Viral hepatitis primarily includes liver inflammation and damage caused by pathogens such as hepatitis A, B, C, E, etc. Their clinical symptoms are quite similar, mainly characterized by fatigue, poor appetite, nausea, vomiting, abdominal bloating after eating, jaundice, and dark urine. In cases of chronic liver diseases, such as chronic hepatitis caused by hepatitis B or C, if prolonged, it can also lead to facial features typical of liver disease, spider angiomas, and enlarged spleen. Once cirrhosis occurs, the patient may experience hepatic encephalopathy, gastrointestinal bleeding, abdominal distension with water accumulation, and significant abdominal tenderness. Thus, the symptoms of viral hepatitis relate to both the cause of the hepatitis and the type of hepatitis.

Do you need a blood transfusion for viral hepatitis?

The treatment of viral hepatitis generally does not require blood transfusion. The primary treatment methods for viral hepatitis include ensuring plenty of rest, eating smaller and more frequent meals, and paying attention to diet. Additionally, medications that protect the liver, reduce enzyme levels, and alleviate jaundice can be used. For viral hepatitis caused by hepatitis B or C, formal antiviral treatment is also necessary. If liver damage is extremely severe, leading to liver failure and very high bilirubin levels, artificial liver treatment can be administered. Artificial liver treatment is of two types: one is plasma exchange, commonly referred to as a blood transfusion, and the other is protein adsorption; both of these methods are relatively effective.

How to treat viral hepatitis

Viral hepatitis is caused by various viruses, primarily affecting the liver and characterized as an infectious disease. Clinically, the main symptoms include loss of appetite, nausea, abdominal discomfort, pain in the liver area, and fatigue. Some patients may also experience jaundice and fever. Common causes include five types of hepatitis viruses: Type A, B, C, D, and E. Generally, hepatitis B and C can lead to chronic hepatitis. Acute hepatitis is primarily treated symptomatically, while chronic conditions like hepatitis B and C usually require antiviral treatment.

How is viral hepatitis transmitted?

Viral hepatitis comes in many types, with its main pathogens including hepatitis A, B, C, D, E, and others. Each type targets different transmission pathways; for example, hepatitis A and E are primarily transmitted via the digestive tract. They can spread through fecal-oral transmission, and ingesting contaminated food can lead to the dissemination of hepatitis A or E. For hepatitis B, the main transmission routes include mother-to-child transmission, blood and body fluid transmission, and close personal contact can also lead to the transmission of hepatitis B. As for hepatitis C, the primary transmission method is through transfusion of blood or blood products, and patients on dialysis are a high-risk group for hepatitis C infection.

What are the types of viral hepatitis?

Viral hepatitis, in terms of etiology, mainly includes hepatitis caused by several viruses such as Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E, non-A, and non-E. In terms of clinical classification, it mainly includes five types: acute hepatitis, chronic hepatitis, liver failure, cholestatic hepatitis, and hepatitis cirrhosis. Among them, Hepatitis A and Hepatitis E can easily cause acute hepatitis, and Hepatitis B can also lead to the occurrence of acute hepatitis. The most common types of chronic hepatitis are Hepatitis B and Hepatitis C, which can progress to cirrhosis if not promptly controlled. Liver failure can be caused by these viruses as well, with liver failure caused by Hepatitis B being the most common.

How is viral hepatitis transmitted?

Different types of viral hepatitis have different routes and methods of transmission. Hepatitis A and E are mainly transmitted through the fecal-oral route via the digestive tract. Hepatitis B and C are transmitted through blood, sexual contact, and from mother to child. Generally, transmission through casual contact is rare. Most cases of hepatitis B are transmitted from mother to child. Hepatitis C is more commonly transmitted through needle stick injuries and blood transfusions. In terms of prevention, hepatitis A can be prevented by vaccination, and hepatitis B can be prevented through vaccination as well.
