Claire Foy, the acclaimed actress known for her role as Queen Elizabeth II in 'The Crown', has opened up about her struggle with internal parasites. In an interview on the 'Table Manners' podcast, Foy revealed that she had been suffering from these parasites for at least five years before discovering the issue. She described the experience as gross and exhausting, as she was constantly losing weight without understanding the cause. Foy's doctor informed her that the parasites traveled in pairs, which she found equally disturbing. To address the issue, she opted for dietary changes rather than antibiotics, giving up caffeine and adopting a more restricted diet.
