Claire Foy reveals years of undiagnosed parasite infection

Actress Claire Foy has revealed she unknowingly lived with parasites for years. Doctors discovered the infection after she experienced unexplained weight loss and constant hunger. The issue may have started during a trip to Morocco at least five years earlier.

Foy struggled with severe symptoms before her diagnosis. She lost weight steadily and felt hungry all the time. Tests later confirmed parasites had been living in her system for years.

Instead of antibiotics, she chose to fight the infection through diet. She eliminated caffeine entirely, despite previously drinking up to 15 cups of tea a day. The change took time, but she stuck to a strict eating plan designed to remove the parasites.

Her diet remains carefully controlled even now. She avoids gluten and sugar due to an autoimmune condition. While she follows these rules daily, she occasionally makes exceptions when eating out. The parasite diagnosis led to a permanent shift in her habits, particularly her decision to cut out caffeine for good.

The parasites likely entered Foy's body during her travels in Morocco. Her weight loss and hunger were directly linked to their presence. Since adjusting her diet, she has kept the parasites at bay and maintained stricter control over what she eats.
