My husband just started taking insulin May 4th. Last night we checked his sugar 2 1/2 hours after he ate and it was 225. He had his 50 units of insulin right after he checked his sugar. Went to bed and got up around ten to 8. Checked his sugar and it was 239. Why did it go up during the night, he didn't eat anything after he took his shot. He went to bed. This is the first time it has done this. He is not new to being diabetic, he has been for the last 8 or 9 years. He was taking pills and it was fine, he lost almost a 100 pounds and now his sugar is high and had to be put on insulin. We don't understand that. Yes we have changed a lot of what we eat, but don't understand why this happened. His doctor doesn't have any explanation on why. We are thinking of changing doctors because he is getting tired of the run around. We thought if you lose weight and eat right he wouldn't have to be on insulin but it went the other way. He is getting frustrated with it, we have more questions then answers. He is going to talk to a diabetic nurse on the 28th about how to do with food porations and stuff like that. Please help.
