Currently, viral hepatitis is divided into five types: Hepatitis A virus, Hepatitis B virus, Hepatitis C virus, Hepatitis D virus, and Hepatitis E virus. All five types of viral hepatitis are nationally designated infectious diseases. Among them, Hepatitis A and Hepatitis E are acute in onset, with a minority of Hepatitis E cases developing into chronic Hepatitis E. They are mainly seen in children and the elderly. Additionally, Hepatitis B, Hepatitis C, and Hepatitis D are primarily chronic in nature. Their modes of transmission also vary.

Dietary care for viral hepatitis

Patients with viral hepatitis generally have noticeable gastrointestinal discomfort symptoms, such as fatigue, poor appetite, nausea, vomiting, and bloating after eating. Therefore, it is advisable for patients with viral hepatitis to maintain a low-fat, light diet. Vegetables and fruits are fine to consume, but greasy foods, such as meat, are not recommended. If meat is desired, white meats like fish are preferable, while red meats are advised against. If viral hepatitis is accompanied by other diseases such as hepatic encephalopathy, it is recommended not to consume soy products and eggs. Patients with viral hepatitis often have concurrent gallbladder diseases, so consuming eggs or greasy foods may exacerbate symptoms and cause significant upper abdominal discomfort.

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.

Typing of Viral Hepatitis

Viral hepatitis mainly includes Hepatitis A, B, C, D, E, etc., among which Hepatitis A and E are acute infections. Generally, there is no long-term damage to the human body after infection; recovery of liver function suffices. Hepatitis B and C infections are prone to becoming chronic, leading to chronic hepatitis B and chronic hepatitis C, respectively. These chronic infections can easily lead to cirrhosis and liver cancer. Among them, the carrier rate of HBsAg in hepatitis B is about 7%, and there are approximately 9.6 million people with hepatitis C in China. Therefore, the incidence rates of hepatitis B and C are relatively high, and if there are abnormalities in liver function, it is crucial to check for these diseases.

Is viral hepatitis airborne?

Viral hepatitis cannot be transmitted through the air, and different types of viral hepatitis are transmitted through different routes and have different clinical symptoms. The characteristics of the disease vary; for example, hepatitis A and hepatitis E are primarily transmitted through the digestive tract, via the fecal-oral route. This typically occurs after consuming food or water contaminated with hepatitis A or E virus. Hepatitis B and hepatitis C viruses are mainly transmitted through blood, sexual contact, and from mother to child, with mother-to-child transmission being the most significant route.

Can you smoke with viral hepatitis?

Patients with viral hepatitis should not smoke or drink alcohol. They need to rest well, ensure sufficient sleep, eat light and easily digestible foods, and avoid overly greasy, irritating, or moldy foods. The variety of food should be abundant and nutritionally balanced, with meals distributed reasonably. Moreover, treatment should be tailored according to the type of viral hepatitis, aiming to eliminate the cause of the disease and strengthen liver protection and enzyme reduction. Different types of viral hepatitis require different treatment approaches; for example, hepatitis B and C may need antiviral treatment, whereas hepatitis A and E mainly require enhanced liver protection and enzyme reduction treatments.
