Q. A 30-year-old female aspiring ballet dancer presents to the clinic complaining of recent changes to her skin and hair, along with muscle aches and an unusual sensation in her extremities. Over the last three months, she has noticed a progressive hair loss, skin rashes, and redness in her eyes. Additionally, she reports feeling continuously tired, an unusual sense of sadness, and odd instances where she felt detached from reality. When asked about her diet, she eagerly talks about her high-protein, low-carbohydrate regimen, a large part of which includes a homemade fitness shake made from raw egg whites, consumed multiple times daily.
Her vitals are normal, and her physical examination reveals dermatitis, conjunctivitis, alopecia, and a decreased sensation to touch in both hands and feet.
What is the most likely diagnosis in this patient?
