What are the causes of various types of hepatitis

Pregnancy complicated with hepatitis, large, easy to relapse, may also have a significant impact on fetal development. To understand the cause of the disease is a matter of urgency, according to the cause of the disease, viral hepatitis can be divided into five categories.

First, liver disease: the most common is the greatest harm to a liver disease, infectious and strong. Hepatitis caused by the virus mainly for the A, B, C, D, E five type. Hepatitis A and hepatitis E virus through intestinal infection, virus contamination of water or food can form a pandemic, but will not develop into chronic, it will not cause cirrhosis, and the disease after a lifetime of immunity. B, C, D liver disease are transmitted by blood, a few can also be due to close contact with patients with saliva, semen, breast milk and other infections, such as between husband and wife, mother and child between each other infection. B, hepatitis C can be converted to chronic, and may be transformed into liver cirrhosis or even liver cancer.
Second, metabolic abnormalities hepatitis: metabolic abnormalities refers to the liver of fat, protein and other substances metabolism is not normal, resulting in liver function and liver structure changes in the disease. It is less harmful than liver disease, but moderate to severe fatty liver than hepatitis B is more likely to cause liver fibrosis, liver cancer, so the prevention and treatment of fatty liver as important.
Third, alcoholic liver injury: Alcoholic hepatitis refers to the alcohol content in the liver than the normal proportion, resulting in the main component of alcohol ethanol on liver cell damage and the impact of normal liver function. Clinical more common, such as alcohol liver, alcohol liver is more dangerous than a serious liver disease.
Fourth, drug-induced liver injury: As the name suggests, this type of hepatitis and drug-related. Drug-induced liver injury has two conditions: one is the toxic effects of drugs, such as a variety of anti-cancer drugs may directly or indirectly damage the liver cells. Another is related to the patient's specific constitution, which means that a certain person with a drug after the liver injury occurs, the incidence is low, but unpredictable. Allergic to penicillin allergies, asthma, allergic rhinitis and other allergic constitution of patients should be used with caution or put an end to the use of sulfonamides, aminosalicylic acid and other drugs to avoid liver injury.
5, autoimmune hepatitis: more rare, and more with other autoimmune disorders accompanied. Of the five categories of the most familiar of course, is liver disease, because it is caused by a group of hepatitis virus damage to the liver-based infectious diseases, transmission and its harm is more serious. As for the alcoholic hepatitis and drug hepatitis, just quit drinking and disable the relevant drugs, can stop liver damage. The incidence of autoimmune hepatitis is relatively low, hormones and immunosuppressive drugs can control the disease.
