Any suggestions on random rapid rises in blood sugar? Can a 100 point rise in 20 minutes be due to a basal rate that is too low? It seems physiologically difficult to explain in that way but we are seeing it more and more frequently. Sometimes for no reason, sometimes 2-3 hours after a meal ( not a high fat meal). He drops to a normal range post prandial and then begins to rise back up. And then he becomes insulin resistant and corrections are difficult. My son is 10 and only about 70 pounds. We are running about 30 units a day now with basal rates that average 0.500/hr. His A1C used to be around 6.8, but now we are at 7.5 most recently. I am frustrated and out of ideas.
