History of Present Illness
Yi-Ling Wang is a 49-year-old woman who presents to her new physician complaining of feeling tired, lethargic, and "not thinking straight" for the last 6 months. She has seen her previous primary care physician several times and has been told that her symptoms are probably due to anemia from menorrhagia, stress, depression, and/or impending menopause. She was not entirely satisfied with those explanations, and despite treatment with iron (and resultant improvement of her anemia), a hormonal contraceptive to help regulate her menstrual cycle, and an antidepressant, her symptoms have slowly worsened. Two years ago at a pharmacy student-run health fair, she was told her TSH was 6.2 μIU/mL (6.2 mIU/L) and her total cholesterol was 246 mg/dL (6.36 mmol/L). Y-L's primary care physician felt the TSH value was compatible with subclinical hypothyroidism and therefore could not explain her symptoms at that time. She has been wondering if she really is depressed and why the depression medication is not helping. Over the past few months, she has also noticed that her skin seems a little more dry and itchy and that she has difficulty keeping warm even in warm weather. Finally, she asks you what is good for constipation since the Chinese herbs her mother gave her are not helping.
