Hepatitis A


Symptoms & Signs

What are the signs and symptoms of the infection?

Symptoms can range from mild to moderate and include:

  • nausea
  • jaundice. This skin yellowing usually lasts a week or two and is accompanied by darkened urine.
  • malaise, or a vague feeling of illness
  • fatigue
  • pain in the upper right of the stomach
  • hypoglycemia, or low blood sugar
  • diarrhea
  • mild fever
  • a somewhat enlarged and tender liver
  • weight loss as a result of loss of appetite
  • The symptoms gradually improve. Children with hepatitis A often do not have symptoms.

    Rarely, acute fulminant hepatitis, which involves severe liver cell destruction and loss of liver function, occurs. It can be fatal. Symptoms include:

  • an enlarged, painful liver
  • enlarged spleen
  • severe jaundice
  • susceptibility to bleeding
  • encephalopathy, a disorder in the functioning of the brain
  • aplastic anemia in rare cases. Aplastic anemia is a condition in which the bone marrow cannot make enough red and white blood cells.
