How common is fatigue in glandular fever?

Fatigue is a very common presentation of Glandular Fever and can remain after the acute illness settles. People may also have a sore throat, swollen glands, fever or reduced appetite.

Glandular fever can leave energy low during the infection and recovery. A person may manage a small task but then need substantial rest, and progress can vary from day to day. Returning to normal activity too quickly can make recovery harder. Fatigue that is severe, prolonged or changing should be reviewed, because another infection, anaemia, sleep problem or medication effect may also contribute.

Rest when needed, drink enough fluids and choose easy, nourishing meals. Pace school, work and exercise by increasing activity only when your energy is stable. Avoid contact sports and strenuous exertion while advised by your clinician because glandular fever can enlarge the spleen. Do not share drinks or utensils while unwell, and follow individual advice about returning to normal routines.

Get urgent help for severe or worsening abdominal pain, especially under the ribs, trouble breathing or swallowing, fainting, severe dehydration or confusion. Arrange a review if fever returns, jaundice appears, or fatigue is worsening instead of gradually easing. Sudden severe symptoms should not be dismissed as routine recovery.

Ask when it is safe to return to work, school, exercise or contact sport. Ask how to pace recovery, whether your symptoms need testing, and which abdominal, breathing or swallowing changes require immediate help.
