A 24-year-old woman presents to your office for a refill of her combination oral contraceptive medication. She reports that four months ago, her hemoglobin A1c was 6.1%, and her endocrinologist advised her to take precautions for her prediabetes. Two months ago, she was diagnosed with a hepatoma. She smokes one pack of cigarettes per day. Her blood pressure today is 130/85 mm Hg, and physical examination is otherwise unremarkable. What is the next step in the management of this patient?
