Recurrent Graves' disease post SARS-CoV-2 infection

Abstract

A 22-year-old woman was diagnosed with thyrotoxicosis 8 weeks after the diagnosis of a mild COVID-19 infection. She had reported significant unexplained weight loss after testing positive for COVID-19, but failed to seek medical attention. She recovered well from COVID-19, but presented to the emergency department with worsening symptoms of thyrotoxicosis after 2 months. In view of her known history of previously treated Graves' disease, a recurrence of Graves' thyrotoxicosis was suspected. A positive thyroid stimulating hormone receptor antibody confirmed the diagnosis. She was started on carbimazole and propranolol treatment with significant improvement of her symptoms.
