What should you know about liver amoebiasis?

Amoebiasis begins when a person swallows microscopic parasites, usually through contaminated food, water, or hands. The infection may remain in the intestine, but it can sometimes travel through the bloodstream to the liver and form an abscess. Fever, pain under the right ribs, tiredness, sweating, nausea, and reduced appetite can occur; diarrhoea may be present or may have happened earlier.

Symptoms can resemble other liver, gallbladder, or abdominal problems. A clinician may combine an examination with blood tests and imaging, and may test stool or other samples when appropriate. An abscess is not confirmed by symptoms alone.

Arrange medical review if fever and upper-right abdominal pain persist, especially after travel or residence in a setting with unsafe water or sanitation. Take prescribed medicines for the full course. Treatment commonly requires a medicine that reaches the liver followed by an intestinal-clearing medicine, so do not stop when pain improves or use leftover antibiotics.

Drink fluids if you can keep them down, wash hands after using the toilet, and avoid preparing food for others while you have diarrhoea. Use safe drinking water and thoroughly wash produce. A clinician may arrange follow-up to check that the liver infection has resolved.

Seek urgent care for severe or rapidly worsening abdominal pain, repeated vomiting, fainting, confusion, difficulty breathing, a rigid abdomen, or yellowing of the skin or eyes. Fever with marked weakness or dehydration also needs prompt attention. Do not wait for diarrhoea to appear before seeking help; liver involvement can occur without ongoing bowel symptoms.

Ask which tests will distinguish a liver abscess from another cause, which medicines are needed in sequence, whether close contacts need assessment, and how follow-up will confirm recovery.
