Which of the following is the most likely diagnosis?? A: Polycystic ovarian syndrome, B: Insulinoma, C: Exogenous hypoglycemia, D: Binge eating disorder, E: Cushings syndromen,  <response>: This is a clinical case scenario describing a 53-year-old woman with recent symptoms of lightheadedness, left arm weakness, tremors, palpitations, and diaphoresis.
