‘The Crown’ Actress Reveals She May Have Had Parasites in Her for 5 Years
Claire Foy endured a five-year gastrointestinal parasite infection from Morocco, adopting a strict diet and avoiding antibiotics, including giving up caffeine, to manage the condition.
- On February 4, 2026, Claire Foy disclosed on the Table Manners with Jessie and Lennie Ware podcast that she battled parasites for "at least five years."
- Foy said she thinks the infection began while she was in Morocco, and medical commentary suggested Giardia intestinalis is a likely culprit given her description and travel context.
- Foy recalled doctors using stool samples to identify the infection, saying, `I got told by the doctor, gross, absolutely rank.`
- Foy said she declined strong antibiotics and instead altered her diet, giving up caffeine despite drinking `at least 15 cups of tea a day, and then I had my two coffees`.
- Clinically, parasites can produce symptoms like weight loss, diarrhoea, and stomach cramps, and most parasitic infections are treated with antiparasitics or medication combinations, Cleveland Clinic notes.
