ABIM Endocrinology study plan

Classify diabetes subtypes (type 1, type 2, LADA, MODY, secondary, gestational) using autoantibody, C-peptide, and clinical clues across 20 written vignettes.

Apply ADA diagnostic thresholds for A1c, fasting plasma glucose, 2-hour OGTT, and symptomatic random glucose, stating when confirmatory retesting is mandatory.

Individualize A1c targets for older adults, pregnancy, CKD, and hypoglycemia-unaware patients, writing the justification for each target chosen.

Interpret a CGM report using time in range, time below range, glucose management indicator, and variability, then convert it into three concrete therapy changes.

Sequence type 2 medication selection by dominant comorbidity (ASCVD, heart failure, CKD, obesity, cost) and defend each choice in a written comparison table.

Calculate basal-bolus insulin doses using carbohydrate ratio and correction factor across 10 worked dose-adjustment problems.

Differentiate DKA from HHS and write a stepwise protocol covering fluids, insulin infusion, potassium replacement, and bicarbonate use.

Stage diabetic kidney disease, retinopathy, and neuropathy using eGFR, urine albumin-to-creatinine ratio, and guideline screening intervals.

Rank causes of recurrent hypoglycemia and match each cause to a specific corrective regimen.

Map each anterior pituitary hormone axis to its deficiency syndrome, confirmatory stimulation test, and replacement strategy.

Interpret prolactin, IGF-1, and cortisol testing patterns to separate prolactinoma, acromegaly, and Cushing syndrome.

Distinguish central from nephrogenic diabetes insipidus using water deprivation and desmopressin response patterns.

Outline sellar mass evaluation and the emergency sequence for pituitary apoplexy, including steroid administration before imaging.

Distinguish primary, secondary, and tertiary adrenal insufficiency using ACTH, cortisol, renin, and aldosterone together.

Select and sequence screening tests for primary aldosteronism, pheochromocytoma, and Cushing syndrome while naming medications that interfere with each test.

Write stress-dose and taper glucocorticoid plans for surgery, sepsis, and chronically suppressed patients.

Assemble a written adrenal crisis checklist covering resuscitation, hyperkalemia management, and fludrocortisone use.

Interpret TSH, free T4, total T3, and radioactive uptake patterns to classify hyperthyroid and hypothyroid states, including subclinical and central disease.

Compare antithyroid drugs, radioiodine, and surgery by indication, and write monitoring schedules for agranulocytosis and hepatotoxicity.

Stratify thyroid nodules by ultrasound risk features and translate Bethesda cytology categories into next-step management.

Apply trimester-specific thyroid ranges and medication adjustment points to pregnancy cases.

Apply ASCVD risk estimation and set LDL, non-HDL, and triglyceride targets for primary and secondary prevention.

Combine statin, ezetimibe, PCSK9 inhibitor, and bempedoic acid therapy by risk tier and statin-intolerance pattern.

Evaluate severe hypertriglyceridemia and pancreatitis risk, specifying fibrate, icosapent ethyl, and dietary actions.

Build a weight-management plan integrating lifestyle, incretin-based pharmacotherapy, and bariatric surgery criteria with comorbidity matching.

Screen for secondary causes of dyslipidemia and for nutritional deficiencies after bariatric surgery.

Work up amenorrhea and infertility by ordering gonadotropins, prolactin, androgens, and pelvic imaging in the correct sequence.

Separate PCOS, hypothalamic amenorrhea, and premature ovarian insufficiency using Rotterdam criteria and match each to management.

Evaluate male hypogonadism with morning total testosterone, confirmatory repeat testing, and contraindication screening before therapy.

Interpret DXA, FRAX, and bone turnover markers, then sequence antiresorptive versus anabolic therapy in osteoporosis.

Diagnose primary hyperparathyroidism and distinguish it from familial hypocalciuric hypercalcemia and vitamin D deficiency.

Re-answer every missed item from weeks 1 through 7, verbalizing the governing rule before each retry.

Complete two 60-question timed mixed blocks spanning all five domains and review each question in full.

Consolidate drug-monitoring intervals, diagnostic thresholds, and screening schedules into a single four-page summary.

Rehearse exam-day logistics including pacing, break scheduling, and flag-and-return strategy.
