Hyperthyroidism in the elderly is not uncommon and often presents in an atypical manner. Signs and symptoms are often non-specific and may be easily attributed to aging or diseases in other organ systems, leading to delayed diagnosis and complications. Drugs such as beta-blockers may also mask the signs of hyperthyroidism. The diagnosis can be easily made and treatment leads to a euthyroid state. Atrial fibrillation and other cardiovascular complications can be avoided and prognosis is excellent. Family physicians are often the first point of contact for these patients and will be managing such cases in their practice. We therefore need to be familiar with the presentation, diagnosis and treatment. We describe a case that illustrates the non-specificity of symptoms in hyperthyroidism in elderly patients.
