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.

The relationship between HCV infection and glomerular diseases has gradually increased in the last decade, and it is now believed that HCV-related kidney damage mainly includes cryoglobulinemic MPGN, non-cryoglobulinemic MPGN, and membranous glomerulopathy. membranous nephropathy (MN). Fulminant hepatitis-like syndrome is a group of syndromes with fulminant hepatitis-like manifestations of non-viral hepatitis. Including three signs: 1 tetracycline toxic hepatitis, taking a large number of tetracycline antibiotics can cause acute fatty liver, but more pregnant women; 2 pregnancy acute fatty liver, the patient is mostly 20-30 years of age primigravida, 3Reye syndrome (encephalopathy fatty liver syndrome), refers to the virus, poisoning and metabolic disorders caused by brain edema and liver, kidney and other organs fatty deposits. However, if cured, the liver can be completely restored to normal. The symptoms of this group include acute onset, severe nausea, vomiting and abdominal distention, bleeding tendency, and impaired consciousness.
