From Allentown, PA, USA:

I have high morning sugars (140-160). I take a dose of Regular before every meal. Before dinner I take 15 units of Regular insulin and about 18 units of NPH. I was told that sometimes too much insulin will cause the body to react and produce its own sugar, thus giving me a high blood sugar in the morning. Should I cut back on the NPH at night, to lower my morning sugar?


You are correct in the belief that low blood sugars can be followed by high sugars without necessarily eating anything sweet. This is because a natural response to low sugars is to produce more from stores in the body. A variety of hormones are responsible for this. However, before you can conclude that this is happening to you, you need more information. You will need to check some 3-4 A.M. sugars and if they are low you should cut your evening NPH. Discuss the results with your diabetes team before making any changes.
