Type One is a mysterious disease (condition) I've had it since I was 16, 69 years ago. I've had Medtronic pumps, now a 780G with sensors. The Sensor 3 was inaccurate to the point of madness (saying 8.4 when I was 4.2 and visa versa) Sensor 4 is stable and accurate. When I was on 3, I had to BG test about 8 x a day to avoid high or low disaster. With Sensor 4, once a week. Medtronic 780 pump is astonishing good at night. (8am always between 5 and 6. Daytime very different. very high after lunch and very spiky. The 780 gives loads of corrective doses which never lower my daytime blood sugar levels. I used to eat 20gm of nut muesli every morning with kefir and my BG would shoot up as if I was eating pure sugar. Lunch maybe one slice of wholemeal toast and some cheese, with 3 units and then another spike up to 12 or 14. The only way down was to tell the pump I had eaten another 25gms of carb and it would give a couple more units. To reduce the spikes, I now don't eat breakfast or take a bolus and everything stays calm between 9.30pm and 12.00 before lunch. Then the spikes start again. Today the I told the pump I was eating 20gms (1 piece of toast) and it gave me 1.5 units. by BG shot up and the pump automatically gave me 1.5 extra units in 9 small increments. My BG went up till 3.00pm when I told it I had eaten another 12gms (which I hadn't to get the BG down. For 12mgC it gave my 1.525units. Now at 5.30, my BG has gone down to 7.2. I will change the ratio tomorrow to give me 3.5units for 20 gms of carb.
I find the ratios change quite a lot and I need to pay more attention to adjusting (with care) but more often. My last 30 days average is 80% in range in a very stressful period. Normally it's 82% in range. Total daily insulin 30.5. Carbs about 100 a day. Not much exercise recently. Just trying to live another year to get to 70 years with Type One and happy.
