1. What is Hepatitis B?
Hepatitis B is a viral infection that attacks the liver, caused by the Hepatitis B Virus (HBV). It can be either acute or chronic. Acute hepatitis B is a short-term illness, while chronic hepatitis B is a long-term infection that can lead to serious health problems, including liver damage, liver cancer, and cirrhosis. Understanding what Hepatitis B is, is the first step in protecting your health.
2. What are the Symptoms of Hepatitis B?
The symptoms of acute Hepatitis B can vary from mild to severe. Some people, especially young children, may not experience any symptoms at all. If symptoms do occur, they usually appear 1 to 4 months after infection. Common symptoms include:
- Abdominal pain
- Dark urine
- Fever
- Joint pain
- Loss of appetite
- Nausea and vomiting
- Weakness and fatigue
- Jaundice (yellowing of the skin and eyes)
It’s important to note that chronic Hepatitis B may not cause symptoms for many years until significant liver damage has occurred. If you suspect you have been exposed to Hepatitis B or are experiencing any of these symptoms, consult a healthcare professional immediately. Early detection is key to managing the infection and preventing long-term complications. If you have any questions about your health or well-being, WHAT.EDU.VN provides a platform to ask and get answers for free.
