Patient background
Doug is a 68-year-old male who was diagnosed with type 1 diabetes 47 years ago.
Current treatment: Degludec 40 units daily at bedtime, Aspart 1 unit per 10 grams carbohydrate plus correction of 1 unit per 50 mg/dL over 150 mg/dL at meals
Current A1C: 7.2%
Scenario
Doug has been living with type 1 diabetes since early adulthood when he was diagnosed. He has been on multiple daily insulin injections and using a blood glucose meter (BGM) to check his glucose numbers since diagnosis and his outlook is, “if it’s working, why change what I’m doing?” Doug eats well-balanced meals and feels he’s doing everything he can to take care of his diabetes.
Sometimes, Doug is unsure if he is experiencing hypoglycemia and it worries his wife that he’s not as aware of the symptoms as he used to be. He is stubbornly independent and doesn’t want much help from others, especially when it comes to diabetes management.
Why Dexcom G7 was prescribed
Doug told his primary care provider that he feels like his glucose numbers aren’t as steady as they used to be, and he can’t figure out why. His doctor told him that Dexcom CGM could give them both insight into what’s happening with his glucose levels in between fingerstick checks with his BGM.
Doug was curious to see how CGM could help, and decided to give it a try since it’s covered by Medicare.*
How Dexcom CGM helped
For the first time since being diagnosed, Doug was able to get a clearer picture of what was happening with his glucose levels throughout the day and night. He had no idea that eating oatmeal with banana slices for breakfast caused his glucose to spike to over 250 mg/dL, and it took a few hours to get back in range.
Before CGM, Doug only saw the numbers in the low 100s before he ate and the 100s before lunch. Doug admits, “I was under the impression that all my blood sugars were in range based on the numbers I was seeing on my meter, and my A1C being around 7%. I can now see that I have some pretty big spikes after what I thought were healthy meals. I’m going to experiment to see what I can eat for breakfast that won’t cause such a spike.” Doug was surprised that he felt comfort in being able to always see his current glucose number and the direction it’s heading. This caused him to worry less when he was busy and not wanting to interrupt his day to use his BGM.
Doug’s wife was glad he eventually allowed her to follow his Dexcom G7 data and be alerted if he gets an Urgent Low Alarm. Doug likes that he can decide what alerts his wife receives, and that she’s not nagging him as much about his numbers because she can see them on the Dexcom Follow app.¶
