Why Do My Lips Always Turn White or Purple?
Generally speaking, this phenomenon can be triggered by physiological factors, such as cold environments or malnutrition; it can also be indicative of certain pathological conditions, like anemia, heart failure, or pulmonary hypertension. To accurately determine the cause, it is recommended to seek medical attention as soon as possible for professional diagnosis and treatment.

1. Physiological Causes: In cold weather, if adequate warmth is not maintained, blood circulation may be affected, leading to changes in lip color. Malnutrition is also a common cause. Picky eating or dietary偏食 may result in a lack of necessary vitamins and minerals in the body, such as Vitamin C, which can affect metabolism and the circulatory system, subsequently causing lips to appear white or purple.
2. Pathological Causes: Anemia, especially iron-deficiency anemia, is a common cause of changes in lip color. It can be caused by improper diet and is often accompanied by symptoms such as pale skin and dizziness. Heart failure results from cardiac dysfunction, leading to abnormal blood flow and insufficient oxygen supply. In such cases, purple lips may be a sign of oxygen deprivation. Pulmonary hypertension is a chronic condition with complex causes, but one of its symptoms is white lips, accompanied by dyspnea and chest tightness.
In addition to these common causes, abnormal lip color may also be associated with other health issues such as congenital heart disease. To avoid these health problems, attention should be paid to maintaining a balanced diet with sufficient protein and calcium intake, such as from eggs and milk, in daily life. Additionally, appropriate exercise helps to strengthen physical fitness and immunity.
If you notice persistent or worsening white or purple lips, do not ignore these signs. Seeking medical attention promptly can help identify the underlying issue and take appropriate treatment measures. Maintaining a healthy lifestyle, paying attention to diet and exercise, is an effective way to prevent these problems. I hope these suggestions can be helpful to you in maintaining good health and a radiant complexion.
