Patients with viral hepatitis, due to abnormal liver function, may experience symptoms such as fatigue, poor appetite, nausea, vomiting, and abdominal bloating after eating. Generally, viral hepatitis does not cause diarrhea. However, for some patients with viral hepatitis, there may be a yellowing of the urine and a whitening of the stool color. This condition may be due to symptoms caused by bile stasis. Therefore, for patients with viral hepatitis, diarrhea is generally not expected, but changes in the color and characteristics of the stool may occur. If a patient with viral hepatitis experiences symptoms like yellowing of the eyes, dark urine, especially if the stool color becomes white, it is important to seek timely medical attention, as jaundice may be present.

Symptoms of viral hepatitis

The clinical symptoms of viral hepatitis are mainly related to liver function. Generally, there are no obvious symptoms when liver function is normal or mildly abnormal. However, when liver function becomes significantly abnormal, symptoms such as fatigue, aversion to oil, nausea, abdominal distension, and poor appetite may occur. Different types of viral hepatitis have different prognoses and severity of illness. Treatment should be tailored to the actual situation, including liver protection, enzyme reduction, and addressing the cause through comprehensive treatment.

How to prevent viral hepatitis

Viral hepatitis can be divided into five types based on the cause: Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E. Hepatitis A and E are mostly transmitted through the fecal-oral route. Therefore, to prevent Hepatitis A and E, it is essential to protect water sources, pay attention to food hygiene, and personal hygiene, and avoid eating raw seafood and similar foods. Hepatitis B and C, on the other hand, are mainly transmitted through blood and bodily fluids. The prevention of Hepatitis C and B primarily involves avoiding unsafe sexual activities with patients with Hepatitis B or C. Hepatitis B can also be prevented through the administration of Hepatitis B vaccine and immune globulin.

What are the symptoms of viral hepatitis?

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.

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.

Transmission routes of viral hepatitis

Different types of viral hepatitis are transmitted through different routes, and preventive measures should start from the cause of the disease, cutting off transmission routes and protecting susceptible individuals. Hepatitis A and E are mainly transmitted through the fecal-oral route, usually by consuming food or water contaminated with the hepatitis A or E virus. Hepatitis B and C, on the other hand, are mainly transmitted through blood, sexual contact, and from mother to child; general contact usually does not lead to infection. Preventive measures include cutting off transmission routes, such as avoiding contact with patients with viral hepatitis, and getting vaccinated against hepatitis B and A.
