I must agree with Annalise that any reading below 80 can make you feel pretty awful even if not considered dangerously low. Most doctors consider a reading below 70 or 80 (different doctors use different numbers for the low end of normal) to be hypoglycemic, and I can assure you that I feel absolutely awful when readings get down to 50's and 60's even though I can function very normally. I have been told by doctors that some diabetics who suffer from frequent hypoglycemia (I am one of those) can have little spasms of the heart muscle when hypoglycemic, for I have had sensations like this when hypo. So reactive hypoglycemia sounds like a possibility to me. A reading of 114 only tells you what the glucose level is at that moment, not if it was lower before rising to 114 or if it is dropping a the time you tested from 114 to something lower. I think many of us insulin-dependent diabetics can feel when our glucose levels are sharply dropping even if the glucometer says the number is OK. In my case, the feeling is ALWAYS correct, and I can count on needing some juice in about 15 minutes to a half hour if I get that sensation but find the glucometer telling me that my sugar levels are normal. So you may be feeling a drop in action.
Also, the palpitations you mention could be an indication of thyroid problems. You may want to have your physician check out your thyroid function with a simple blood test, for the thyroid can cause all sorts of odd symptoms, including heart palpitations, when not producing the correct amount of hormone for your needs. This is a simple thing to test for and may be worth checking out.
The volunteers of this forum will have much more information for you. But I think I can safely say that your morning reading of 58 would be considered low. My son, who is 7, has Type 1 diabetes, and we give him juice for any reading below 80 in order to bring his glucose levels up and prevent a severe episode of hypoglycemia (i.e. pass out).
southj,
i'm no doctor so i'm not even going to venture a guess. Have you ever brought up these problems with your doctor? There seem to be various possiblities going on which only a doctor may discern.
The doctor may order some new different blood tests to furher clarify the proper issue, that i could only guess at.But if you do go to see a doctor bring in copies of the times you checked your blood sugar for him to see.
But if i were in your shoes i'd also feel that hypoglucemia was the cause, especially where it is resolved by eating. But i've never had blood sugars go low so close after a meal, generally only when my insulin is peaking. Maybe others who read this will have experienced this will leave a comment about their resolving the problem.
i do know that if it involved the feelings of low blood sugar i'd want it to end.
hope you eventually find the answer, bret
