination, identify the cause of the disease and provide reasonable treatment, provide good care, pay attention to rest and balance work and rest, and avoid overeating.

④ There are many causes. This situation is mainly caused by reduced blood oxygen content, such as pneumonia, high altitude areas, heart failure, asthma, cor pulmonale, constipation, abdominal pain and diarrhea, and excessive fatigue. It is recommended that you go to the hospital for a check-up and determine the cause before symptomatic treatment.

⑤ Purple lips. Problems with the heart and lungs can affect the amount of oxygen transported through the blood in the human body. If the amount of oxygen is significantly reduced, it will first be manifested in purple lips. If it happens after exercise, the problem should not be serious. In addition, if you eat too much pickled vegetables, the effect of nitrite will cause enterogenic cyanosis.

⑥Of course, some patients with purple lips do not suffer from these diseases, but rather from "blood stasis". Normal people's lips are rosy, moderately dry and wet, smooth and shiny. If there is a problem with the body, the lips will give you signals in time.
