This is the 1st month that I have been using the Dexcom Seven Sensor CGM. I like it so far and what I notice on the graphs is quite interesting, but most aggravating. I see that when I eat, regardless of how much sugar/carbs I take in, I spike up really really high. For example, this morning @ 6a, I woke up 46, I had 65gm carbs and by 10a, I was 305. In the mornings I take 50 units of Lantus, 5 units of Novolog & 60mcg of Symlin. In the last 2 weeks, I've been taking my insulin after I eat because it seems to be working better, but I can not completely avoid the spikes.
Before I started taking the Symlin, I used to have this weird experience that no one can explain: I would eat my meal (usually this happens with dinner) and 8 hours later, I would feel that I still had the food sitting in my stomach and I would be burping it up. In terms of my numbers, what would happen is that at dinner, I would be ~145, crash about 30 minutes afterwards to 60, test at night and be ~130, then wake up in the morning upwards of 260+. My thoughts are that the food I am eating is not being digested fast enough and when it does, my body "hyper-absorbs" it. In regards to dinner and the insulin, it feels like my body is utilizing the insulin much faster than normal and therefore it is gone when I start digesting the food (hence why I've started taking the insulin after my meal). Even though the Symlin has taken away the full feeling that I was experiencing for long periods of time, it has not helped the spikes that occur. I will be visiting a GI doctor in the coming weeks, but I'm curious to see if anybody else has experience such feelings. Thanks.
