Can you stay up late with viral hepatitis?
Patients with viral hepatitis should avoid staying up late at night, because the liver rests and detoxifies during night hours. Staying up late might lead to liver function damage. For a healthy individual, staying up late might cause mild liver function abnormalities the following day. Over time, if a patient with viral hepatitis continues to stay up late, their liver function may repeatedly become abnormal. Even if their virus status is negative and they are just carriers, their long-term poor lifestyle habits could lead to the onset of hepatitis. Therefore, it is crucial for patients with viral hepatitis to avoid staying up late and drinking alcohol.
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.
What indicators are checked for viral hepatitis?
For viral hepatitis, the primary index to check is liver function. If there are obvious abnormalities in liver function, further clarification is needed to determine what caused these liver function abnormalities. The most common pathogens include Hepatitis A, B, C, E, D, and non-A non-E, etc. Typical hospitals carry out tests for Hepatitis A, B, C, and E. Hepatitis A and E are acute hepatitis; if IgM antibodies are positive, it can indicate a recent infection. However, if IgG antibodies are positive, their significance is not very substantial. If Hepatitis B or C causes the liver damage, further tests such as HBV-DNA, HCV-RNA, etc., need to be conducted to clarify the cause of the liver condition. Additionally, regular follow-up exams like ultrasound and AFP are required.
What fruits to eat for viral hepatitis?
Viral hepatitis patients can eat most fruits as there are not many restrictions, and fruits generally are good to eat. Fruits contain a high amount of vitamins, especially vitamin C, which can help repair the liver when consumed by patients. However, for some special patients, especially those with cirrhosis or liver failure who are at risk of bleeding, or even after a significant gastrointestinal bleeding, eating hard, difficult-to-digest fruits is not beneficial for recovery. Consuming hard fruits might exacerbate bleeding, and eating hard-to-digest fruits might lead to symptoms such as upper abdominal discomfort, poor appetite, and nausea or vomiting after eating.
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.
Can you have intercourse after hepatic cirrhosis caused by hepatitis B?
Liver cirrhosis caused by hepatitis B, if not treated with standard antiviral therapy, is very likely to test positive for the hepatitis B virus. HBV-DNA is a good indicator of the hepatitis B virus; if HBV-DNA tests positive, then it is contagious. The main transmission routes of hepatitis B include mother-to-child transmission, blood and body fluid transmission, and sexual transmission between spouses, though this route carries a relatively lower risk. Why is this the case? Firstly, the spouse may already have hepatitis B surface antibodies, which are protective antibodies providing immunity against hepatitis B. Secondly, when adults are infected with hepatitis B, most can acutely clear the virus, preventing the chronic manifestation of the disease.
Is hepatitis B cirrhosis serious?
After infection with the hepatitis B virus, it may cause repeated inflammatory damage to the liver. If hepatitis B is not well-controlled, it can lead to the development of liver cirrhosis. The symptoms of liver cirrhosis mainly manifest as repeated fatigue, poor appetite, yellowing of the eyes, yellow urine, and discomfort in the upper abdomen after eating, etc. If the cirrhosis due to hepatitis B is in a compensated stage, such as liver cirrhosis suggested by ultrasonography and mild abnormalities in liver function, and the symptoms are not very severe, this type of compensatory cirrhosis, relatively speaking, has a decent prognosis. With standard antiviral treatment, many patients can maintain a state of liver cirrhosis. However, if treatment is not further pursued and damage progresses, leading to decompensated liver cirrhosis, or if ascites has already developed, or even gastrointestinal bleeding occurs, then its prognosis is relatively poor, and this situation is very serious.
Symptoms of decompensated cirrhosis due to hepatitis B
Hepatitis B virus infection repeatedly leads to severe damage to the liver. If chronic hepatitis is not actively controlled, cirrhosis may occur. A symptom of decompensated cirrhosis mainly manifests as ascites, gastrointestinal bleeding, portal hypertension, and some people exhibit symptoms of hepatic encephalopathy. The presence of these complications indicates that the patient has reached the stage of decompensated cirrhosis. Patients in this stage often exhibit distinct jaundice, dark urine, abdominal distension after eating, and the presence of ascites with a positive shifting dullness. Additionally, some patients may experience vomiting blood, black stools, liver coma, and other related symptoms. Once these symptoms appear, it indicates that the prognosis for the patient is relatively poor.
Is hepatitis B cirrhosis contagious?
If hepatitis B is not well controlled, it can easily lead to the occurrence of cirrhosis. After the hepatitis B virus infects the human body, it causes repeated inflammatory damage to the liver, with recurring abnormalities in liver function. If during this period there is no formal antiviral treatment or lack of attention, it is very likely to lead to the development of cirrhosis. Once cirrhosis from hepatitis B occurs, it is generally irreversible. Cirrhosis due to hepatitis B is also an infectious disease, and its level of infectiousness mainly depends on the presence of the virus. If the viral load is positive, indicated by a positive HBV-DNA test, then it is infectious. If HBV-DNA is negative, then it is not infectious. Therefore, whether cirrhosis from hepatitis B is infectious primarily depends on the level of HBV-DNA.
