The American Board of Internal Medicine (ABIM) Endocrinology, Diabetes and Metabolism (EDM) Board Certification is the definitive credential signifying a physician's expertise in the diagnosis, treatment, and management of complex endocrine disorders. This rigorous, peer-developed certification validates that a diplomate possesses the specialized knowledge and clinical judgment required for the highest standard of patient care in areas including diabetes mellitus, thyroid disease, pituitary and adrenal disorders, metabolic bone disease, reproductive endocrinology, and lipid metabolism. Achieving certification demonstrates a commitment to lifelong learning and mastery of a rapidly evolving field. It is a voluntary achievement beyond state licensure and initial internal medicine certification, representing the pinnacle of professional accomplishment in the subspecialty. The credential is time-limited, requiring ongoing participation in Maintenance of Certification (MOC) to ensure certified endocrinologists remain current with medical advances, thereby reinforcing public trust and clinical excellence.
Sample Questions
Choose an answer and explore the explanation to see how practice works.
A 60-year-old woman has TSH below 0.01 and a palpable 2-cm thyroid nodule. Free T4 is mildly elevated. TRAb is negative. What test best distinguishes autonomous nodule from destructive thyroiditis or Graves pattern?
A patient has low TSH, high free T4, low thyroglobulin, absent uptake, and access to a relative's levothyroxine prescription. There is no neck pain. What is the most likely cause?
A patient with a pituitary macroadenoma has low free T4, low testosterone, low IGF-1, and morning cortisol 3 mcg/dL. He asks which hormone to replace first. What is the safest sequence?
A 61-year-old woman with type 2 diabetes, prior myocardial infarction, BMI 36 kg/m2, A1c 8.0%, eGFR 74, and no heart failure is taking metformin. She wants weight loss and fewer injections than basal-bolus insulin. Which add-on best matches the 2025 ADA risk-based approach?
A 69-year-old man with atrial fibrillation has TSH below 0.01, free T4 mildly high, negative TRAb, and a 3-cm right thyroid nodule. Radioiodine uptake is high only in the nodule with suppression of the remaining gland. What is the diagnosis?
