Question from Forest Lake, Queensland, Australia:

My seven year old son was diagnosed with diabetes less than two years ago. We have been able to keep his blood sugar levels under tight control, so far. Recently, he’s been having readings of 4 to 7 mmol/L [72 to 126 mg/dl] before bedtime. I give him his usual bedtime snack, which could consists of a biscuit with half a glass of low fat milk. However, he is waking up with a very high blood sugar level, between 11 and 15 mmol/L [198 and 270 mg/dl]. What am I doing wrong? Can other elements be effecting his readings, like growth hormones?

My son takes two insulin shots every day, one before breakfast and the other before bedtime. The injections are of two types of insulin. In the morning he takes six units of Protophane with four units of NovoRapid. At night, he takes seven units of Protophane and four units of NovoRapid. It might be worth mentioning that I just increased his nighttime dose of Protophane from six to seven units, a week ago, in hopes of solving this morning high issue but it has not worked. I try not to test my son too many times, but I am so worried about highs that I sometimes end up testing him up to eight times a day. My son has maintained an A1c of less than 7.0 for the last year and half except for the last one we did two weeks ago that was 8.3.
