In this interactive, online forum, expert faculty Thomas J. Weber, MD, discusses the case of a 65-year-old woman who presents for an annual evaluation. She reports some fatigue and an increase in forgetfulness, but overall she is in good health. As part of the exam, a chemistry profile is done and everything is normal except for her calcium levels, which are elevated. What testing would you do next? How would you confirm that this patient has primary hyperparathyroidism? How would you care for this patient? Watch the case and join the discussion about identifying and managing patients with primary hyperparathyroidism.
