no food but blood sugar still increase

my sugars were 8.8 when i woke this morning and as usual I did my levemir, but didn't feel like eating so no novorapid...then a few hours later my sugars were 12.0, why does this happen?sometimes its way worse, for example can jump into 20s! does this mean i should increase my levemir?

This May help. I did once a 36 hour fasting to find out if blood sugar went up in absence of food in the stomach or glucose in the liver.
I found out that when the body can not get glucose it takes it from muscles.
I was told that could not fast at night without risking a hypo.
The truth is that my sugar rises at night without any food.
I use to take 15 units of Lantus before bed time.
Now, I inject 10 units at 6am and 10 at 6pm., my readings have dropped below 10 and keep stable thru out the day. As long as I eat with moderation, and that is reduce the amount of starchy carbs.
Good luck

Whether you should increase your Levemir or not depends on what happens later in the day. If you continue having to take correctional doses of QA in the afternoon, then that would indicate that your Levemir dose in the morning is too low. If it stays stable through the afternoon, then your Levemir dose is probably fine.

If this happens every time that you miss breakfast, then it could be worth having a small amount (1-2 units) of QA with the Levemir in the morning on days that you miss breakfast. There are lots of reasons that your BGs could rise even without food unfortunately. Stress, dawn phenomenon, excitement, climate temperature, illness, menstrual cycle, level of hydration...

I find this as well myself so even if i am not that hungry i eat something small like 2cps and inject and i am fine then for the rest of the morning/day.
