I ate a few donuts this morning. After I felt shaky, dizzy, weak, nervous, tired. Could I have had a hypoglycemia/diabetes?

I ate a few donuts this morning. After I felt shaky, dizzy, weak, nervous, tired. Could I have had a hypoglycemia/diabetes?

No: In my 35 years of practice, I have never seen a case of reactive hypoglycemia. The disorder doesn't exist, if you're overweight the symptoms are a natural response to your glucose level returning to normal. A glucose tolerance test (if you've had one) is not and never will be a valid diagnostic test for hypoglycemia. Don't waste your money o GTT or any fad diets of treatments. Lose wt if heavy. ...Read more

Glucose meter: I am sure you have a friend who has a home glucose meter. To ease your anxiety us a meter to test your blood sugar. If you test fasting and if your blood sugar is between 70-120 then odds are you do not have diabetes. Also, if you do have diabetes do not freak out as long as levels are below 250. If greater than that, see if you can get an earlier appointment and get on low carb diet. ...Read more
