Claire Foy reveals years-long battle with hidden parasites in her body

Actress Claire Foy revealed she had been living with parasites in her body for years. The discovery came after she experienced unexplained weight loss and persistent hunger. Doctors later confirmed the presence of the parasites, which she believes she contracted while travelling in Morocco.

Foy suspected something was wrong when she began losing weight without explanation. Tests showed parasites had been in her system for at least five years. Instead of relying on weight watchers or diet pills, she decided to overhaul her diet to eliminate them.

Her new routine involves avoiding gluten, sugar, and caffeine entirely. Before the diagnosis, she drank up to 15 cups of tea daily. Now, she follows a strict diet but occasionally makes exceptions when eating out.

The actress has also linked her autoimmune condition to her dietary changes. While she has not shared a full timeline of her recovery, she previously mentioned that the parasites caused significant weight loss before treatment.

Foy's approach focuses on diet rather than medication to manage her health. She remains careful about what she eats, though she allows flexibility in social settings. The long-term effects of her condition and dietary shift have not been detailed further.
