What causes a yellowish complexion?

Generally, yellowish facial complexion may be caused by improper diet, irregular作息 (daily routine), jaundice, anemia, cirrhosis, or other reasons. If the above conditions occur, it is recommended to seek medical treatment promptly. Specific analysis is as follows:

1. Improper Diet

Long-term or excessive intake of foods rich in carotene—such as carrots, pumpkin, and citrus fruits—can lead to carotene accumulation in the body, causing the skin to turn yellow. It is important to adjust dietary habits in daily life and reduce consumption of carotene-rich foods.

2. Irregular Daily Routine

Chronic late-night habits and insufficient sleep can disrupt the body's endocrine system, slow down metabolism, and prevent the skin from getting adequate rest and repair, resulting in a yellowish complexion. It is advisable to regulate daily routines, ensure sufficient sleep, and avoid staying up late.

3. Jaundice

Jaundice is caused by elevated bilirubin levels in the blood. Due to impaired bilirubin metabolism, bilirubin concentration in the bloodstream increases, leading to yellowing of the skin and sclera (whites of the eyes). This may be accompanied by symptoms such as loss of appetite and nausea. Treatment under medical guidance may include medications such as ursodeoxycholic acid capsules, ademetionine enteric-coated tablets, and Yinzhihuang granules.

4. Anemia

Anemia can be caused by abnormal hematopoietic regulation, trauma, malnutrition, or other factors. Anemia reduces either the number or quality of red blood cells, impairing their oxygen-carrying capacity and leading to skin discoloration due to tissue hypoxia. Symptoms may also include dizziness, fatigue, and palpitations. Treatment should follow medical advice and may include ferrous sulfate tablets, folic acid tablets, and vitamin B12 injections.

5. Cirrhosis

Cirrhosis can result from hepatitis B, alcoholic liver disease, fatty liver disease, autoimmune hepatitis, and other conditions. Long-standing chronic liver damage impairs liver structure and function, affecting bilirubin metabolism and bile excretion, ultimately leading to jaundice and yellowish facial appearance. Symptoms may include ascites and esophageal-gastric varices. Patients should take medications as directed by physicians, such as vitamin B complex tablets, polyene phosphatidylcholine capsules, and entecavir capsules.

To maintain healthy skin tone, individuals should pay attention to balanced nutrition, ensure adequate sleep, avoid excessive fatigue, and monitor any bodily abnormalities, making timely adjustments through healthy lifestyle practices.
