Consequently, its use has increased among patients with type 2 diabetes and obesity. Gastrointestinal symptoms are commonly recognized as adverse effects of tirzepatide, while other adverse effects, such as thyroid abnormalities, are rare. This report describes a rare case of unilateral Graves\u2019 disease that developed during treatment with tirzepatide.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>A 59\u2010year\u2010old woman with type 2 diabetes was treated with tirzepatide resulting in marked glycemic improvement and weight loss. During treatment, she developed fatigue and palpitations, initially attributed to the effects of the drug. Further evaluation revealed thyrotoxicosis with suppressed thyroid\u2010stimulating hormone (TSH), elevated free thyroid hormones, and positive autoantibodies. Imaging revealed increased vascularity and technetium\u201099\u2009m uptake confined to the right thyroid lobe, consistent with unilateral Graves\u2019 disease. The patient\u2019s clinical symptoms and thyroid function rapidly improved after initiating antithyroid medications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Although a causal relationship between tirzepatide and the development of Graves\u2019 disease cannot be established, this case highlights the difficulty of recognizing hyperthyroidism during potent glucose\u2010lowering therapy. Thus, thyroid function testing should be considered in patients with type 2 diabetes who experience symptoms such as fatigue or palpitations during treatment with tirzepatide.<\/jats:p>\n
