Yellow lips should pay attention to the problem of hepatitis, which is a collective term for inflammation of the liver. It is usually caused by a variety of pathogenic factors, such as viruses, bacteria, parasites, chemical toxins, drugs, alcohol, autoimmune factors, etc., so that the liver cells are damaged, the function of the liver is damaged, causing a series of uncomfortable symptoms in the body, as well as abnormal liver function indicators. Due to the different causes that trigger hepatitis, although there are similar clinical manifestations, there are often significant differences in pathogenesis, serology, mechanism of injury, clinical course and prognosis, extrahepatic damage, diagnosis and treatment. It is important to note that most of the hepatitis we usually refer to in our life refers to viral hepatitis caused by hepatitis A, B, C and other hepatitis viruses. The causes of hepatitis may vary, most commonly caused by viruses, in addition to autoimmune causes. Alcohol abuse can also cause hepatitis. There are acute and chronic hepatitis. Viral hepatitis is a group of infectious diseases caused by many different hepatitis viruses, mainly liver damage, and is one of the most widespread and dangerous infectious diseases in the world. Viral hepatitis is ranked by the World Health Organization (WHO) as the ninth most deadly disease in the world. According to the pathogenic diagnosis, there are at least five types of hepatitis viruses, namely hepatitis A, B, C, D and E viruses, which cause viral hepatitis A, B, C, D and E, respectively, namely hepatitis A (hepatitis A), hepatitis B (hepatitis B), hepatitis C (hepatitis C), hepatitis D (hepatitis D) and hepatitis E ( hepatitis E). Another type of hepatitis, called hepatitis G, is less common. AlcoholicHepatitis is a liver disease caused by chronic excessive alcohol consumption. Its main clinical features are nausea and vomiting, jaundice, liver enlargement and pressure pain. It can be complicated by liver failure and upper gastrointestinal bleeding. Autoimmune hepatitis is a chronic autoimmune disease of the liver that used to be relatively common but is now rare. three times more women than men between the ages of 20 and 40 years suffer from it. The cause of autoimmune hepatitis is unknown, and it is suspected that antigens from environmental toxins, bacteria (such as Salmonella spp.) or viruses (such as the viruses of hepatitis A, B, C and D or the measles and herpesviridae) may contribute to the disease. These pathogens may contribute to an autoimmune flare-up, but at the time of onset these pathogens are no longer found. In autoimmune hepatitis, the liver loses the ability to be self-compatible.
