The Dawn Phenomenon

Posted by admin in Prescription Diabetes Drugs, Weight Loss on May 12th, 2009

If you have diabetes, you have probably experienced a rise in blood glucose that naturally occurs between 3:00 a.m. and 8:00 a.m. This is known as the dawn phenomenon.

What causes the dawn phenomenon Well, basically it is caused by a complicated release in hormones that occur naturally in the body. People without diabetes have the luxury of simply secreting the needed amount of insulin in their sleep and waking up feeling great. Those of us with diabetes do not have that luxury, so if we do experience the dawn phenomenon, we could end up with higher than normal blood glucose all day long.

The good news is that the effects of dawn phenomenon vary and are treatable. Some mornings the blood glucose may be normal and therefore no treatment is needed. Other mornings if it is high, levels can even out throughout the day with good diabetes management. Although hormones are the major culprit of the dawn phenomenon, sometimes the insulin simply runs out before morning (especially for those with type 1) and your basal rate needs to be adjusted with your doctor. The best way to know for sure if this is a problem for you is to test your blood glucose at bedtime, again around 3:00 a.m. (yes, I said 3:00 a.m.), and then again around 8:00 a.m. I know this sounds inconvenient, but it is the best way for your doctor to know what treatment option is the best for you. If you blood sugar is normal at bedtime, but then rises at 3:00 a.m., and again at 8:00 a.m., then you are definitely experiencing the dawn phenomenon.

If this is the case for you, make an appointment with your doctor and make some changes. Trust me, your days will go much smoother when you can get a good nights rest and wake with a normal blood glucose.
