Does hepatitis B cause fatigue?

Hepatitis B can cause an inflammatory illness that leaves you drained even after ordinary activities. Fatigue may occur with dark urine, pale stools, itchy skin, or yellowing of the eyes and skin. Some people have few symptoms, so energy levels alone cannot show whether the virus is present.

Low energy is also common with poor sleep, anaemia, thyroid problems, infections, stress, and medication effects. A clinician may ask how long it has lasted, examine you, and use blood tests to look for liver inflammation and other explanations.

Pace tasks, take planned rests, and keep a regular sleep routine. Choose simple meals and drink enough fluids to support recovery. Gentle activity can be reasonable if it does not worsen symptoms, but stop and rest if you feel faint or unwell.

Avoid alcohol and check medicines, supplements, or herbal products with a clinician or pharmacist. Do not share razors or toothbrushes, cover bleeding cuts, and arrange medical advice if fatigue is new, persistent, or affecting work and daily care.

Get urgent help if fatigue comes with confusion, unusual sleepiness, severe abdominal pain, repeated vomiting, fainting, bleeding, yellowing that is rapidly worsening, or inability to keep fluids down. These symptoms need prompt assessment rather than home observation.

Ask whether hepatitis B testing is appropriate, what other causes of fatigue should be checked, how to pace activity, and how to protect people who may have had close contact with blood or body fluids.
