How serious is hepatitis A?

Hepatitis A affects the liver. Some people have mild illness or no noticeable symptoms, while others develop marked tiredness, nausea, reduced appetite, fever, abdominal discomfort, dark urine, or yellowing of the skin and eyes. Recovery can take time even after the acute illness improves. Older adults and people with existing liver disease may need closer medical supervision. Symptoms alone cannot show how inflamed the liver is, and a person with one symptom does not necessarily have hepatitis A. A clinician uses the history, examination, and appropriate blood tests to assess the cause and severity.

Arrange medical advice if hepatitis A is suspected or you have had a relevant exposure. Rest, drink enough fluids if you can, and discuss medicines and supplements before taking them because the liver processes many products. Avoid preparing food for others until a clinician advises that it is appropriate, and follow careful hand hygiene. A Liver Function Test may be part of the assessment. Hepatitis A Vaccination can help prevent infection in suitable situations; it is not a treatment for established illness.

Seek urgent care for confusion, unusual sleepiness, severe or repeated vomiting, inability to keep fluids down, bleeding, severe abdominal pain, or rapidly worsening yellow skin or eyes. Contact a clinician promptly for Dark Urine, persistent Nausea, Loss of Appetite, or Feeling Generally Unwell, especially if several symptoms occur together or you have liver disease. Prompt assessment helps distinguish hepatitis A from other liver, digestive, or medication-related problems.

Ask which tests are appropriate, whether medicines or supplements should be paused, how to protect household contacts, and what changes would mean you should return urgently.
