What does blood in stool feel like with amoebiasis?

The stool may contain visible red blood mixed with mucus, and passing it can be accompanied by lower abdominal cramps or a strong urge to use the toilet. Some people have repeated loose stools or a feeling that they still need to pass stool after going. Nausea, tiredness and fever may also occur. Amoebiasis is caused by a parasite affecting the intestine, but blood in stool has several possible causes, including other infections and bowel conditions. The appearance of blood cannot confirm the cause, and a test may be needed.

Contact a clinician promptly for blood in stool, particularly if diarrhoea is ongoing or you have recently travelled, used unsafe water, or lived with someone who had similar illness. Drink frequent small amounts of safe fluid; an oral rehydration solution may help replace lost water and salts. Wash hands thoroughly after using the toilet and before preparing food, and avoid preparing food for others while unwell. Do not take anti-diarrhoeal medicine without advice when blood or fever is present. A clinician may request stool testing and prescribe treatment based on the result.

Seek urgent care for heavy or continuing bleeding, severe abdominal pain, repeated vomiting, faintness, confusion, very little urine, or signs of dehydration such as a dry mouth and worsening weakness. Children, older adults, pregnant people and anyone with reduced immunity should seek advice early. Keep a note of stool changes, fever, fluid intake and recent food or travel exposures for the assessment.

Could I need stool testing for a parasite or another infection? How should I replace fluids, and which foods or medicines should I avoid? When should I expect improvement, and how can I reduce spread at home?
