I have been a type 1 for 45 years and been using a Medtronic insulin pump for 12 years. My control has been excellent with A1C in the low 5s for most of this time. I updated my 770G to 780G last year. I didn't like the way the 780 won't let me increase my bolus without lying about my carb count so after several months of frustration I started running the 780G in manual mode (using a CGM sensor but not running Smart Guard). I will say that the 780G in Smart Guard does a great job in reducing the number of low BG I experienced.
At my last meeting with my diabetes health care provider the two endo doctors asked me to go back into auto mode for several months since the Guardian 4 sensor was providing better results for their patients. I agreed to try it again and report back at my next appointment late next month.
I achieved tight control for 40+ years by counting carbs, avoiding snacks, and routine exercise (walking). But my last A1C was mid 6. I blame this on the the way the 780G handles my bolus needs. The pump routinely cuts my bolus by 40-60% for breakfast which cause my blood to regularly rise to 220-260 in the next 90-120 minutes. Slightly smaller adjustments occur at lunch (0-30%) and at dinner (10-30%) but both result in my BG rising higher than I am willing to accept. I am not willing to lie about my carb count to get more insulin to slow blood glucose rise. With the current setup, my pump is delivering 10-15 autocorrections in a feeble attempt to get my BG back into target range and even with autocorrection system, I often go into lunch with a SG of 140-160.
I want to ask other 780G pump users for help in how I can stop these unwanted bolus reductions and how I can convey to my endo. doctors that the 780G in Smart Guard mode is not working well enough for me.
Just to point out a few additional factors in my treatment regime. My carb ratios work well in manual mode. I changed my active insulin duration from 3.5 hours to 2 hours when using auto mode based on recommendations from Medtronic representative. I set a temp basal rate every night just before going to bed to reduce nighttime lows and reduce alarms.
