Yellow face may be caused by physiological factors, liver and gallbladder diseases. 1. Physiological factors: excessive intake of carotenoid-rich foods will lead to high carotenoid content in the blood, which will cause skin yellowing. Its clinical manifestation is skin yellowing without sclera yellowing, mostly in the palm and plantar areas, followed by the face. If the patient is due to hypercarotenemia caused by facial yellowing, immediately stop eating foods that cause carotenemia, you can gradually recover. 2. Liver and gallbladder diseases: Due to abnormal liver function, bile stagnation causes yellowing of the skin and sclera. Therefore, when yellowing of the face occurs, it is recommended to go to the hospital in time to clarify the cause of yellowing of the face in order to give the correct treatment and avoid delaying the condition.
