Patients with poor liver function may have liver disease face (dark face, lack of luster, poor elasticity), yellowish face, and some patients may have spider nevus. 1. Liver disease face: poor liver function can lead to the lowering of adrenal cortex function for the middle lobe of the pituitary gland secretion of melanocyte stimulating hormone inhibitory effect decreased, resulting in increased melanin secretion. Therefore, patients with poor liver function can show liver disease face, which is gray, dark, no luster, poor skin elasticity, dark brown pigmentation on both cheeks, and fatigue and emaciation. 2. Yellow face: liver is the main organ of bilirubin metabolism, if the liver function is damaged, the concentration of bilirubin in the patient’s blood increases, which will make the human skin, mucous membranes, sclera and other parts of the body dyed yellow. Therefore, patients with bad liver disease may have yellowish color and yellow eyes. 3. Spider nevus: Patients with liver disease may also have spider nevus on their face. Because when the liver is not good, the inactivation of estrogen by the liver decreases, and the concentration of estrogen in the blood increases, which makes the small arterial capillaries dilate, and then it can be manifested as spider nevus. It is recommended to consult a doctor in time and clarify the cause of the disease under the guidance of a professional physician to avoid delaying the condition.
