A topic that comes up frequently nowadays is the use of diabetes technologies with exercise. When I surveyed close to 300 active individuals with diabetes, more than 60 percent used an insulin pump (which is well above the national average), but even more of these exercisers—over 75 percent—wear a continuous glucose monitoring (CGM) device (1). The technology fervor has grown even louder since the FDA recently granted approval in the United States to an implantable, three-month CGM sensor called Eversense (made by Senseonics). Can active people benefit from using these CGM and other devices, especially when active?

Mrs. Wilson is woman who is 71 years of age, African American and has excess weight. She has come to your clinic today for a new patient visit. She recently moved to the area to live with her daughter and is concerned about her diabetes care plan. She was diagnosed with type 2 diabetes 12 years ago at a wellness check through routine screening. In hindsight, she wonders if maybe she “went undiagnosed for a while” because she “didn’t get to the clinic very often and was having some problems with frequent urination at night” before she was screened. She currently takes metformin, glyburide, captopril, pravastatin, and aspirin, and has recently titrated to.6 U/kg/day insulin NPH as a nightly basal dose. Her current A1C goal is less than 7.5% and she has been working hard to get to that level. However, for the first time her life, she is finding herself to be nauseated and irritable in the morning, but always feels better after a little breakfast. She states she feels “pretty good for her age,” although she occasionally has “a little chest tightness when walking more than 4 or 5 blocks.” Last time she remembered to check her glucose was a few days ago. GHer postprandial glucose was “a little high” at 214 mg/dL. Her office A1C is 8.6%. Based on what you know about the patient, what is the most likely cause of her morning distress? A. Hyperglycemia B. Hypoglycemia C. Anxiety D. Cognitive decline Follow the link for the answer.
