“Graves disease” behind glucose fluctuation

At 16:30 p.m., in the consulting room of Department of Endocrinology, there was only one patient left. As the queue system rang, a middle-aged woman came in. She was a common patient, and had been diagnosed with type 2 diabetes mellitus (T2DM) for five years. She often took oral biguanides and sulfonylurea to control blood glucose, and her blood glucose level was relatively stable. When she came in, I noticed that she was worried and upset, and I thought maybe that was ascribed to the long waiting.
