The skin is the largest organ of the human body, with a total weight of 5-15% of the body weight, a total area of 1.5-2 square meters, and a thickness of 0.5-4 millimeters depending on the person or the part. Skin covers the whole body, it makes the body of various tissues and organs from physical, mechanical, chemical and pathogenic microbial invasion. The skin acts as a barrier in two ways: on the one hand, it prevents the loss of water, electrolytes and other substances from the body; on the other hand, it prevents the invasion of harmful substances from outside. It maintains the stability of the body’s internal environment and plays an important protective function in physiology, while the skin is also involved in the body’s metabolic processes. Skin has several colors (white, yellow, red, brown, black, etc.), mainly due to race, age and different parts of the body. Recognize Hepatitis B through the skin: In the early stage of liver disease, there are usually no typical specific symptoms, but the following pathological manifestations of the skin often appear, which should attract people’s attention. 1. Orange-colored skin, commonly seen in severe hepatitis. 2.Yellowish green or brownish green skin, often caused by intrahepatic biliary stasis, intrahepatic or extrahepatic biliary obstruction. 3.Yellow skin with progressive deepening, mostly due to pancreatic head cancer, biliary system carcinoma or primary hepatocellular carcinoma. Deepening of skin pigmentation: the face will be gray and dark, especially around the orbits. This is called hyperpigmentation in medicine. This is because of the disorder of melanin metabolism caused by liver disease. Hepatitis B virus carriers in the end in life should pay attention to what problems, so that the condition does not develop to the bad side? 5, abdominal wall varicose veins, normal people abdominal wall veins are usually not visible, or only vaguely visible. When the liver disease, due to increased resistance to venous return in the abdomen, bruising and varicose, can appear to the umbilicus as the center of radial extension to the surrounding area, serious cases can be accompanied by abdominal wall edema, skin tightness. 6, spider nevus, is a vascular nevus formed by the expansion of the end branches of small arteries in the skin, commonly found on the face, neck, forehead, back of the hand and shoulder. It is bright red in color and varies in size from the size of a pinhead to several centimeters. It is characterized by a central point surrounded by radially expanding capillaries, resembling a spider, so it is called a spider nevus, which is also known as crab’s claw in Chinese medicine. When the center of the nevus is pressed with the end of a thin rod, the whole nevus disappears and appears again after it is released, which can be distinguished from other vascular nevi. According to the information, 85% of men with spider nevus have different degrees of liver lesions, about 30% of which are cirrhosis. 7, the palm of the hand appears mottled redness, especially the palms of the two sides of the edge of the big and small interosseous muscles and the end of the finger is the most obvious, which is characterized by the fading of the color when pressurized, and then appeared when depressurized. This is mostly a specific manifestation of acute and chronic hepatitis and cirrhosis of the liver, so it is called liver palm in medicine. >>>About Hepatitis B patients must also stomach do you know? It is generally believed that the occurrence of spider nevi and liver palms is related to the increase of sex hormones in the human body. In the case of liver disease, the sex hormones secreted by the body cannot be effectively degraded and inactivated in a timely manner, which leads to congestion and dilation of small arteries on the surface of the body. When any one or more of the above skin vascular manifestations occur for unknown reasons, you should go to the hospital in time to check if you are suffering from liver disease.
