I am 18 with Type 1 Diabetes. I am going to college. I use a short-acting insulin, Novolog, and a 24-period insulin, Lantis. I give Novolog with each meal, and Lantus when I go to bed. I am having troubles with my sugars in the morning. I wake up at 7am, and eat breakfast. I give my shot immediately after eating breakfast, around 7:20. I test my sugar before I eat breakfast and it is normally good. Then at 8am, I head to school. When I arrive at school around 9am, I test my sugar, which is usually pretty high (200-300). I have classes back-to-back until 1:00. Around 12:00 I start feeling like my sugars are low. Some days, I have to eat something quick between classes I feel so low. I don't have time to test my sugars between classes. At 1pm, my sugars are usually 60-80. In the morning, I've tried giving extra Novolog to make sure that I was giving enough for that meal. This only resulted in the same 9am sugar, and a lower 1pm sugar. I have tried decreasing my Lantus the night before, thinking that its too much, because my sugars are decreasing throghout the day. This didn't change anything. On a non-school day, I didn't notice my sugars reducing during the day, so I don't believe that my Lantus dosage is incorrect.
The only thing I can think of that can cause this low sugar at 1pm is the absorbtion rate of my Novolog from breakfast. This would cause the insulin to start working after the sugar has been absorbed, and a low around lunch. Does this sound feasable? I would appreciate any help, Thanks.
