Claire Foy Reveals She Lived With Parasites for Five Years

The Crown star Claire Foy has opened up about a surprising health struggle, revealing she lived with parasites for five years after contracting an infection abroad. The Emmy- and Golden Globe-winning actress shared the experience on the Table Manners podcast, explaining how the condition forced her to make lasting changes to her diet and lifestyle.

A Hidden Health Battle

Foy, 41, said she believes she picked up the parasites while traveling in Morocco. “I kept losing weight and I didn’t know what was going on,” she recalled. Doctors eventually diagnosed her with parasites, which she described as “gross” and “absolutely rank.” Rather than taking strong antibiotics, Foy opted for alternative treatments and dietary adjustments. One major change was giving up caffeine, which she says she has avoided ever since.

Managing Gut Health and Autoimmune Issues

The actress also revealed she has an autoimmune condition, which requires her to limit gluten and sugar to reduce inflammation. “I don’t actually eat gluten or sugar… except when I go out for dinner,” she explained. “It doesn’t have an impact on me. It’s just because I have an autoimmune condition.” Her candid comments highlight how long-term health issues can shape everyday choices, even for high-profile stars.

Career Highlights Amid Challenges

Despite her health struggles, Foy has continued to thrive professionally. She won two Emmy Awards and a Golden Globe for her portrayal of Queen Elizabeth II in The Crown. She also starred in Women Talking (2022) and the upcoming adaptation of H Is For Hawk. Looking ahead, Foy is set to appear in two new films: the Enid Blyton fantasy The Magic Faraway Tree and the black comedy Savage House, opposite Richard E. Grant.

Understanding Parasites

According to the NHS, parasitic infections such as roundworms, hookworms, and tapeworms can be contracted through contaminated food, water, or surfaces. Symptoms often include unexplained weight loss, stomach pain, or persistent digestive issues. While most infections are treatable, they can linger undetected for years, as in Foy’s case. Preventive measures include washing hands and produce thoroughly, drinking bottled or boiled water in high-risk areas, and deworming pets regularly.

A Story of Resilience

Foy’s openness about her health journey underscores the importance of awareness and self-care. Her ability to balance personal challenges with a flourishing career continues to inspire fans worldwide.
