Case Report: Quote: |
A 12-year-old boy presents to the emergency department with complaints of weight loss, fatigue, polydipsia, polyphagia, and polyuria. The patient has no medical problems but has many family members with diabetes and hypertension. On examination, the patient is a thin ill-appearing male in no acute distress with normal vital signs. His examination is unremarkable. A urinalysis reveals glucosuria and a markedly elevated fasting blood sugar. The patient is diagnosed with type I diabetes mellitus (insulin-dependent), and is advised by the physician to start insulin therapy. The patient’s parents ask whether oral agents such as sulfonylurea tablets can be used instead of insulin.
