Hepatitis B can cause similar symptoms to other liver diseases, including other types of hepatitis. However, most people with hepatitis B show no symptoms at all. Hepatitis B symptoms are more common in the acute phase than the chronic phase.
Symptoms of Acute Hepatitis B
Between 30% and 50% of people with acute hepatitis B (aged over 5) experience symptoms. Children under 5 and people with serious health problems rarely show any symptoms. Symptoms of acute hepatitis B range from very mild or so serious they require a hospital stay. They include:
- Low-grade fever.
- Lost appetite.
- Pain in muscles, joints, and the abdomen (usually in the top-right, where the liver is).
- Bloated stomach.
- Dark-colored urine.
- Clay-colored feces.
- Jaundice (skin and eyes appear yellow).
Symptoms of Chronic Hepatitis B
Most people who develop chronic hepatitis B have no symptoms at all, even if they had symptoms during the acute phase. People who experience symptoms tend to show signs of acute infections or advanced liver disease. In addition to all the symptoms of acute hepatitis B, the symptoms of chronic hepatitis B can include:
- Depression and irritability.
- Confusion and difficulty concentrating.
