How common is dark urine in hepatitis A?

Hepatitis A can affect the liver's handling of bilirubin, a yellow substance made when old red blood cells are broken down. When bilirubin builds up in the bloodstream and passes into urine, the urine may look tea-coloured, brown, or noticeably darker than usual. Pale stools, yellowing of the eyes or skin, nausea, reduced appetite, tiredness, and discomfort under the ribs may occur alongside it. Dark urine alone does not establish the cause; dehydration, medicines, food pigments, and other liver or urinary conditions can also change urine colour.

A person can have hepatitis A before the colour change is noticed, and the shade can vary with fluid intake. The symptom describes how hepatitis A may present; it does not show that every episode of dark urine is hepatitis A.

Arrange a medical assessment if new dark urine lasts, returns, or appears with yellow eyes, pale stools, nausea, or unusual tiredness. A clinician may ask about recent illness, food and drink, medicines, travel, and contact with anyone who was unwell, then use blood tests to assess liver inflammation and bilirubin. Until assessed, drink fluids as tolerated, avoid alcohol, and do not start extra medicines or supplements without checking that they are suitable for your liver.

Seek urgent medical help for confusion, extreme sleepiness, repeated vomiting, severe or worsening abdominal pain, inability to keep fluids down, bleeding, or rapidly deepening yellowing. These features can signal a more serious illness or dehydration and need prompt examination. If you are pregnant, have known liver disease, or take regular medicines, contact a clinician sooner about new dark urine.

Ask whether your symptoms fit hepatitis A, which tests are needed, whether any current medicine should be paused, how to protect household contacts, and which changes should prompt an urgent call. Mention when the urine first changed and whether your stools, eyes, appetite, or energy have changed.
