Hepatitis B is a viral infection that specifically attacks the liver, and it can be either acute (short-term) or chronic (lifelong). Many people, especially initially, have no symptoms, but it can cause fatigue, jaundice (yellowing skin/eyes), abdominal pain, and dark urine. For chronic cases, management involves regular monitoring and potent antiviral medications (like Tenofovir or Entecavir) to suppress the virus and prevent liver damage (cirrhosis or cancer). It is crucial to see a Hepatologist or a Gastroenterologist specializing in liver diseases at a reputable hospital with a hepatology or liver institute. The long-term cost of monitoring and generic antivirals can range from $1,000 to $5,000+ annually. Essential guidance includes vaccinating close contacts, avoiding sharing razors/toothbrushes, practicing safe sex to prevent transmission, and absolutely avoiding alcohol and unnecessary medications to protect your liver health.
