liver disease face
Introduction
Introduction Hepatic disease is more common in patients with chronic hepatitis and cirrhosis, and is one of the common clinical manifestations of patients with liver disease. The face of liver disease is characterized by dry skin, dark complexion and darkness. The pigmentation of the skin on some patients' faces and other exposed parts may be more obvious, especially the pigmentation around the eyelids. The facial features of the liver disease are that the color of the facial skin is gradually darkened, the face is black and the gloss is not elastic, the skin is dry and rough, and even the "bronze" face appears; some patients are especially dark around the eye circle, a bit like "panda eyes"; some patients Small telangiectasia appears on the face or tip of the nose, like a delicate network. Medically, these characteristic changes in the face of patients with liver disease are called "hepatic disease face", which is caused by an increase in melanin production due to liver dysfunction.
Cause
Cause
The mechanism of the appearance of liver disease is not fully understood. Some scholars believe that the increase of estrogen in patients with chronic liver disease weakens the inhibitory effect of thiol groups on tyrosinase in the skin. As a result, tyrosinase increases the amount of tyrosine into melanin. To blacken the skin. Some scholars believe that the adrenal function of patients with cirrhosis is reduced, the function of adrenal medulla complex adrenaline is reduced, affecting pigment metabolism, pigment entering the skin, making the skin black. In addition, the sympathetic inhibition of melanogenesis in patients with cirrhosis is weakened, which promotes the production of melanin and enters the skin, resulting in a liver disease.
