According to one theory, this is because your body has been used to a higher “normal”, and treats a drop in blood glucose, even if it is still in the normal range, as low. This can be particularly noticeable when you first change your diet or insulin dose.
I suspect in some cases, it can be from your body producing too much insulin right after a meal, resulting in a big drop that corrects itself by the time you are noticing symptoms. In other cases, I think it could be a result of significant hormonal changes.
I experience lows that aren’t low when I first become pregnant and after I stop being pregnant. It can be very frustrating, especially if you are not sure what is causing it. For me, the worst part is the horrible moodiness that occurs with the shaking and sweating.
In my personal experience, it tends to go away after a half an hour or so, but treating it like a regular low and having a small carb snack can make it go away more quickly. It also is very dependent on what I eat in the morning. If I have a low carb breakfast, such as my old standby of eggs and hash browns, I won’t notice those symptoms, but if I have cereal or oatmeal, I can almost always count on it happening within an hour of my meal.
What about you? Have you experienced low blood sugar symptoms when your blood sugar is normal? How do you handle it?
