Prevention and care

Avoid exposed raw aquatic plants and use safe water. Specific treatment is prescribed according to the examinations and the stage of the disease.

Practical issues

Do all liver moats have the same treatment?

No: several different parasites reach the liver or bile tracts. Their identification is important before choosing a drug.

Preparing for an exchange with a professional

  • Cresson, aquatic plants and water
  • Meal dates and symptoms
  • Liver, stool and imaging

Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.
