Why Blood Sugar Levels Rise Overnight

get the scoop When you go to bed, your blood sugar reading is 110, but when you wake up in the morning, it has shot up to 150. Why does this happen? To understand how blood sugar levels can rise overnight without your eating anything, we have to look at where glucose comes from — and where it goes — while we sleep. During the day, the carbohydrates we eat are digested into glucose and absorbed into the bloodstream. Some of this glucose goes to the liver, where it is stored for later use. At night, while we are asleep, the liver releases glucose into the bloodstream. The liver acts as our glucose warehouse and keeps us supplied until we eat breakfast. The amount of glucose being used is matched by the amount of glucose being released by the liver, so blood sugar levels should remain constant. what is the dawn phenomenon? A rise in blood sugar level between approximately 3 A.M. and the time you wake up is called the “dawn phenomenon.” The liver is supposed to release just enough glucose to replace what is being used, and insulin works as the messenger to tell the liver how much is enough. But if there's not enough insulin (as with type 1 diabetes), or if there's enough insuli Continue reading >>

    Liver Dump: In a Nutshell!

    I've read bits and pieces about this liver dump theory/condition, and would like someone, anyone to give me a short synopsis, or snapshot of just what exactly a "Liver dump" is; how to prevent it one from happening; and the pros and cons of a liver dump!
    Thanks for the info, it will be nice to have a short and sweet answer to what it is and how to know if it happens.

    Liver Dump is when your body thinks it is in need of fuel - glucose that is stored in the liver is released to fuel you up. Pros - not a thing a diabetic wants. Cons - high BGL in the morning. I can modify my glucose release by eating a small bowl of cereal with real sugar as a bed time snack (I use insulin). Don't think it can be prevented at all.
    This is not a part of our normal attempt to get control - it usually happens while we sleep because that is the longest time we go without eating. Clear as Mud? Sorry

    Liver dumps are insulin the result of resistance of the liver. At various times as others have described - most notably at dawn - signals are sent out for the liver to release glycogen from its stores as glucose. In a normal system, the first release of glucose triggers a release of insulin from the pancreas. Shepherding glucose into cells for energy is not insulin's only job. It also 1) pushes fat into storage and inhibits its release and 2) encourages storage of glucose as glycogen in the liver AND inhibits or stops its release.
    So, in a type 2, normal hormone signals which would only cause a slight (and beneficial) rise in blood sugar cause a higher spike. This is because the liver responded to those other hormones but its response to insulin is impaired - hepatic insulin resistance - and so it releases more than it should, i.e., doesn't know when to stop.
    I avoid this by keeping my glycogen stores depleted. Depleting them is a prerequisite for getting into ketosis and since I stay in ketosis virtually all the time, no liver dumps. If I come out of ketosis - even though still eating very much "low-carb" and with good numbers throughout the day, Dawn Phenomenon will return and if breakfast is delayed, my BG will drift slowly up instead of its normal down or steady state.
    Others have various other tricks for getting around the broken hormone signaling/response.
