Answers to Frequently Asked Clinical Questions
This course provides answers to frequently encountered questions across the spectrum of endocrinology, including:

How do I decipher diabetes devices?
How should I choose between the new medications for acromegaly and Cushing’s?
When a pituitary lesion is found incidentally, what could the diagnosis be, and what diagnostic tests should I order?
Do I need to treat a low TSH if the free T4 and T3 is normal and the patient feels fine?
Is there a new goal for TSH during pregnancy?
When should I repeat a screening bone density test?
When should I start and end an osteoporosis drug “holiday”?What is your approach to obesity-related / functional hypogonadism?
Is there a role for using SERMs (e.g., clomiphene) instead of Testosterone Replacement Therapy (TRT) in hypogonadal men?
How do you monitor hematocrit and manage polycythemia on TRT?
What comorbidities should I screen for with PCOS?
How can I distinguish PCOS from hypothalamic amenorrhea in an athlete?
What is the difference between hormone replacement therapy and menopausal hormone therapy?
How can I tell if a patient with “spells” has a pheochromocytoma?
In a patient with an adrenal incidentaloma, what are the right tests to screen for hormone excess and when should I worry about adrenal cancer?
