Daisy Ridley Graves’ Disease: Health & Ethnicity Facts

When Daisy Ridley stepped into the role of Rey in Star Wars: The Force Awakens, she became an instant icon. But in August 2024, the British actress revealed a different kind of battle — a diagnosis of Graves’ disease, an autoimmune condition that had been quietly affecting her health. Her disclosure pulled back the curtain on hyperthyroidism symptoms that are often dismissed as stress, and sparked conversations about career transparency and the importance of listening to your body.

Full name: Daisy Jazz Isobel Ridley ·
Date of birth: 10 April 1992 ·
Birthplace: Westminster, London, England ·
Notable role: Rey in Star Wars sequel trilogy ·
Diagnosed with: Graves’ disease (hyperthyroidism)

Six key facts about Daisy Ridley’s biography and diagnosis, one pattern: her public health disclosure is rare among A-list actors, and the details offer a clear window into a manageable chronic condition.

What is Daisy Ridley diagnosed with?

Daisy Ridley was diagnosed with Graves’ disease, an autoimmune disorder that causes the thyroid gland to become overactive (Los Angeles Times (major U.S. newspaper)). The condition was identified in September 2023 after she experienced a cascade of symptoms: weight loss, fatigue, tremors, a rapid heart rate, and irritability (BBC News (UK public broadcaster)). At first, she chalked it up to the stress of filming Magpie (Variety (entertainment industry publication)).

What is Graves’ disease?

• Graves’ disease is the most common cause of hyperthyroidism in the United States (ABC News (U.S. television network)).
• It is an autoimmune condition where the body’s immune system mistakenly attacks the thyroid gland, causing it to produce excess thyroid hormone (Healthline (health information publisher)).
• Women are five to ten times more likely than men to develop Graves’ disease, typically between ages 30 and 50 (BBC News (UK public broadcaster)).

The implication: Ridley’s case fits a well-documented pattern, but her willingness to speak openly about it provides a rare celebrity lens into a condition that often flies under the radar.

What illness does Daisy Ridley have?

The illness is hyperthyroidism caused by Graves’ disease. Ridley described the experience as “everything functioning too quickly” — she couldn’t “chill out” (ABC News (U.S. television network)). Specific symptoms she recalled include hot flashes, a racing heart, hand tremors, and significant weight loss (Healthline (health information publisher)).

Symptoms of hyperthyroidism

• Rapid or irregular heartbeat (ABC News (U.S. television network))
• Weight loss despite normal or increased appetite (Los Angeles Times (major U.S. newspaper))
• Fatigue and muscle weakness (BBC News (UK public broadcaster))
• Tremors in hands and fingers (Healthline (health information publisher))
• Heat intolerance and increased sweating (Variety (entertainment industry publication))

The pattern: these symptoms mirror what millions of women experience before diagnosis, yet many attribute them to stress or aging.

Daisy Ridley health journey

Ridley was referred to an endocrinologist after her primary care doctor noticed hand tremors and a racing heart (Healthline (health information publisher)). She now takes daily medication and has adopted a gluten-free diet alongside wellness practices like infrared saunas, cryotherapy, massage, and acupuncture (Variety (entertainment industry publication)). She told Women’s Health that she hadn’t realized how bad she felt until she looked back after treatment (ABC News (U.S. television network)).

What is the life expectancy of someone with hyperthyroidism?

With appropriate treatment, patients with hyperthyroidism — including those with Graves’ disease — have a normal life expectancy (Healthline (health information publisher)). The key is consistent management and regular monitoring of thyroid hormone levels.

Treatments for hyperthyroidism

Typical treatment pathways for Graves’ disease include:

• Antithyroid medications (e.g., methimazole) to reduce hormone production (ABC News (U.S. television network))
• Radioactive iodine therapy to shrink the thyroid gland
• Beta-blockers to manage rapid heart rate and tremors during the initial phase
• Lifestyle adjustments: diet changes (e.g., gluten-free, as adopted by Ridley), stress reduction, and complementary therapies like acupuncture (Variety (entertainment industry publication))

The implication: treatment is not one-size-fits-all, but the options are well-established and effective when followed consistently.

Prognosis with Graves’ disease

If left untreated, hyperthyroidism can lead to serious complications including heart problems (atrial fibrillation), osteoporosis, and a rare but life-threatening condition called thyroid storm (BBC News (UK public broadcaster)). However, with early diagnosis and consistent treatment — exactly what Ridley pursued — most patients achieve remission or long-term control.

The trade-off: managing an autoimmune condition requires ongoing medical supervision and lifestyle discipline, but the outcome is a fully functional life. Ridley’s openness helps normalize that journey for millions of women who share the diagnosis.

Is Daisy Ridley Irish?

No — Daisy Ridley is an English actress. She was born in Westminster, London, and holds British nationality (Wikipedia (open encyclopedia)). However, she does have some Irish ancestry through her father’s line: her paternal great-grandfather was born in Ireland (Wikipedia (open encyclopedia)).

Daisy Ridley ethnicity

• Nationality: British (English) (Wikipedia (open encyclopedia))
• Ancestry: predominantly English, with some Irish and Scottish roots (Wikipedia (open encyclopedia))
• She has referenced being “a quarter Irish” in some interviews, but no official genealogical verification exists (Wikipedia (open encyclopedia))

The pattern: celebrity ethnic ties are often overstated by fans and media, and Ridley’s case is a clear example of thin ancestral threads mistaken for lived heritage.

What part of Ireland is Daisy from?

Ridley herself is not from Ireland — she was born and raised in London. Her Irish connection is distant and patrilineal; the specific county of her great-grandfather’s birth is not publicly documented (Wikipedia (open encyclopedia)).

Is Keira Knightley related to Daisy Ridley?

No known familial relationship exists between Daisy Ridley and Keira Knightley (Wikipedia (open encyclopedia)). The confusion likely stems from their similar physical appearance and shared British acting generation, plus the fact that both have publicly disclosed health conditions (Ridley with Graves’ disease, Knightley with dyslexia).

Keira Knightley disability

Keira Knightley was diagnosed with dyslexia at age six (Wikipedia (open encyclopedia)). Unlike Ridley’s autoimmune condition, dyslexia is a learning difference — not a disease. The two actresses are not related in any way.

The distinction: one condition is autoimmune, the other is neurological — the only common thread is both women are public figures managing visible health narratives.

Comparison of careers

Both actresses rose to fame in the 2010s, but their career trajectories are distinct:

• Keira Knightley: Period dramas (Pride & Prejudice, Atonement), Pirates of the Caribbean franchise, acclaimed for independent films.
• Daisy Ridley: Blockbuster Star Wars trilogy as the lead, followed by smaller projects like Magpie and The Marsh King’s Daughter.

The pattern: both women are British, brunette, and successful in Hollywood, but their health disclosures — and the public’s tendency to conflate them — highlight how celebrity look-alikes can generate persistent myths.

Timeline

• 10 April 1992: Born in Westminster, London (Wikipedia (open encyclopedia))
• 2013: First acting credit in short film Scrambled (Wikipedia (open encyclopedia))
• 2015: Cast as Rey in Star Wars: The Force Awakens (Wikipedia (open encyclopedia))
• 2023: Marries Tom Bateman (BBC News (UK public broadcaster))
• September 2023: Diagnosed with Graves’ disease (Los Angeles Times (major U.S. newspaper))
• August 2024: Reveals diagnosis publicly in Women’s Health interview (BBC News (UK public broadcaster))

The implication: Ridley’s timeline shows a rapid progression from symptom onset to diagnosis to public disclosure — a pace that is unusual for celebrities, who often keep health matters private for years.
